I am facing this issue when i try to access REST endpoint through ajax get request. Important thing, when i was logged-in then every works find but when i am not logged it it through above exception.
Here is my code
namespace Drupalone_rest_apiPluginrestresource; use DrupalfileEntityFile; use DrupalimageEntityImageStyle; use Drupalmedia_entityEntityMedia; use DrupalnodeEntityNode; use DrupalrestPluginResourceBase; use DrupalrestResourceResponse; use DrupalCoreSessionAccountProxyInterface; use DrupaltaxonomyEntityTerm; use PsrLogLoggerInterface; use SymfonyComponentDependencyInjectionContainerInterface; use SymfonyComponentHttpKernelExceptionAccessDeniedHttpException; use SymfonyComponentHttpKernelExceptionHttpException; /** * Provides article resource endpoint * * @RestResource( * id = "one_article_resource", * label = @Translation("One Article Resource"), * uri_paths = { * "canonical" = "/api/one/v1/articles" * } * ) */ class ArticleResource extends ResourceBase { /** * A current user instance. * * @var DrupalCoreSessionAccountProxyInterface */ protected $currentUser; /** * Constructs a DrupalrestPluginResourceBase object. * * @param array $configuration * A configuration array containing information about the plugin instance. * @param string $plugin_id * The plugin_id for the plugin instance. * @param mixed $plugin_definition * The plugin implementation definition. * @param array $serializer_formats * The available serialization formats. * @param PsrLogLoggerInterface $logger * A logger instance. * @param DrupalCoreSessionAccountProxyInterface $current_user * A current user instance. */ public function __construct( array $configuration, $plugin_id, $plugin_definition, array $serializer_formats, LoggerInterface $logger, AccountProxyInterface $current_user) { parent::__construct($configuration, $plugin_id, $plugin_definition, $serializer_formats, $logger); $this->currentUser = $current_user; } /** * {@inheritdoc} */ public static function create(ContainerInterface $container, array $configuration, $plugin_id, $plugin_definition) { return new static( $configuration, $plugin_id, $plugin_definition, $container->getParameter('serializer.formats'), $container->get('logger.factory')->get('one_rest'), $container->get('current_user') ); } /** * Responds to GET requests. * * Returns a list of bundles for specified entity. * * @throws SymfonyComponentHttpKernelExceptionHttpException * Throws exception expected. */ public function get() { global $base_url; $response_result = []; $response_code = 200; // You must to implement the logic of your REST Resource here. // Use current user after pass authentication to validate access. if (!$this->currentUser->hasPermission('access content')) { throw new AccessDeniedHttpException(); } $entities = Drupal::entityQuery('node') ->condition('status', 1) ->condition('type', 'article') ->condition('langcode','en') ->notExists('field_f1') ->sort('created', 'DESC') ->range(0, 20) ->execute(); if(!empty($entities)){ foreach ($entities as $node_id) { $node = Node::load($node_id); if(is_object($node)){ $image_url = ''; $image_target = $node->get('field_image')->target_id; if(!empty($image_target)){ $media = Media::load($image_target); if(is_object($media)){ $image = File::load($media->get('field_image')->target_id); $image_url = ImageStyle::load('rest_api')->buildUrl($image->getFileUri()); } } $output_tags = []; $tags = $node->get('field_tags')->getValue(); if(!empty($tags)){ foreach($tags as $key => $tag){ $term = Term::load($tag['target_id']); $output_tags[] = $term->get('name')->value; } } $result = [ "nid" => $node->id(), "base_url" => $base_url, "title" => $node->getTitle(), "field_image" => $image_url, "field_tags" => $output_tags ]; $response_result[] = $result; } } } if(!empty($response_result)) { $headers = [ 'Access-Control-Allow-Origin' => '*', 'Access-Control-Allow-Methods' => 'POST, GET, OPTIONS, PATCH, DELETE', 'Access-Control-Allow-Headers' => 'Authorization' ]; $response = new ResourceResponse($response_result, $response_code, $headers); return $response; } throw new HttpException(t("Empty Response")); } } And Below is my typescript code
load(){ if(this.data){ return Promise.resolve(this.data); } return new Promise(resolve => { this.http.get('https://example.com/api/one/v1/articles?_format=json') .subscribe(data => { this.data = data; resolve(this.data); },err => { console.log(err); }); }); } I didn’t understand what i am missing in drupal code
