Question

在我开发的macchine上，我使用nginx作为websocket的代理服务器，具有以下配置：

server {
  listen       80;

  location /socket.io {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-NginX-Proxy true;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;

    proxy_set_header Host $host;
    proxy_pass http://127.0.0.1:3001;
    proxy_redirect off;
  }

  location / {
    proxy_pass http://trunk.alban:81;
    client_max_body_size 500M;

  }
}

当我通过firefox从同一个macchine访问时，websockets正确连接并开始交换消息：

[root@localhost nodejs]# node websocket.js 

2014-12-04 10:27:16 ==> Listening on port: 3001
2014-12-04 10:27:16 ==> Auth token: alyt4qxs9k9k95a7q1if6r3a8b7yzaor
2014-12-04 10:27:29 ==> Client authorized: alyt4qxs9k9k95a7q1if6r3a8b7yzaor == alyt4qxs9k9k95a7q1if6r3a8b7yzaor

2014-12-04 10:27:35 ==> Broadcasting clients: amend-view-status_13 {}

但是当我从另一台机器进行访问时，它会连接，但它不会发送/接收任何消息，只是在交换协议中循环，连接和断开连接：

2014-12-04 10:32:23 ==> Client authorized: alyt4qxs9k9k95a7q1if6r3a8b7yzaor == alyt4qxs9k9k95a7q1if6r3a8b7yzaor

我安装了nginx 1.6.2和socket.io 1.2.1。

我已禁用所有可能的防火墙。

注意：如果我将nginx作为代理服务器删除，只需直接插入socket.io服务器，它就可以在任何机器中正常工作。

NOTE2 ：强制使用轮询，它可以正常工作。似乎是nginx / ws协议的一个问题...

有什么想法吗？

好的我发现了问题：在客户端我设置了transports选项：

this.socket = io.connect(this.adress, {query: 'token='+this.token /* , resource: 'ws/socket.io' */, transports:['websocket', 'polling']});

删除它：

this.socket = io.connect(this.adress, {query: 'token='+this.token});

IT工作，从任何远程连接！我无法解释为什么但它有效。

希望这对任何其他用户都有帮助

Nginx作为sockio.io websocket的代理服务器无法在远程工作
