本文实例讲述了python实现简单ftp客户端的方法。分享给大家供大家参考。具体实现方法如下:
#!/usr/bin/python # -*- coding: utf-8 -*- import ftplib import os import socket HOST = 'ftp.mozilla.org' DIRN = 'pub/mozilla.org/webtools' FILE = 'bugzilla-3.6.9-to-3.6.10-nodocs.diff.gz' def writedata(data): f = open(FILE,'wb') try: f.write(data) finally: f.close() def main(): try: f = ftplib.FTP(HOST) except (socket.error, socket.gaierror): print 'ERROR:cannot reach " %s"' % HOST return print '***Connected to host "%s"' % HOST try: f.login() except ftplib.error_perm: print 'ERROR: cannot login anonymously' f.quit() return print '*** Logged in as "anonymously"' try: f.cwd(DIRN) except ftplib.error_perm: print 'ERRORL cannot CD to "%s"' % DIRN f.quit() return print '*** Changed to "%s" folder' % DIRN try: #传一个回调函数给retrbinary() 它在每接收一个二进制数据时都会被调用 f.retrbinary('RETR %s' %FILE, writedata) except ftplib.error_perm: print 'ERROR: cannot read file "%s"' %FILE os.unlink(FILE) else: print '*** Downloaded "%s" to CWD' % FILE f.quit() return if __name__ == '__main__': main()
希望本文所述对大家的Python程序设计有所帮助。
