将 RedirectToRouteResult 与 Area 一起使用失败

Question

我正在使用自定义过滤器来检查用户对特定操作的访问权限，并且我有一个名为 Admin 的区域。 filter redirect unauthorized user 时，重定向到区域内，而不是路由目录下的视图。
例如，当我现在访问 http://localhost/admin/roles I expect that unauthorized user will be redicreted to http://localhost/authorized but not to http://localhost/admin/authorized 时。
以下是我如何使用过滤器：

   public override void OnAuthorization(AuthorizationContext filterContext)
        {
            DigitalHubOnlineStoreEntities db = new DigitalHubOnlineStoreEntities();
            RbacUser requestingUser = new RbacUser();
            var controllerid = RbacUser.GetControllerId(filterContext.ActionDescriptor.ControllerDescriptor.ControllerName);
            var actionid = RbacUser.GetActionId(filterContext.ActionDescriptor.ActionName, controllerid);          
            if (!requestingUser.GetUserPermission(HttpContext.Current.User.Identity.Name, actionid, controllerid))
            {
                filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary { { "action", "Index" }, { "controller", "Unauthorized" } });
            }
        }

您需要用空字符串指定 Area：

filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary
                       {
                           { "action", "Index" },
                           { "controller", "Unauthorized" },
                           { "Area", String.Empty }
                       });
