Question

我想创建具有统一性和nodejs的在线tic tac，当我进入房间中的两个玩家时，两个玩家自动进入房间！注意：每个房间最多有两个玩家

问题：

玩家在连接后立即断开连接

和

io.sockets.clients（）。长度不起作用

var io = require('socket.io')(process.env.PORT || 3000);
var shortid = require('shortid');
console.log('server started');
var usernames = {};
var ids = {};
var rooms = [];
var roomExist = false;//true if a room exist with one player in there
var lastRoom ;  // id of room  with one player
var numClients = 0;
io.sockets.on('connection',function(socket){
    socket.on('addUser',function(username){
        socket.username = username;
    });
    socket.id = shortid.generate();
    socket.emit('yourId',socket.id);
    if (roomExist){//Player 2 joined
        socket.room = lastRoom;
        socket.join(lastRoom);
        roomExist = false;
        console.log('J client by id' ,socket.id,'by name',socket.username,'joined room',socket.room);
        console.log('number of clients is :',io.sockets.clients().length);
        socket.broadcast.to(socket.room).emit('spawn');
        socket.on('move',function(data){
            console.log('client moved',JSON.stringify(data));
            socket.broadcast.to(socket.room).emit('move',data);
        });
    }
    else {//Player 1 joined
        lastRoom = shortid.generate();
        rooms.push(lastRoom);
        socket.room = lastRoom;
        socket.join(lastRoom);
        roomExist = true;
        console.log('C client by id' ,socket.id,'by name',socket.username,'joined room',socket.room);
        console.log('number of clients is :',io.sockets.clients().length);
        socket.emit('wait'); // wait for player 2
        socket.on('move',function(data){
            console.log('client moved',JSON.stringify(data));
            socket.broadcast.to(socket.room).emit('move',data);
        });
    }
    socket.on('disconnect',function(){
        delete usernames[socket.username];
        delete usernames[socket.username];
        console.log('client',socket.username,'disconnected');
        io.sockets.emit('updateusers', usernames);
        socket.broadcast.emit('updatechat', 'SERVER', socket.username + ' has disconnected');
        socket.leave(socket.room);
    });
});

回答可能有点晚，但是在socket.io 2.2.0中，您应该使用：

io.sockets.clients.length

您在客户之后有括号

在nodejs中当我进入一个房间中的两个玩家时，玩家已经断开连接
