Socket.io客户端仅在每隔一次连接时加入文件室

我一直在尝试创建一个基本的通知系统，它使用Socket.io中的文件室。但是，由于某些原因，它只在每隔一次刷新页面时起作用

我简化了代码，使其更易于调试，但问题仍然存在。每次我刷新页面时，除了加入一个房间（只有一半的时间有效）之外，其他一切似乎都正常。会发生什么事

编辑：我正在使用Socket.io版本1.1.0和Node.js版本0.10.31 编辑2：增加了FunnyLookinHat的建议（但仍然不能解决问题）

客户端代码：

socket = io.connect('example.com:8081'),

socket.on('connect', function () {
    socket.on('startup', function(data) {
        console.log(data.message);
    });
    socket.emit('joinRoom');
});

var io = require('socket.io').listen(8081);

io.sockets.on('connection', function (socket) {

    console.log(socket.id + ' connected!');

    socket.emit('startup', { message: 'Socket started!' });

    socket.on('joinRoom', function(){
        console.log(socket.id + ' joining room lobby'); // prints on every other request
        socket.join('lobby');
    });

    socket.on('disconnect', function() {
        console.log(socket.id + ' disconnected!');
    });

});

Socket started!

比赛条件！尝试在客户端代码中执行以下操作：

socket = io.connect('example.com:8081'),

socket.on('connect', function () {
    socket.on('startup', function(data) {
        console.log(data.message);
    });

    socket.emit('joinRoom');
});

好消息，但是，在我修复之后，问题仍然存在。这似乎仍然是另外一回事。（为了减少混乱，我将使用此修复程序更新问题，因为它无法解决主要问题。）我也有类似的问题，可能是引擎盖下的一些讨厌的CORS东西，但我不确定。您是否在浏览器中打开同一内容并连接到同一站点？（

socket=io.connect（'example.com:8081'）

）请注意，拥有或不拥有

也很重要。我刚刚厌倦了socket.io。我改用Faye插座，从那以后就再也没有问题了！
