1.导入socketserver，ThreadingTCPServer支持多client连接

import socketserver
class 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()
