drupal_access_denied()
已从AccessDeniedHttpException类替换。需要返回“访问被拒绝”错误的页面回调应使用与以下代码相似的代码。
// system_batch_page()
public function batchPage(Request $request) {
require_once $this->root . '/core/includes/batch.inc';
$output = _batch_page($request);
if ($output === FALSE) {
throw new AccessDeniedHttpException();
}
elseif ($output instanceof Response) {
return $output;
}
elseif (isset($output)) {
$title = isset($output['#title']) ? $output['#title'] : NULL;
$page = [
'#type' => 'page',
'#title' => $title,
'#show_messages' => FALSE,
'content' => $output,
];
// Also inject title as a page header (if available).
if ($title) {
$page['header'] = [
'#type' => 'page_title',
'#title' => $title,
];
}
return $page;
}
}
代替的drupal_get_query_array()
有parse_query()
(在一个功能GuzzleHttp\Psr7
命名空间),这是狂饮的一部分。
drupal_goto()
已从RedirectResponse
班级替换。需要重定向用户的页面回调应使用类似于以下代码的代码。(请注意,表单提交处理程序不应使用此类。)
// AddSectionController::build()
public function build(SectionStorageInterface $section_storage, $delta, $plugin_id) {
$section_storage
->insertSection($delta, new Section($plugin_id));
$this->layoutTempstoreRepository
->set($section_storage);
if ($this->isAjax()) {
return $this->rebuildAndClose($section_storage);
}
else {
$url = $section_storage->getLayoutBuilderUrl();
return new RedirectResponse($url->setAbsolute()->toString());
}
}
drupal_http_request()
已从实现ClientInterface接口的Drupal 8服务中替换。Drupal 8代码应类似于以下代码。
// system_retrieve_file()
try {
$data = (string) \Drupal::httpClient()->get($url)->getBody();
$local = $managed ? file_save_data($data, $path, $replace) : file_unmanaged_save_data($data, $path, $replace);
} catch (RequestException $exception) {
\Drupal::messenger()->addError(t('Failed to fetch file due to error "%error"', ['%error' => $exception->getMessage()]));
return FALSE;
}
drupal_not_found()
已从NotFoundHttpException类替换。页面回调应使用类似于以下代码的代码。
// BookController::bookExport()
public function bookExport($type, NodeInterface $node) {
$method = 'bookExport' . Container::camelize($type);
// @todo Convert the custom export functionality to serializer.
if (!method_exists($this->bookExport, $method)) {
$this->messenger()->addStatus(t('Unknown export format.'));
throw new NotFoundHttpException();
}
$exported_book = $this->bookExport->{$method}($node);
return new Response($this->renderer->renderRoot($exported_book));
}
drupal_site_offline()
应该由事件订阅者代替,类似于下一个。
public static function getSubscribedEvents() {
$events[KernelEvents::REQUEST][] = ['onKernelRequestMaintenance', 30];
$events[KernelEvents::EXCEPTION][] = ['onKernelRequestMaintenance'];
return $events;
}
public function onKernelRequestMaintenance(GetResponseEvent $event) {
$request = $event->getRequest();
$route_match = RouteMatch::createFromRequest($request);
if ($this->maintenanceMode->applies($route_match)) {
// Don't cache maintenance mode pages.
\Drupal::service('page_cache_kill_switch')->trigger();
if (!$this->maintenanceMode->exempt($this->account)) {
// Deliver the 503 page if the site is in maintenance mode and the
// logged in user is not allowed to bypass it.
// If the request format is not 'html' then show default maintenance
// mode page else show a text/plain page with maintenance message.
if ($request->getRequestFormat() !== 'html') {
$response = new Response($this->getSiteMaintenanceMessage(), %03, ['Content-Type' => 'text/plain']);
$event->setResponse($response);
return;
}
drupal_maintenance_theme();
$response = $this->bareHtmlPageRenderer->renderBarePage([ '#markup' => $this->getSiteMaintenanceMessage()], $this->t('Site under maintenance'), 'maintenance_page');
$response->setStatusCode(503);
$event->setResponse($response);
}
else {
// Display a message if the logged in user has access to the site in
// maintenance mode. However, suppress it on the maintenance mode
// settings page.
if ($route_match->getRouteName() != 'system.site_maintenance_mode') {
if ($this->account->hasPermission('administer site configuration')) {
$this->messenger->addMessage($this
->t('Operating in maintenance mode. <a href=":url">Go online.</a>', [':url' => $this->urlGenerator->generate('system.site_maintenance_mode')]), 'status', FALSE);
}
else {
$this->messenger->addMessage($this->t('Operating in maintenance mode.'), 'status', FALSE);
}
}
}
}
}
