Golang : Example of custom handler for Gorilla's Path usage.

In Gorilla WebToolkit's official documentation, the code fragment given in http://www.gorillatoolkit.org/pkg/mux#Route.Path does not show how to create custom handler to use together with Path() function.

 r := mux.NewRouter()

This tutorial will demonstrate how to create custom handler for Path() function. In this example, a custom http.Handler type must have a ServeHTTP method, otherwise the compiler will not compile the code.

 package main

 import (

 type greetHandler struct {
 gmux http.Handler 

 func (g *greetHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
 //w.Write([]byte("Hello from greetHandler's ServeHTTP"))

 name := mux.Vars(r)["name"]
 w.Write([]byte(fmt.Sprintf("Hello %s from greetHandler's ServeHTTP! ", name)))

 func main() {
 mx := mux.NewRouter()

 // bind gmux to mx(route)
 ghandler := &greetHandler{gmux : mx} 


 http.ListenAndServe(":8080", mx)

Hope this helps!
