開(kāi)發(fā)簡(jiǎn)單的FTP：

1. 用戶登陸

2. 上傳/下載文件

3. 不同用戶家目錄不同

4. 查看當(dāng)前目錄下文件

5. 充分使用面向?qū)ο笾R(shí)

1、目錄結(jié)構(gòu)
zuoye-ftp
├── chenliang #用戶chenliang的FTP根目錄
├── download #所有用戶下載的時(shí)候默認(rèn)文件路徑
├── lw #用戶lw的FTP根目錄
├── lzd #用戶lzd的FTP根目錄
├── wangjun #用戶wangjun的FTP根目錄
├── wdl #用戶wdl的FTP根目錄
├── xueli #用戶xueli的FTP根目錄
├── create-users.py #創(chuàng)建用戶專(zhuān)用py文件
├── ros.zip #模擬上下載的測(cè)試文件ros.zip
├── socket_client.py #客戶端文件
├── socket_server.py #服務(wù)端文件
├── user_data.bak #shelve文件
├── user_data.dat #shelve文件
└── user_data.dir #shelve文件

2、創(chuàng)建用戶運(yùn)行create-users.py，默認(rèn)帳號(hào)密碼是一致的。已有用戶chenliang,lw,lzd,wangjun,wdl,xueli
3、創(chuàng)建的用戶，在執(zhí)行服務(wù)端的時(shí)候，自動(dòng)會(huì)生成一個(gè)自己用戶的FTP根目錄，同時(shí)便于測(cè)試會(huì)復(fù)制ROS.zip到自己根目錄
4、先運(yùn)行socket_server.py，默認(rèn)socket的服務(wù)端端口號(hào)為6969
5、再運(yùn)行socket_client.py
