python 模拟登陆园子

主要用到了python cookielib,urllib2,urllib这3个模块，python 不亏是具有 先天做 爬虫的特质，废话多说直接上代码

         except Exception,e:
             print e
         self.opener=urllib2.build_opener(urllib2.HTTPCookieProcessor(self.cj))

             L = Login()
             L.setinfo("echosong",'****')
             L.login()
