您应该通过Web进行身份验证，返回cookie，然后再次携带cookie再次连接到websocket服务器. WS服务器可以验证cookie

You should do the authentication through web, return a cookie and then connect to the websocket server again, carrying the cookie. The WS server can validate the cookie

如果没有基于cookie的身份验证，或者根本不可能(例如另一个域中的WS服务器)，则必须创建自己的请求-响应消息进行登录.

If there is no cookie based authentication or it is just not possible (like the WS server in another domain), you will have to create your own request-response messages for login.
