django接入新浪微博OAuth,djangooauth,最近将网站和新浪微博进行


最近将网站和新浪微博进行了整合,思路很简单,就是将页面内容和新浪微博联系起来,一个独立内容的页面对于一条微博,自然评论系统只需要使用微博的评论即可。然后,用户需要发表评论的话,肯定要接入oauth,不可能让用户登录你的网站来发评论吧?没有谁会将自己的账号和密码告诉你的。查看了新浪微博的授权机制,然后下载了python版的sdk,就可以在django上接入oauth了。

对于oauth很陌生的同学,请先查看OAUTH协议简介其实流程很简单:get_request_token -> create_auth_url ->[user_login: 跳转到新浪登录页面,用户登陆后会跳转回来] -> get_access_token -> done!

在django上结合python版的sdk的具体实现代码,已经有很详细的注释了: oauth_views.py
