[英]Event Listener Called on Every Module Symfony2
嗨,我在symfony2中有一個事件監聽器,我也進行了相應的注冊,它需要在模塊中任何控制器的任何函數調用之前調用。 但這是在調用整個應用程序,我的意思是每個模塊。 但是我只希望有人打開我的模塊時才調用它。
//My Event Listener
namespace Edu\AccountBundle\EventListener;
use Doctrine\ODM\MongoDB\DocumentManager;
use Symfony\Bundle\FrameworkBundle\Routing\Router;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\HttpKernel\Event\FilterControllerEvent;
use Edu\AccountBundle\CommonFunctions\CommonFunctions;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Edu\AccountBundle\Controller\FinancialYearController;
/*
* Class:BeforeControllerListener
* @DESC:its a Listener which will execute at very first of any action of any controller in Account module (Act as a beforeFilter Symfony2)
* @param : @session,@route,@db
* @sunilrawat@indivar.com
* @09-07-2015
*/
class BeforeControllerListener
{
private $session;
private $router;
private $commonFunctions;
public function __construct(Session $session, Router $router, DocumentManager $dm)
{
$this->session = $session;
$this->router = $router;
$this->dm = $dm;
$this->commonFunctions = new CommonFunctions();
}
public function onKernelController(FilterControllerEvent $event)
{
$controller = $event->getController();
if (!is_array($controller)) {
return;
}
if (!$controller[0] instanceof FinancialYearController) {
if ($this->commonFunctions->checkFinancialYear($this->dm) !== 0 ) {
return;
}
$this->session->getFlashBag()->add('error', 'OOPS!, YOU MUST CREATE FINANCIAL YEAR TO MAKE ANY PROCESS IN ACCOUNTS!');
$redirectUrl= $this->router->generate('financialyear');
$event->setController(function() use ($redirectUrl) {
return new RedirectResponse($redirectUrl);
});
}
}
}
//Services.xml
<service id="edu.account.listener" class="Edu\AccountBundle\EventListener\BeforeControllerListener">
<argument type="service" id="session"/>
<argument type="service" id="router"/>
<argument type="service" id="doctrine_mongodb.odm.document_manager"/>
<tag name="kernel.event_listener" event="kernel.controller" method="onKernelController"/>
</service>
現在,當Method完全調用任何控制器的任何操作的核心開始時,但是它正在調用整個項目的每個控制器,相反,我希望它僅在應用程序的“我的特定模塊”中調用。
請指導此中缺少的內容。 提前致謝
為每個控制器調用kernel.controller
事件監聽器是很正常的,重要的是事件監聽器內部的檢查,如果控制器不匹配,則允許您盡早返回。
不過,您的支票確實有誤。 如果控制器不是您期望的類,則可能要返回:
public function onKernelController(FilterControllerEvent $event)
{
$controller = $event->getController();
if (!is_array($controller)) {
return;
}
if (!$controller[0] instanceof FinancialYearController) {
return;
}
if ($this->commonFunctions->checkFinancialYear($this->dm) !== 0 ) {
return;
}
$this->session->getFlashBag()->add('error', 'OOPS!, YOU MUST CREATE FINANCIAL YEAR TO MAKE ANY PROCESS IN ACCOUNTS!');
$redirectUrl= $this->router->generate('financialyear');
$event->setController(function() use ($redirectUrl) {
return new RedirectResponse($redirectUrl);
});
}
}
