				+
			
 
				+gorilla/context is a general purpose registry for global request variables.
			
 
				+
			
 
				+> Note: gorilla/context, having been born well before `context.Context` existed, does not play well
			
 
				+> with the shallow copying of the request that [`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext) (added to net/http Go 1.7 onwards) performs. You should either use *just* gorilla/context, or moving forward, the new `http.Request.Context()`.

				+Package context stores values shared during a request lifetime.
			
 
				+
			
 
				+Note: gorilla/context, having been born well before `context.Context` existed,
			
 
				+does not play well > with the shallow copying of the request that
			
 
				+[`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext)
			
 
				+(added to net/http Go 1.7 onwards) performs. You should either use *just*
			
 
				+gorilla/context, or moving forward, the new `http.Request.Context()`.
			
 
				+
			
 
				+For example, a router can set variables extracted from the URL and later
			
 
				+application handlers can access those values, or it can be used to store
			
 
				+sessions values to be saved at the end of a request. There are several
			
 
				+others common uses.
			
 
				+
			
 
				+The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
			
 
				+
			
 
				+	http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
			
 
				+
			
 
				+Here's the basic usage: first define the keys that you will need. The key
			
 
				+type is interface{} so a key can be of any type that supports equality.
			
 
				+Here we define a key using a custom int type to avoid name collisions:
			
 
				+
			
 
				+	package foo
			
 
				+
			
 
				+	import (
			
 
				+		"github.com/gorilla/context"
			
 
				+	)
			
 
				+
			
 
				+	type key int
			
 
				+
			
 
				+	const MyKey key = 0
			
 
				+
			
 
				+Then set a variable. Variables are bound to an http.Request object, so you
			
 
				+need a request instance to set a value:
			
 
				+
			
 
				+	context.Set(r, MyKey, "bar")
			
 
				+
			
 
				+The application can later access the variable using the same key you provided:
			
 
				+
			
 
				+	func MyHandler(w http.ResponseWriter, r *http.Request) {
			
 
				+		// val is "bar".
			
 
				+		val := context.Get(r, foo.MyKey)
			
 
				+
			
 
				+		// returns ("bar", true)
			
 
				+		val, ok := context.GetOk(r, foo.MyKey)
			
 
				+		// ...
			
 
				+	}
			
 
				+
			
 
				+And that's all about the basic usage. We discuss some other ideas below.
			
 
				+
			
 
				+Any type can be stored in the context. To enforce a given type, make the key
			
 
				+private and wrap Get() and Set() to accept and return values of a specific
			
 
				+type:
			
 
				+
			
 
				+	type key int
			
 
				+
			
 
				+	const mykey key = 0
			
 
				+
			
 
				+	// GetMyKey returns a value for this package from the request values.
			
 
				+	func GetMyKey(r *http.Request) SomeType {
			
 
				+		if rv := context.Get(r, mykey); rv != nil {
			
 
				+			return rv.(SomeType)
			
 
				+		}
			
 
				+		return nil
			
 
				+	}
			
 
				+
			
 
				+	// SetMyKey sets a value for this package in the request values.
			
 
				+	func SetMyKey(r *http.Request, val SomeType) {
			
 
				+		context.Set(r, mykey, val)
			
 
				+	}
			
 
				+
			
 
				+Variables must be cleared at the end of a request, to remove all values
			
 
				+that were stored. This can be done in an http.Handler, after a request was
			
 
				+served. Just call Clear() passing the request:
			
 
				+
			
 
				+	context.Clear(r)
			
 
				+
			
 
				+...or use ClearHandler(), which conveniently wraps an http.Handler to clear
			
 
				+variables at the end of a request lifetime.
			
 
				+
			
 
				+The Routers from the packages gorilla/mux and gorilla/pat call Clear()
			
 
				+so if you are using either of them you don't need to clear the context manually.

				+Package `gorilla/mux` implements a request router and dispatcher for matching incoming requests to
			
 
				+their respective handler.
			
 
				+
			
 
				+The name mux stands for "HTTP request multiplexer". Like the standard `http.ServeMux`, `mux.Router` matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are:
			
 
				+
			
 
				+* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`.
			
 
				+* Requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers.
			
 
				+* URL hosts, paths and query values can have variables with an optional regular expression.
			
 
				+* Registered URLs can be built, or "reversed", which helps maintaining references to resources.
			
 
				+* Routes can be used as subrouters: nested routes are only tested if the parent route matches. This is useful to define groups of routes that share common conditions like a host, a path prefix or other repeated attributes. As a bonus, this optimizes request matching.

				+
			
 
				+## Install
			
 
				+
			
 
				+With a [correctly configured](https://golang.org/doc/install#testing) Go toolchain:
			
 
				+
			
 
				+```sh
			
 
				+go get -u github.com/gorilla/mux
			
 
				+```
			
 
				+
			
 
				+## Examples
			
 
				+
			
 
				+Let's start registering a couple of URL paths and handlers:
			
 
				+
			
 
				+```go
			
 
				+func main() {
			
 
				+    r := mux.NewRouter()
			
 
				+    r.HandleFunc("/", HomeHandler)
			
 
				+    r.HandleFunc("/products", ProductsHandler)
			
 
				+    r.HandleFunc("/articles", ArticlesHandler)
			
 
				+    http.Handle("/", r)
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+Here we register three routes mapping URL paths to handlers. This is equivalent to how `http.HandleFunc()` works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (`http.ResponseWriter`, `*http.Request`) as parameters.
			
 
				+
			
 
				+Paths can have variables. They are defined using the format `{name}` or `{name:pattern}`. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+r.HandleFunc("/products/{key}", ProductHandler)
			
 
				+r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
			
 
				+r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
			
 
				+```
			
 
				+
			
 
				+The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`:
			
 
				+
			
 
				+```go
			
 
				+func ArticlesCategoryHandler(w http.ResponseWriter, r *http.Request) {
			
 
				+    vars := mux.Vars(r)
			
 
				+    w.WriteHeader(http.StatusOK)
			
 
				+    fmt.Fprintf(w, "Category: %v\n", vars["category"])
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+And this is all you need to know about the basic usage. More advanced options are explained below.
			
 
				+
			
 
				+### Matching Routes
			
 
				+
			
 
				+Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+// Only matches if domain is "www.example.com".
			
 
				+r.Host("www.example.com")
			
 
				+// Matches a dynamic subdomain.
			
 
				+r.Host("{subdomain:[a-z]+}.domain.com")
			
 
				+```
			
 
				+
			
 
				+There are several other matchers that can be added. To match path prefixes:
			
 
				+
			
 
				+```go
			
 
				+r.PathPrefix("/products/")
			
 
				+```
			
 
				+
			
 
				+...or HTTP methods:
			
 
				+
			
 
				+```go
			
 
				+r.Methods("GET", "POST")
			
 
				+```
			
 
				+
			
 
				+...or URL schemes:
			
 
				+
			
 
				+```go
			
 
				+r.Schemes("https")
			
 
				+```
			
 
				+
			
 
				+...or header values:
			
 
				+
			
 
				+```go
			
 
				+r.Headers("X-Requested-With", "XMLHttpRequest")
			
 
				+```
			
 
				+
			
 
				+...or query values:
			
 
				+
			
 
				+```go
			
 
				+r.Queries("key", "value")
			
 
				+```
			
 
				+
			
 
				+...or to use a custom matcher function:
			
 
				+
			
 
				+```go
			
 
				+r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
			
 
				+    return r.ProtoMajor == 0
			
 
				+})
			
 
				+```
			
 
				+
			
 
				+...and finally, it is possible to combine several matchers in a single route:
			
 
				+
			
 
				+```go
			
 
				+r.HandleFunc("/products", ProductsHandler).
			
