我确实在libevent中实现了websocket服务器,虽然我对Chrome或Firefox没有任何问题,但是IE10我甚至无法建立连接。

握手:

IE10 Request:
GET /echo HTTP/1.1
Origin: 95.115.195.4
Sec-WebSocket-Key: rgPWUlUtk+h3CPWqk99OtA==
Connection: Upgrade
Upgrade: Websocket
Sec-WebSocket-Version: 8
User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)
Host: 95.115.195.4:5555
Cache-Control: no-cache

Server Response:
HTTP/1.1 101 Switching Protocols
Upgrade: Websocket
Connection: Upgrade
Sec-WebSocket-Accept: jGmgQ/jOvew8MU9o3bbqPG9PHlY=
Sec-WebSocket-Protocol: chat

IE10调试器说: SCRIPT12152:WebSocket错误:HTTP响应不正确。状态代码101

任何人都知道我做错了什么?

客户端未发送子协议列表,但您的服务器已将“聊天”作为子协议值发回。根据{{​​3}}第19页(4.1节客户要求的末尾):

6.  If the response includes a |Sec-WebSocket-Protocol| header field
   and this header field indicates the use of a subprotocol that was
   not present in the client's handshake (the server has indicated a
   subprotocol not requested by the client), the client MUST _Fail
   the WebSocket Connection_.

如果客户端向服务器发送了“Sec-WebSocket-Protocol:SUBPROTOCOL,...”标头,则服务器应仅将“Sec-WebSocket-Protocol:SUBPROTOCOL”标头发送回客户端。请注意,客户端可以发送子协议列表,如果是,则服务器必须从列表中选择一个以进行响应。

Firefox和Chrome可能过于宽松而且不符合规范的当前版本。
