我使用node.js(0.10.10),socket.io(0.9.16)和Express(3.2.6)创建了一个像聊天服务器和客户端的Facebook。它适用于所有浏览器,包括所有版本的Internet Explorer,但Windows上的Firefox(21.0)和Chrome(27.0.1453.116)不起作用。它适用于OS X上的所述浏览器。
当我尝试通过查看错误事件的返回数据来调试错误时,数据始终是未定义的。我尝试了所有可能的运输工具。
这是我用于在Windows中的Chrome和Firefox上进行测试的聊天应用程序的简化代码:
客户端:
<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);
这是在Windows中将单个用户与Chrome连接时来自服务器的调试日志:

答案 0 :(得分:2)
您可以使用以下代码解决问题
io.configure(function () {
io.set("transports", ["xhr-polling"]);
io.set("polling duration", 10);
});
答案 1 :(得分:0)
我刚发现这是因为Chrome和Firefox出现问题的人的反病毒。显然它会阻止websockets甚至在这些浏览器上进行轮询。我还将端口从8080更改为8079.
