Question

我需要在每次浏览之前检查是否设置了某个会话。如果设置了会话，那么将允许用户访问他/她期望的页面。否则将他重定向到会话设置控制器＆amp;行动。为了摇晃我做了下面的任务。但我可以找到从过滤器重定向的方法。从自定义过滤器返回false时，它将重定向到Account Controller。我将非常感谢能帮助我的人。
在我的Global.asax.cs中，我对此进行了编码：

 protected void Application_Start()
 {
     ......
     ......
     RegisterGlobalFilters(GlobalFilters.Filters);
 }

 public static void RegisterGlobalFilters(GlobalFilterCollection filters)
 { 
     filters.Add(new CustomFilters()); 
 }

然后我在我的Filter / CustomFilters.cs目录中添加了下面的代码。

[AttributeUsage(AttributeTargets.Assembly|AttributeTargets.Class| AttributeTargets.Method)]
public class CustomFilters : AuthorizeAttribute
{
    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        if (httpContext.Session["HamdunSoft"] == "HamdunSoft")
        {
            return true;
        }
        else
        {
          return false; //I need to redirect to my custom Controller/Action. But from here
                         it is redirecting  Account Controller default.
        }
    }
}

您还需要覆盖HandleUnauthorizedRequest功能，以便您可以重定向到所需的位置：

protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        if(filterContext.HttpContext.User.Identity.IsAuthenticated)
        {
            if (httpContext.Session["HamdunSoft"] != "HamdunSoft")
            {
                filterContext.Result = new RedirectToRouteResult(new
                RouteValueDictionary(new{ controller = "YourCustomController", action = "YourCustomAction" }));
            }
            else
            {
                base.HandleUnauthorizedRequest(filterContext);
            }
        }
        else
        {
            filterContext.Result = new RedirectToRouteResult(new
            RouteValueDictionary(new{ controller = "Error", action = "AccessDenied" }));
        }
    }

默认情况下从ASP MVC过滤器返回false重定向到帐户控制器
