我想在插件类中获取服务定位器/实体管理器,我该怎么做呢.
在我的控制器中,我得到这样的.
public function getEntityManager()
{
if(null === $this->em){
$this->em = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');
}
return $this->em;
}
public function setEntityManager(EntityManager $em)
{
$this->em = $em;
}
但是在插件类中,我在$this-> getServiceLocator()行上收到错误.因为这在插件类中不可用.
我怎样才能这样做,以便我可以获取一些记录并在插件中插入少量数据库.
我的插件类中有MvcEvent $e对象,我可以利用它来获取实体管理器吗？
我用this plugin来创建我的插件
任何指南都会受到关注.
更新：
namespace Auth\Controller\Plugin;
use Zend\Mvc\Controller\Plugin\AbstractPlugin;
use Zend\EventManager\EventInterface as Event;
use Zend\Authentication\AuthenticationService;
use Doctrine\ORM\EntityManager;
use Auth\Entity\User;
use Zend\Mvc\MvcEvent;
class AclPlugin extends AbstractPlugin
{
/*
* @var Doctrine\ORM\EntityManager
*/
protected $em;
public function checkAcl($e)
{
$auth = new AuthenticationService();
if ($auth->hasIdentity()) {
$storage = $auth->getStorage()->read();
if (!empty($storage->role))
$role = strtolower ( $storage->role );
else
$role = "guest";
} else {
$role = "guest";
}
$app = $e->getParam('application');
$acl = new \Auth\Acl\AclRules();
$matches = $e->getRouteMatch();
$controller = $matches->getParam('controller');
$action = $matches->getParam('action','index');
$resource = strtolower( $controller );
$permission = strtolower( $action );
if (!$acl->hasResource($resource)) {
throw new \Exception('Resource ' . $resource . ' not defined');
}
if ($acl->isAllowed($role,$resource,$permission)) {
$query = $this->getEntityManager($e)->createQuery('SELECT u FROM Auth\Entity\User u');
$resultIdentities = $query->execute();
var_dump($resultIdentities);
exit();
return;
} else {
$matches->setParam('controller','Auth\Controller\User'); // redirect
$matches->setParam('action','accessdenied');
return;
}
}
public function getEntityManager($e) {
var_dump($this->getController()); // returns null
exit();
if (null === $this->em) {
$this->em = $this->getController()->getServiceLocator()->get('doctrine.entitymanager.orm_default');
}
return $this->em;
}
public function setEntityManager(EntityManager $em) {
$this->em = $em;
}
}
public function onBootstrap(Event $e)
{
$application = $e->getApplication();
$services = $application->getServiceManager();
$eventManager = $e->getApplication()->getEventManager();
$eventManager->attach('dispatch',array($this,'loadConfiguration'),101);
}
public function loadConfiguration(MvcEvent $e)
{
$e->getApplication()->getServiceManager()
->get('ControllerPluginManager')->get('AclPlugin')
->checkAcl($e); //pass to the plugin...
}
return array(
'controllers' => array(
'invokables' => array(
'Auth\Controller\User' => 'Auth\Controller\UserController',),'controller_plugins' => array(
'invokables' => array(
'AclPlugin' => 'Auth\Controller\Plugin\AclPlugin',);
你对“插件类”有什么意思？如果你正在谈论abount控制器插件,你可以使用(从控制器插件的范围)访问它：$this-> getController() – > getServiceLocator() – > get(‘doctrine.entitymanager.orm_default’) ;.
对于其他类,我通常会创建一个自动注入ServiceManager实例的工厂.例如,在Module类中：
public function getServiceConfig()
{
return array(
'factories' => array(
'myServiceClass' => function(ServiceManager $sm) {
$instance = new Class();
$instance->setServiceManager($sm);
// Do some other configuration
return $instance;
},);
}
// access it using the ServiceManager where you need it
$myService = $sm->get('myService');
