使用這個https://github.com/praveen001/go-passport帶有 passsport 中間件的路徑：app.Put("/api/auth/login", p.Authenticate("local", MyHandler))護照認證功能：// Authenticate calls `Strategy.Authenticate` method of registered strategies, and checks the `passport.Result` returned by it.//// The result is stored in the request context with `passport.CtxKey` as key.//func (p *Passport) Authenticate(name string, h http.HandlerFunc) http.HandlerFunc {    return func(w http.ResponseWriter, r *http.Request) {        s, ok := p.Options.strategies[name]        if !ok {            w.WriteHeader(404)            return        }        s.Authenticate(w, r, func(res *Result) {            res.StrategyName = name                        ctx := context.WithValue(r.Context(), CtxKey, res)            h.ServeHTTP(w, r.WithContext(ctx))        })    }}因此，這會附加來自我的 auth 方法的響應并返回一個 http.HandleFunc，我可以自己定義（MyHandler）。func MyHandler(w http.ResponseWriter, r *http.Request) {    // Where is the data attached from the Authenticate func?    w.Header().Add("Content-Type", "application/json")    w.WriteHeader(401)    io.WriteString(w, `{"status":"ok"}`)}我不明白在哪里可以從Authenticatefunc 獲取附加數(shù)據(jù)。評論說：“//結果存儲在請求上下文中，passport.CtxKey作為鍵”。我在r *http.Request.
