Socket.IO不能在Windows和Chrome上运行

我使用node.js（0.10.10），socket.io（0.9.16）和Express（3.2.6）创build了一个类似于聊天服务器和客户端的Facebook。 在所有浏览器（包括所有版本的Internet Explorer）中都可以正常工作，但Windows上的Firefox（21.0）和Chrome（27.0.1453.116）无法正常工作。 它在OS X上的所述浏览器中工作。

当我尝试通过查看错误事件的返回数据来debugging错误时，数据总是未定义的。 我已经尝试了所有可能的运输。

这是我用来在Windows和Chrome上testing的聊天应用程序的简化代码：

客户：

<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> 

服务器：

 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); 

在Windows中将单个用户与Chrome连接时，这是来自服务器的debugging日志：

Answer 1

你可以使用下面的代码来解决你的问题

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

Answer 2

我刚刚发现，这是由于在Chrome和Firefox中遇到问题的人的反病毒。 显然它阻止了websocket，甚至在这些浏览器上进行轮询。 我也将端口从8080更改为8079。
