ZF2 - 如何更改错误/ 404响应页面？不只是模板,而是设置新的ViewModel

Question

默认情况下,页面在Applicationmodule.config数组中设置如下:

'template_map' => array(
    'error/404' => __DIR__ . '/../view/error/404.phtml'

我想改变页面.我想要新ViewModel的变量充满变数.这意味着仅仅更改模板是不够的:

'error/404' => __DIR__ . '/../view/error/my_new_404_template.phtml'

但我无法理解如何制作它.我无法看到请求的方式'error/404'.

• 如何ViewModel为它创造新的？

• 如何将变量附加到它？

• 如何通过路线来'error/404'改变它？

例如,我有这样的'error/404'页面方法:

public function pageNotFoundAction() {

    $view = new ViewModel();

    $view->setTemplate('error/404');     // set my template

    $sm = $this->getServiceLocator()->get('SessionManager');
    $cont = new Container('SomeNamespace', $sm);

    $view->var1 = $cont->offsetGet('someValue1');   // the "error/404" template
    $view->var2 = $cont->offsetGet('someValue2');   //       is full of variables
    $view->var3 = $cont->offsetGet('someValue3');
    $view->var4 = "One more view variable";

    // And now I return it somewhere and want it to be called
    //    in case of "the page is not found"
    return $view;
}

如何做出这样的改变？我无法得到他们创建的系统来处理类似的事情'error/404'.请帮忙.

更复杂的任务.怎么有几'error/404'页？想问一下创建框架的人是否知道'not_found_template'不能有一个'error/404'页面数组 .它怎么样？如果我像这样设置此选项:

'template_map' => array(
    'error/404' => __DIR__ . '/../view/error/404.phtml',
    'my-page/one_more_error404' => __DIR__ . '/../view/my-page/my-page/one_more_error404.phtml',
    'other_page/second_404' => __DIR__ . '/../view/other-page/one_more_error404.phtml',

'not_found_template' => array(
    'error/404',
    'my-page/one_more_error404',
    'other-page/second_404',
);

它会抛出一个错误.'not_found_template'强迫你只有一个'error/404'模板？

还有另一种方式.赶上EVENT_DISPATCH_ERROR并完全重建viewModel.洞穴是布局 - 是根viewModel,默认情况下附加到布局的内容是另一个viewModel(子).官方文档中没有明确说明这些要点.

以下是它在您的样子中的样子Module.php:

public function onBootstrap(MvcEvent $event)
{
    $app = $event->getParam( 'application' );
    $eventManager = $app->getEventManager();


    /** attach Front layout for 404 errors */
    $eventManager->attach( MvcEvent::EVENT_DISPATCH_ERROR, function( MvcEvent $event ){

        /** here you can retrieve anything from your serviceManager */
        $serviceManager = $event->getApplication()->getServiceManager();
        $someVar = $serviceManager->get( 'Some\Factory' )->getSomeValue();

        /** here you redefine layout used to publish an error */
        $layout = $serviceManager->get( 'viewManager' )->getViewModel();
        $layout->setTemplate( 'layout/start' );

        /** here you redefine template used to the error exactly and pass custom variable into ViewModel */
        $viewModel = $event->getViewModel();
        $viewModel->setVariables( array( 'someVar' => $someVar ) )
                  ->setTemplate( 'error/404' );
    });
}

我不确定我是否遵循您想要实现的目标，您能否给出一个明确的例子来说明您想要做什么？

如果您只是尝试将变量添加到传递的视图模型中，您甚至可以在控制器中执行此操作，请查看AbstractActionController

/**
 * Action called if matched action does not exist
 *
 * @return array
 */
public function notFoundAction()
{
    $response   = $this->response;
    $event      = $this->getEvent();
    $routeMatch = $event->getRouteMatch();
    $routeMatch->setParam('action', 'not-found');

    if ($response instanceof HttpResponse) {
        return $this->createHttpNotFoundModel($response);
    }
    return $this->createConsoleNotFoundModel($response);
}

/**
 * Create an HTTP view model representing a "not found" page
 *
 * @param  HttpResponse $response
 * @return ViewModel
 */
protected function createHttpNotFoundModel(HttpResponse $response)
{
    $response->setStatusCode(404);

    // Add in extra stuff from your ServiceLocator here...

    // $viewModel->setTemplate(..); 

    return new ViewModel(array(
        'content' => 'Page not found',
    ));
}
