error-handling - 如何在Zend Framework 2中将变量传递到错误 View 脚本？

Question

我捕获了特定于框架的异常，如下所示:

public function onBootstrap(MvcEvent $e)
{
    $eventManager = $e->getApplication()->getEventManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);
    ...
    $sharedManager = $e->getApplication()
        ->getEventManager()
        ->getSharedManager();
    $sm = $e->getApplication()->getServiceManager();
    $sharedManager->attach('Zend\Mvc\Application', MvcEvent::EVENT_DISPATCH_ERROR, 
        function ($e) use($sm) {
            if ($e->getParam('exception')) {
                $sm->get('Logger')
                    ->crit($e->getParam('exception'));
            }
            // trying to pass a variable
            $e->getViewModel()->setVariable('foo', 'bar');
        });
}

然后，当我尝试访问 $foo中的 /module/Application/view/error/index.phtml时，我得到了 Notice: Undefined variable: foo。

如何将变量传递到错误 View 脚本并在那里访问它？

从onBootstrap内部，它将变量传递到布局。

尝试这个:

$this->layout()->foo
