PHP-DI没有与ZendFramework2集成。

Question

请给出一个提示，为什么PHP与Zend 2的集成不适合我(转载于Apache/2.4.9 (Win64) PHP/5.5.12和Apache2.2.22 (Win32) PHP/5.3.13)。

composer.json

{
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "2.3.5",
        "mnapoli/php-di": "4.4.6",
        "mnapoli/php-di-zf2": "0.3.0",
       ...
},
    ...

config\application.config.php

<?php
return array(
    'modules' => array(
        'Morpho',
        'DI\ZendFramework2',
    ),
    'module_listener_options' => array(
        'module_paths' => array(
            './module',
            './vendor',
        ),
    ),
);
?>

module/Morpho/config.module.config.php

<?php
return array(
    'service_manager' => array(
        'factories' => array(
            'DI\Container' => function() {
                $builder = new DI\ContainerBuilder();
                $builder->addDefinitionsFromFile("config/di.yml");
                return $builder->build();
            },
        ),
    ),
    'router' => array(
        ...
    ),
    'controllers' => array(
        ...
    ),
    'view_manager' => array(
        ...
    ),
);

config/di.yml

Morpho\Service\PartOfSpeechService:
    class: Morpho\Service\PhpMorphyPartOfSpeechService

module/Morpho/src/Morpho/Controller/PartOfSpeechController

class PartOfSpeechController extends AbstractRestfulController {
    ...
    /**
     * @Inject
     * @var PartOfSpeechService
     */
    public $partOfSpeechService;

    public function processPostData(Request $request) {
        $partsOfSpeech = $this->partOfSpeechService->getPartsOfSpeech("test", "en_EN");
        return new JsonModel($partsOfSpeech);
    }
}

每次在apache下运行此代码时：

PHP Fatal error:  Uncaught exception 'Zend\ModuleManager\Exception\RuntimeException'
with message 'Module (DI\ZendFramework2) could not be initialized.' in \vendor\zendframework\zendframework\library\Zend\ModuleManager\ModuleManager.php:195

4 \vendor\zendframework\zendframework\library\Zend\EventManager\EventManager.php(207): Zend\EventM in \vendor\zendframework\zendframework\library\Zend\ModuleManager\ModuleManager.php on line 195

任何你的想法都会很感激的。

服务的：

工厂配置：

        'factories' => array(
            'MyService' => 'Application\Factory\MyService',
        ),

工厂级：

class MyService implements FactoryInterface
{

    public function createService(ServiceLocatorInterface $serviceManager)
    {
        $purifier = new MyService($serviceManager->get('MyAwesomeDependency'));
        return $purifier;
    }
}

控制器的：

ControllerFactory.php：

class PartOfSpeechControllerFactory
{
    public function __invoke($serviceLocator)
    {
        // Service locator here is the ControllerManager so get ServiceManager 
        $serviceManager = $serviceLocator->getServiceLocator();

        $controller = new PartOfSpeechController($serviceManager->get('PartOfSpeechService'));

        return $controller;
    }
}

类PartOfSpeechController.php

class PartOfSpeechController extends AbstractRestfulController {


    protected $partOfSpeechService;

    public function __construct(PartOfSpeechService $partOfSpeechService)
    {
         $this->partOfSpeechService = $partOfSpeechService;
    }


    public function processPostData(Request $request) {
         $var = $this->partOfSpeechService->serviceMethod();   
    }
}

控制器的配置：

'factories' => array(
                'Application\Controller\PartOfSpeechController' => 'Application\Factory\PartOfSpeechControllerFactory'
        ),

Answer 2

它不能工作，因为您使用的是旧的YAML语法，而是因为PHP v4.0语法现在是PHP。

转到文档中学习语法：http://php-di.org/doc/definition.html

我遵循了紫色六角的建议，下面是一个使用服务管理器的工作实现：

module/Morpho/config

...
'service_manager' => array(
    'services' => array(
        "PartOfSpeechService" => new Morpho\Service\PhpMorphyPartOfSpeechService(),
    ),
),
...

module/Morpho/src/Morpho/Controller/PartOfSpeechController.php

class PartOfSpeechController extends AbstractRestfulController {
    ...
    public function processPostData(Request $request) {
        $serviceManager = $this->getServiceLocator();
        $partsOfSpeech = $serviceManager->get("PartOfSpeechService")->getPartsOfSpeech($request->getPost("phrase"),
                $request->getPost("language"));
        return new JsonModel($partsOfSpeech);
    }
}

为什么我不喜欢这样：

1. 我必须使用“虚拟”代码来获得serviceManager。这是“虚拟的”，因为这与我的应用程序的业务逻辑完全无关。
2. ServiceManager提供的依赖注入方法使我的代码依赖于ServiceManager本身。通常，我不应该关心bean/对象是如何注入的，因此不应该在代码中引用任何类型的容器或ServiceManager。

我认为PHP-DI更接近Java使用的bean注入模型(我认为它很好)。不幸的是，它仍然对我不起作用。最后，从容器中获取对象的方法也在PHP中工作.
