在Symfony 2.8 / 3.0中,如果使用我们新的安全组件,如何在服务中获取当前记录的User
(即FOSUser )对象,而不需要注入整个容器?</ p>
甚至可以用非hacky方式吗?
PS:我们不认为&#34; 将其作为参数传递给服务功能&#34;因为显而易见。另外,很脏。

将security.token_storage
服务注入您的服务,然后使用:
$this->token_storage->getToken()->getUser();
如此处所述:http://symfony.com/doc/current/book/security.html#retrieving-the-user-object和此处:http://symfony.com/doc/current/book/service_container.html#referencing-injecting-services

使用构造函数依赖注入,您可以这样做:
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
class A
{
private $user;
public function __construct(TokenStorageInterface $tokenStorage)
{
$this->user = $tokenStorage->getToken()->getUser();
}
public function foo()
{
dump($this->user);
}
}

版本3.4中的新增功能:Symfony 3.4中引入了Security实用程序类。
use Symfony\Component\Security\Core\Security;
public function indexAction(Security $security)
{
$user = $security->getUser();
}

来自Symfony 3.3
,<仅来自控制器的 ,根据此博文:https://symfony.com/blog/new-in-symfony-3-2-user-value-resolver-for-controllers
这很简单:
use Symfony\Component\Security\Core\User\UserInterface
public function indexAction(UserInterface $user)
{...}

在symfo 4中:
use Symfony\Component\Security\Core\Security;
class ExampleService
{
private $security;
public function __construct(Security $security)
{
$this->security = $security;
}
public function someMethod()
{
$user = $this->security->getUser();
}
}
参阅文档:https://symfony.com/doc/current/security.html#retrieving-the-user-object
答案 5 :(得分:2)
Symfony在Symfony \ Bundle \ FrameworkBundle \ ControllerControllerTrait中执行此操作
protected function getUser()
{
if (!$this->container->has('security.token_storage')) {
throw new \LogicException('The SecurityBundle is not registered in your application.');
}
if (null === $token = $this->container->get('security.token_storage')->getToken()) {
return;
}
if (!is_object($user = $token->getUser())) {
// e.g. anonymous authentication
return;
}
return $user;
}
因此,如果您只是注入并替换security.token_storage
,那么您就可以了。

如果你扩展Controller
$this->get('security.context')->getToken()->getUser();
或者,如果您有权访问容器元素..
$container = $this->configurationPool->getContainer();
$user = $container->get('security.context')->getToken()->getUser();

这在 Symfony 5.2 中运行良好
$this->get('security.token_storage')->getToken()->getUser()
