FTP服务器端

 import FtpClientClass as fcc
 import os
 FtpClient = fcc.MyClient()
 FtpClient.ConnetService()
 while True:
     choice = input(">>>:")
     if not choice : continue

         print("上传完成")

FTP客户端

 {"AFType":"AF_INET","KIND":"SOCK_STREAM","IPaddress":"127.0.0.1","Port":9527,"MaxLinks":5}

服务器配置文件

 {"AFType":"AF_INET","KIND":"SOCK_STREAM","IPaddress":"127.0.0.1","Port":9527}

客户端配置文件

熬到现在头脑已经不清醒了,基本实现上传功能,未完待续

BUG太多,明天再说!

睡觉!
