ZF2模块配置service_manager添加构造函数参数


ZF2 module config service_manager add constructor param

我已经搜索和尝试了一段时间了,我找不到我做错了什么…我现在已经阅读了相当多的文档,并尝试了很多不同的方法。

我希望你们中有人能帮我一把。

我的想法:我有一个叫做Application的模块。在这个模块中有一个'Application'Controller'IndexController,用来显示我的应用程序的主页。IndexController需要一个具有'Zend'http'Client的对象,所以我认为我应该在由'Application'Module->getServiceConfig()返回的配置中使用工厂键,并添加一个具有所需参数'Zend'Http'Client $client的构造函数。

不幸的是这不起作用。

我代码:

<?php
// module/Application/Module.php
namespace Application;
use Zend'Mvc'ModuleRouteListener;
use Zend'Mvc'MvcEvent;
class Module
{
    public function getConfig()
    {
        return include __DIR__ . '/config/module.config.php';
    }
    public function getServiceConfig()
    {
        return array(
            'factories' => array(
                'IndexController' => function($serviceManager) {
                    $httpClient = 'Zend'Http'Client;
                    return new IndexController($httpClient);
                },
            ),
        );
    }
    public function getAutoloaderConfig()
    {
        return array(
            'Zend'Loader'StandardAutoloader' => array(
                'namespaces' => array(
                    __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
                ),
            ),
        );
    }
}
<?php
// module/Application/config/module.config.php
return array(
    'router' => array(
        'routes' => array(
            'home' => array(
                'type' => 'Zend'Mvc'Router'Http'Literal',
                'options' => array(
                    'route' => '/',
                    'defaults' => array(
                        'controller' => 'Application'Controller'Index',
                        'action' => 'index',
                    ),
                ),
            )
        ),
    ),
    'service_manager' => array(
        'factories' => array(
            'translator' => 'Zend'I18n'Translator'TranslatorServiceFactory',
        ),
    ),
    'translator' => array(
        'locale' => 'en_US',
        'translation_file_patterns' => array(
            array(
                'type' => 'gettext',
                'base_dir' => __DIR__ . '/../language',
                'pattern' => '%s.mo',
            ),
        ),
    ),
    'controllers' => array(
        'invokables' => array(
            'Application'Controller'Index' => 'Application'Controller'IndexController'
        ),
    ),
    'view_manager' => array(
        'display_not_found_reason' => true,
        'display_exceptions' => true,
        'doctype' => 'HTML5',
        'not_found_template' => 'error/404',
        'exception_template' => 'error/index',
        'template_map' => array(
            'layout/layout' => __DIR__ . '/../view/layout/layout.phtml',
            'application/index/index' => __DIR__ . '/../view/index/index.phtml',
            'error/404' => __DIR__ . '/../view/error/404.phtml',
            'error/index' => __DIR__ . '/../view/error/index.phtml',
        ),
        'template_path_stack' => array(
            __DIR__ . '/../view',
        ),
    ),
);
<?php
// module/Application/src/Application/Controller/IndexController.php
namespace Application'Controller;
use Zend'Mvc'Controller'AbstractActionController;
use Zend'View'Model'ViewModel;
class IndexController extends AbstractActionController
{
    protected $httpClient;
    public function __construct('Zend'Http'Client $client)
    {
        $this->httpClient = $client;
    }
    public function getHttpClient()
    {
        return $this->httpClient;
    }
    public function indexAction()
    {                
        $httpClient = $this->getHttpClient();
        return new ViewModel();
    }
}

错误:

可捕获的致命错误:参数1传递给Application'Controller'IndexController::__construct()必须是Zend'Http'Client的一个实例,没有给出,在/var/www/library/Zend/servicemanager/AbstractPluginManager.php第170行调用,并在/var/www/module/Application/src/Application/Controller/IndexController.php第13行定义

你需要在Module.php中实现getControllerConfig方法来做你想做的事情,控制器有自己的管理器,从getServiceConfig中删除你所拥有的,并使用下面的

public function getControllerConfig()
{
    return array(
        'factories' => array(
            'Application'Controller'Index' => function($serviceManager) {
                $httpClient = new 'Zend'Http'Client;
                return new 'Application'Controller'IndexController($httpClient);
            },
        ),
    );
}

你还需要从module.config.php中的控制器可调用中删除这一行,因为它会与你的工厂

冲突。
'controllers' => array(
    'invokables' => array(
        // this line's no longer needed
        //'Application'Controller'Index'      => 'Application'Controller'IndexController',
    ),
),
