Symfony 5 (Bolt 4) 中的用户列表
List of users in Symfony 5 (Bolt 4)
我正在使用基于 Symfony 5 的 Bolt 4 CMS。在我编写的控制器中,我想列出我数据库中的所有用户,以检索他们的电子邮件地址并向他们发送电子邮件。现在我只是想从用户名中检索电子邮件地址。
在此示例中 https://symfony.com/doc/current/security/user_provider.html,它说明了如何创建自己的 class 来处理来自数据库的用户:
// src/Repository/UserRepository.php
namespace App\Repository;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Symfony\Bridge\Doctrine\Security\User\UserLoaderInterface;
class UserRepository extends ServiceEntityRepository implements UserLoaderInterface
{
// ...
public function loadUserByUsername(string $usernameOrEmail)
{
$entityManager = $this->getEntityManager();
return $entityManager->createQuery(
'SELECT u
FROM App\Entity\User u
WHERE u.username = :query
OR u.email = :query'
)
->setParameter('query', $usernameOrEmail)
->getOneOrNullResult();
}
}
在我的自定义控制器中,我调用这个 class 和函数:
// src/Controller/LalalanEventController.php
namespace App\Controller;
use Symfony\Component\Mailer\MailerInterface;
use Symfony\Component\Mime\Email;
use App\Repository\LalalanUserManager;
class LalalanEventController extends AbstractController
{
/**
* @Route("/new_event_email")
*/
private function sendEmail(MailerInterface $mailer)
{
$userManager = new LalalanUserManager();
$email = (new Email())
->from('aaa.bbb@ccc.com')
->to($userManager('nullname')->email)
->subject('Nice title')
->text('Sending emails is fun again!')
->html('<p>See Twig integration for better HTML integration!</p>');
$mailer->send($email);
}
}
不幸的是,在示例中,class 扩展自 ServiceEntityRepository
,这需要 ManagerRegistry
作为构造函数。有谁知道我可以改变什么来解决这个问题?
提前致谢!
如文档中所述,
User providers are PHP classes related to Symfony Security that have two jobs:
- Reload the User from the Session
- Load the User for some Feature
因此,如果您只想获取用户列表,您只需像这样获取 UserRepository
:
/**
* @Route("/new_event_email")
*/
private function sendEmail(MailerInterface $mailer)
{
$userRepository = $this->getDoctrine()->getRepository(User::class);
$users = $userRepository->findAll();
// Here you loop over the users
foreach($users as $user) {
/// Send email
}
}
