Question

我在nodejs + socket.io中有一个简单的tcp连接服务器可以将数据发送到服务器，但我没有回来。

原谅我的英语我来自巴西

查看代码。

客户代码：

if(newY !== ymouse  || newX !== xmouse)
{
    socket.emit('chat', {playerX: playerX, playerY: playerY});
}

socket.on('chat',
            function (data)
            {
                console.log(data)

            //  $("p#data_recieved").append("<br />\r\n [position] {" + data.msgr + ": playerX = " + data.playerX + ", playerY = " + data.playerY + "}");
                document.getElementById("vy").innerHTML = data.X;
                document.getElementById("vx").innerHTML = data.y;



            }

服务器代码：

var io = require('socket.io').listen(8000);

io.sockets.on('connection',
    function (socket)
    {
    socket.on('chat',
        function (data)
        {
            var sender = 'unregistered';
            socket.get('nickname', 
                function (err, name)
                {
                    console.log('Chat message by ', name);
                    console.log('error ', err);
                    console.log('X: ' + data.playerX);
                    console.log('Y: ' + data.playerY);
                    sender = name;
                });

            socket.broadcast.emit('chat', { playerX : data.playerX, playerY : data.playerY, msg : data, msgr : sender});
        });

    socket.on('position',
        function (data)
        {
            var sender = 'unregistered';
            socket.get('nickname', 
                function (err, name)
                {
                    sender = name;
                });

            if(sender == 'unregistered')
                return;

            var playerX = data.playerX;
            var playerY = data.playerY;

            socket.broadcast.emit('position', {msgr : sender, playerX : playerX, playerY : data.playerY});
        });

    socket.on('register',
        function (name)
        {
            socket.set('nickname', name,
                function ()
                {
                    io.sockets.emit('chat', {msg : "naay nag apil2! si " + name + '!', msgr : "mr. server"});
                });
        });

});

你怎么能看到我能将数据发送到服务器但是没有反应服务器似乎运作良好

我留下一个简单连接的例子，你可以启发

服务器：

var simple = io
  .sockets
  .on('connection', function(socket) {
    socket.on('message', function(data) {
      socket.broadcast.send(data);
    });
    socket.on('disconnect', function() {
      // handle disconnect
    });
  });

客户端：

var socket = io.connect();
var content = $('#simple-content');
socket.on('connect', function() {
  $('#simple-form').css('display', 'block');
  content.append($('<p>').text('Connected'));  
});

socket.on('message', function(msg) {
  content.append($('<p>').text(msg)
         .append($('<em>').text(' from server')));
});

$('#simple-form').submit(function(e) {
  e.preventDefault();
  var textObj = $('#simple-text');   
  var msg = textObj.val();
  textObj.val('');
  content.append($('<p>').text(msg)
         .append($('<em>').text(' from me')));
  socket.send(msg);
});

我希望它会有所帮助！
