{{ form_widget(form.recaptcha) }}
</div>
<div class="form-actions">

推荐答案
您可以在优先级为9的 KernelEvents :: REQUEST
上添加事件订阅者,因为类 Symfony \ Bundle \ SecurityBundle \ Debug\ TraceableFirewallListener
(负责为symfony防火墙注册事件)的优先级为8.
You can add event subscriber on KernelEvents::REQUEST
with priority 9. because class Symfony\Bundle\SecurityBundle\Debug\TraceableFirewallListener
(responsible for registering the events for symfony firewall) has priority 8.
这是您的活动订阅者:
class LoginSubscriber implements EventSubscriberInterface
{
/**
* @param \Symfony\Component\HttpKernel\Event\GetResponseEvent $event
*/
public function onKernelRequest(GetResponseEvent $event)
{
if ('LOGIN_ROUTE_NAME' !== $event->getRequest()->attributes->get('_route')) {
return;
}
// get recaptcha from request and validate it.if you want to prevent request to call next event, just set response for event. $event->setResponse($response)
}
public static function getSubscribedEvents()
{
return [
KernelEvents::REQUEST => ['onKernelRequest', 9]
];
}
}
