Question

我正在尝试将当前登录的用户注入服务。我的目标是扩展一些树枝功能，根据用户偏好输出它。在这个例子中，我想使用用户特定的时区输出任何日期函数。

似乎没有办法将当前用户注入服务，这对我来说似乎很奇怪。注入安全上下文时，即使用户已登录，它也没有令牌

我正在使用FOS用户包。

services:
    ...
    twigdate.listener.request:
        class: App\AppBundle\Services\TwigDateRequestListener
        arguments: [@twig, @security.context]
        tags:
            - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }


<?php

namespace App\AppBundle\Services;

use Symfony\Component\HttpKernel\HttpKernelInterface;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;

class TwigDateRequestListener
{
    protected $twig;

    function __construct(\Twig_Environment $twig, SecurityContext $context) {

        $this->twig = $twig;
        //$this->user = $context->get...;

        var_dump($context); die;
    }

    public function onKernelRequest(GetResponseEvent $event) {
       // $this->twig->getExtension('core')->setDateFormat($user->getProfile()->getFormat());
       // $this->twig->getExtension('core')->setTimeZone($user->getProfile()->getTimezone());
    }
}

output:

object(Symfony\Component\Security\Core\SecurityContext)[325]
  private 'token' => null
  private 'accessDecisionManager' => 
    object(Symfony\Component\Security\Core\Authorization\AccessDecisionManager)[150]
      private 'voters' => 
        array
          0 => 
            object(Symfony\Component\Security\Core\Authorization\Voter\RoleHierarchyVoter)[151]
              ...
          1 => 
            object(Symfony\Component\Security\Core\Authorization\Voter\AuthenticatedVoter)[153]
              ...
          2 => 
            object(Symfony\Component\Security\Acl\Voter\AclVoter)[155]
              ...
      private 'strategy' => string 'decideAffirmative' (length=17)
      private 'allowIfAllAbstainDecisions' => boolean false
      private 'allowIfEqualGrantedDeniedDecisions' => boolean true
  private 'authenticationManager' => 
    object(Symfony\Component\Security\Core\Authentication\AuthenticationProviderManager)[324]
      private 'providers' => 
        array
          0 => 
            object(Symfony\Component\Security\Core\Authentication\Provider\DaoAuthenticationProvider)[323]
              ...
          1 => 
            object(Symfony\Component\Security\Core\Authentication\Provider\AnonymousAuthenticationProvider)[149]
              ...
      private 'eraseCredentials' => boolean true
  private 'alwaysAuthenticate' => boolean false

我错过了什么吗？

Answer 1

我认为自从新安全组件改进以来2.6.x +以来，这个问题值得更新。

use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage;

class UserDateExtension extends \Twig_Extension
{
    /**
     * @var TokenStorage
     */
    protected $tokenStorage;


    /**
     * @param \Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage    $tokenStorage
     */
    public function __construct(TokenStorage $tokenStorage)
    {
        $this->tokenStorage = $tokenStorage;
    }

    public function getUser()
    {
        return $this->tokenStorage->getToken()->getUser();
    }

    public function getFilters()
    {
        return array(
            'user_date' => new \Twig_Filter_Method($this, "formatUserDate"),
        );
    }

    public function formatUserDate($date, $format)
    {
        $user = $this->getUser();
        // do stuff
    }
}

Services.yml

twig.date_extension:
    class: Acme\Twig\SpecialDateExtension
    tags:
        - { name: twig.extension }
    arguments:
        - "@security.token_storage"

Answer 2

我会使用枝条延伸：

class UserDateExtension extends \Twig_Extension
{
    private $context;

    public function __construct(SecurityContext $context)
    {
        $this->context = $context;
    }

    public function getUser()
    {
        return $this->context->getToken()->getUser();
    }

    public function getFilters()
    {
        return array(
            'user_date' => new \Twig_Filter_Method($this, "formatUserDate"),
        );
    }

    public function formatUserDate($date, $format)
    {
        $user = $this->getUser();
        // do stuff
    }

现在在services.xml

    <service id="user_date_twig_extension" class="%user_date_twig_extension.class%">
        <tag name="twig.extension" />
        <argument type="service" id="security.context" />
    </service>

然后在树枝上你可以做到：

{{ date | user_date('d/m/Y') }}

Answer 3

services.yml

my_service:
    class: ...
    arguments:
        - "@=service('security.token_storage').getToken().getUser()"

Service.php

protected $currentUser;

public function __construct($user)
{
    $this->currentUser = $user;
}

Answer 4

用户是服务的不良候选人。

首先是模型而不是服务
其次是服务 security.context ，您可以从中获取用户。

在twig模板中，您可以使用 app.user 。请参阅symfony doc global-template-variables。如果您想根据用户权限显示某些内容，可以执行{{is_granted（'ROLE_USER'）}}。

Answer 5

来自Symfony 2.6。

您需要使用@ security.token_storage

use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class UserDateExtension extends \Twig_Extension
{
/**
 * @var TokenStorageInterface
 */
protected $tokenStorage;


/**
 * @param $tokenStorage TokenStorage
 */
public function __construct(TokenStorage $tokenStorage)
{
    $this->tokenStorage = $tokenStorage;
}

public function getUser()
{
    return $this->tokenStorage->getToken()->getUser();
}

public function getFilters()
{
    return array(
        'user_date' => new \Twig_Filter_Method($this, "formatUserDate"),
    );
}

public function formatUserDate($date, $format)
{
    $user = $this->getUser();
    // do stuff
}

}

和Services.yml

twig.date_extension:
    class: Acme\Twig\SpecialDateExtension
    tags:
        - { name: twig.extension }
    arguments: ["@security.token_storage"]

Answer 6

我建议绑定一个不同的事件，如果你使用kernel.controller事件，你将有一个令牌，没有问题。自kernel.request

以来Symfony 2.3中无法使用该令牌

我在我的博客Symfony 2.6+ User Timezones上写了一篇关于如何在Twig中为Symfony 2.3+和2.6+实现用户时区的指南。

这远远优于使用Twig扩展，因为您可以使用Twig中的标准日期格式化功能，以及提供单独的后端UTC日期，默认的Twig日期时区和用户定义的Twig日期时区。

以下是最重要的摘录：

的src /的appbundle /事件监听/ TwigSubscriber.php

<?php

namespace AppBundle\EventListener;

use AppBundle\Entity\User;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\FilterControllerEvent;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class TwigSubscriber implements EventSubscriberInterface
{
    protected $twig;
    protected $tokenStorage;

    function __construct(\Twig_Environment $twig, TokenStorageInterface $tokenStorage)
    {
        $this->twig = $twig;
        $this->tokenStorage = $tokenStorage;
    }

    public static function getSubscribedEvents()
    {
        return [
            'kernel.controller' => 'onKernelController'
        ];
    }

    public function onKernelController(FilterControllerEvent $event)
    {
        $token = $this->tokenStorage->getToken();

        if ($token !== null) {
            $user = $token->getUser();

            if ($user instanceof User) {
                $timezone = $user->getTimezone();
                if ($timezone !== null) {
                    $this->twig->getExtension('core')->setTimezone($timezone);
                }
            }
        }
    }
}

现在您可以正常使用树枝，如果可用，它会使用您的用户偏好设置。

Answer 7

您可以尝试注入@service_container并执行$this->container->get('security.context')->getToken()->getUser();。

Symfony2：在服务中注入当前用户
