以下似乎有效：
apiRouter := mux.NewRouter()router.PathPrefix("/api/").Handler(http.StripPrefix("/api", adapt(apiRouter, checkTokenHandler)))apiRouter.Methods(http.MethodGet). Path("/path/to/handler").Handler(handleAPICall)// Note that `/api` has been removed from the path.哪里
func adapt(h http.Handler, adapters ...func(http.Handler) http.Handler) http.Handler { for _, adapter := range adapters { h = adapter(h) } return h}和
func checkTokenHandler(h http.Handler) http.Handler { return http.HandlerFunc(func(res http.ResponseWriter, req *http.Request) { // Check the security cookie. h.ServeHTTP(res, req) })}
