我正在尝试将一个额外的参数传递到我发送给Go服务器的请求中 -
websocket.create_connection("ws://<ip>:port/x/y?token="qwerty")
Go服务器实现如下 -
func main() {
err := config.Parse()
if err != nil {
glog.Error(err)
os.Exit(1)
return
}
flag.Parse()
defer glog.Flush()
router := mux.NewRouter()
http.Handle("/", httpInterceptor(router))
router.Handle("/v1/x", common.ErrorHandler(stats.GetS)).Methods("GET")
router.Handle("/v1/x/y", common.ErrorHandler(stats.GetS)).Methods("GET")
var listen = fmt.Sprintf("%s:%d", config.Config.Ip, config.Config.Port)
err = http.ListenAndServe(listen, nil)
if err != nil {
glog.Error(err)
os.Exit(1)
}
}
func httpInterceptor(router http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) {
startTime := time.Now()
if !auth.Auth(w, req) {
http.Error(w, "Failed authentication", 401)
return
}
router.ServeHTTP(w, req)
finishTime := time.Now()
elapsedTime := finishTime.Sub(startTime)
switch req.Method {
case "GET":
case "POST":
}
})
}
如何在Go服务器中查找和解析令牌,以便身份验证成功?
库函数
func ParseFromRequest(req *http.Request, keyFunc Keyfunc) (token *Token, err error) {
// Look for an Authorization header
if ah := req.Header.Get("Authorization"); ah != "" {
// Should be a bearer token
if len(ah) > 6 && strings.ToUpper(ah[0:6]) == "BEARER" {
return Parse(ah[7:], keyFunc)
}
}
// Look for "access_token" parameter
req.ParseMultipartForm(10e6)
if tokStr := req.Form.Get("access_token"); tokStr != "" {
return Parse(tokStr, keyFunc)
}
return nil, ErrNoTokenInRequest
}
req.ParseForm(); req.Form.Set("access_token", req.URL.Query().Get("token"))
,在这种情况下,ParseForm 将 req.Form 设置为 req.URL.Query()。第二次调用 req.URL.Query() 没有意义。 - Charlie Tumahai
