Symfony requestStack-＆gt; getCurrentRequest（）返回空的post数组

Question

尝试在doctrine listener中获取POST参数。但是，获得一个空数组。试图将请求推送到控制器中的requeststack。但是，仍然是空洞的。

class OrderListener
{
    private $requestStack;

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

    public function postPersist(LifecycleEventArgs $args)
    {
        $entity = $this->getObject();
        if ($entity instanceof Order) {
            $request = $this->requestStack->getCurrentRequest();

            $this->handleEvent($entity, $args->getEntityManager());
        }
    }

    public function handleEvent(Order $order, EntityManagerInterface $em)
    {
       // here $request->request->all() is empty
       $request = $this->requestStack->getCurrentRequest();
       $transaction = new Transaction();
       $transaction->setOrder($order);
       $transaction->setRemoteId($request->request->get('stripeInvoiceId'));
       ...
    }
}

所以，json_decode($request->getContent(), true)给了我正确的参数。返回一组后期数据。奇怪的是$request->request->all()也应该有效。
