socket.io从两个房间加入客户

Question

我想和两个房间的客户一起加入新房间。有没有办法实现这个目标？像：

io.sockets.clients(room1 , room2).join(room 3);

Answer 1

var rooms = ['room1', 'room2', room3]; // list of rooms

socket.join('room1'); // assign the room on connection

var clients = io.sockets.clients(rooms[0]); // list of all clients in room1

for (client in clients)
    {
        clients[client].leave(rooms[0]); // leave room1
        clients[client].join(rooms[2]); // join room3
    }

对room2重复相同的操作。希望这有帮助

Answer 2

对于使用socket.IO版本1.0或更高版本的用户，这可能无效。请尝试使用以下代码。

var clients = io.sockets.adapter.rooms['Current Room Name'];

for (var clientId in clients ) {

     //this is the socket of each client in the room.
     var clientSocket = io.sockets.connected[clientId];

     //If you want, you can remove the client form the first(current) room
     //clientSocket.leave('current room');

     clientSocket.join('new room to join');   

}
