[Question] How to manually generate a refresh token?

[mgluesenkamp]

Hi,

for a special case I need to manually generate an access and a refresh token with the bundle. The reason is very complicated, but I have to automatically generate a user on the first request of a device. So, I have no user and no registration.

I managed to get an access token by the following code, but I don't know how I can get the refresh token. I searched for the methods in the code of the bundle but by now I couldn´t find the right methods.
How can I generate a refresh token manually?

I hope you can help.
Thank you very much!

use Trikoder\Bundle\OAuth2Bundle\League\Entity\AccessToken as AccessTokenEntity;
use Trikoder\Bundle\OAuth2Bundle\League\Entity\Client as ClientEntity;
use Trikoder\Bundle\OAuth2Bundle\League\Entity\Scope as ScopeEntity;
use Trikoder\Bundle\OAuth2Bundle\Model\AccessToken as AccessTokenModel;
use Trikoder\Bundle\OAuth2Bundle\Model\Client as ClientModel;

private function createAuthToken($user, $client = 'apps') {
	$clientModel = $this->em->getRepository(ClientModel::class)->findOneBy(['identifier' => $client]);

	$now = new \DateTimeImmutable();
	$accessTokenTtl = (new \DateTimeImmutable())->add(new \DateInterval(self::ACCESS_TOKEN_TTL));
	$expiresIn = $accessTokenTtl->getTimestamp() - $now->getTimestamp() - 3600;

	$accessTokenModel = new AccessTokenModel(bin2hex(random_bytes(40)), $accessTokenTtl, $clientModel, $user->getEmail(), []);
	$privateKey = new CryptKey($this->privateKey, null, false);

	$clientEntity = new ClientEntity();
	$clientEntity->setIdentifier($accessTokenModel->getClient()->getIdentifier());
	$clientEntity->setRedirectUri(array_map('strval', $accessTokenModel->getClient()->getRedirectUris()));

	$accessTokenEntity = new AccessTokenEntity();
	$accessTokenEntity->setPrivateKey($privateKey);
	$accessTokenEntity->setIdentifier($accessTokenModel->getIdentifier());
	$accessTokenEntity->setExpiryDateTime($accessTokenModel->getExpiry());
	$accessTokenEntity->setClient($clientEntity);
	$accessTokenEntity->setUserIdentifier($accessTokenModel->getUserIdentifier());

	foreach ($accessTokenModel->getScopes() as $scope) {
		$scopeEntity = new ScopeEntity();
		$scopeEntity->setIdentifier((string)$scope);
		$accessTokenEntity->addScope($scopeEntity);
	}

	$this->em->persist($accessTokenModel);

	$response = [
		'token_type' => 'Bearer',
		'expires_in' => $expiresIn,
		'access_token' => $accessTokenEntity->__toString(),
		'refresh_token' => null,
	];

	return $response;
}
