推荐答案

线索是在返回类型：

AuthorizeCore 返回一个布尔值 - 这是决策的code。这应限于看着用户的身份和检测它们在等等，其作用基本上它应该回答的问题是：

AuthorizeCore returns a boolean - it is decision making code. This should be limited to looking at the user's identity and testing which roles they are in etc. etc. Basically it should answer the question:

我想这个用户继续？

这不应该就在身边执行任何其他活动。

It should not perform any additional activities "on the side".

OnAuthorize 返回void - 这就是你把所有的功能的需要在这一点上发生。例如写入日志，存储在会话等等等等一些数据。

OnAuthorize returns void - this is where you put any functionality that needs to occur at this point. e.g. Write to a log, store some data in session etc etc.
