退出后销毁握手。 socket.io [英] Destroying a handshake after logout. socket.io

问题描述

你好，我正在尝试在一个应用程序中建立聊天。我想知道的是，当用户注销网站时，如何还销毁与该会话相关联的socket.io握手，以便用户在注销时不能从另一个标签发送消息。

如果有任何帮助，我使用expressjs。

解决方案

如果有人找到这个并想知道我已经弄清楚了。
您可以访问套接字断开连接功能。我有对象的用户ID和他们的套接字ID，所以当有人退出我打电话

  app.get（/ logout函数（req，res）{
 //做其他注销东西
 sockets.disconnectUser（req.session.user_id）; 
} 
 
 //断开用户函数
 sockets.disconnectUser = function（user_id）{
 sockets.socket（users [user_id]）。disconnect（）; 
}

Hello I am trying to build chat into an application. What I am wondering is when the user logs out of the website how do I also destroy the socket.io handshake associated with that session so the user cannot send messages from say another tab when he is logged out.

I am using expressjs if that is any help.
解决方案
Well in case anyone ever find this and wants to know I did figure it out.
You can access the sockets disconnect function. I had object of users ids and their socket id so when someone logged out I called
app.get("/logout", function(req,res){
  //do other logging out stuff
  sockets.disconnectUser(req.session.user_id);
}

// Disconnect User function
sockets.disconnectUser = function(user_id){
  sockets.socket(users[user_id]).disconnect();
}
