为什么在asp.net mvc中会话超时后jquery ajax调用失败？

当我的会话变量中有一个值时，我的ajax调用可以正常工作...但是当会话超时时，它似乎无法返回空json结果...

public JsonResult GetClients(int currentPage, int pageSize)
        {
            if (Session["userId"]!=null)
            {
                var clients = clirep.FindAllClients(Convert.ToInt32(Session["userId"])).AsQueryable();
                var count = clients.Count();
                var results = new PagedList<ClientBO>(clients, currentPage - 1, pageSize);
                var genericResult = new { Count = count, Results = results ,isRedirect=false};
                return Json(genericResult);
            }
            else
            {
                var genericResult = new {redirectUrl = Url.Action("Create", "Registration"), isRedirect = true };
                return Json(genericResult);
            }

        }

但是其他部分似乎不起作用... 。

   success: function(data) {
       alert(data.Results);
        if (data.isRedirect) {
            window.location.href = data.redirectUrl;
        }
   }

编辑：

我的global.asax有这个，

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                "Clients",                                             
                "Clients/{action}/{id}",                          
                new { controller = "Clients", action = "Index", id = "" }  
            );

            routes.MapRoute(
               "Registrations",                                              
               "{controller}/{action}/{id}",                          
               new { controller = "Registration", action = "Create", id = "" } 
           );
        }

when there is a value in my session variable my ajax calls work properly... But when a session is timedout it doesn't seem to work returning empty json result....

public JsonResult GetClients(int currentPage, int pageSize)
        {
            if (Session["userId"]!=null)
            {
                var clients = clirep.FindAllClients(Convert.ToInt32(Session["userId"])).AsQueryable();
                var count = clients.Count();
                var results = new PagedList<ClientBO>(clients, currentPage - 1, pageSize);
                var genericResult = new { Count = count, Results = results ,isRedirect=false};
                return Json(genericResult);
            }
            else
            {
                var genericResult = new {redirectUrl = Url.Action("Create", "Registration"), isRedirect = true };
                return Json(genericResult);
            }

        }

However else part does'nt seem to work....

   success: function(data) {
       alert(data.Results);
        if (data.isRedirect) {
            window.location.href = data.redirectUrl;
        }
   }

EDIT:

My global.asax has this,

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                "Clients",                                             
                "Clients/{action}/{id}",                          
                new { controller = "Clients", action = "Index", id = "" }  
            );

            routes.MapRoute(
               "Registrations",                                              
               "{controller}/{action}/{id}",                          
               new { controller = "Registration", action = "Create", id = "" } 
           );
        }

尝试重定向无论响应是什么：

success: function(data) {
  location = 'http://www.google.ca';
}

如果重定向，您可以消除这种可能性

然后尝试显式比较变量并暂时保持 URL 硬编码：

success: function(data) {
    if (data.isRedirect && data.isRedirect === true) {
        alert('must redirect to ' + data.redirectUrl);
        location = 'http://www.google.ca';
    }
    else
    {
        alert('not redirecting ' + );
    }
}

您还可以查看 data.redirectUrl 返回

Comke之后回到我身边...

Try to redirect whatever the response is:

success: function(data) {
  location = 'http://www.google.ca';
}

if that redirects, you can eliminate that possibility

Then try to explicitely compare the variable and keep the URL hardcoded for the moment:

success: function(data) {
    if (data.isRedirect && data.isRedirect === true) {
        alert('must redirect to ' + data.redirectUrl);
        location = 'http://www.google.ca';
    }
    else
    {
        alert('not redirecting ' + );
    }
}

You can also see what data.redirectUrl returns

Comke back to me after that...