 
				+  Host("www.example.com").
			
 
				+  Methods("GET").
			
 
				+  Schemes("http")
			
 
				+```
			
 
				+
			
 
				+Routes are tested in the order they were added to the router. If two routes match, the first one wins:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+r.HandleFunc("/specific", specificHandler)
			
 
				+r.PathPrefix("/").Handler(catchAllHandler)
			
 
				+```
			
 
				+
			
 
				+Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting".
			
 
				+
			
 
				+For example, let's say we have several URLs that should only match when the host is `www.example.com`. Create a route for that host and get a "subrouter" from it:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+s := r.Host("www.example.com").Subrouter()
			
 
				+```
			
 
				+
			
 
				+Then register routes in the subrouter:
			
 
				+
			
 
				+```go
			
 
				+s.HandleFunc("/products/", ProductsHandler)
			
 
				+s.HandleFunc("/products/{key}", ProductHandler)
			
 
				+s.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
			
 
				+```
			
 
				+
			
 
				+The three URL paths we registered above will only be tested if the domain is `www.example.com`, because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route.
			
 
				+
			
 
				+Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter.
			
 
				+
			
 
				+There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+s := r.PathPrefix("/products").Subrouter()
			
 
				+// "/products/"
			
 
				+s.HandleFunc("/", ProductsHandler)
			
 
				+// "/products/{key}/"
			
 
				+s.HandleFunc("/{key}/", ProductHandler)
			
 
				+// "/products/{key}/details"
			
 
				+s.HandleFunc("/{key}/details", ProductDetailsHandler)
			
 
				+```
			
 
				+
			
 
				+
			
 
				+### Static Files
			
 
				+
			
 
				+Note that the path provided to `PathPrefix()` represents a "wildcard": calling
			
 
				+`PathPrefix("/static/").Handler(...)` means that the handler will be passed any
			
 
				+request that matches "/static/\*". This makes it easy to serve static files with mux:
			
 
				+
			
 
				+```go
			
 
				+func main() {
			
 
				+    var dir string
			
 
				+
			
 
				+    flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
			
 
				+    flag.Parse()
			
 
				+    r := mux.NewRouter()
			
 
				+
			
 
				+    // This will serve files under http://localhost:8000/static/<filename>
			
 
				+    r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
			
 
				+
			
 
				+    srv := &http.Server{
			
 
				+        Handler:      r,
			
 
				+        Addr:         "127.0.0.1:8000",
			
 
				+        // Good practice: enforce timeouts for servers you create!
			
 
				+        WriteTimeout: 15 * time.Second,
			
 
				+        ReadTimeout:  15 * time.Second,
			
 
				+    }
			
 
				+
			
 
				+    log.Fatal(srv.ListenAndServe())
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+### Registered URLs
			
 
				+
			
 
				+Now let's see how to build registered URLs.
			
 
				+
			
 
				+Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling `Name()` on a route. For example:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
			
 
				+  Name("article")
			
 
				+```
			
 
				+
			
 
				+To build a URL, get the route and call the `URL()` method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do:
			
 
				+
			
 
				+```go
			
 
				+url, err := r.Get("article").URL("category", "technology", "id", "42")
			
 
				+```
			
 
				+
			
 
				+...and the result will be a `url.URL` with the following path:
			
 
				+
			
 
				+```
			
 
				+"/articles/technology/42"
			
 
				+```
			
 
				+
			
 
				+This also works for host and query value variables:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+r.Host("{subdomain}.domain.com").
			
 
				+  Path("/articles/{category}/{id:[0-9]+}").
			
 
				+  Queries("filter", "{filter}").
			
 
				+  HandlerFunc(ArticleHandler).
			
 
				+  Name("article")
			
 
				+
			
 
				+// url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla"
			
 
				+url, err := r.Get("article").URL("subdomain", "news",
			
 
				+                                 "category", "technology",
			
 
				+                                 "id", "42",
			
 
				+                                 "filter", "gorilla")
			
 
				+```
			
 
				+
			
 
				+All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match.
			
 
				+
			
 
				+Regex support also exists for matching Headers within a route. For example, we could do:
			
 
				+
			
 
				+```go
			
 
				+r.HeadersRegexp("Content-Type", "application/(text|json)")
			
 
				+```
			
 
				+
			
 
				+...and the route will match both requests with a Content-Type of `application/json` as well as `application/text`
			
 
				+
			
 
				+There's also a way to build only the URL host or path for a route: use the methods `URLHost()` or `URLPath()` instead. For the previous route, we would do:
			
 
				+
			
 
				+```go
			
 
				+// "http://news.domain.com/"
			
 
				+host, err := r.Get("article").URLHost("subdomain", "news")
			
 
				+
			
 
				+// "/articles/technology/42"
			
 
				+path, err := r.Get("article").URLPath("category", "technology", "id", "42")
			
 
				+```
			
 
				+
			
 
				+And if you use subrouters, host and path defined separately can be built as well:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+s := r.Host("{subdomain}.domain.com").Subrouter()
			
 
				+s.Path("/articles/{category}/{id:[0-9]+}").
			
 
				+  HandlerFunc(ArticleHandler).
			
 
				+  Name("article")
			
 
				+
			
 
				+// "http://news.domain.com/articles/technology/42"
			
 
				+url, err := r.Get("article").URL("subdomain", "news",
			
 
				+                                 "category", "technology",
			
 
				+                                 "id", "42")
			
 
				+```
			
 
				+
			
 
				+### Walking Routes
			
 
				+
			
 
				+The `Walk` function on `mux.Router` can be used to visit all of the routes that are registered on a router. For example,
			
 
				+the following prints all of the registered routes:
			
 
				+
			
 
				+```go
			
 
				+package main
			
 
				+
			
 
				+import (
			
 
				+	"fmt"
			
 
				+	"net/http"
			
 
				+	"strings"
			
 
				+
			
 
				+	"github.com/gorilla/mux"
			
 
				+)
			
 
				+
			
 
				+func handler(w http.ResponseWriter, r *http.Request) {
			
 
				+	return
			
 
				+}
			
 
				+
			
 
				+func main() {
			
 
				+	r := mux.NewRouter()
			
 
				+	r.HandleFunc("/", handler)
			
 
				+	r.HandleFunc("/products", handler).Methods("POST")
			
 
				+	r.HandleFunc("/articles", handler).Methods("GET")
			
 
				+	r.HandleFunc("/articles/{id}", handler).Methods("GET", "PUT")
			
 
				+	r.HandleFunc("/authors", handler).Queries("surname", "{surname}")
			
 
				+	err := r.Walk(func(route *mux.Route, router *mux.Router, ancestors []*mux.Route) error {
			
 
				+		pathTemplate, err := route.GetPathTemplate()
			
 
				+		if err == nil {
			
 
				+			fmt.Println("ROUTE:", pathTemplate)
			
 
				+		}
			
 
				+		pathRegexp, err := route.GetPathRegexp()
			
