python3发送需要双向认证的wss请求

python3发送需要双向认证的wss请求

websocket链接python有很多封装好的库：websocket-client、websockets、aiowebsocket 这里用的websokets

此次接口要求：1、需要双向认证 2、wss协议 3、发送数据和接受数据都需要序列化和反序列化（probuff）

# 服务端声明CLIENT_AUTH

#Purpose.CLIENT_AUTH该值表示该上下文可用于对Web客户端进行身份验证（因此，它将用于创建服务器端套接字），carfile服务端证书
ssl_context = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH,cafile="D://my_project//Ajcloud//ca.crt")
# certfile和keyfile参数为指定包含证书被用来识别连接的本地端可选的文件，客户端证书
