What is the most straight forward way to use AuthorizeAttribute and JsonResult together so that when the user is not authorized the application returns a Json error rather than a log in page?
The two things I am currently considering are extending AuthorizeAttribute or just making a new attribute that implements IAuthorizationFilter.
回答1:
Remove the AuthorizeAttribute from your Action.
Then in the first lines of your action, insert this:
if (!User.Identity.IsAuthenticated)
return Json("Need to login");
or return whatever message you want.