 
				+		if err == nil {
			
 
				+			fmt.Println("Path regexp:", pathRegexp)
			
 
				+		}
			
 
				+		queriesTemplates, err := route.GetQueriesTemplates()
			
 
				+		if err == nil {
			
 
				+			fmt.Println("Queries templates:", strings.Join(queriesTemplates, ","))
			
 
				+		}
			
 
				+		queriesRegexps, err := route.GetQueriesRegexp()
			
 
				+		if err == nil {
			
 
				+			fmt.Println("Queries regexps:", strings.Join(queriesRegexps, ","))
			
 
				+		}
			
 
				+		methods, err := route.GetMethods()
			
 
				+		if err == nil {
			
 
				+			fmt.Println("Methods:", strings.Join(methods, ","))
			
 
				+		}
			
 
				+		fmt.Println()
			
 
				+		return nil
			
 
				+	})
			
 
				+
			
 
				+	if err != nil {
			
 
				+		fmt.Println(err)
			
 
				+	}
			
 
				+
			
 
				+	http.Handle("/", r)
			
 
				+}
			
 
				+```

				+### Graceful Shutdown
			
 
				+
			
 
				+Go 1.8 introduced the ability to [gracefully shutdown](https://golang.org/doc/go1.8#http_shutdown) a `*http.Server`. Here's how to do that alongside `mux`:
			
 
				+
			
 
				+```go
			
 
				+package main
			
 
				+
			
 
				+import (
			
 
				+    "context"
			
 
				+    "flag"
			
 
				+    "log"
			
 
				+    "net/http"
			
 
				+    "os"
			
 
				+    "os/signal"
			
 
				+    "time"
			
 
				+
			
 
				+    "github.com/gorilla/mux"
			
 
				+)
			
 
				+
			
 
				+func main() {
			
 
				+    var wait time.Duration
			
 
				+    flag.DurationVar(&wait, "graceful-timeout", time.Second * 15, "the duration for which the server gracefully wait for existing connections to finish - e.g. 15s or 1m")
			
 
				+    flag.Parse()
			
 
				+
			
 
				+    r := mux.NewRouter()
			
 
				+    // Add your routes as needed
			
 
				+
			
 
				+    srv := &http.Server{
			
 
				+        Addr:         "0.0.0.0:8080",
			
 
				+        // Good practice to set timeouts to avoid Slowloris attacks.
			
 
				+        WriteTimeout: time.Second * 15,
			
 
				+        ReadTimeout:  time.Second * 15,
			
 
				+        IdleTimeout:  time.Second * 60,
			
 
				+        Handler: r, // Pass our instance of gorilla/mux in.
			
 
				+    }
			
 
				+
			
 
				+    // Run our server in a goroutine so that it doesn't block.
			
 
				+    go func() {
			
 
				+        if err := srv.ListenAndServe(); err != nil {
			
 
				+            log.Println(err)
			
 
				+        }
			
 
				+    }()
			
 
				+
			
 
				+    c := make(chan os.Signal, 1)
			
 
				+    // We'll accept graceful shutdowns when quit via SIGINT (Ctrl+C)
			
 
				+    // SIGKILL, SIGQUIT or SIGTERM (Ctrl+/) will not be caught.
			
 
				+    signal.Notify(c, os.Interrupt)
			
 
				+
			
 
				+    // Block until we receive our signal.
			
 
				+    <-c
			
 
				+
			
 
				+    // Create a deadline to wait for.
			
 
				+    ctx, cancel := context.WithTimeout(context.Background(), wait)
			
 
				+    defer cancel()
			
 
				+    // Doesn't block if no connections, but will otherwise wait
			
 
				+    // until the timeout deadline.
			
 
				+    srv.Shutdown(ctx)
			
 
				+    // Optionally, you could run srv.Shutdown in a goroutine and block on
			
 
				+    // <-ctx.Done() if your application should wait for other services
			
 
				+    // to finalize based on context cancellation.
			
 
				+    log.Println("shutting down")
			
 
				+    os.Exit(0)
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+### Middleware
			
 
				+
			
 
				+Mux supports the addition of middlewares to a [Router](https://godoc.org/github.com/gorilla/mux#Router), which are executed in the order they are added if a match is found, including its subrouters.
			
 
				+Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or `ResponseWriter` hijacking.
			
 
				+
			
 
				+Mux middlewares are defined using the de facto standard type:
			
 
				+
			
 
				+```go
			
 
				+type MiddlewareFunc func(http.Handler) http.Handler
			
 
				+```
			
 
				+
			
 
				+Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc. This takes advantage of closures being able access variables from the context where they are created, while retaining the signature enforced by the receivers.
			
 
				+
			
 
				+A very basic middleware which logs the URI of the request being handled could be written as:
			
 
				+
			
 
				+```go
			
 
				+func loggingMiddleware(next http.Handler) http.Handler {
			
 
				+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
			
 
				+        // Do stuff here
			
 
				+        log.Println(r.RequestURI)
			
 
				+        // Call the next handler, which can be another middleware in the chain, or the final handler.
			
 
				+        next.ServeHTTP(w, r)
			
 
				+    })
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+Middlewares can be added to a router using `Router.Use()`:
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+r.HandleFunc("/", handler)
			
 
				+r.Use(loggingMiddleware)
			
 
				+```
			
 
				+
			
 
				+A more complex authentication middleware, which maps session token to users, could be written as:
			
 
				+
			
 
				+```go
			
 
				+// Define our struct
			
 
				+type authenticationMiddleware struct {
			
 
				+	tokenUsers map[string]string
			
 
				+}
			
 
				+
			
 
				+// Initialize it somewhere
			
 
				+func (amw *authenticationMiddleware) Populate() {
			
 
				+	amw.tokenUsers["00000000"] = "user0"
			
 
				+	amw.tokenUsers["aaaaaaaa"] = "userA"
			
 
				+	amw.tokenUsers["05f717e5"] = "randomUser"
			
 
				+	amw.tokenUsers["deadbeef"] = "user0"
			
 
				+}
			
 
				+
			
 
				+// Middleware function, which will be called for each request
			
 
				+func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
			
 
				+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
			
 
				+        token := r.Header.Get("X-Session-Token")
			
 
				+
			
 
				+        if user, found := amw.tokenUsers[token]; found {
			
 
				+        	// We found the token in our map
			
 
				+        	log.Printf("Authenticated user %s\n", user)
			
 
				+        	// Pass down the request to the next middleware (or final handler)
			
 
				+        	next.ServeHTTP(w, r)
			
 
				+        } else {
			
 
				+        	// Write an error and stop the handler chain
			
 
				+        	http.Error(w, "Forbidden", http.StatusForbidden)
			
 
				+        }
			
 
				+    })
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+```go
			
 
				+r := mux.NewRouter()
			
 
				+r.HandleFunc("/", handler)
			
 
				+
			
 
				+amw := authenticationMiddleware{}
			
 
				+amw.Populate()
			
 
				+
			
 
				+r.Use(amw.Middleware)
			
 
				+```
			
 
				+
			
 
				+Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to. Middlewares _should_ write to `ResponseWriter` if they _are_ going to terminate the request, and they _should not_ write to `ResponseWriter` if they _are not_ going to terminate it.
			
 
				+
			
 
				+### Testing Handlers
			
 
				+
			
 
				+Testing handlers in a Go web application is straightforward, and _mux_ doesn't complicate this any further. Given two files: `endpoints.go` and `endpoints_test.go`, here's how we'd test an application using _mux_.
			
