Socket.IO在Windows和Chrome瀏覽器中不起作用

Question

我使用node.js（0.10.10），socket.io（0.9.16）和Express（3.2.6）創建了一個類似於Facebook的聊天服務器和客戶端。它適用於所有瀏覽器，包括所有版本的Internet Explorer，但Windows上的Firefox（21.0）和Chrome（27.0.1453.116）無法正常工作。它在OS X上的所述瀏覽器中工作。

當我嘗試通過查看錯誤事件的返回數據來調試錯誤時，數據始終未定義。我嘗試了所有可能的運輸方式。

這是我在Windows中使用的Chrome和Firefox的測試聊天應用程序的簡化代碼：

客戶：

<script src="http://www.xserverx.com:8080/socket.io/socket.io.js"></script> 
<script> 
    var ioUrl = 'http://www.xserverx.eu:8080'; 
    var socket = io.connect(ioUrl, { 
     'reconnect': true, 
     'reconnection delay': 1500, 
     //'sync disconnect on unload': true 
    }); 

    $('#send-button').click(function() { 
     socket.emit('message', { message: $('#message').val() }); 
    }); 

    // Event listeners 
    socket.on('connect', function() { 
     // Display socket transport type 
     // Is empty in Chrome and Firefox on Windows 
     $('#transport-type').html(socket.socket.transport.name); 
    }); 

    socket.on('onlinechange', function(data) { 
     $('#users-online').html(data.online); 
    }); 

    socket.on('message', function(data) { 
     $('#chat').append('<p>' + data.message + '</p>'); 
    }); 

    socket.on('error', function(data) { 
     $('#errors').html('Error: Error. ' + JSON.stringify(data)); 
    }); 
    socket.on('connect_failed', function(data) { 
     $('#errors').html('Error: Connect failed. ' + JSON.stringify(data)); 
    }); 
    socket.on('reconnect_failed', function(data) { 
     $('#errors').html('Error: Reconnect failed. ' + JSON.stringify(data)); 
    }); 
</script> 

服務器：

var express = require('express'), 
    app = express(), 
    sio = require('socket.io'); 

var port = 8080; 

var io = sio.listen(app.listen(port)); 
    io.set('log level', 1); // Only show warnings and errors 
    io.set('polling duration', 10); 
    io.enable('browser client minification'); 
    io.enable('browser client gzip'); 


var totalOnline = 0; 

// Server 
io.sockets.on('connection', function(socket) { 
    socket.setMaxListeners(0); 

    console.log('---- New user online ----'); 
    totalOnline++; 
    socket.emit('onlinechange', { online: totalOnline }); 

    socket.on('disconnect', function() { 
     console.log('---- User disconnected ----'); 

     totalOnline--; 

     socket.emit('onlinechange', { online: totalOnline }); 
    }); 

    socket.on('message', function(data) { 
     io.sockets.emit('message', { message: data.message }); 
    }); 
}); 
console.log('Listening on port ' + port); 

這是將單個用戶與Chrome連接時來自服務器的調試日誌Windows系統：

Answer 1

您可以使用下面的代碼爲您解決問題

io.configure(function() { 
    io.set("transports", ["xhr-polling"]); 
    io.set("polling duration", 10); 
}); 

Answer 2

我剛剛發現這是由於在Chrome和Firefox中遇到問題的人的反病毒。顯然它會阻止websocket，甚至在這些瀏覽器上進行輪詢。我也改變從8080端口到8079.
