Python 基于Python实现Ftp文件上传,下载

基于Python实现Ftp文件上传,下载

 

by:授客 QQ1033553122

测试环境:

Ftp客户端:Windows平台

Ftp服务器:Linux平台

Python版本:Python 2.7.6

 

实现功能:

支持FTP文件上传、下载,可以上传目录(分区除外),也可以上传单个文件;可以下载整个目录(/根目录除外),也可以下载单个文件

 

实践代码:

#!/usr/bin/env python
# -*- coding:utf-8 -*-

if __name__ == '__main__':

    # ftp.download_dir('E:/', '/home/testacc')
    ftp.download_file('E:\\', '/home/testacc/testfile')
    ftp.quit()
 
ftp.conf配置如下:
[FTP]
ftp_host = 192.168.1.103
ftp_port = 21
ftp_user = testacc
ftp_passwd = testacc
