而且很奇怪我用curl直接访问网址是可以正常返回200的，就是这样:
curl http://mydomain:80/socket.io/1/?EIO=2&transport=polling&b64=true
我看代码里用了NSURLConnection来请求，就返回404了，好奇怪
嗯，的确，curl是可以正常的。这个原因还是不明。
但是就你的服务器，如果加上强制写了端口80，NSURLConnection就是访问不了，其他的网站没问题。麻烦帮忙确认下，服务端做了什么特殊处理么？

这是我在mac运行的日志，libwebsockets这个C库返回了超时。。。
还真没做什么特殊处理，相同的代码，我在本地开服务器，用设备连接本地电脑的3000端口，正常…
我对nodejs不熟悉，^表示往上？看这个应该是比较新的版本。
嗯是的, 1.x.x版本中会找一个最新的
又有一些进展，我用iocat可以正常连接:
iocat -v --socketio http://xxx.com:80/socket.io/1/?EIO=2&transport=polling&b64=true
但是通过ios native连就返回400, 是不是说明还是跟客户端有关系？
哎，自己重新编译websocket库终于找出问题原因了… 这地方前前后后踩了三个坑，其中一个坑之前用lua的时候就遇到过，我还提交了pull request, 直接导致握手触发onConnectionClosed …
现在jsb里面还存在… 好像只有我遇到… 别人都没事…
什么坑？能够分享一下解决方案么？
这个问题我之前其实提交过pull request的, 但是因为不明原因，其他人也没提过, 所以没有合并进去，只能假设大家都没问题了. 我那个修复是有点quick and dirty…
先不多说了，有人遇到了来找我，必定分享.
pull request的链接发一下吧，谢谢。
私信你了
大神求链接!!我现在重连就会一直调用onConnectionClosed …，连接不上服务器
加我QQ吧, 我踩了至少两个坑，要问下你遇到的具体情况… 1676六四零四
cocos creator 1.4.2 使用websocket，也碰到相同问题了。
简单的一个connect ：this._sock = new WebSocket(NetConfig.Server.host + “:” + NetConfig.Server.port);
web测试没问题，在ios模拟器运行就断开连接，求分享解决方案
