可捕捉的致命错误：传递给Album \ Controller \ AlbumController :: __ construct（）的参数1必须是Album \ Model \ AlbumTable的一个实例，没有给出

Question

我刚刚通过文档安装了该项目;和我收到此错误：

错误

Answer 1

的错误来自AlbumController构造，其预期在创建前当待注入的AlbumTable对象。

该控制器在

Controller\AlbumController::class => InvokableFactory::class, 

使用标准工厂没有构造参数创建。

您需要此更改为：使本厂提供的扶养（AlbumTable）

Controller\AlbumController::class => function($container) { 
    return new Controller\AlbumController(
     $container->get(\Album\Model\AlbumTable::class) 
    ); 
}, 

。

而且AlbumTable应该有自己的工厂（也许你已经有这个在你的配置）。

use Zend\Db\ResultSet\ResultSet; 
use Zend\Db\TableGateway\TableGateway; 

'service_manager' => [ 
     'factories' => [ 
      \Album\Model\AlbumTable::class => function($sm) { 
       $tableGateway = $sm->get('AlbumTableGateway'); 
       $table = new \Album\Model\AlbumTable($tableGateway); 
       return $table; 
      }, 
      'AlbumTableGateway' => function ($sm) { 
       $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter'); 
       $resultSetPrototype = new ResultSet(); 
       return new TableGateway('album', $dbAdapter, null, $resultSetPrototype); 
      }, 
     ] 
    ], 

其中TableGateway“专辑”（“专辑”是你的数据库表名

Answer 2

Controller\AlbumController::class => InvokableFactory::class, 

变化

Controller\AlbumController::class => Controller\AlbumControllerFactory::class, 

然后在控制器DIR生成AlbumControllerFactory类

namespace Album\Controller; 

use Album\Controller\AlbumController; 
use Zend\ServiceManager\Factory\FactoryInterface; 
use Interop\Container\ContainerInterface; 
use Album\Model\AlbumTable; 

class AlbumControllerFactory implements FactoryInterface { 
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null){ 
     $model = $container->get(AlbumTable::class); 
     return new AlbumController($model); 
    } 
} 

另外，如果你没有工厂AlbumModel可以创建一个同样的方式 所以你modlue.config.php看起来像如。

.... 
'controllers' => [ 
    'factories' => [ 
     Controller\AlbumController::class => Controller\AlbumControllerFactory::class, 
    ], 
], 
'service_manager' => [ 
    'factories' => [ 
     Model\AlbumModel::class => Model\AlbumModelFactory::class, 
    ], 
], 
....
