python模拟浏览器登陆淘宝(设置代理、输入验证码)

终于实现了登陆淘宝,这个验证码机制困惑了我好几天啊。

代码中验证码提供有两种方式,第一种通过webbrowser的open直接在浏览器中打开含有验证码的图片,第二种就是将其以jepg格式存在

C:\\Users\\Administrator\\Desktop\\checkcode.jepg。你可以根据自己主机的用户名更改路径。同时这个代码必须先指定用户名和账号也

可以实时输入账号的密码,小小修改一下代码就可以。

显示根.据httpfox分析网页数据,之后再使用正则扣除你想要的数据,将其显示出来。过几天可能会写一个从淘宝上抓取信息的爬虫,现在

还没有使用各种爬虫框架,基本都是使用urllib、urllib2等比较基础的包,过一阶段可能会学习到框架,我也只是一个菜鸟,一个想要飞的

更高的菜鸟罢了,代码里我写了比较详细的注释,采集软件,基本逻辑就是初始化设置cookie等->发送post数据从返回信息中抓取验证码->再次发送

携带验证码的post数据->从返回信息中提取登陆状态。
