PHP-DI无法与ZendFramework2集成工作

Question

你能告诉我为什么PHP-DI与Zend Framework 2的集成不适合我吗（用Apache/2.4.9（Win64）PHP/5.5.12和Apache/2.2.22（Win32）PHP/55.3.13复制）。

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',
        'DIZendFramework2',
    ),
    'module_listener_options' => array(
        'module_paths' => array(
            './module',
            './vendor',
        ),
    ),
);
?>

module/Morpho/config.module.config.php:

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

config/di.yml：

MorphoServicePartOfSpeechService:
    class: MorphoServicePhpMorphyPartOfSpeechService

模块/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，我都会得到：

PHP Fatal error:  Uncaught exception 'ZendModuleManagerExceptionRuntimeException'
with message 'Module (DIZendFramework2) could not be initialized.' in vendorzendframeworkzendframeworklibraryZendModuleManagerModuleManager.php:195
Stack trace:

4 vendorzendframeworkzendframeworklibraryZendEventManagerEventManager.php(207): ZendEventM in vendorzendframeworkzendframeworklibraryZendModuleManagerModuleManager.php on line 195

如果您有任何想法，我们将不胜感激。

Answer 1

它不起作用，因为您使用的是旧的YAML语法，但由于PHP-DI v4.0，现在的语法是PHP。

前往文档了解语法：http://php-di.org/doc/definition.html

Answer 2

对于服务：

出厂配置：

        'factories' => array(
            'MyService' => 'ApplicationFactoryMyService',
        ),

工厂等级：

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

对于控制器：

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;
    }
}

class 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(
                'ApplicationControllerPartOfSpeechController' => 'ApplicationFactoryPartOfSpeechControllerFactory'
        ),

我遵循了Purple Hexagon给出的建议，下面是一个使用Service Manager:的工作实现

模块/Morpho/config：

...
'service_manager' => array(
    'services' => array(
        "PartOfSpeechService" => new MorphoServicePhpMorphyPartOfSpeechService(),
    ),
),
...

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);
    }
}

为什么我不喜欢这个：

1. 我必须使用一个"伪"代码来获得serviceManager。这是"伪"，因为这与我的应用程序的业务逻辑根本无关
2. ServiceManager提供的依赖注入方法使我的代码依赖于ServiceManager本身。通常，我不应该关心如何注入bean/对象，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JavaSpring使用的bean注入模型（我认为这很好）。不幸的是，它仍然不适用于我。最后，从容器中获取对象的方法也在PHP-DI中工作。
