错误来自AlbumController构造函数,它需要在创建前者时注入AlbumTable对象。
控制器在
创建Controller\AlbumController::class => InvokableFactory::class,
使用没有构造函数参数的标准工厂。
您需要将其更改为:
Controller\AlbumController::class => function($container) {
return new Controller\AlbumController(
$container->get(\Album\Model\AlbumTable::class)
);
},
以便为工厂提供依赖性(AlbumTable)。
AlbumTable也应该有自己的工厂(也许你的配置中已经有了这个):
use Zend\Db\ResultSet\ResultSet;
use Zend\Db\TableGateway\TableGateway;
'service_manager' => [
'factories' => [
\Album\Model\AlbumTable::class => function($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&#39;专辑&#39; at TableGateway('album')
是您的数据库表名。

Controller\AlbumController::class => InvokableFactory::class,
更改为
Controller\AlbumController::class => Controller\AlbumControllerFactory::class,
然后在Controller dir中创建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AlbumModel的工厂,你可以用同样的方式创建它 所以你的modlue.config.php看起来就像是。
....
'controllers' => [
'factories' => [
Controller\AlbumController::class => Controller\AlbumControllerFactory::class,
],
],
'service_manager' => [
'factories' => [
Model\AlbumModel::class => Model\AlbumModelFactory::class,
],
],
....