 
				+
			
 
				+First, our simple HTTP handler:
			
 
				+
			
 
				+```go
			
 
				+// endpoints.go
			
 
				+package main
			
 
				+
			
 
				+func HealthCheckHandler(w http.ResponseWriter, r *http.Request) {
			
 
				+    // A very simple health check.
			
 
				+    w.WriteHeader(http.StatusOK)
			
 
				+    w.Header().Set("Content-Type", "application/json")
			
 
				+
			
 
				+    // In the future we could report back on the status of our DB, or our cache
			
 
				+    // (e.g. Redis) by performing a simple PING, and include them in the response.
			
 
				+    io.WriteString(w, `{"alive": true}`)
			
 
				+}
			
 
				+
			
 
				+func main() {
			
 
				+    r := mux.NewRouter()
			
 
				+    r.HandleFunc("/health", HealthCheckHandler)
			
 
				+
			
 
				+    log.Fatal(http.ListenAndServe("localhost:8080", r))
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+Our test code:
			
 
				+
			
 
				+```go
			
 
				+// endpoints_test.go
			
 
				+package main
			
 
				+
			
 
				+import (
			
 
				+    "net/http"
			
 
				+    "net/http/httptest"
			
 
				+    "testing"
			
 
				+)
			
 
				+
			
 
				+func TestHealthCheckHandler(t *testing.T) {
			
 
				+    // Create a request to pass to our handler. We don't have any query parameters for now, so we'll
			
 
				+    // pass 'nil' as the third parameter.
			
 
				+    req, err := http.NewRequest("GET", "/health", nil)
			
 
				+    if err != nil {
			
 
				+        t.Fatal(err)
			
 
				+    }
			
 
				+
			
 
				+    // We create a ResponseRecorder (which satisfies http.ResponseWriter) to record the response.
			
 
				+    rr := httptest.NewRecorder()
			
 
				+    handler := http.HandlerFunc(HealthCheckHandler)
			
 
				+
			
 
				+    // Our handlers satisfy http.Handler, so we can call their ServeHTTP method
			
 
				+    // directly and pass in our Request and ResponseRecorder.
			
 
				+    handler.ServeHTTP(rr, req)
			
 
				+
			
 
				+    // Check the status code is what we expect.
			
 
				+    if status := rr.Code; status != http.StatusOK {
			
 
				+        t.Errorf("handler returned wrong status code: got %v want %v",
			
 
				+            status, http.StatusOK)
			
 
				+    }
			
 
				+
			
 
				+    // Check the response body is what we expect.
			
 
				+    expected := `{"alive": true}`
			
 
				+    if rr.Body.String() != expected {
			
 
				+        t.Errorf("handler returned unexpected body: got %v want %v",
			
 
				+            rr.Body.String(), expected)
			
 
				+    }
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+In the case that our routes have [variables](#examples), we can pass those in the request. We could write
			
 
				+[table-driven tests](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go) to test multiple
			
 
				+possible route variables as needed.
			
 
				+
			
 
				+```go
			
 
				+// endpoints.go
			
 
				+func main() {
			
 
				+    r := mux.NewRouter()
			
 
				+    // A route with a route variable:
			
 
				+    r.HandleFunc("/metrics/{type}", MetricsHandler)
			
 
				+
			
 
				+    log.Fatal(http.ListenAndServe("localhost:8080", r))
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+Our test file, with a table-driven test of `routeVariables`:
			
 
				+
			
 
				+```go
			
 
				+// endpoints_test.go
			
 
				+func TestMetricsHandler(t *testing.T) {
			
 
				+    tt := []struct{
			
 
				+        routeVariable string
			
 
				+        shouldPass bool
			
 
				+    }{
			
 
				+        {"goroutines", true},
			
 
				+        {"heap", true},
			
 
				+        {"counters", true},
			
 
				+        {"queries", true},
			
 
				+        {"adhadaeqm3k", false},
			
 
				+    }
			
 
				+
			
 
				+    for _, tc := range tt {
			
 
				+        path := fmt.Sprintf("/metrics/%s", tc.routeVariable)
			
 
				+        req, err := http.NewRequest("GET", path, nil)
			
 
				+        if err != nil {
			
 
				+            t.Fatal(err)
			
 
				+        }
			
 
				+
			
 
				+        rr := httptest.NewRecorder()
			
 
				+	
			
 
				+	// Need to create a router that we can pass the request through so that the vars will be added to the context
			
 
				+	router := mux.NewRouter()
			
 
				+        router.HandleFunc("/metrics/{type}", MetricsHandler)
			
 
				+        router.ServeHTTP(rr, req)
			
 
				+
			
 
				+        // In this case, our MetricsHandler returns a non-200 response
			
 
				+        // for a route variable it doesn't know about.
			
 
				+        if rr.Code == http.StatusOK && !tc.shouldPass {
			
 
				+            t.Errorf("handler should have failed on routeVariable %s: got %v want %v",
			
 
				+                tc.routeVariable, rr.Code, http.StatusOK)
			
 
				+        }
			
 
				+    }
			
 
				+}
			
 
				+```
			
 
				+
			
 
				+## Full Example
			
 
				+
			
 
				+Here's a complete, runnable example of a small `mux` based server:
			
 
				+
			
 
				+```go
			
 
				+package main
			
 
				+
			
 
				+import (
			
 
				+    "net/http"
			
 
				+    "log"
			
 
				+    "github.com/gorilla/mux"
			
 
				+)
			
 
				+
			
 
				+func YourHandler(w http.ResponseWriter, r *http.Request) {
			
 
				+    w.Write([]byte("Gorilla!\n"))
			
 
				+}
			
 
				+
			
 
				+func main() {
			
 
				+    r := mux.NewRouter()
			
 
				+    // Routes consist of a path and a handler function.
			
 
				+    r.HandleFunc("/", YourHandler)
			
 
				+
			
 
				+    // Bind to a port and pass our router in
			
 
				+    log.Fatal(http.ListenAndServe(":8000", r))
			
 
				+}
			
 
				+```

				+/*
			
 
				+Package mux implements a request router and dispatcher.
			
 
				+
			
 
				+The name mux stands for "HTTP request multiplexer". Like the standard
			
 
				+http.ServeMux, mux.Router matches incoming requests against a list of
			
 
				+registered routes and calls a handler for the route that matches the URL
			
 
				+or other conditions. The main features are:
			
 
				+
			
 
				+	* Requests can be matched based on URL host, path, path prefix, schemes,
			
 
				+	  header and query values, HTTP methods or using custom matchers.
			
 
				+	* URL hosts, paths and query values can have variables with an optional
			
 
				+	  regular expression.
			
 
				+	* Registered URLs can be built, or "reversed", which helps maintaining
			
 
				+	  references to resources.
			
 
				+	* Routes can be used as subrouters: nested routes are only tested if the
			
 
				+	  parent route matches. This is useful to define groups of routes that
			
 
				+	  share common conditions like a host, a path prefix or other repeated
			
 
				+	  attributes. As a bonus, this optimizes request matching.
			
 
				+	* It implements the http.Handler interface so it is compatible with the
			
 
				+	  standard http.ServeMux.
			
