只需创建一个包装器，在Go中就很容易了：
func HomeHandler(response http.ResponseWriter, request *http.Request) { fmt.Fprintf(response, "Hello home")}func Middleware(h http.Handler) http.Handler { return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { log.Println("middleware", r.URL) h.ServeHTTP(w, r) })}func main() { r := mux.NewRouter() r.HandleFunc("/", HomeHandler) http.Handle("/", Middleware(r))}
