BeforeRequestTokenProcessedEvent
New in version 12.1
The event
\TYPO3\
allows to intercept or adjust a request token
during active user authentication process.
Example
The event can be used to generate the request token individually. This can be the case when you are not using a login callback and have not the possibility to submit a request token:
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Authentication\EventListener;
use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Core\Authentication\Event\BeforeRequestTokenProcessedEvent;
use TYPO3\CMS\Core\Security\RequestToken;
#[AsEventListener(
identifier: 'my-extension/process-request-token-listener',
)]
final readonly class MyEventListener
{
public function __invoke(BeforeRequestTokenProcessedEvent $event): void
{
$user = $event->getUser();
$requestToken = $event->getRequestToken();
// fine, there is a valid request token
if ($requestToken instanceof RequestToken) {
return;
}
// Validate individual requirements/checks
// ...
$event->setRequestToken(
RequestToken::create('core/user-auth/' . strtolower($user->loginType)),
);
}
}
New in version 13.0
The PHP attribute
\TYPO3\ has been
introduced to tag a PHP class as an event listener. Alternatively, or if you
need to be compatible with older TYPO3 versions, you can also register an
event listener via the Configuration/Services.yaml file. Switch to
an older version of this page for an example or have a look at the section
Implementing an event listener in your extension.
