		w.Write([]byte(fmt.Sprintf("hello world Method:%s\n", r.Method)))
	}).All()
	m.HandleFunc("/hello/:key/world/:value", func(w http.ResponseWriter, r *http.Request) {
		params := m.Params(r)
		w.Write([]byte(fmt.Sprintf("hello key:%s value:%s\n", params["key"], params["value"])))
	}).GET().POST().PUT().DELETE()
	m.Group("/group", func(m *mux.Mux) {
		m.HandleFunc("/foo/:id", func(w http.ResponseWriter, r *http.Request) {
			params := m.Params(r)
			w.Write([]byte(fmt.Sprintf("group/foo id:%s\n", params["id"])))
		}).GET()
		m.HandleFunc("/bar/:id", func(w http.ResponseWriter, r *http.Request) {
