Socket IO WebSocket请求被企业防火墙阻止。 [英] Socket IO WebSocket requests blocked by corporate firewalls.

问题描述

从企业防火墙/代理后面使用socket.io模块的解决方案是什么？这是我使用的代码。

What is the solution to using socket.io module from behind corporate firewall/proxy? This is the code I am using.

// setup express server
var app = express()
var serv = http.createServer(app);
serv.listen(80);

// setup socket io - listens in on express store as well for sessions
var io = require('socket.io').listen(serv);

推荐答案

我有一个类似的问题，我最终失去了websocket完全：

I had a similar issue and I ended up disabling websocket entirely:

io.configure('production', function(){
  io.set('transports', ['xhr-polling']);
});

XHR投票功能无处不在，但每个人都有更大的开销（即使只有5％的用户实际需要它）

XHR-polling works everywhere, but has a much bigger overhead for everyone (even if only 5% of users actually need it).

好消息是，即将推出的1.0版本的Socket.IO将会解决这个问题：

Good news is, the upcoming 1.0 version of Socket.IO will fix this:

与以前的Socket.IO核心不同，它始终首先建立一个长轮询连接，然后尝试升级到更好的运输，这是测试在一边。

Unlike the previous Socket.IO core, it always establishes a long-polling connection first, then tries to upgrade to better transports that are "tested" on the side.
