ZF2模块配置service_manager添加构造函数参数

Question

我一直在寻找并尝试了一段时间，我无法找出我在做什么错... 我一直在阅读一些文档，并尝试过许多不同的方法。

我希望你们中的一个可以帮助我..

我的想法： 我有一个名为应用模块。在这个模块中有一个\Application\Controller\IndexController这是用来显示我的应用程序的主页。 IndexController需要一个\Zend\http\Client的对象，所以我应该使用\Application\Module->getServiceConfig()返回的配置中的工厂密钥，并添加一个构造函数，其中包含所需的参数\Zend\Http\Client $client。

不幸的是这是行不通的..

我的代码：

<?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：

Catchable fatal error: Argument 1 passed to Application\Controller\IndexController::__construct() must be an instance of Zend\Http\Client, none given, called in /var/www/library/Zend/ServiceManager/AbstractPluginManager.php on line 170 and defined in /var/www/module/Application/src/Application/Controller/IndexController.php on line 13

您需要实现在Module.php的getControllerConfig方法做你'再问，控制器有自己的管理器，请从getServiceConfig中删除你所拥有的，并使用下面的代替

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

您还需要删除控制器invokables线在module.config.php，因为它会与你的工厂发生冲突

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