Question

我在我的应用程序中使用第三方软件包进行通知。它一切正常，但我想覆盖服务的某些部分＆＃34; NotificationManager＆＃34;该捆绑包，以便将通知与电子邮件相结合。

错误实现一切后，我收到以下错误消息：

Type error: Argument 1 passed to Mgilet\NotificationBundle\Twig\NotificationExtension::__construct() must be an instance of Mgilet\NotificationBundle\Manager\NotificationManager, instance of NewsBundle\Services\NotificationHelper given, called in /srv/http/sp/app/cache/dev/appDevDebugProjectContainer.php on line 4011

我做了什么 我按照Symfony文档并添加了CompilerPass：

    <?php
namespace NewsBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use NewsBundle\Services\NotificationHelper;

class OverrideCompilerPass implements CompilerPassInterface {

  public function process(ContainerBuilder $container)
      {
          $defNewService = $container->getDefinition('mgilet.notification');
          $defNewService->setClass('NewsBundle\Services\NotificationHelper');

      }

}
  ?>

并将我的自定义包标记为NotificationBundle的继承：

    <?php

namespace NewsBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;
use Mgilet\NotificationBundle\MgiletNotificationBundle;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use NewsBundle\DependencyInjection\OverrideCompilerPass;

class NewsBundle extends MgiletNotificationBundle
{
  public function build(ContainerBuilder $container)
   {
       parent::build($container);
       $container->addCompilerPass(new OverrideCompilerPass());
   }
}

然后，我基本上复制并粘贴了第三方软件包中的服务类，只是为了仔细检查一切是否仍然正常。

 <?php
namespace NewsBundle\Services;

use Doctrine\ORM\EntityManager;
use Mgilet\NotificationBundle\Model\AbstractNotification;
use Mgilet\NotificationBundle\Model\UserNotificationInterface;

class NotificationHelper{
      private $om;
      private $notification;
      private $repository;

      /**
       * NotificationHelper constructor.
       * @param EntityManager $om
       * @param $notification
       * @internal param $class
       */
      public function __construct(EntityManager $om, $notification)
      {
          $this->om = $om;
          $this->notification = $notification;
          $this->repository = $om->getRepository($notification);
      }
... all the functions from the bundle

}

现在我还需要一个Twig扩展来使一切正常工作，我的错误出现在这里：

<?php

namespace NewsBundle\Twig;

use Mgilet\NotificationBundle\Twig\NotificationExtension as BaseExtension;
use NewsBundle\Services\NotificationHelper;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage;
use Twig_Extension;

class NotificationExtension extends BaseExtension
/**
 * Twig extension to display notifications
 **/
{
    protected $notificationHelper;
    protected $storage;
    protected $twig;

    /**
     * NotificationExtension constructor.
     * @param NotificationHelper $notificationHelper
     * @param TokenStorage $storage
     * @param \Twig_Environment $twig
     */
    public function __construct(NotificationHelper $notificationHelper, TokenStorage $storage, \Twig_Environment $twig)
    {
        $this->notificationHelper = $notificationHelper;
        $this->storage = $storage;
        $this->twig = $twig;
    }
... stuff happening
}

我认为通过替换构造函数的第一个参数，use语句会自动覆盖第三方包，但似乎它并没有真正起作用。

在我的config.yml文件中，我有：

     notification_helper:
      class: NewsBundle\Services\NotificationHelper
      arguments: ['@doctrine.orm.entity_manager', AppBundle\Entity\Notification]

  notification.twig_extension:
          class: NewsBundle\Twig\NotificationExtension
          arguments: ['@notification_helper', '@security.token_storage', '@twig']
          public: false
          tags:
              - { name: twig.extension }

更新

我编辑了services.yml，所以现在只剩下twig_extension作为服务，因为当我调试mgilet.notification-service时，它已经被分配给我的自定义Service类了，所以我认为它只是相同..

所以现在我只在我的文件中有这个：

    notification.twig_extension:
      class: NewsBundle\Twig\NotificationExtension
      arguments: ['@mgilet.notification', '@security.token_storage', '@twig']
      public: false
      tags:
          - { name: twig.extension }

调试容器时，它甚至不显示为服务，但错误信息保持不变：

Type error: Argument 1 passed to Mgilet\NotificationBundle\Twig\NotificationExtension::__construct() must be an instance of Mgilet\NotificationBundle\Manager\NotificationManager, instance of NewsBundle\Services\NotificationHelper given, called in /srv/http/sp/app/cache/dev/appDevDebugProjectContainer.php on line 4000

Answer 1

我认为NotificationExtension需要NotificationManager类。您应该从services.yml发送此类。但是你要发送你的服务类; NotificationHelper。您应该发送添加一个，它是Notification Manager类。所以NotificationHelper在NotificationBundle中。
