Golang : Gorrila set route name and get the current route name
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)
to
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.
