服务端：

                f.writelines((str(datetime.datetime.today()).encode('UTF-8'),
                              ('-客户端地址:' + addr[0] + '-发送内容:' + cval).encode('UTF-8'),
                              (('-主机回复：%s' % cval) + os.linesep).encode('UTF-8')))

    # 代表通讯的socket和客户端地址
    vala, addr = st.accept()
    # 保存对应的sockt到列表中
    client_list.append(vala)
    print(addr)
    with open('txtinfo.txt', 'ab', True) as f:
        f.write((str(datetime.datetime.today()) + '-客户端地址:' + str(addr[0]) + os.linesep).encode('UTF-8'))
        # 为客户端对应的sockt启动对应的线程
    threading.Thread(target=server_target, args=(vala, addr)).start()

 

 

客户端：

通过threading.Thread创建线程
