复制代码 代码如下:

#coding=utf-8

__auther__ = 'xianbao'

import urllib

import os

def reporthook(blocks_read, block_size, total_size):

if not blocks_read:

print '打开连接'

return

if total_size < 0:

print "%d正在读取(%dbytes完成)"%(blocks_read, blocks_read * block_size)

else:

amout_read = block_size * blocks_read

print '%d正在读取，%d/%d'%(blocks_read, amout_read, total_size)

return

try:

filename, msg = urllib.urlretrieve('http://www.jb51.net/', reporthook=reporthook)

print

print '文件是：', filename

print '头文件是'

print msg

print '删除前的文件地址：', os.path.exists(filename)

finally:

urllib.urlcleanup()

print '文件依然存在：', os.path.exists(filename)
