Python利用pywss库实现Websocket
pywss是一种类似Flask开发的WebSocket-Server服务端框架，适用python3.X
一、安装
pip install pywss
二、使用
from pywss import Pyws, route
@route(/websocket)
def my_websocket(request, data):
print(‘客户端发来数据：%s’ % data)
return data + - data from pywss
if __name__ == __main__:
ws = Pyws(__name__, address=127.0.0.1, port=8888)
ws.serve_forever()
