Zend Framework2 - 在 Module.php中检查管理是否登录，而不是到控制器中检查 (实现方法示例)

在ZF2中应使用事件驱动方法实现, 会影响所有模块？

是否只仅作用于当前模块？

>>方法一

(This should be done with event in ZF2 for more details:

click here(参考官方方法http://framework.zend.com/manual/2.0/en/modules/zend.event-manager.event-manager.html)

also this code may help you. http://pastebin.com/FFGVCpki)
public function init() {

// Attach Event to EventManager

$events = StaticEventManager::getInstance ();

// Add event of authentication before dispatch

$events->attach ( 'Zend\Mvc\Controller\AbstractActionController', 'dispatch', array (

$this,

'authPreDispatch'

), 110 );

}

public function authPreDispatch($event){

$target = $event->getTarget ();

$serviceLocator = $target->getServiceLocator();

// Do what ever you want to check the user's identity

$url = $event->getRouter ()->assemble ( array (

"controller" => "<controller>"

), array (

'name' => '<route name>'

) );

$response = $event->getResponse ();

$response->setHeaders ( $response->getHeaders ()->addHeaderLine ( 'Location', $url ) ));

$response->setStatusCode ( 302 );

$response->sendHeaders ();

exit ();

}

>>方法二：

//filename : SanAuthWithDbSaveHandler/Module.php

namespace SanAuthWithDbSaveHandler;

use Zend\Mvc\MvcEvent;

class Module

{

public function onBootstrap(MvcEvent $e)

{

$em = $e->getApplication()->getEventManager();

$em->attach('route', array($this, 'checkAuthenticated'));

}

public function isOpenRequest(MvcEvent $e)

{

if ($e->getRouteMatch()->getParam('controller') == 'SanAuthWithDbSaveHandler\Controller\AuthController') {

return true;

}

return false;

}

public function checkAuthenticated(MvcEvent $e)

{

if (!$this->isOpenRequest($e)) {

$sm = $e->getApplication()->getServiceManager();

if (! $sm->get('AuthService')->getStorage()->getSessionManager()

->getSaveHandler()->read($sm->get('AuthService')->getStorage()->getSessionId())) {

$e->getRouteMatch()

->setParam('controller', 'SanAuthWithDbSaveHandler\Controller\Auth')

->setParam('action', 'index');

}

}

}

>> ---------- 根据MVC $e获取tabelGateway -----------------

$e->getApplication()->getServiceManager()->get('Admin\Model\ModsTable')->sideBar()

' Admin\Model\ModsTable' 在public function getServiceConfig() 中配置注入

public function getConfig()

{

return include __DIR__ . '/config/module.config.php';

}

}
