Golang : Gorrila set route name and get the current route name

Tags : golang gorilla route

Problem :

You want to know the current route that your user is using on your website and retrieve the name of the route. How to that with Gorrilla Web toolkit ?

Solution :

Before you can get the name of the route, first you need to give it a name.

For example :

 mx := mux.NewRouter()
 mx.HandleFunc("/", SayHelloWorld)


 mx := mux.NewRouter()
 mx.HandleFunc("/", SayHelloWorld).Name("home") // route named home

Next, get the current route from the user request(r *http.Request) and get the route name with GetName() function.

 func SayHelloWorld(w http.ResponseWriter, r *http.Request) {
 w.Write([]byte("Hello, World!"))

 route := mux.CurrentRoute(r)
 w.Write([]byte(fmt.Sprintf("Route name is %v ", route.GetName())))

Knowing the route name is useful in situation where you need to build URL. For example, to redirect user to the newly built URL.
