基于MVC控制器的自定义400重定向

你总是可以实现你自己的 authorization attribute :

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class CustomAuthorizeAttribute : AuthorizeAttribute
{
    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        var controllerName = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName;
        var actionName = filterContext.ActionDescriptor.ActionName;
        // TODO: Now that you know the controller name and the action name
        // act accordingly or call the base method
    }
}
