如何不通过调用官方微博api制作一个第三方微博app---在Android开发模拟登陆微博（weibo.cn）

前段时间对一个第三方微博app---Share的实现原理非常感兴趣，也想自己实现一个自己的第三方微博app。目标有了，那就去查一下微博数据怎么获取吧。原来微博是有开放第三方接口的，只需要申请一个appkey，在Android开发中直接使用微博提供的SDK即可。非常方便，可是。。。这种方便是有代价的，对于一些只是想调用接口玩玩的同学，微博并不会提供大量的微博api调用次数，每天大概只能刷个100次微博就不能再调用了，而且，一些接口也做了很严格的限制，比如发微博要带一个第三方安全链接，比如www.google.com。。。不能查看特定用户的微博等等。。太蛋疼了！于是我想到能不能用模拟登陆的方式直接获取到用户时间线微博，这样就不用调用那烦人的接口了。。。于是在github上找到了fuck-login项目，里面有个模拟登陆微博的python脚本，是通过模拟登陆微博主站 weibo.com再跳转到m.weibo.cn，但实测m.weibo.cn不能爬取微博，要跳转到weibo.cn这个旧网站才行，他的时间线微博id全在返回的html数据里面了。

但毕竟是使用python实现的，于是我按照思路用java代码重新写了一遍，需要用gradle导入 okhttp，persistentcookiejar，scriptenginemanager。

以下是python代码。转载于fuck-login项目点击打开链接

整体的思路是，
1. 先登录到 weibo.com，
2. 然后用 weibo.com 的 cookie 跳转到 m.weibo.cn
3. 保存 cookie 方便以后使用
3. 仅仅在 Python3.4+ 测试通过，低版本没有测试
4. 代码 PEP8 规范

以下是我用java重写的代码，若要获取微博数据，调用init方法完成后，直接用virtuallogin.client访问weibo.cn内的页面即可，可以把cookie保存起来，这样就不用每次都要init了（未实现）。
