Question

我尝试了两种方式:反应(Redirect())无所作为,并在基地主计长内部提出新的方法,以恢复行动,并返回“Redirect ToAction(RedirectToAction)(两者兼有)。

我怎么能够从“行动执行”方法转向?

Answer 1

 public override void OnActionExecuting(ActionExecutingContext filterContext)
 {
    ...
    if (needToRedirect)
    {
       ...
       filterContext.Result = new RedirectResult(url);
       return;
    }
    ...
 }

Answer 2

也可以这样做:

filterContext.Result = new RedirectToRouteResult(
    new RouteValueDictionary
    {
        {"controller", "Home"},
        {"action", "Index"}
    }
);

建立单独的班级,

    public class RedirectingAction : ActionFilterAttribute
    {
      public override void OnActionExecuting(ActionExecutingContext context)
      {
        base.OnActionExecuting(context);

        if (CheckUrCondition)
        {
            context.Result = new RedirectToRouteResult(new RouteValueDictionary(new
            {
                controller = "Home",
                action = "Index"
            }));
        }
      }
   }

Then, When you create a controller, call this annotation as

[RedirectingAction]
public class TestController : Controller
{
    public ActionResult Index()
    {
        return View();
    }
}

如果再定向控制器继承同一条<代码> 底仓如果我们凌驾于<>关于行动执行<>的守则>方法之上,则会造成休养假。假设我们将其转用于记录账户控制员的行动,则日志行动将称作<>关于行动执行方法的代码,并再次转向同一日志行动。

...... 因此,我们应当在<关于行动执行的代码上进行核对,以检查请求是否由同一控制人提出,如果这样做的话,不会再次将请求重新定位为标志。这部法律是:

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
   try
   {
      // some condition ...
   }
   catch
   {
      if (filterContext.Controller.GetType() != typeof(AccountController))
      {
         filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary {
              { "controller", "Account" }, 
              { "action", "Login" } 
         });
      }
   }
}
