php – 在symfony中实现用户活动2

跟踪用户请求(也可能是他们的活动)的好方法是收听kernel.request事件：

听众类：

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/scheR_428_11845@a/Dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLscheR_428_11845@a-instance"
    xsi:scheR_428_11845@aLOCATIOn="http://symfony.com/scheR_428_11845@a/Dic/services http://symfony.com/scheR_428_11845@a/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>
