Python使用urllib2模块抓取HTML页面资源的实例分享
先把要抓取的网络地址列在单独的list文件中

然后我们来看程序操作，代码如下：
#!/usr/bin/python
import os
import sys
import urllib2
import re
def Cdown_data(fileurl, fpath, dpath):
if not os.path.exists(dpath):
os.makedirs(dpath)
try:
getfile = urllib2.urlopen(fileurl)
data = getfile.read()
f = open(fpath, 'w')
f.write(data)
f.close()
except:
print
with open('u1.list') as lines:
for line in lines:
URI = line.strip()
if '?' and '%' in URI:
continue
elif URI.count('/') == 2:
continue
elif URI.count('/') > 2:
#print URI,URI.count('/')
try:
dirpath = URI.rpartition('/')[0].split('//')[1]
#filepath = URI.split('//')[1].split('/')[1]
filepath = URI.split('//')[1]
if filepath:
print URI,filepath,dirpath
Cdown_data(URI, filepath, dirpath)
except:
print URI,'error'
