mux
===
[![GoDoc](https://godoc.org/github.com/gorilla/mux?status.svg)](https://godoc.org/github.com/gorilla/mux)
[![Build Status](https://travis-ci.org/gorilla/mux.png?branch=master)](https://travis-ci.org/gorilla/mux)
Package gorilla/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 and paths 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)
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"]
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)
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 variables:
r := mux.NewRouter()
r.Host("{subdomain}.domain.com").
Path("/articles/{category}/{id:[0-9]+}").
HandlerFunc(ArticleHandler).
Name("article")
// url.String() will be "http://news.domain.com/articles/technology/42"
url, err := r.Get("article").URL("subdomain", "news",
"category", "technology",
"id", "42")
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")
## Full Example
Here's a complete, runnable example of a small mux based server:
```go
package main
import (
"net/http"
"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
http.ListenAndServe(":8000", r)
}
```

# 2.1.0 / 2018-08-02
* Add AutoEnv feature
# 2.0.0 / 2018-08-02
* Breaking: Ensure an empty default string does not yield a slice with 1 element
Though this is a just a tiny change it does change the default behaviour, so I'm marking this as a breaking change. You should ensure your code is fine with the changes.
# 1.2.0 / 2017-06-19
* Add ParseAndValidate method
# 1.1.0 / 2016-06-28
* Support time.Duration config parameters
* Added goreportcard badge

## Usage
As a first step define a struct holding your configuration:
A very simple usecase is to just configure a struct inside the vars section of your `main.go` and to parse the commandline flags from the `main()` function:
```go
type config struct {
Username string `default:"unknown" flag:"user" description:"Your name"`
Details struct {
Age int `default:"25" flag:"age" env:"age" description:"Your age"`
}
}
```
package main
Next create an instance of that struct and let `rconfig` fill that config:
import (
"fmt"
"github.com/Luzifer/rconfig"
)
```go
var cfg config
func init() {
cfg = config{}
rconfig.Parse(&cfg)
}
```
var (
cfg = struct {
Username string `default:"unknown" flag:"user" description:"Your name"`
Details struct {
Age int `default:"25" flag:"age" env:"age" description:"Your age"`
}
}{}
)
You're ready to access your configuration:
```go
func main() {
rconfig.Parse(&cfg)
fmt.Printf("Hello %s, happy birthday for your %dth birthday.",
cfg.Username,
cfg.Details.Age)
cfg.Username,
cfg.Details.Age)
}

http://www.gorillatoolkit.org/pkg/mux
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))
}
```

## Disable sorting of flags
`pflag` allows you to disable sorting of flags for help and usage message.
**Example**:
```go
flags.BoolP("verbose", "v", false, "verbose output")
flags.String("coolflag", "yeaah", "it's really cool flag")
flags.Int("usefulflag", 777, "sometimes it's very useful")
flags.SortFlags = false
flags.PrintDefaults()
```
**Output**:
```
-v, --verbose verbose output
--coolflag string it's really cool flag (default "yeaah")
--usefulflag int sometimes it's very useful (default 777)
```
## Supporting Go flags when using pflag
In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
to support flags defined by third-party dependencies (e.g. `golang/glog`).

