Node.js和Socket.io创建空间

这可能会有所帮助：

var usernames = {};
var rooms = ['Lobby'];
io.sockets.on('connection', function(socket) {
socket.on('adduser', function(username) {
socket.username = username;
socket.room = 'Lobby';
usernames[username] = username;
socket.join('Lobby');
socket.emit('updatechat', 'SERVER', 'you have connected to Lobby');
socket.broadcast.to('Lobby').emit('updatechat', 'SERVER', username + ' has connected to this room');
socket.emit('updaterooms', rooms, 'Lobby');
});
socket.on('create', function(room) {
rooms.push(room);
socket.emit('updaterooms', rooms, socket.room);
});
socket.on('sendchat', function(data) {
io.sockets["in"](socket.room).emit('updatechat', socket.username, data);
});
socket.on('switchRoom', function(newroom) {
var oldroom;
oldroom = socket.room;
socket.leave(socket.room);
socket.join(newroom);
socket.emit('updatechat', 'SERVER', 'you have connected to ' + newroom);
socket.broadcast.to(oldroom).emit('updatechat', 'SERVER', socket.username + ' has left this room');
socket.room = newroom;
socket.broadcast.to(newroom).emit('updatechat', 'SERVER', socket.username + ' has joined this room');
socket.emit('updaterooms', rooms, newroom);
});
socket.on('disconnect', function() {
delete usernames[socket.username];
io.sockets.emit('updateusers', usernames);
socket.broadcast.emit('updatechat', 'SERVER', socket.username + ' has disconnected');
socket.leave(socket.room);
});
});
