这可能是一个熟悉的啜泣故事。但是那里有这么多,而且我是一个n00b,我找不到答案,所以如果你能帮助我,我希望你能帮助我。
所以,我正在使用 lemmingzshadow 的 phpwebsocket(如果你不熟悉,谷歌很容易提出这个问题)。据我所知,他发布的版本有一个错误,它不符合 Chrome 20.+ 现在使用的标准。它与握手和安全密钥有关,但这就是我坚持的地方。我知道我需要根据其他问题提供以下内容,希望您能帮助我理解并解决此问题:
Chrome 收到的标头是(已编辑;我显然将消息发布到服务器两次。):
HTTP/1.1 101 Switching Protocols
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Accept: aWXrpLOnEm15mE8+w1zG05ad01k=
Sec-WebSocket-Protocol: QuatroDuo
我的服务器收到的标头是:
Upgrade: websocket
Connection: Upgrade
Host: gumonshoe.net:8000
Origin: http://gumonshoe.net
Sec-WebSocket-Key: v3+iw0U78qkwZnp+RWTu3A
Sec-WebSocket-Version: 13
Sec-WebSocket-Extensions: x-webkit-deflate-frame
我不认为cookies是必要的,如果我错了,请纠正我。
我讨厌做下一部分,但我认为将其全部粘贴总比什么都不做并且需要稍后再回来要好。这是读取和解释握手并发送新握手的代码部分。
有帮助:

收到以下错误,
Error during WebSocket handshake: Sec-WebSocket-Protocol mismatch
由于我在此级别的服务器调试方面基本上没有经验,因此将不胜感激提供比将我链接到文档/规范更详细的答案。
