“无法将服务“Album\Controller\AlbumController”解析到工厂；您确定是在配置期间提供的吗？在 Zend 框架 2 中

Question

我在 Zend Framework 2 教程项目中遇到错误，因为，

Unable to resolve service "Album\Controller\AlbumController" to a factory; are you certain you provided it during configuration?

我的 Module.php 作为

namespace Album;

use Zend\ModuleManager\Feature\ConfigProviderInterface;

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

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)
                );
            },
        ],
    ];
}
}

而我的 module.config.php 是；

namespace Album;

use Zend\Router\Http\Segment;

//use Zend\ServiceManager\Factory\InvokableFactory;

return [
'controllers' => [
    'factories' => [
        Controller\AlbumController::class => InvokableFactory::class,
    ],
],

'router' => [
    'routes' => [
        'album' => [
            'type'    => Segment::class,
            'options' => [
                'route' => '/album[/:action[/:id]]',
                'constraints' => [
                    'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                    'id'     => '[0-9]+',
                ],
                'defaults' => [
                    'controller' => Controller\AlbumController::class,
                    'action'     => 'index',
                ],
            ],
        ],
    ],
],

'view_manager' => [
    'template_path_stack' => [
        'album' => __DIR__ . '/../view',
    ],
],
];

我对 Zend 框架很陌生。只是无法弄清楚我做错了什么。请提及是否需要更多代码。

Answer 1

您已经为“Controller\AlbumController::class”定义了两个工厂...

一个在 module.config.php -

return [
    'controllers' => [
        'factories' => [
             Controller\AlbumController::class => InvokableFactory::class,
        ],
     ],
],

和第二个在 Module.php-

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

它们彼此冲突。可调用工厂用于没有任何依赖关系的类。在这种情况下，它看起来像“AlbumController”依赖于“AlbumTable”，所以第二个选项看起来像你想要的。

简而言之，从module.config.php 中的数组中删除'controllers' 键值。

希望这可以帮助！