Package validator
================
Package validator implements variable validations
Installation
============
Just use go get.
```bash
go get gopkg.in/validator.v2
```
And then just import the package into your own code.
```go
import (
"gopkg.in/validator.v2"
)
```
Usage
=====
Please see http://godoc.org/gopkg.in/validator.v2 for detailed usage docs.
A simple example would be.
```go
type NewUserRequest struct {
Username string `validate:"min=3,max=40,regexp=^[a-zA-Z]*$"`
Name string `validate:"nonzero"`
Age int `validate:"min=21"`
Password string `validate:"min=8"`
}
nur := NewUserRequest{Username: "something", Age: 20}
if errs := validator.Validate(nur); errs != nil {
// values not valid, deal with errors here
}
```
Builtin validators
Here is the list of validators buildin in the package. Validators buildin
will check the element pointed to if the value to check is a pointer.
The `nil` pointer is treated as a valid value by validators buildin other
than `nonzero`, so you should to use `nonzero` if you don't want to
accept a `nil` pointer.
```
len
For numeric numbers, len will simply make sure that the
value is equal to the parameter given. For strings, it
checks that the string length is exactly that number of
characters. For slices, arrays, and maps, validates the
number of items. (Usage: len=10)
max
For numeric numbers, max will simply make sure that the
value is lesser or equal to the parameter given. For strings,
it checks that the string length is at most that number of
characters. For slices, arrays, and maps, validates the
number of items. (Usage: max=10)
min
For numeric numbers, min will simply make sure that the value
is greater or equal to the parameter given. For strings, it
checks that the string length is at least that number of
characters. For slices, arrays, and maps, validates the
number of items. (Usage: min=10)
nonzero
This validates that the value is not zero. The appropriate
zero value is given by the Go spec (e.g. for int it's 0, for
string it's "", for pointers is nil, etc.) For structs, it
will not check to see if the struct itself has all zero
values, instead use a pointer or put nonzero on the struct's
keys that you care about. (Usage: nonzero)
regexp
Only valid for string types, it will validator that the
value matches the regular expression provided as parameter.
(Usage: regexp=^a.*b$)
```
Custom validators
It is possible to define custom validators by using SetValidationFunc.
First, one needs to create a validation function.
```go
// Very simple validator
func notZZ(v interface{}, param string) error {
st := reflect.ValueOf(v)
if st.Kind() != reflect.String {
return errors.New("notZZ only validates strings")
}
if st.String() == "ZZ" {
return errors.New("value cannot be ZZ")
}
return nil
}
```
Then one needs to add it to the list of validators and give it a "tag"
name.
```go
validator.SetValidationFunc("notzz", notZZ)
```
Then it is possible to use the notzz validation tag. This will print
"Field A error: value cannot be ZZ"
```go
type T struct {
A string `validate:"nonzero,notzz"`
}
t := T{"ZZ"}
if errs := validator.Validate(t); errs != nil {
fmt.Printf("Field A error: %s\n", errs["A"][0])
}
```
You can also have multiple sets of validator rules with SetTag().
```go
type T struct {
A int `foo:"nonzero" bar:"min=10"`
}
t := T{5}
SetTag("foo")
validator.Validate(t) // valid as it's nonzero
SetTag("bar")
validator.Validate(t) // invalid as it's less than 10
```
SetTag is probably better used with multiple validators.
```go
fooValidator := validator.NewValidator()
fooValidator.SetTag("foo")
barValidator := validator.NewValidator()
barValidator.SetTag("bar")
fooValidator.Validate(t)
barValidator.Validate(t)
```
This keeps the default validator's tag clean. Again, please refer to
godocs for a lot of more examples and different uses.
Pull requests policy
====================
tl;dr. Contributions are welcome.
The repository is organized in version branches. Pull requests to, say, the
`v2` branch that break API compatibility will not be accepted. It is okay to
break the API in master, *not in the branches*.
As for validation functions, the preference is to keep the main code simple
and add most new functions to the validator-contrib repository.
https://github.com/go-validator/validator-contrib
For improvements and/or fixes to the builtin validation functions, please
make sure the behaviour will not break existing functionality in the branches.
If you see a case where the functionality of the builtin will change
significantly, please send a pull request against `master`. We can discuss then
whether the changes should be incorporated in the version branches as well.

