python中使用urllib2获取http请求状态码的代码例子

采集内容常需要得到网页返回的验证码做进一步处理

下面代码是用python写的用来获取网页http状态码的脚本

#!/usr/bin/python
# -*- coding: utf-8 -*-
#encoding=utf-8
#Filename:states_code.py
 
import urllib2
 
url = 'http://www.jb51.net/'
response = None
try:
  response = urllib2.urlopen(url,timeout=5)
except urllib2.URLError as e:
  if hasattr(e,'code'):
    print 'Error code:',e.code
  elif hasattr(e,'reason'):
    print 'Reason:',e.reason
finally:
  if response:
    response.close()
