python模拟登陆新浪微博 并 关注好友 刷粉丝（rsa算法，2013年7月26日测试成功）

登陆新浪微博的代码已上传至https://github.com/zsrem/python-weibo-login

我的个人主页：郑翊 http://justinzheng.sinaapp.com/

最近完成的页面： 中国搜索-地方 http://local.chinaso.com/

上一篇博客发了之后，收到很多人回信，还是比较开心的。

可惜发了不久，新浪微博改版，以前的登陆方式不好使了。

虽然有人询问新的登陆方法，但由于一直没时间，所以一直没管。

最近找完工作后空闲了，于是重新研究了一下新的登陆方式，写成了代码如下。

并且，其中附加了关注功能，可以方便大家用来刷粉丝。

觉得好用的同时别忘了关注一下我的新浪微博

http://weibo.com/u/1682175375

运行的时候把这句改成自己的账户名和密码即可

weibo = WeiboLogin('name', 'password')

需要额外安装rsa模块

如果不会下载rsa模块，也可去下面地址下载完整代码。
