重定向用户以在视图助手中路由

In my View Helper, I need to redirect the user to route. Do you know how I can do that ?

My View helper :

namespace MyProject\View\Helper;

use Zend\View\Helper\AbstractHelper;
use Zend\Session\Container;
use Zend\Http\Response;


class Connected extends AbstractHelper
{

  public function __invoke()
  {

    $Session = new Container('base');
    $Response = new Response;

    if(!$Session->offsetExists('user_id'))
      return $Response->toRoute('auth');
  }

}

The php error:

PHP Fatal error:  Call to undefined method Zend\\Http\\Response::toRoute() in /SRV/www/firewall/ZendFramework/module/MyProject/src/MyProject/View/Helper/Connected.php on line 19

Thanks you for you help all ! Best regards,

Thanks all, but I have solved my problem.

I know is not the better solution but that work fine:

class Connected extends AbstractHelper
{

  private $global;

  public function __construct($global)
  {
    $this->global = $global;
  }

  public function __invoke()
  {
    # Call the container
    $Session = new Container('base');

    # If the session doesn't exist, we redirect the user
    if(!$Session->offsetExists('user_id'))
      header('Location: ' . $this->global['global']['url']);

  }

}

Thanks you all for your help !
