How Django accesses Sina Weibo's OAuth

This article is an example of how Django accesses Sina Weibo oauth. Share to everyone for your reference. The specific analysis is as follows:

The recent integration of the site and Sina Weibo, the idea is simple, is to link the content of the page and Sina Weibo, a separate content page for a micro-blog, the natural comment system only need to use Weibo comments. Then, users need to post a comment, it is necessary to access OAuth, it is not possible for users to log on to your website to comment it? No one will tell you their account number and password. After reviewing the licensing mechanism for Sina Weibo, and then downloading the Python version of the SDK, you can access OAuth on Django.

For students who are unfamiliar with OAuth, please review the OAuth protocol introduction first

In fact, the process is simple:

①getrequesttoken
②createauthurl
③[user_login: Jump to the Sina login page, the user will jump back after landing],
④getaccesstoken
⑤done!

The specific implementation code of the Python version of the SDK on Django has been commented in detail:

The oauth_views.py file is as follows:
