|

Package context stores values shared during a request lifetime.
|
||||
|
||||
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")
|
||||
```
|
||||
|
||||
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)
|
||||
```
|
||||
### Listing Routes
|
||||
|
||||
Routes on a mux can be listed using the Router.Walk method—useful for generating documentation:
|
||||
|
||||
```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.Walk(func(route *mux.Route, router *mux.Router, ancestors []*mux.Route) error {
|
||||
t, err := route.GetPathTemplate()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
// p will contain regular expression is compatible with regular expression in Perl, Python, and other languages.
|
||||
// for instance the regular expression for path '/articles/{id}' will be '^/articles/(?P<v0>[^/]+)$'
|
||||
p, err := route.GetPathRegexp()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
m, err := route.GetMethods()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
fmt.Println(strings.Join(m, ","), t, p)
|
||||
return nil
|
||||
})
|
||||
http.Handle("/", r)
|
||||
}
|
||||
```
|
||||
|
||||
### 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
|
||||
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.Walk(func(route *mux.Route, router *mux.Router, ancestors []*mux.Route) error {
|
||||
t, err := route.GetPathTemplate()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
// p will contain a regular expression that is compatible with regular expressions in Perl, Python, and other languages.
|
||||
// For example, the regular expression for path '/articles/{id}' will be '^/articles/(?P<v0>[^/]+)$'.
|
||||
p, err := route.GetPathRegexp()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
m, err := route.GetMethods()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
fmt.Println(strings.Join(m, ","), t, p)
|
||||
return nil

})
|

```
|
||||
|
||||
## 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")
|
||||

// URL builds a URL for the route.
|
||||
//
|
||||
// It accepts a sequence of key/value pairs for the route variables. For
|
||||
// example, given this route:
|
||||
//
|
||||
// r := mux.NewRouter()
|
||||
// r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
|
||||
// Name("article")
|
||||
//
|

// ...a URL for it can be built using:
|
||||
//
|
||||
// url, err := r.Get("article").URL("category", "technology", "id", "42")
|
||||
//
|
||||
// ...which will return an url.URL with the following path:
|
||||
//
|
||||
// "/articles/technology/42"
|
||||
//

//

// url, err := r.Get("article").URL("subdomain", "news",
|
||||
// "category", "technology",
|
||||
// "id", "42")

# Contributor Covenant Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to creating a positive environment include:
|
||||
|
||||
* Using welcoming and inclusive language
|
||||
* Being respectful of differing viewpoints and experiences
|
||||
* Gracefully accepting constructive criticism
|
||||
* Focusing on what is best for the community
|
||||
* Showing empathy towards other community members
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery and unwelcome sexual attention or advances
|
||||
* Trolling, insulting/derogatory comments, and personal or political attacks
|
||||
* Public or private harassment
|
||||
* Publishing others' private information, such as a physical or electronic address, without explicit permission
|
||||
* Other conduct which could reasonably be considered inappropriate in a professional setting
|
||||
|
||||
## Our Responsibilities
|
||||
|
||||
Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
|
||||
|
||||
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at i@dario.im. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
|
||||
|
||||
Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
|
||||
|
||||
## Attribution
|
||||
|
||||
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. Also maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
|
||||
|
||||
if err := mergo.Merge(&dst, src); err != nil {
|
||||
// ...
|
||||
}
|
||||
```go
|
||||
if err := mergo.Merge(&dst, src); err != nil {
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Also, you can merge overwriting values using MergeWithOverwrite.
|
||||
|
||||
```go
|
||||
if err := mergo.MergeWithOverwrite(&dst, src); err != nil {
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Additionally, you can map a map[string]interface{} to a struct (and otherwise, from struct to map), following the same restrictions as in Merge(). Keys are capitalized to find each corresponding exported field.
|
||||
|
||||
if err := mergo.Map(&dst, srcMap); err != nil {
|
||||
// ...
|
||||
}
|
||||
```go
|
||||
if err := mergo.Map(&dst, srcMap); err != nil {
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as map[string]interface{}. They will be just assigned as values.
