1.导入socketserver，ThreadingTCPServer支持多client连接

import socketserverclass Mysocket(socketserver.BaseRequestHandler):        def handle(self):                    while True:                            try:                                    pass                            except ConnectionResetError as e:                                    print(e)if __name__=="__main__":    Host,port='localhost',8989    server=socketserver.ThreadingTCPServer((Host, port), Mysocket)    server.serve_forever()