Package validator implements value validations based on struct tags.
In code it is often necessary to validate that a given value is valid before
using it for something. A typical example might be something like this.
if age < 18 {
return error.New("age cannot be under 18")
}
This is a simple enough example, but it can get significantly more complex,
especially when dealing with structs.
l := len(strings.Trim(s.Username))
if l < 3 || l > 40 || !regexp.MatchString("^[a-zA-Z]$", s.Username) || s.Age < 18 || s.Password {
return errors.New("Invalid request")
}
You get the idea. Package validator allows one to define valid values as
struct tags when defining a new struct type.
type NewUserRequest struct {
Username string `validate:"min=3,max=40,regexp=^[a-zA-Z]*$"`
Name string `validate:"nonzero"`
Age int `validate:"min=18"`
Password string `validate:"min=8"`
}
Then validating a variable of type NewUserRequest becomes trivial.
nur := NewUserRequest{Username: "something", ...}
if errs := validator.Validate(nur); errs != nil {
// do something
}
Builtin validator functions
Here is the list of validator functions builtin in the package.
len
For numeric numbers, len will simply make sure that the value is
equal to the parameter given. For strings, it checks that
the string length is exactly that number of characters. For slices,
arrays, and maps, validates the number of items. (Usage: len=10)
max
For numeric numbers, max will simply make sure that the value is
lesser or equal to the parameter given. For strings, it checks that
the string length is at most that number of characters. For slices,
arrays, and maps, validates the number of items. (Usage: max=10)
min
For numeric numbers, min will simply make sure that the value is
greater or equal to the parameter given. For strings, it checks that
the string length is at least that number of characters. For slices,
arrays, and maps, validates the number of items. (Usage: min=10)
nonzero
This validates that the value is not zero. The appropriate zero value
is given by the Go spec (e.g. for int it's 0, for string it's "", for
pointers is nil, etc.) Usage: nonzero
regexp
Only valid for string types, it will validate that the value matches
the regular expression provided as parameter. (Usage: regexp=^a.*b$)
Note that there are no tests to prevent conflicting validator parameters. For
instance, these fields will never be valid.
...
A int `validate:"max=0,min=1"`
B string `validate:"len=10,regexp=^$"
...
Custom validation functions
It is possible to define custom validation functions by using SetValidationFunc.
First, one needs to create a validation function.
// Very simple validation func
func notZZ(v interface{}, param string) error {
st := reflect.ValueOf(v)
if st.Kind() != reflect.String {
return validate.ErrUnsupported
}
if st.String() == "ZZ" {
return errors.New("value cannot be ZZ")
}
return nil
}
Then one needs to add it to the list of validation funcs and give it a "tag" name.
validate.SetValidationFunc("notzz", notZZ)
Then it is possible to use the notzz validation tag. This will print
"Field A error: value cannot be ZZ"
type T struct {
A string `validate:"nonzero,notzz"`
}
t := T{"ZZ"}
if errs := validator.Validate(t); errs != nil {
fmt.Printf("Field A error: %s\n", errs["A"][0])
}
To use parameters, it is very similar.
// Very simple validator with parameter
func notSomething(v interface{}, param string) error {
st := reflect.ValueOf(v)
if st.Kind() != reflect.String {
return validate.ErrUnsupported
}
if st.String() == param {
return errors.New("value cannot be " + param)
}
return nil
}
And then the code below should print "Field A error: value cannot be ABC".
validator.SetValidationFunc("notsomething", notSomething)
type T struct {
A string `validate:"notsomething=ABC"`
}
t := T{"ABC"}
if errs := validator.Validate(t); errs != nil {
fmt.Printf("Field A error: %s\n", errs["A"][0])
}
As well, it is possible to overwrite builtin validation functions.
validate.SetValidationFunc("min", myMinFunc)
And you can delete a validation function by setting it to nil.
validate.SetValidationFunc("notzz", nil)
validate.SetValidationFunc("nonzero", nil)
Using a non-existing validation func in a field tag will always return
false and with error validate.ErrUnknownTag.
Finally, package validator also provides a helper function that can be used
to validate simple variables/values.
// errs: nil
errs = validator.Valid(42, "min=10, max=50")
// errs: [validate.ErrZeroValue]
errs = validator.Valid(nil, "nonzero")
// errs: [validate.ErrMin,validate.ErrMax]
errs = validator.Valid("hi", "nonzero,min=3,max=2")
Custom tag name
In case there is a reason why one would not wish to use tag 'validate' (maybe due to
a conflict with a different package), it is possible to tell the package to use
a different tag.
validator.SetTag("valid")
Then.
Type T struct {
A int `valid:"min=8, max=10"`
B string `valid:"nonzero"`
}
SetTag is permanent. The new tag name will be used until it is again changed
with a new call to SetTag. A way to temporarily use a different tag exists.
validator.WithTag("foo").Validate(t)
validator.WithTag("bar").Validate(t)
// But this will go back to using 'validate'
validator.Validate(t)
Multiple validators
You may often need to have a different set of validation
rules for different situations. In all the examples above,
we only used the default validator but you could create a
new one and set specific rules for it.
For instance, you might use the same struct to decode incoming JSON for a REST API
but your needs will change when you're using it to, say, create a new instance
in storage vs. when you need to change something.
type User struct {
Username string `validate:"nonzero"`
Name string `validate:"nonzero"`
Age int `validate:"nonzero"`
Password string `validate:"nonzero"`
}
Maybe when creating a new user, you need to make sure all values in the struct are filled,
but then you use the same struct to handle incoming requests to, say, change the password,
in which case you only need the Username and the Password and don't care for the others.
You might use two different validators.
type User struct {
Username string `creating:"nonzero" chgpw:"nonzero"`
Name string `creating:"nonzero"`
Age int `creating:"nonzero"`
Password string `creating:"nonzero" chgpw:"nonzero"`
}
var (
creationValidator = validator.NewValidator()
chgPwValidator = validator.NewValidator()
)
func init() {
creationValidator.SetTag("creating")
chgPwValidator.SetTag("chgpw")
}
...
func CreateUserHandler(w http.ResponseWriter, r *http.Request) {
var u User
json.NewDecoder(r.Body).Decode(&user)
if errs := creationValidator.Validate(user); errs != nil {
// the request did not include all of the User
// struct fields, so send a http.StatusBadRequest
// back or something
}
// create the new user
}
func SetNewUserPasswordHandler(w http.ResponseWriter, r *http.Request) {
var u User
json.NewDecoder(r.Body).Decode(&user)
if errs := chgPwValidator.Validate(user); errs != nil {
// the request did not Username and Password,
// so send a http.StatusBadRequest
// back or something
}
// save the new password
}
It is also possible to do all of that using only the default validator as long
as SetTag is always called before calling validator.Validate() or you chain the
with WithTag().