 
				+
			
 
				+Let's start registering a couple of URL paths and handlers:
			
 
				+
			
 
				+	func main() {
			
 
				+		r := mux.NewRouter()
			
 
				+		r.HandleFunc("/", HomeHandler)
			
 
				+		r.HandleFunc("/products", ProductsHandler)
			
 
				+		r.HandleFunc("/articles", ArticlesHandler)
			
 
				+		http.Handle("/", r)
			
 
				+	}
			
 
				+
			
 
				+Here we register three routes mapping URL paths to handlers. This is
			
 
				+equivalent to how http.HandleFunc() works: if an incoming request URL matches
			
 
				+one of the paths, the corresponding handler is called passing
			
 
				+(http.ResponseWriter, *http.Request) as parameters.
			
 
				+
			
 
				+Paths can have variables. They are defined using the format {name} or
			
 
				+{name:pattern}. If a regular expression pattern is not defined, the matched
			
 
				+variable will be anything until the next slash. For example:
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	r.HandleFunc("/products/{key}", ProductHandler)
			
 
				+	r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
			
 
				+	r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
			
 
				+
			
 
				+Groups can be used inside patterns, as long as they are non-capturing (?:re). For example:
			
 
				+
			
 
				+	r.HandleFunc("/articles/{category}/{sort:(?:asc|desc|new)}", ArticlesCategoryHandler)
			
 
				+
			
 
				+The names are used to create a map of route variables which can be retrieved
			
 
				+calling mux.Vars():
			
 
				+
			
 
				+	vars := mux.Vars(request)
			
 
				+	category := vars["category"]
			
 
				+
			
 
				+Note that if any capturing groups are present, mux will panic() during parsing. To prevent
			
 
				+this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to
			
 
				+"/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably
			
 
				+when capturing groups were present.
			
 
				+
			
 
				+And this is all you need to know about the basic usage. More advanced options
			
 
				+are explained below.
			
 
				+
			
 
				+Routes can also be restricted to a domain or subdomain. Just define a host
			
 
				+pattern to be matched. They can also have variables:
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	// Only matches if domain is "www.example.com".
			
 
				+	r.Host("www.example.com")
			
 
				+	// Matches a dynamic subdomain.
			
 
				+	r.Host("{subdomain:[a-z]+}.domain.com")
			
 
				+
			
 
				+There are several other matchers that can be added. To match path prefixes:
			
 
				+
			
 
				+	r.PathPrefix("/products/")
			
 
				+
			
 
				+...or HTTP methods:
			
 
				+
			
 
				+	r.Methods("GET", "POST")
			
 
				+
			
 
				+...or URL schemes:
			
 
				+
			
 
				+	r.Schemes("https")
			
 
				+
			
 
				+...or header values:
			
 
				+
			
 
				+	r.Headers("X-Requested-With", "XMLHttpRequest")
			
 
				+
			
 
				+...or query values:
			
 
				+
			
 
				+	r.Queries("key", "value")
			
 
				+
			
 
				+...or to use a custom matcher function:
			
 
				+
			
 
				+	r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
			
 
				+		return r.ProtoMajor == 0
			
 
				+	})
			
 
				+
			
 
				+...and finally, it is possible to combine several matchers in a single route:
			
 
				+
			
 
				+	r.HandleFunc("/products", ProductsHandler).
			
 
				+	  Host("www.example.com").
			
 
				+	  Methods("GET").
			
 
				+	  Schemes("http")

				+Setting the same matching conditions again and again can be boring, so we have
			
 
				+a way to group several routes that share the same requirements.
			
 
				+We call it "subrouting".
			
 
				+
			
 
				+For example, let's say we have several URLs that should only match when the
			
 
				+host is "www.example.com". Create a route for that host and get a "subrouter"
			
 
				+from it:
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	s := r.Host("www.example.com").Subrouter()
			
 
				+
			
 
				+Then register routes in the subrouter:
			
 
				+
			
 
				+	s.HandleFunc("/products/", ProductsHandler)
			
 
				+	s.HandleFunc("/products/{key}", ProductHandler)
			
 
				+	s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler)
			
 
				+
			
 
				+The three URL paths we registered above will only be tested if the domain is
			
 
				+"www.example.com", because the subrouter is tested first. This is not
			
 
				+only convenient, but also optimizes request matching. You can create
			
 
				+subrouters combining any attribute matchers accepted by a route.
			
 
				+
			
 
				+Subrouters can be used to create domain or path "namespaces": you define
			
 
				+subrouters in a central place and then parts of the app can register its
			
 
				+paths relatively to a given subrouter.
			
 
				+
			
 
				+There's one more thing about subroutes. When a subrouter has a path prefix,
			
 
				+the inner routes use it as base for their paths:
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	s := r.PathPrefix("/products").Subrouter()
			
 
				+	// "/products/"
			
 
				+	s.HandleFunc("/", ProductsHandler)
			
 
				+	// "/products/{key}/"
			
 
				+	s.HandleFunc("/{key}/", ProductHandler)
			
 
				+	// "/products/{key}/details"
			
 
				+	s.HandleFunc("/{key}/details", ProductDetailsHandler)
			
 
				+
			
 
				+Note that the path provided to PathPrefix() represents a "wildcard": calling
			
 
				+PathPrefix("/static/").Handler(...) means that the handler will be passed any
			
 
				+request that matches "/static/*". This makes it easy to serve static files with mux:
			
 
				+
			
 
				+	func main() {
			
 
				+		var dir string
			
 
				+
			
 
				+		flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
			
 
				+		flag.Parse()
			
 
				+		r := mux.NewRouter()
			
 
				+
			
 
				+		// This will serve files under http://localhost:8000/static/<filename>
			
 
				+		r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
			
 
				+
			
 
				+		srv := &http.Server{
			
 
				+			Handler:      r,
			
 
				+			Addr:         "127.0.0.1:8000",
			
 
				+			// Good practice: enforce timeouts for servers you create!
			
 
				+			WriteTimeout: 15 * time.Second,
			
 
				+			ReadTimeout:  15 * time.Second,
			
 
				+		}
			
 
				+
			
 
				+		log.Fatal(srv.ListenAndServe())
			
 
				+	}
			
 
				+
			
 
				+Now let's see how to build registered URLs.
			
 
				+
			
 
				+Routes can be named. All routes that define a name can have their URLs built,
			
 
				+or "reversed". We define a name calling Name() on a route. For example:
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
			
 
				+	  Name("article")
			
 
				+
			
 
				+To build a URL, get the route and call the URL() method, passing a sequence of
			
 
				+key/value pairs for the route variables. For the previous route, we would do:
			
 
				+
			
 
				+	url, err := r.Get("article").URL("category", "technology", "id", "42")
			
 
				+
			
 
				+...and the result will be a url.URL with the following path:
			
 
				+
			
 
				+	"/articles/technology/42"
			
 
				+
			
 
				+This also works for host and query value variables:
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	r.Host("{subdomain}.domain.com").
			
 
				+	  Path("/articles/{category}/{id:[0-9]+}").
			
 
				+	  Queries("filter", "{filter}").
			
 
				+	  HandlerFunc(ArticleHandler).
			
