python实现登陆知乎获得个人收藏并保存为word文件

这个程序其实很早之前就完成了,一直没有发出了,趁着最近不是很忙就分享给大家.
使用BeautifulSoup模块和urllib2模块实现,然后保存成word是使用python docx模块的,安装方式网上一搜一大堆,我就不再赘述了.

主要实现的功能是登陆知乎,然后将个人收藏的问题和答案获取到之后保存为word文档,以便没有网络的时候可以查阅.当然,答案中如果有图片的话也是可以获取到的.不过这块还是有点问题的.等以后有时间了在修改修改吧.

还有就是正则,用的简直不要太烂…鄙视下自己…

还有,现在是问题的话所有的答案都会保存下来的.看看有时间修改成只保存第一个答案或者收藏页问题的答案吧.要不然如果收藏的太多了的话保存下来的word会吓你一跳的哦.O(∩_∩)O哈哈~

在登陆的时候可能会需要验证码,如果提示输入验证码的话在程序的文件夹下面就可以看到验证码的图片,照着输入就ok了.
