.net core 過濾器中AuthorizationFilterContext如何獲取訪問的控制器名稱和方法

   public class AuthenFilterAttribute : IAuthorizationFilter
   {
       //每個action執行之前都會進入這個方法
       public void OnAuthorization(AuthorizationFilterContext context)
       {

                var mvcContext = context;
                var descriptor = mvcContext?.ActionDescriptor as ControllerActionDescriptor;
                if (descriptor != null)
                {
                    var actionName = descriptor.ActionName;
                    var ctrlName = descriptor.ControllerName;
                }
        }
    }
