首页 / 操作系统 / Linux / Python FTP 下载文件 简单示例
简单的FTP下载 ,不加任何异常判断。import osfrom ftplib import FTPftp_addr = "10.10.0.1"f=FTP(ftp_addr)
f.login("anonymous")
f.cwd("apk_download/")
remote_file = "20141223140651.apk"
f.retrbinary("RETR %s" % remote_file, open(remote_file, "wb").write)还有个带 异常处理的版本#! encoding:utf-8
# Filename : ftptestdown.py
#使用ftplib.error_perm函数来打印输出错误信息import ftplib
