c# - ASP MVC ActionFilterAttribute OnActionExecuting 未触发

Question

我有 2 个 Controller Home 和

public class HomeController : Controller
    {
    protected override void OnActionExecuting(ActionExecutingContext filterContext)
            {
                // do some irrelevant stuff
                    base.OnActionExecuting(filterContext);           

            }

    public ActionResult Index()
            {            
                    return View();
            }
}

和服务与

public ActionResult Confirm()
            { return RedirectToAction("Index", "Home");}

还有一个 ActionFilterAttribute 和 OnActionExecuting 方法

 public class InvitationModeAttribute : ActionFilterAttribute
    {
     public override void OnActionExecuting(ActionExecutingContext filterContext)
            {
               // do some stuff

                base.OnActionExecuting(filterContext);
            }
}

public class FilterConfig
    {
        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {            
            filters.Add(new InvitationModeAttribute());
        }
    }

当我转到 localhost/Service/Confirm 时，OnActionExecuting 被触发，但是当 RedirectToAction 被调用时，OnActionExecuting 没有被解雇。 我怎样才能在 RedirectToAction 之后捕捉到它？

谢谢

Answer 1

引用this为了更清楚

首先 删除 Controller 级别的 OnActionExecuting 方法

public class HomeController : Controller
{
       [InvitationModeAttribute]
     public ActionResult Index()
     {            
        return View();
     }
 }

第二个 Controller

 public class ServiceController : Controller
 {
   [InvitationModeAttribute]
   public ActionResult Confirm()
   { 
     return RedirectToAction("Index", "Home");
   }
 }

Scope of Action Filters

In addition to marking individual action methods with an action filter, you can mark a controller class as a whole with an action filter. In that case, the filter applies to all action methods of that controller. Additionally, if your controller derives from another controller, the base controller might have its own action-filter attributes. Likewise, if your controller overrides an action method from a base controller, the method might have its own action-filter attributes and those it inherits from the overridden action method. To make it easier to understand how action filters work together, action methods are grouped into scopes. A scope defines where the attribute applies, such as whether it marks a class or a method, and whether it marks a base class or a derived class.
