Login EventListener not firing on production side

问题

I have an event listener that should fire when a user logs in in my Symfony setup.

I have the following in my services.yml

...
d_user.login_listener:
    class: D\UserBundle\EventListener\LoginListener
    arguments: []
    tags:
        - { name: 'kernel.event_subscriber', event: 'security.interactive_login' }

and in my login listener I simply have this:

<?php

namespace D\UserBundle\EventListener;

use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class LoginListener implements EventSubscriberInterface
{
    public function onSecurityInteractiveLogin(InteractiveLoginEvent $event)
    {
        echo 'user logged in';
    }

    public static function getSubscribedEvents()
    {
        return array(
            // must be registered before the default Locale listener
            'security.interactive_login' => array(array('onSecurityInteractiveLogin', 18))
        );
    }
}

On my dev server I correctly see the text "user logged in" before redirection, but on my production server it just logs in without the event firing. I'm modifying this later to set a session var on user login. I just need to get the method called.

Any advice? I've tried clearing the cache for prod and dev on my production environment, but that didn't help.

Debugging with echo is discouraged. If you want an output, use the logger!

namespace D\UserBundle\EventListener;
use Psr\Log\LoggerInterface;
use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class LoginListener implements EventSubscriberInterface
{
    private $logger;
    private $router;

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

    public function onSecurityInteractiveLogin(InteractiveLoginEvent $event)
    {
        $this->logger->info('user logged in');
    }

    public static function getSubscribedEvents()
    {
        return array(
            // must be registered before the default Locale listener
            'security.interactive_login' => array(array('onSecurityInteractiveLogin', 18))
        );
    }
}

and inject the logger in your service defintion, preferrable with a nice channel name:

d_user.login_listener:
    class: D\UserBundle\EventListener\LoginListener
    arguments: [@logger]
    tags:
        - { name: 'kernel.event_subscriber', event: 'security.interactive_login' }
        - { name: monolog.logger, channel: d_user }