 
				+	  Name("article")
			
 
				+
			
 
				+	// url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla"
			
 
				+	url, err := r.Get("article").URL("subdomain", "news",
			
 
				+	                                 "category", "technology",
			
 
				+	                                 "id", "42",
			
 
				+	                                 "filter", "gorilla")
			
 
				+
			
 
				+All variables defined in the route are required, and their values must
			
 
				+conform to the corresponding patterns. These requirements guarantee that a
			
 
				+generated URL will always match a registered route -- the only exception is
			
 
				+for explicitly defined "build-only" routes which never match.
			
 
				+
			
 
				+Regex support also exists for matching Headers within a route. For example, we could do:
			
 
				+
			
 
				+	r.HeadersRegexp("Content-Type", "application/(text|json)")
			
 
				+
			
 
				+...and the route will match both requests with a Content-Type of `application/json` as well as
			
 
				+`application/text`
			
 
				+
			
 
				+There's also a way to build only the URL host or path for a route:
			
 
				+use the methods URLHost() or URLPath() instead. For the previous route,
			
 
				+we would do:
			
 
				+
			
 
				+	// "http://news.domain.com/"
			
 
				+	host, err := r.Get("article").URLHost("subdomain", "news")
			
 
				+
			
 
				+	// "/articles/technology/42"
			
 
				+	path, err := r.Get("article").URLPath("category", "technology", "id", "42")
			
 
				+
			
 
				+And if you use subrouters, host and path defined separately can be built
			
 
				+as well:
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	s := r.Host("{subdomain}.domain.com").Subrouter()
			
 
				+	s.Path("/articles/{category}/{id:[0-9]+}").
			
 
				+	  HandlerFunc(ArticleHandler).
			
 
				+	  Name("article")
			
 
				+
			
 
				+	// "http://news.domain.com/articles/technology/42"
			
 
				+	url, err := r.Get("article").URL("subdomain", "news",
			
 
				+	                                 "category", "technology",
			
 
				+	                                 "id", "42")
			
 
				+
			
 
				+Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking.
			
 
				+
			
 
				+	type MiddlewareFunc func(http.Handler) http.Handler
			
 
				+
			
 
				+Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created).
			
 
				+
			
 
				+A very basic middleware which logs the URI of the request being handled could be written as:
			
 
				+
			
 
				+	func simpleMw(next http.Handler) http.Handler {
			
 
				+		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
			
 
				+			// Do stuff here
			
 
				+			log.Println(r.RequestURI)
			
 
				+			// Call the next handler, which can be another middleware in the chain, or the final handler.
			
 
				+			next.ServeHTTP(w, r)
			
 
				+		})
			
 
				+	}
			
 
				+
			
 
				+Middlewares can be added to a router using `Router.Use()`:
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	r.HandleFunc("/", handler)
			
 
				+	r.Use(simpleMw)
			
 
				+
			
 
				+A more complex authentication middleware, which maps session token to users, could be written as:
			
 
				+
			
 
				+	// Define our struct
			
 
				+	type authenticationMiddleware struct {
			
 
				+		tokenUsers map[string]string
			
 
				+	}
			
 
				+
			
 
				+	// Initialize it somewhere
			
 
				+	func (amw *authenticationMiddleware) Populate() {
			
 
				+		amw.tokenUsers["00000000"] = "user0"
			
 
				+		amw.tokenUsers["aaaaaaaa"] = "userA"
			
 
				+		amw.tokenUsers["05f717e5"] = "randomUser"
			
 
				+		amw.tokenUsers["deadbeef"] = "user0"
			
 
				+	}
			
 
				+
			
 
				+	// Middleware function, which will be called for each request
			
 
				+	func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
			
 
				+		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
			
 
				+			token := r.Header.Get("X-Session-Token")
			
 
				+
			
 
				+			if user, found := amw.tokenUsers[token]; found {
			
 
				+				// We found the token in our map
			
 
				+				log.Printf("Authenticated user %s\n", user)
			
 
				+				next.ServeHTTP(w, r)
			
 
				+			} else {
			
 
				+				http.Error(w, "Forbidden", http.StatusForbidden)
			
 
				+			}
			
 
				+		})
			
 
				+	}
			
 
				+
			
 
				+	r := mux.NewRouter()
			
 
				+	r.HandleFunc("/", handler)
			
 
				+
			
 
				+	amw := authenticationMiddleware{}
			
 
				+	amw.Populate()
			
 
				+
			
 
				+	r.Use(amw.Middleware)
			
 
				+
			
 
				+Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

				-
			
 
				-HttpRouter is a lightweight high performance HTTP request router
			
 
				-(also called *multiplexer* or just *mux* for short) for [Go](http://golang.org/).
			
 
				-
			
 
				-In contrast to the [default mux](http://golang.org/pkg/net/http/#ServeMux) of Go's net/http package, this router supports
			
 
				-variables in the routing pattern and matches against the request method.
			
 
				-It also scales better.
			
 
				-
			
 
				-The router is optimized for high performance and a small memory footprint.
			
 
				-It scales well even with very long paths and a large number of routes.
			
 
				-A compressing dynamic trie (radix tree) structure is used for efficient matching.
			
 
				-
			
 
				-## Features
			
 
				-**Only explicit matches:** With other routers, like [http.ServeMux](http://golang.org/pkg/net/http/#ServeMux),
			
 
				-a requested URL path could match multiple patterns. Therefore they have some
			
 
				-awkward pattern priority rules, like *longest match* or *first registered,
			
 
				-first matched*. By design of this router, a request can only match exactly one
			
 
				-or no route. As a result, there are also no unintended matches, which makes it
			
 
				-great for SEO and improves the user experience.
			
 
				-
			
 
				-**Stop caring about trailing slashes:** Choose the URL style you like, the
			
 
				-router automatically redirects the client if a trailing slash is missing or if
			
 
				-there is one extra. Of course it only does so, if the new path has a handler.
			
 
				-If you don't like it, you can [turn off this behavior](http://godoc.org/github.com/julienschmidt/httprouter#Router.RedirectTrailingSlash).
			
 
				-
			
 
				-**Path auto-correction:** Besides detecting the missing or additional trailing
			
 
				-slash at no extra cost, the router can also fix wrong cases and remove
			
 
				-superfluous path elements (like `../` or `//`).
			
 
				-Is [CAPTAIN CAPS LOCK](http://www.urbandictionary.com/define.php?term=Captain+Caps+Lock) one of your users?
			
 
				-HttpRouter can help him by making a case-insensitive look-up and redirecting him
			
 
				-to the correct URL.
			
 
				-
			
 
				-**Parameters in your routing pattern:** Stop parsing the requested URL path,
			
 
				-just give the path segment a name and the router delivers the dynamic value to
			
 
				-you. Because of the design of the router, path parameters are very cheap.
			
 
				-
			
 
				-**Zero Garbage:** The matching and dispatching process generates zero bytes of
			
 
				-garbage. In fact, the only heap allocations that are made, is by building the
			
 
				-slice of the key-value pairs for path parameters. If the request path contains
			
 
				-no parameters, not a single heap allocation is necessary.
			
 
				-
			
 
				-**Best Performance:** [Benchmarks speak for themselves](https://github.com/julienschmidt/go-http-routing-benchmark).
			
 
				-See below for technical details of the implementation.
			
 
				-
			
 
				-**No more server crashes:** You can set a [Panic handler](http://godoc.org/github.com/julienschmidt/httprouter#Router.PanicHandler) to deal with panics
			
 
				-occurring during handling a HTTP request. The router then recovers and lets the
			
 
				-PanicHandler log what happened and deliver a nice error page.
			
