Zend Framework 2：传递给Album \ Controller \ AlbumController :: __ construct（）的参数1必须是Album \ Controller \ AlbumTable的一个实例

Question

我得到一个错误;

Argument 1 passed to Album\Controller\AlbumController::__construct() must be an instance of Album\Controller\AlbumTable, instance of Album\Model\AlbumTable given,, called in /var/www/html/zf/module/Album/src/Module.php on line 43 

My Module.php is;

<?php 
    namespace Album; 

    use Zend\ModuleManager\Feature\ConfigProviderInterface; 
    use Zend\Db\Adapter\AdapterInterface; 
    use Zend\Db\ResultSet\ResultSet; 
    use Zend\Mvc\ModuleRouteListener; 
    use Zend\Mvc\MvcEvent; 
    use Zend\Db\TableGateway\TableGateway; 

class Module implements ConfigProviderInterface 
{ 
public function getConfig() 
{ 
    return include __DIR__ . '/../config/module.config.php'; 
} 

// Add this method: 
public function getServiceConfig() 
{ 
    return [ 
     'factories' => [ 
      Model\AlbumTable::class => function($container) { 
       $tableGateway = $container->get(Model\AlbumTableGateway::class); 
       return new Model\AlbumTable($tableGateway); 
      }, 
      Model\AlbumTableGateway::class => function ($container) { 
       $dbAdapter = $container->get(AdapterInterface::class); 
       $resultSetPrototype = new ResultSet(); 
       $resultSetPrototype->setArrayObjectPrototype(new Model\Album()); 
       return new TableGateway('album', $dbAdapter, null, $resultSetPrototype); 
      }, 
     ], 
    ]; 
} 

public function getControllerConfig() 
{ 
    return [ 
      'factories' => [ 
      Controller\AlbumController::class => function($container) { 
       return new Controller\AlbumController(
        $container->get(Model\AlbumTable::class) 
       ); 
      }, 
      ], 
     ]; 
    } 
} 

我的AlbumController就像;

<?php 
namespace Album\Controller; 

use Zend\Mvc\Controller\AbstractActionController; 
use Zend\View\Model\ViewModel; 

use Album\Model; 

class AlbumController extends AbstractActionController 
{ 
// Add this property: 
private $table; 

// Add this constructor: 
public function __construct(AlbumTable $table) 
{ 
    $this->table = $table; 
} 

public function indexAction() 
{ 
    return new ViewModel([ 
     'albums' => $this->table->fetchAll(), 
    ]); 
} 

public function addAction() 
{ 
} 

public function editAction() 
{ 
} 

public function deleteAction() 
{ 
} 
} 

能否请你告诉我什么，我做错了什么？我在Zend Framework中很新。这是我试图运行的教程应用程序。我遵循所有步骤，但有很多问题，我一一解决了所有这些问题，现在我被困在这里。

Answer 1

你正在使用非法的依赖可以这么说，

// Here you are returning Model\AlbumTable object 
// while your Controller\AlbumController needs a Controller\AlbumTable instance 
return new Controller\AlbumController(
    $container->get(Model\AlbumTable::class) 
); 

所以要解决这个问题：

return new Controller\AlbumController(
    $container->get(Controller\AlbumTable::class) 
);

的情况下，如果你需要使用型号\ AlbumTable作为依赖，所以您需要将其设置在控制器中，如下所示：

use Model\AlbumTable as AlbumTableModel; 

... 
... 

public function __construct(AlbumTableModel $table) 
{ 
    $this->table = $table; 
}
