python--socketserver

用socketserver，实现多人聊天的功能

    server=socketserver.ThreadingTCPServer(('127.0.0.1',8080),MyServer)
    server.serve_forever()


import socketserver

    def handle(self):    #必须有这个方法名 ，因为源码中会调用这个方法
        while True:      #self.request 类似于conn
            msg=self.request.recv(1024).decode('utf-8')