 
				-
			
 
				-Of course you can also set **custom [NotFound](http://godoc.org/github.com/julienschmidt/httprouter#Router.NotFound) and  [MethodNotAllowed](http://godoc.org/github.com/julienschmidt/httprouter#Router.MethodNotAllowed) handlers** and [**serve static files**](http://godoc.org/github.com/julienschmidt/httprouter#Router.ServeFiles).
			
 
				-
			
 
				-## Usage
			
 
				-This is just a quick introduction, view the [GoDoc](http://godoc.org/github.com/julienschmidt/httprouter) for details.
			
 
				-
			
 
				-Let's start with a trivial example:
			
 
				-```go
			
 
				-package main
			
 
				-
			
 
				-import (
			
 
				-    "fmt"
			
 
				-    "github.com/julienschmidt/httprouter"
			
 
				-    "net/http"
			
 
				-    "log"
			
 
				-)
			
 
				-
			
 
				-func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
			
 
				-    fmt.Fprint(w, "Welcome!\n")
			
 
				-}
			
 
				-
			
 
				-func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
			
 
				-    fmt.Fprintf(w, "hello, %s!\n", ps.ByName("name"))
			
 
				-}
			
 
				-
			
 
				-func main() {
			
 
				-    router := httprouter.New()
			
 
				-    router.GET("/", Index)
			
 
				-    router.GET("/hello/:name", Hello)
			
 
				-
			
 
				-    log.Fatal(http.ListenAndServe(":8080", router))
			
 
				-}
			
 
				-```
			
 
				-
			
 
				-### Named parameters
			
 
				-As you can see, `:name` is a *named parameter*.
			
 
				-The values are accessible via `httprouter.Params`, which is just a slice of `httprouter.Param`s.
			
 
				-You can get the value of a parameter either by its index in the slice, or by using the `ByName(name)` method:
			
 
				-`:name` can be retrived by `ByName("name")`.
			
 
				-
			
 
				-Named parameters only match a single path segment:
			
 
				-```
			
 
				-Pattern: /user/:user
			
 
				-
			
 
				- /user/gordon              match
			
 
				- /user/you                 match
			
 
				- /user/gordon/profile      no match
			
 
				- /user/                    no match
			
 
				-```
			
 
				-
			
 
				-**Note:** Since this router has only explicit matches, you can not register static routes and parameters for the same path segment. For example you can not register the patterns `/user/new` and `/user/:user` for the same request method at the same time. The routing of different request methods is independent from each other.
			
 
				-
			
 
				-### Catch-All parameters
			
 
				-The second type are *catch-all* parameters and have the form `*name`.
			
 
				-Like the name suggests, they match everything.
			
 
				-Therefore they must always be at the **end** of the pattern:
			
 
				-```
			
 
				-Pattern: /src/*filepath
			
 
				-
			
 
				- /src/                     match
			
 
				- /src/somefile.go          match
			
 
				- /src/subdir/somefile.go   match
			
 
				-```
			
 
				-
			
 
				-## How does it work?
			
 
				-The router relies on a tree structure which makes heavy use of *common prefixes*,
			
 
				-it is basically a *compact* [*prefix tree*](http://en.wikipedia.org/wiki/Trie)
			
 
				-(or just [*Radix tree*](http://en.wikipedia.org/wiki/Radix_tree)).
			
 
				-Nodes with a common prefix also share a common parent. Here is a short example
			
 
				-what the routing tree for the `GET` request method could look like:
			
 
				-
			
 
				-```
			
 
				-Priority   Path             Handle
			
 
				-9          \                *<1>
			
 
				-3          ├s               nil
			
 
				-2          |├earch\         *<2>
			
 
				-1          |└upport\        *<3>
			
 
				-2          ├blog\           *<4>
			
 
				-1          |    └:post      nil
			
 
				-1          |         └\     *<5>
			
 
				-2          ├about-us\       *<6>
			
 
				-1          |        └team\  *<7>
			
 
				-1          └contact\        *<8>
			
 
				-```
			
 
				-Every `*<num>` represents the memory address of a handler function (a pointer).
			
 
				-If you follow a path trough the tree from the root to the leaf, you get the
			
 
				-complete route path, e.g `\blog\:post\`, where `:post` is just a placeholder
			
 
				-([*parameter*](#named-parameters)) for an actual post name. Unlike hash-maps, a
			
 
				-tree structure also allows us to use dynamic parts like the `:post` parameter,
			
 
				-since we actually match against the routing patterns instead of just comparing
			
 
				-hashes. [As benchmarks show](https://github.com/julienschmidt/go-http-routing-benchmark),
			
 
				-this works very well and efficient.
			
 
				-
			
 
				-Since URL paths have a hierarchical structure and make use only of a limited set
			
 
				-of characters (byte values), it is very likely that there are a lot of common
			
 
				-prefixes. This allows us to easily reduce the routing into ever smaller problems.
			
 
				-Moreover the router manages a separate tree for every request method.
			
 
				-For one thing it is more space efficient than holding a method->handle map in
			
 
				-every single node, for another thing is also allows us to greatly reduce the
			
 
				-routing problem before even starting the look-up in the prefix-tree.
			
 
				-
			
 
				-For even better scalability, the child nodes on each tree level are ordered by
			
 
				-priority, where the priority is just the number of handles registered in sub
			
 
				-nodes (children, grandchildren, and so on..).
			
 
				-This helps in two ways:
			
 
				-
			
 
				-1. Nodes which are part of the most routing paths are evaluated first. This
			
 
				-helps to make as much routes as possible to be reachable as fast as possible.
			
 
				-2. It is some sort of cost compensation. The longest reachable path (highest
			
 
				-cost) can always be evaluated first. The following scheme visualizes the tree
			
 
				-structure. Nodes are evaluated from top to bottom and from left to right.

				-## Why doesn't this work with http.Handler?
			
 
				-**It does!** The router itself implements the http.Handler interface.
			
 
				-Moreover the router provides convenient [adapters for http.Handler](http://godoc.org/github.com/julienschmidt/httprouter#Router.Handler)s and [http.HandlerFunc](http://godoc.org/github.com/julienschmidt/httprouter#Router.HandlerFunc)s
			
 
				-which allows them to be used as a [httprouter.Handle](http://godoc.org/github.com/julienschmidt/httprouter#Router.Handle) when registering a route.
			
 
				-The only disadvantage is, that no parameter values can be retrieved when a
			
 
				-http.Handler or http.HandlerFunc is used, since there is no efficient way to
			
 
				-pass the values with the existing function parameters.
			
 
				-Therefore [httprouter.Handle](http://godoc.org/github.com/julienschmidt/httprouter#Router.Handle) has a third function parameter.
			
 
				-
			
 
				-Just try it out for yourself, the usage of HttpRouter is very straightforward. The package is compact and minimalistic, but also probably one of the easiest routers to set up.
			
 
				-
			
 
				-
			
 
				-## Where can I find Middleware *X*?
			
 
				-This package just provides a very efficient request router with a few extra
			
 
				-features. The router is just a [http.Handler](http://golang.org/pkg/net/http/#Handler),
			
 
				-you can chain any http.Handler compatible middleware before the router,
			
 
				-for example the [Gorilla handlers](http://www.gorillatoolkit.org/pkg/handlers).
			
