Python 实现的 WebSocket 的 Client 和 Server 端，实例可查看https://github.com/Lawouach/WebSocket-for-Python/tree/master/example

在这里插入图片描述
之前曾有php版的websocket封装包，见Websocket——php实战，最近使用python做一些功能，需要用到对websocket的操作，因此，参照之前的实现，实现了这个python版本。源码见https://github.com/OshynSong/wspy。
整体实现起来，需要在建立socket监听端口，这需要用到socket标准库模块；之后，需要对对网络字节流进行操作，这个方面python有struct标准库模块，这个非常好用；另外涉及到加密解密操作，还有hashlib模块和sha模块等使用。特别在此总结一下，目的主要是
