本文实例讲述了Python脚本实现虾米网签到功能的方法。分享给大家供大家参考，具体如下：

概述

这个脚本完成了自动登录虾米网、签到的功能。

大致要用到urllib、urllib2、cookielib这几个模块。其实就是用python实现向指定的url去post数据。

至于我怎么知道在浏览器里面登录和签到时浏览器都向服务器post了什么数据的问题，可以用强大的chrome：F12->Network里面可以看得到。有的服务器登录成功后会让客户端浏览器跳转或者立即刷新一次页面等等，会把登录时向服务器post的数据刷没掉，那么就要用到强大的抓包软件——WireShark来分析。比如用chrome：

然后就可以写了，构造Request Headers和要Post的Data（就是Chrome里的Form Data），ID和Pwd是明文传输，呵呵。

代码

    self.cookie = cookielib.LWPCookieJar()

    postdata = urllib.urlencode(postdata)
    print 'Logining...'
    req = urllib2.Request(url='http://www.xiami.com/member/login', data=postdata, headers=self.login_header)
    result = urllib2.urlopen(req).read()
    self.cookie.save(self.cookieFile)
    result = str(result).decode('utf-8').encode('gbk')
    if 'Email 或者密码错误' in result:
      print 'Login failed due to Email or Password error...'
      sys.exit()
    else :
      print 'Login successfully!'
  def signIn(self):
    postdata = {}
    postdata = urllib.urlencode(postdata)
    print 'signing...'
    req = urllib2.Request(url='http://www.xiami.com/task/signin', data=postdata, headers=self.signin_header)
    result = urllib2.urlopen(req).read()
    result = str(result).decode('utf-8').encode('gbk')
    self.cookie.save(self.cookieFile)
    try:
      result = int(result)
    except ValueError:
      print 'signing failed...'
      sys.exit()
    except:
      print 'signing failed due to unknown reasons ...'
      sys.exit()
    print 'signing successfully!'
    print self.email,'have signed', result, 'days continuously...'
if __name__ == '__main__':
  user = LoginXiami('你的登录邮箱', '你的密码')
  user.login()
  user.signIn()

然后运行一下脚本就可以登录、签到了。
