Question

我试图看到做一个twig扩展，但我挂在@ security.context注入，因为它给我一个错误，我在构造函数中添加参数？我有几个人在互联网上搜索，但问题是我找不到解决方案是我做错了什么？

目标是注入security.context以访问当前用户。

<?php
namespace Acme\AppBundle\Twig\Extension;

use Symfony\Component\Security\Core\SecurityContextInterface;

class reserveExtension extends \Twig_Extension
{
    protected $context;

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

    public function getFilters()
    {
        return array(new \Twig_SimpleFilter('reserve_currentUser', array($this, 'reserveCurrentUser')));
    }

    function reserveCurrentUser($entity)
    {
        var_dump($this->context->getToken()->getUser());
    }

    public function getName()
    {
        return 'twig_extension_reserve';
    }
}

服务定义：

services:
reserveExtension:
    class: Acme\AppBundle\Twig\Extension\reserveExtension
    arguments: [@security.context]
    tags:
        - { name: twig.extension }

错误：

Catchable Fatal Error: Argument 1 passed to Acme\AppBundle\Twig\Extension\ReserveExtension::__construct() must be an instance of Acme\AppBundle\Twig\Extension\SecurityContext, instance of Symfony\Component\Security\Core\SecurityContext given, called in D:\wamp\www\Acme\app\cache\dev\appDevDebugProjectContainer.php on line 432 and defined

谢谢！

您的使用声明有误，您有use ...\SecurityContextInterface，但实际代码中有SecurityContext，请更改其中一个。

带参数的twig扩展
