将中间件与Golang Gorilla Mux子路由器一起使用

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)    })}
