如何在不使用ZF2 ..中任何控制器对象的情况下访问module.php中的控制器插件？

我想在module.php中添加错误处理,以在Flash Messenger中添加所有错误消息并重定向到特定页面(根据我的要求)：

public function handleError(MvcEvent $e) {
        $exception = $e->getParam('exception');
        $controller = $e->getTarget();
        //echo $exception->getMessage(); exit;
        if (!$e->getApplication()->getServiceManager()->get('AuthService')->hasIdentity()) {
            $controller->flashMessenger()->addErrorMessage("Session Expired..!!");
            return $e->getTarget()->plugin('redirect')->toRoute('auth', array('action' => 'login'));
        }

        switch ($exception->getCode()) {
            case "2003" :
                $controller->flashMessenger()->addErrorMessage("Unable to connect database..!!");
                break;

            default :
                $controller->flashMessenger()->addErrorMessage($exception->getMessage());
                break;
        }

        $e->getApplication()->getServiceManager()->get('AuthService')->clearIdentity();
        return $e->getTarget()->plugin('redirect')->toRoute('auth', array('action' => 'login'));
    }

但是在某些错误中,它会抛出对$e-> getTarget()上未定义方法插件的调用,因为在某些情况下,错误是在插件绑定之前生成的.我想要一种无需引用任何控制器即可访问重定向和Flash Messenger插件的方法.

解决方法:

在尝试了多种在google上定义的方法后,我发现以下工作方式：

public function handleError(MvcEvent $e) {

        $exception = $e->getParam('exception');
        $sm = $e->getApplication()->getServiceManager();
        $flashmessenger = $sm->get('ControllerPluginManager')->get('flashmessenger');
        //echo $exception->getMessage(); exit;
        if (!$e->getApplication()->getServiceManager()->get('AuthService')->hasIdentity()) {
            $flashmessenger->addErrorMessage("Session Expired..!!");
            return $sm->get('ControllerPluginManager')->get('redirect')->toRoute('auth', array('action' => 'login'));
        }

        switch ($exception->getCode()) {
            case "2003" :
                $flashmessenger->addErrorMessage("Unable to connect database..!!");
                break;

            default :
                $flashmessenger->addErrorMessage($exception->getMessage());
                break;
        }

        $e->getApplication()->getServiceManager()->get('AuthService')->clearIdentity();
        return $sm->get('ControllerPluginManager')->get('redirect')->toRoute('auth', array('action' => 'login'));
    }

我在这里发布了这些解决方案,这样可以节省其他人再次搜索的时间.
