Zend Framework 2实现会话的最佳方式

I have a code like this:

        $sessionOptions = new SessionDbSavehandlerOptions();
        $sessionOptions->setDataColumn('data')
                       ->setIdColumn('id')
                       ->setModifiedColumn('modified')
                       ->setLifetimeColumn('lifetime')
                       ->setNameColumn('name');
        $application    = $event->getApplication();
        $serviceManager = $application->getServiceManager();
        $dbAdapter = $serviceManager->get('Zend\Db\Adapter\Adapter');
        $sessionTableGateway = new TableGateway('zf2_sessions', $dbAdapter);
        $sessionGateway = new DbTableGateway($sessionTableGateway, $sessionOptions);
        $config = $serviceManager->get('Configuration');
        $sessionConfig = new SessionConfig();
        $sessionConfig->setOptions($config['session']);
        $sessionManager = new SessionManager($sessionConfig);
        $sessionManager->setSaveHandler($sessionGateway);
        $sessionManager->start();
        Container::setDefaultManager($sessionManager);

works good but this code is in onBootstrap() method in Module.php file. Is there a better way (place?) to implement session? Controller plugins are for Controller, so what is for these?

图片转代码服务由CSDN问答提供 功能建议

我有这样的代码:

  $ sessionOptions =  new SessionDbSavehandlerOptions(); 
 $ sessionOptions-> setDataColumn('data')
  - > setIdColumn('id')
  - > setModifiedColumn('modified')
  - > setLifetimeColumn('lifetime'  )
  - > setNameColumn('name'); 
 $ application = $ event-> getApplication(); 
 $ serviceManager = $ application-> getServiceManager(); 
 $ dbAdapter = $ serviceManager-&gt  ; get('Zend \ Db \ Adapter \ Adapter'); 
 $ sessionTableGateway = new TableGateway('zf2_sessions',$ dbAdapter); 
 $ sessionGateway = new DbTableGateway($ sessionTableGateway,$ sessionOptions); 
 $ config =  $ serviceManager-> get('Configuration'); 
 $ sessionConfig = new SessionConfig(); 
 $ sessionConfig-> setOptions($ config ['session']); 
 $ sessionManager = new SessionManager($ sess  ionConfig); 
 $ sessionManager-> setSaveHandler($ sessionGateway); 
 $ sessionManager-> start(); 
 Container :: setDefaultManager($ sessionManager); 
   
  
 

工作正常,但此代码位于 Module.php 文件中的 onBootstrap()方法中。 是否有更好的方法(地点?)来实现会话? 控制器插件适用于Controller,那么这些是什么?

    My suggestion would be to make this a dedicated, low level module. You can encapsulate the complete configuration and instantiation into a simple module which you can depend on for your further application.

    It is quite the same as we handle our mail, logging and cache (though cache is not complete yet). In those cases we create services which we can inject in our application services. In your case, I would make it a listener (encapsuled in a dedicated class or not) where you initialize it in your onBootstrap() method.

    A small example:

    namespace MySession;
    
    use Zend\Session\Container;
    
    class Module
    {
        public function onBootstrap($e)
        {
            $app = $e->getApplication();
            $sm  = $app->getServiceManager();
    
            $manager = $sm->get('session_manager');
            $manager->start();
    
            Container::setDefaultManager($manager);
        }
    
        public function getServiceConfig()
        {
            return array(
                'factories' => array(
                    'session_manager' => 'MySession\Service\SessionManagerFactory'
                ),
            );
        }
    }
    

    And you encapsulate the session manager's factory logic in a factory class:

    namespace MySession\Service;
    
    use Zend\ServiceManger\FactoryInterface;
    use Zend\ServiceManager\ServiceLocatorInterface;
    
    // Your imports further here
    
    class SessionManagerFactory implements FactoryInterface
    {
        public function createService(ServiceLocatorInterface $sl)
        {
            $sessionOptions = new SessionDbSavehandlerOptions();
            $sessionOptions->setDataColumn('data')
                           ->setIdColumn('id')
                           ->setModifiedColumn('modified')
                           ->setLifetimeColumn('lifetime')
                           ->setNameColumn('name');
            $application    = $event->getApplication();
            $serviceManager = $application->getServiceManager();
            $dbAdapter = $serviceManager->get('Zend\Db\Adapter\Adapter');
            $sessionTableGateway = new TableGateway('zf2_sessions', $dbAdapter);
            $sessionGateway = new DbTableGateway($sessionTableGateway, $sessionOptions);
            $config = $serviceManager->get('Configuration');
            $sessionConfig = new SessionConfig();
            $sessionConfig->setOptions($config['session']);
            $sessionManager = new SessionManager($sessionConfig);
            $sessionManager->setSaveHandler($sessionGateway);
    
            return $sessionManager;
        }
    }
