本文实例讲述了python实现的简单FTP上传下载文件的方法。分享给大家供大家参考。具体如下:
python本身自带一个FTP模块,可以实现上传下载的函数功能。
#!/usr/bin/env python # -*- coding: utf-8 -*- from ftplib import FTP def ftp_up(filename = "20120904.rar"): ftp=FTP() ftp.set_debuglevel(2) #打开调试级别2,显示详细信息;0为关闭调试信息 ftp.connect('192.168.0.1','21') #连接 ftp.login('admin','admin') #登录,如果匿名登录则用空串代替即可 #print ftp.getwelcome() #显示ftp服务器欢迎信息 #ftp.cwd('xxx/xxx/') #选择操作目录 bufsize = 1024 #设置缓冲块大小 file_handler = open(filename,'rb') #以读模式在本地打开文件 ftp.storbinary('STOR %s' % os.path.basename(filename),file_handler,bufsize) #上传文件 ftp.set_debuglevel(0) file_handler.close() ftp.quit() print "ftp up OK" def ftp_down(filename = "20120904.rar"): ftp=FTP() ftp.set_debuglevel(2) ftp.connect('192.168.0.1','21') ftp.login('admin','admin') #print ftp.getwelcome() #显示ftp服务器欢迎信息 #ftp.cwd('xxx/xxx/') #选择操作目录 bufsize = 1024 filename = "20120904.rar" file_handler = open(filename,'wb').write #以写模式在本地打开文件 ftp.retrbinary('RETR %s' % os.path.basename(filename),file_handler,bufsize) #接收服务器上文件并写入本地文件 ftp.set_debuglevel(0) file_handler.close() ftp.quit() print "ftp down OK"
