python抓取新浪微博,求教!!?

python抓取新浪微博,被挡,用了代理,有10个帐号,10个代理,爬的很慢,大家有什么好的办法,谢谢!!!回复内容:
http://github.com/zhu327/rss 既然你也用python就直接看代码吧爬这里 http://service.weibo.com/widget/widget_blog.php?uid={uid} 替换uid,无需登录,不会被挡
爬手机端http://weibo.cn可以参考下面的代码,来自极客学院,侵删

据说爬手机版会有奇效。
我以前爬过,不知道现在可行不爬他的移动端页面,当时限制比网页端少。爬虫程序部署在google app engine多个节点上跑
新浪有开发者平台,有专门的api接口,用爬虫会被屏蔽
