Php Zend\ServiceManager\ServiceManager::get无法获取或创建getAlbumTable的实例
我正在尝试修改和复制一个自定义模块,我已经设置了DB connection的所有内容,但在查看我的模块时出错,如下所示:Php Zend\ServiceManager\ServiceManager::get无法获取或创建getAlbumTable的实例,php,zend-framework,module,Php,Zend Framework,Module,我正在尝试修改和复制一个自定义模块,我已经设置了DB connection的所有内容,但在查看我的模块时出错,如下所示: Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for getAlbumTable 以下是my module.config文件: return array( 'controllers' => array( 'invokables' =>
Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for getAlbumTable
以下是my module.config文件:
return array(
'controllers' => array(
'invokables' => array(
'Album\Controller\Album' => 'Album\Controller\AlbumController',
),
),
// The following section is new and should be added to your file
'router' => array(

下面是global.php中的数据库连接
return array(
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=stickynotes;host=localhost',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter'
=> 'Zend\Db\Adapter\AdapterServiceFactory',
),
),
);
以下是module.php中服务配置的代码:
public function getServiceConfig()
{
return array(
'factories' => array(
'Album\Model\AlbumTable' => function($sm) {
$tableGateway = $sm->get('AlbumTableGateway');
$table = new AlbumTable($tableGateway);
return $table;
},
'AlbumTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Album());
return new TableGateway('album', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
<?php
namespace Album\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
class AlbumController extends AbstractActionController
{
protected $_albumTable;
public function indexAction()
{
return new ViewModel(array(
'albums' => $this->getAlbumTable()->fetchAll(),
));
}
}
?>
这是获取相册的控制器:
public function getServiceConfig()
{
return array(
'factories' => array(
'Album\Model\AlbumTable' => function($sm) {
$tableGateway = $sm->get('AlbumTableGateway');
$table = new AlbumTable($tableGateway);
return $table;
},
'AlbumTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Album());
return new TableGateway('album', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
<?php
namespace Album\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
class AlbumController extends AbstractActionController
{
protected $_albumTable;
public function indexAction()
{
return new ViewModel(array(
'albums' => $this->getAlbumTable()->fetchAll(),
));
}
}
?>
以下是数据库表的附件:
有人能告诉我在哪里调试这个错误并修复这个问题吗?当您调用
$this->getAlbumTable()
Zend查找控制器插件时,没有这样名称的插件,所以它抛出异常
如果您想从服务\u管理器
访问任何类,您必须通过工厂注入它
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use MyNamespace\Controller\AlbumController;
class AlbumControllerFactory implements FactoryInterface
{
/**
*
* @param ContainerInterface $container
* @param string $requestedName
* @param null|array $options
* @return AlbumController
*/
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
$class = $requestedName ? $requestedName : AlbumController::class;
$albumTable = $container->get('Album\Model\AlbumTable'); // get service from service manager
$controller = new $class($albumTable);
return $controller;
}
/**
* Provided for backwards compatibility; proxies to __invoke().
*
* @param ContainerInterface|ServiceLocatorInterface $container
* @return AlbumController
*/
public function createService(ServiceLocatorInterface $container)
{
return $this($container, AlbumController::class);
}
}
在
module.config.php中
'controllers' => array(
'factories' => array(
Controller\AlbumController::class => Factory\Controller\AlbumControllerFactory::class,
),
),
在控制器中:
namespace Album\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
class AlbumController extends AbstractActionController
{
protected $_albumTable;
public function __construct(AlbumTable $albumTable)
{
$this->_albumTable = $albumTable;
}
public function indexAction()
{
return new ViewModel(array(
'albums' => $this->_albumTable->fetchAll()
));
}
}
很简单,不是吗?:) 我刚刚通过在我的模块文件Module.php中添加服务解决了这个问题,现在it工作正常:
public function getServiceConfig()
{
return array(
'factories' => array(
'Album\Model\AlbumTable' => function($sm) {
$tableGateway = $sm->get('AlbumTableGateway');
$table = new AlbumTable($tableGateway);
return $table;
},
'AlbumTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Album());
return new TableGateway('album', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
似乎我们需要的所有代码都不存在。表的服务管理器配置在哪里?如何将表注入控制器中?(这里有一个可调用的,而不是工厂,所以不能注入…)。您使用的是ZF3还是ZF2?它是ZF2。您希望看到代码的哪一部分,因此我将更新问题@Thomas Dutrion,该问题主要是配置文件中的任何service\u manager
键,以及任何->get(
代码中的任何位置(应主要在工厂中).显示调用getAlbumTable的位置和方式
代码的第一部分将落在哪里,表示我的模块的哪个文件?@szymonm此行抛出错误,不让代码运行,$class=$requestedName?$requestedName:AlbumController::class;给出此错误:Controller:Album\Controller\Album(解析为无效的控制器类或别名:Album\controller\Album)在尝试创建controlleralbumcontroller(别名:controller\AlbumController)时,在中的module.config.php
中路由更改controller'=>“Album\Album
到controller=>controller\AlbumController::class
)为此实例类型注册了无效的工厂。:此错误是什么@SzymonM
