如何识别WebSockes

使用Fiddler查看Request Headers

GET /echo/444/6z1x7spy/websocket HTTP/1.1
Origin: http://www.investing.com
Sec-WebSocket-Key: l5fyZFbA5vIGAMpqRdhI/Q==
Connection: Upgrade
Upgrade: websocket
Sec-WebSocket-Version: 13
User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko
Host: stream49.forexpros.com:443
Cache-Control: no-cache

 

使用Fiddler查看Reponse Headers

HTTP/1.1 101 Switching Protocols          ----> 返回101表示服务器端已经理解了客户端的需求，并且客户端需要根据Upgrade中的协议类型，切换为新的协议来完成后续的通信。
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Accept: OE5v65DVpoB/dn2GLCrVo9hqRV8=
EndTime: 16:27:41.872
ReceivedBytes: 125690
SentBytes: 6764

 

然后双击Session，就可以看到WebSockes Tab了
