Question

我是ZF3的新手，我需要你的帮助。在ZF3中，没有服务定位器了。所以我创建了一个Factory类来替换我的代码中的服务定位器。

以下是我在AbstractController.php文件中使用服务定位器的代码：

protected function getService()
{
    return $this->getServiceLocator()->get($service); //remove from ZF3
    return $this->service = $service;
}

现在我替换了AbstractController.php中的服务定位器：

protected function getService($service)
{
    $service = $this->service;
    return $this->service = $service;
}

在Module.Config.php中，我添加了以下几行：

return [
    'controllers' => [
        'factories' => [
            Controller\AbstactController::class => Controller\AbstactControllerFactory::class,
        ],
],

我创建了一个AbstractControllerFactory文件，其中包含以下行：

<?php

namespace Application\Controller;

use Application\Controller\AbstractController;
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;

    class AbstractControllerFactory implements FactoryInterface
    {
        protected function __invoke(ContainerInterface $container, $requestedName, array $options = null)
        {
            return new AbstractController($container->get(service::class));
        }
    }

我需要知道这是否是从ZF2到ZF3的正确迁移？

在ZF3中，您要做的第一件事就是为它创建服务和工厂。让我们在服务文件夹中接受这个示例UserManager.php。

所以我们在文件夹服务 - ＆gt; UserManager.php 以及服务 - ＆gt; 工厂 - ＆gt;的 UserManagerFactory.php

<强> UserManagerFactory.php：

<?php namespace User\Service\Factory; use Interop\Container\ContainerInterface; use User\Service\UserManager; /** * This is the factory class for UserManager service. The purpose of the factory * is to instantiate the service and pass it dependencies (inject dependencies). */ class UserManagerFactory { /** * This method creates the UserManager service and returns its instance. */ public function __invoke(ContainerInterface $container, $requestedName, array $options = null) { $entityManager = $container->get('doctrine.entitymanager.orm_default'); return new UserManager($entityManager); } }

<强> UserManager.php：

<?php namespace User\Service; use User\Entity\User; /** * This service is responsible for adding/editing users * and changing user password. */ class UserManager { /** * Doctrine entity manager. * @var Doctrine\ORM\EntityManager */ private $entityManager; /** * Constructs the service. */ public function __construct($entityManager) { $this->entityManager = $entityManager; } // REST OF YOUR CODE }

现在我们有了服务，我们进入 User \ config \ modules.config.php ：

'service_manager' => [ 'factories' => [ Service\UserManager::class => Service\Factory\UserManagerFactory::class, ], ],

基本上就是这样，我们可以在我们的控制器中注入服务并完成工作：

<?php namespace User\Controller; use Zend\Mvc\Controller\AbstractActionController; /** * This controller is responsible for user management (adding, editing, * viewing users and changing user's password). */ class UserController extends AbstractActionController { /** * User manager. * @var User\Service\UserManager */ private $userManager; /** * Constructor. */ public function __construct($userManager) { $this->userManager = $userManager; } // REST OF YOUR CODE }

我真的希望这有助于您了解如何在ZF3中使用Service。

祝你好运！

没有getServicelocator（）从ZF2迁移到ZF 3;
