Question

我有一条名为student的路线，就像这样

'student' => array(
 'type' => 'Hostname',
   'options' => array(
     'route' => ':subdomain.domain.com',
     'constraints' => array(
       'subdomain' => '([a-zA-Z0-9]*)'
         ...

我的一些模块中有子路径。我需要在执行此子路由的任何操作之前运行一个函数（例如checkSubdomain（））。

任何人都可以帮助我？

谢谢你们！我的代码现在：

public function onBootstrap(MvcEvent $e)
{
    $eventManager        = $e->getApplication()->getEventManager();

    $eventManager->attach(MvcEvent::EVENT_ROUTE, array($this, 'checkSubdomain'));
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);
}

public function checkSubdomain(EventInterface $e) {
    $app = $e->getApplication();
    $sm = $app->getServiceManager();
    $routeMatch = $e->getRouteMatch();
    $matchedRouteName = $routeMatch->getMatchedRouteName();


    $arr = explode('/',$matchedRouteName);
    if ($arr[0]=='student') {
        $subdomain = $routeMatch->getParam('subdomain');
        $em = $sm->get('project_entitymanager');
        $proj = $em->getRepository('Project\Entity\Project')->findOneBy(array('subdomain' => $subdomain));

        if (!$proj) $e->stopPropagation();
    }
}

Answer 1

根据“检查”中实际需要完成的操作，我会将事件监听器附加到MvcEvent::EVENT_ROUTE事件或MvcEvent::EVENT_DISPATCH

例如

// Module.php
public function onBootstrap(MvcEvent $event) {
  $application  = $event->getApplication();
  $eventManager = $application->getEventManager();

  $eventManager->attach(MvcEvent::EVENT_ROUTE, array($this, 'checkSubdomain'));
} 

public function checkSubdomain(EventInterface $event) {
   // Use $event to fetch the required event criteria
   // and 'check' sub domain here
}

您可以在Module班级init功能中执行此操作。在module/Application/Module.php和init

ZF2在某些模块中的子路由之前执行功能
