在symfony 2中实现用户活动

跟踪用户请求(可能还有他们的活动)的好方法是监听内核。请求事件:

侦听器类:

namespace Acme'YourBundle'EventListener;
use Symfony'Component'HttpKernel'Event'GetResponseEvent;
use Symfony'Component'HttpFoundation'Request;
use Symfony'Component'DependencyInjection'ContainerInterface;
class RequestListener
{
    /**
     * Container
     *
     * @var ContainerInterface
     */
    protected $container;
    /**
     * Listener constructor
     *
     * @param ContainerInterface $container
     */
    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }
    /**
     * kernel.request Event
     *
     * @param GetResponseEvent $event
     */
    public function onKernelRequest(GetResponseEvent $event)
    {
        $request  = $event->getRequest();
        // Here you can intercept all HTTP requests, and through $container get access to user information
    }
}

监听器的配置:

<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
    <parameters>
        <parameter key="acme.request_listener.class">Acme'YourBundle'EventListener'RequestListener</parameter>
    </parameters>
    <services>
        <service id="acme.request_listener" class="%acme.request_listener.class%">
            <tag name="kernel.event_listener" event="kernel.request" method="onKernelRequest" />
            <argument type="service" id="service_container" />
        </service>
    </services>
</container>

public function onKernelController(FilterControllerEvent $event)
{
    $controller = $event->getController();
    if ($controller[0] instanceof Controller  and (!strpos( get_class($controller[0]), 'App'FrontendBundle')===false) ) {
  }
}
