Javascript Socket.io赢得'；t将消息发送到Disconect上的房间

基本上，我正在尝试使用Node.JS和angular创建一个快速聊天室

我已经使用了其他套接字事件，它们工作了，我不太明白为什么它们现在不想工作。真正奇怪的是，登录工作正常，但当涉及到注销，甚至使用我的断开连接方法时，服务器端没有发生任何事情，使用断开连接功能，

console.log

工作正常。但它不会发射

在角度方面，所有my

console.log都在运行，但在注销或卸载时，服务器上没有发生任何事件

在节点内部，我有三个事件

 socket.on('chat:userLogin', function(user) {
    socket.join('online-users');
    chatRoom[user.id] = user
    console.log('User Has logged in, chat room contains: ', chatRoom);
    io.sockets.in('online-users').emit('chat:usersOnline', chatRoom)
  })

  socket.on('chat:userLogout', function(userId) {
    console.log('User Id ' + userId + 'is logging out');
    delete chatRoom[userId]
    console.log('User Has logged out, chat room contains: ', chatRoom);
    io.sockets.in('online-users').emit('chat:userLeave', chatRoom);
    socket.leave('online-users');
  })

  socket.on('disconnect', function() {
    var userRoom = rooms[socket.roomId]

    if (chatRoom[socket.userId])
      delete chatRoom[socket.userId]

    io.sockets.in('online-users').emit('chat:userLeave', socket.userId);
    console.log('Emitting that users have left to: ', io.sockets.in('online-users'));
    socket.leave('online-users');
  }

在角度上，我有两个函数，它们发出这两个事件

  this.logout = function(userId) {
      console.log('Logging user out: ', userId);
      Socket.emit('chat:userLogout', userId);
      console.log('Logged out user?');
      delete this.userStore[userId]
    }

    this.login = function(userId) {
      console.log('Getting online user ', userId);
      var self = this;
      User.get({id: userId}, function(user) {
        self.userStore[userId] = user;
        Socket.emit('chat:userLogin', user);
      });
    }

它可能会解决您的问题，但您应该使用socket.broadcast.to（'roomname'），除非您希望将消息发送到房间中的所有套接字（包括发送消息的套接字）。所以你的代码看起来像

socket.on('chat:userLogin', function(user) {
   socket.join('online-users');
   chatRoom[user.id] = user
   console.log('User Has logged in, chat room contains: ', chatRoom);
   // emit to everyone else except the sender
   socket.broadcast.to('online-users').emit('chat:usersOnline', chatRoom);
})

socket.on('chat:userLogout', function(userId) {
   console.log('User Id ' + userId + 'is logging out');
   delete chatRoom[userId]
   socket.leave('online-users');
   // leaving the chat room here means we can emit to all people in the room
   io.sockets.in('online-users').emit('chat:userLeave', chatRoom);
   console.log('User Has logged out, chat room contains: ', chatRoom);

})

socket.on('disconnect', function() {
   var userRoom = rooms[socket.roomId]

   if (chatRoom[socket.userId])
      delete chatRoom[socket.userId]

   socket.leave('online-users');
   io.sockets.in('online-users').emit('chat:userLeave', socket.userId);

   console.log('Emitting that users have left to: ', io.sockets.in('online-users'));
}
