python實現儲存網頁到本地樣本

學習python樣本：實現儲存網頁到本地

複製代碼 代碼如下:

#coding=utf-8
__auther__ = 'xianbao'
import urllib
import os
def reporthook(blocks_read, block_size, total_size):
if not blocks_read:
print '開啟串連'
return
if total_size < 0:
print "%d正在讀取(%dbytes完成)"%(blocks_read, blocks_read * block_size)
else:
amout_read = block_size * blocks_read
print '%d正在讀取，%d/%d'%(blocks_read, amout_read, total_size)
return

try:
filename, msg = urllib.urlretrieve('http://www.jb51.net/', reporthook=reporthook)
print
print '檔案是：', filename
print '標頭檔是'
print msg
print '刪除前的檔案地址：', os.path.exists(filename)

finally:
urllib.urlcleanup()

print '檔案依然存在：', os.path.exists(filename)
