如何检查Twitter OAuth access_token是否仍然有效？
[英]How do I check if a Twitter OAuth access_token is still valid?
问题描述
I'm writing a Django app and I want users to be able to supply their Twitter username and connect their Twitter account with their User in my app. 
我正在编写Django应用，我希望用户能够提供其Twitter用户名，并将其Twitter帐户与我的应用中的User连接。 (I'm not using Twitter to log them into my site; I just want them to connect their Twitter account with their account on my site, and give permissions for certain actions.) （我不是在使用Twitter将他们登录到我的网站；我只是希望他们将其Twitter帐户与他们在我的网站上的帐户相关联，并为某些操作提供权限。）
Assuming I do that successfully, and I get back and store an access_token for the user, what's the best way to subsequently check that the access_token is still valid? 假设我成功完成此操作，然后返回并为用户存储了一个access_token，那么随后检查该access_token仍然有效的最佳方法是什么？ ie, if the user has later revokes access to my service on their Twitter account, I want to be able to check the access_token and, if it's invalid, delete it and prompt the user to re-authenticate. 即，如果用户以后撤消了其Twitter帐户上对我的服务的访问权限，则我希望能够检查access_token，如果无效，则将其删除并提示用户重新进行身份验证。
The Flickr API has flickr.auth.checkToken and I guess I'm looking for the equivalent functionality with the Twitter API. Flickr API具有flickr.auth.checkToken ，我想我正在寻找与Twitter API等效的功能。
