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
