Question

这是一个重复的问题，虽然我想问一下。我想要所有用户名和＆amp;有socket.id谁当前连接到一个房间，如何得到它，

我尝试过： var clients = io.sockets.clients（'room1'）;

这是我的代码ref

// when the client emits 'adduser', this listens and executes
    socket.on('adduser', function(username){
        // store the username in the socket session for this client
        socket.username = username;
        // store the room name in the socket session for this client
    //  socket.myroom = 'room1';
        // add the client's username to the global list
        usernames[username] = username;
        // send client to room 1
        socket.join('room1');
        socket.join('room2');
        // echo to client they've connected
        socket.emit('updatechat', 'room1', 'you have connected to room1');
        socket.emit('updatechat', 'room2', 'you have connected to room2');
        // echo to room 1 that a person has connected to their room
        socket.broadcast.to('room1').emit('updatechat', 'room1', username + ' has connected to this room');
        socket.broadcast.to('room2').emit('updatechat', 'room2', username + ' has connected to this room');
        var clients = io.sockets.clients('room1'); 


        console.log('socket.id :'+ socket.id);

        console.log('projson :'+ clients);
        console.log('projson :'+ clients.socket.id);
        console.log('projson :'+ clients.socket);

    });

这是日志

如何获得socketid＆amp;用户名，任何帮助将不胜感激，谢谢

Answer 1

尝试

console.log(io.sockets.manager.rooms)

这会给你这样的东西：

{
    "room1":[socketidOfUser1,socketidOfUser2],
    "room2":[socketidOfUser3,socketidOfUser4],
}

看看这是否提供了您需要的信息
