我希望能够从容器中获取当前登录用户的凭据（电子邮件，密码等）。所以，这就是我所做的：
security.token:
class: Symfony'Component'Security'Core'Authentication'Token'TokenInterface
factory: ["@security.token_storage", "getToken"]
private: true
security.current_user_credentials:
class: Symfony'Component'Security'Core'User'UserInterface
factory: ["@security.token", "getUser"]
security.current_user:
class: AppBundle'Entity'User
factory: ["@security.current_user_credentials", "getUser"]
当我这样做并且我登录时，它工作正常。但是，当我注销时，我得到dev.log

是否可以使security.current_user_credentials和security.current_user可选？此错误是由这些服务引起的吗？
最近我遇到了类似的问题，如果您尝试访问不存在的路由，您可能会看到相同的错误。我正在处理一项任务，我需要在我的服务中掌握登录用户，这就是我实现它的方式
我的services.yml
services:
student_application_subscriber:
class: namespace'YourBundle'EventListener'StudentApplicationSubscriber
arguments:
- @doctrine.orm.entity_manager
- @security.token_storage
- @security.authorization_checker
- @twig
这是我的服务类StudentApplicationSubscriber
namespace yournamespace'YourBundleBundle'EventListener;
use Doctrine'ORM'EntityManager;
use Symfony'Component'EventDispatcher'EventSubscriberInterface;
class StudentApplicationSubscriber implements EventSubscriberInterface
{
protected $em;
protected $twig;
protected $tokenStorage;
protected $authChecker;
function __construct(EntityManager $em, $tokenStorage, $authChecker, $twig)
{
$this->em = $em;
$this->twig = $twig;
$this->tokenStorage = $tokenStorage;
$this->authChecker = $authChecker;
}
public static function getSubscribedEvents()
{
return array(
'kernel.request' => 'onKernelRequest'
);
}
public function onKernelRequest()
{
if (!$token = $this->tokenStorage->getToken()) {
return;
}
$user = $token->getUser();
if (!is_object($user)) {
// there is no user - the user may not be logged in
return;
}
//get details of logged in user
$get_user_details = $this->tokenStorage->getToken()->getUser();
//make sure to pull information when user is logged in
if ($this->authChecker->isGranted('IS_AUTHENTICATED_FULLY')) {
//get user id of logged in user
$userId = $get_user_details->getId();
//perform your logic here
}
}
}
你想实现什么？乍一看，我建议要么有一个内核侦听器来检查是否有用户并执行所需的操作，要么在您的security.current_user_credentials中检查它。
我想，如果您只是传递给您的服务并在该函数中添加以下逻辑，那么它适用于匿名用户和经过身份验证的用户：
function dummyFunction($securityContext)) {
$email = $username = '';
if($securityContext->isGranted('IS_AUTHENTICATED_FULLY')) {
$email = $securityContext->getToken()->getUser()->getEmail();
$username = $securityContext->getToken()->getUser()->getUsername();
}
