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 = '//www.jb51.net/'response = Nonetry:  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.reasonfinally:  if response:    response.close()