 
				-Or you could [just write your own](http://justinas.org/writing-http-middleware-in-go/),
			
 
				-it's very easy!
			
 
				-
			
 
				-Alternatively, you could try [a web framework based on HttpRouter](#web-frameworks-based-on-httprouter).
			
 
				-
			
 
				-### Multi-domain / Sub-domains
			
 
				-Here is a quick example: Does your server serve multiple domains / hosts?
			
 
				-You want to use sub-domains?
			
 
				-Define a router per host!
			
 
				-```go
			
 
				-// We need an object that implements the http.Handler interface.
			
 
				-// Therefore we need a type for which we implement the ServeHTTP method.
			
 
				-// We just use a map here, in which we map host names (with port) to http.Handlers
			
 
				-type HostSwitch map[string]http.Handler
			
 
				-
			
 
				-// Implement the ServerHTTP method on our new type
			
 
				-func (hs HostSwitch) ServeHTTP(w http.ResponseWriter, r *http.Request) {
			
 
				-	// Check if a http.Handler is registered for the given host.
			
 
				-	// If yes, use it to handle the request.
			
 
				-	if handler := hs[r.Host]; handler != nil {
			
 
				-		handler.ServeHTTP(w, r)
			
 
				-	} else {
			
 
				-		// Handle host names for wich no handler is registered
			
 
				-		http.Error(w, "Forbidden", 403) // Or Redirect?
			
 
				-	}
			
 
				-}
			
 
				-
			
 
				-func main() {
			
 
				-	// Initialize a router as usual
			
 
				-	router := httprouter.New()
			
 
				-	router.GET("/", Index)
			
 
				-	router.GET("/hello/:name", Hello)
			
 
				-
			
 
				-	// Make a new HostSwitch and insert the router (our http handler)
			
 
				-	// for example.com and port 12345
			
 
				-	hs := make(HostSwitch)
			
 
				-	hs["example.com:12345"] = router
			
 
				-
			
 
				-	// Use the HostSwitch to listen and serve on port 12345
			
 
				-	log.Fatal(http.ListenAndServe(":12345", hs))
			
 
				-}
			
 
				-```
			
 
				-
			
 
				-### Basic Authentication
			
 
				-Another quick example: Basic Authentification (RFC 2617) for handles:
			
 
				-
			
 
				-```go
			
 
				-package main
			
 
				-
			
 
				-import (
			
 
				-    "bytes"
			
 
				-    "encoding/base64"
			
 
				-    "fmt"
			
 
				-    "github.com/julienschmidt/httprouter"
			
 
				-    "net/http"
			
 
				-    "log"
			
 
				-    "strings"
			
 
				-)
			
 
				-
			
 
				-func BasicAuth(h httprouter.Handle, user, pass []byte) httprouter.Handle {
			
 
				-	return func(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
			
 
				-		const basicAuthPrefix string = "Basic "
			
 
				-
			
 
				-		// Get the Basic Authentication credentials
			
 
				-		auth := r.Header.Get("Authorization")
			
 
				-		if strings.HasPrefix(auth, basicAuthPrefix) {
			
 
				-			// Check credentials
			
 
				-			payload, err := base64.StdEncoding.DecodeString(auth[len(basicAuthPrefix):])
			
 
				-			if err == nil {
			
 
				-				pair := bytes.SplitN(payload, []byte(":"), 2)
			
 
				-				if len(pair) == 2 &&
			
 
				-					bytes.Equal(pair[0], user) &&
			
 
				-					bytes.Equal(pair[1], pass) {
			
 
				-
			
 
				-					// Delegate request to the given handle
			
 
				-					h(w, r, ps)
			
 
				-					return
			
 
				-				}
			
 
				-			}
			
 
				-		}
			
 
				-
			
 
				-		// Request Basic Authentication otherwise
			
 
				-		w.Header().Set("WWW-Authenticate", "Basic realm=Restricted")
			
 
				-		http.Error(w, http.StatusText(http.StatusUnauthorized), http.StatusUnauthorized)
			
 
				-	}
			
 
				-}
			
 
				-
			
 
				-func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
			
 
				-    fmt.Fprint(w, "Not protected!\n")
			
 
				-}
			
 
				-
			
 
				-func Protected(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
			
 
				-    fmt.Fprint(w, "Protected!\n")
			
 
				-}
			
 
				-
			
 
				-func main() {
			
 
				-    user := []byte("gordon")
			
 
				-    pass := []byte("secret!")
			
 
				-    
			
 
				-    router := httprouter.New()
			
 
				-    router.GET("/", Index)
			
 
				-    router.GET("/protected/", BasicAuth(Protected, user, pass))
			
 
				-
			
 
				-    log.Fatal(http.ListenAndServe(":8080", router))
			
 
				-}
			
 
				-```
			
 
				-
			
 
				-## Chaining with the NotFound handler
			
 
				-
			
 
				-**NOTE: It might be required to set [Router.HandleMethodNotAllowed](http://godoc.org/github.com/julienschmidt/httprouter#Router.HandleMethodNotAllowed) to `false` to avoid problems.**
			
 
				-
			
 
				-You can use another [http.HandlerFunc](http://golang.org/pkg/net/http/#HandlerFunc), for example another router, to handle requests which could not be matched by this router by using the [Router.NotFound](http://godoc.org/github.com/julienschmidt/httprouter#Router.NotFound) handler. This allows chaining.
			
 
				-
			
 
				-### Static files
			
 
				-The `NotFound` handler can for example be used to serve static files from the root path `/` (like an index.html file along with other assets):
			
 
				-```go
			
 
				-// Serve static files from the ./public directory
			
 
				-router.NotFound = http.FileServer(http.Dir("public")).ServeHTTP
			
 
				-```
			
 
				-
			
 
				-But this approach sidesteps the strict core rules of this router to avoid routing problems. A cleaner approach is to use a distinct sub-path for serving files, like `/static/*filepath` or `/files/*filepath`.
			
 
				-
			
 
				-## Web Frameworks based on HttpRouter
			
 
				-If the HttpRouter is a bit too minimalistic for you, you might try one of the following more high-level 3rd-party web frameworks building upon the HttpRouter package:
			
 
				-* [Ace](https://github.com/plimble/ace): Blazing fast Go Web Framework
			
 
				-* [api2go](https://github.com/univedo/api2go): A JSON API Implementation for Go
			
 
				-* [Gin](https://github.com/gin-gonic/gin): Features a martini-like API with much better performance
			
 
				-* [Goat](https://github.com/bahlo/goat): A minimalistic REST API server in Go
			
 
				-* [Hikaru](https://github.com/najeira/hikaru): Supports standalone and Google AppEngine
			
 
				-* [Hitch](https://github.com/nbio/hitch): Hitch ties httprouter, [httpcontext](https://github.com/nbio/httpcontext), and middleware up in a bow
			
 
				-* [kami](https://github.com/guregu/kami): A tiny web framework using x/net/context
			
 
				-* [Medeina](https://github.com/imdario/medeina): Inspired by Ruby's Roda and Cuba
			
 
				-* [Neko](https://github.com/rocwong/neko): A lightweight web application framework for Golang
			
 
				-* [Roxanna](https://github.com/iamthemuffinman/Roxanna): An amalgamation of httprouter, better logging, and hot reload
			
 
				-* [siesta](https://github.com/VividCortex/siesta): Composable HTTP handlers with contexts
