自定义存储库上带有 ApiPlatform 的分页器

Question

我想在我的回复中包含 hydra:totalItems 和 hydra:view，所以我遵循了文档 https://api-platform.com/docs/core/pagination/#custom-controller-action 但我遇到了这个错误 "The controller must return a "Symfony\Component\HttpFoundation\Response" 对象，但它返回类型为 ApiPlatform\Core\Bridge\Doctrine\Orm\Paginator 的对象。"

<?php

namespace App\Controller;

use ApiPlatform\Core\Bridge\Doctrine\Orm\Paginator;
use App\Repository\ProductRepository;
use App\Repository\TermRelationshipsRepository;
use Doctrine\Common\Persistence\ObjectManager;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class FakeAction extends AbstractController
{
    private $termRelationshipsRepository;

    public function __construct(TermRelationshipsRepository $termRelationshipsRepository)
    {
        $this->termRelationshipsRepository = $termRelationshipsRepository;
    }

    /**
     * @Route(
     *     name="api_fake_action",
     *     path="/api/fake"
     * )
     */
    public function __invoke(): Paginator
    {
        return $this->termRelationshipsRepository->findAllProductsIdsByTerm_id(126);
    }
}

<?php

namespace App\Repository;

use App\Entity\TermRelationships;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Common\Collections\Criteria;
use Doctrine\ORM\Tools\Pagination\Paginator as DoctrinePaginator;
use ApiPlatform\Core\Bridge\Doctrine\Orm\Paginator;
use Symfony\Bridge\Doctrine\RegistryInterface;

/**
 * @method TermRelationships|null find($id, $lockMode = null, $lockVersion = null)
 * @method TermRelationships|null findOneBy(array $criteria, array $orderBy = null)
 * @method TermRelationships[]    findAll()
 * @method TermRelationships[]    findBy(array $criteria, array $orderBy = null, $limit = null, $offset = null)
 */
class TermRelationshipsRepository extends ServiceEntityRepository
{
    const ITEMS_PER_PAGE = 5;

    public function __construct(RegistryInterface $registry)
    {
        parent::__construct($registry, TermRelationships::class);
    }

    public function findAllProductsIdsByTerm_id($term_id, $array_result = false, $offset = 1, $nb_result = 23) : Paginator
    {
        $firstResult = (1 - $offset) * self::ITEMS_PER_PAGE;

        $queryBuilder = $this->createQueryBuilder('p');
        $queryBuilder
            ->andWhere('p.termTaxonomyId = :termTaxonomyId')
            ->setParameter('termTaxonomyId', $term_id)
        ;

        $criteria = Criteria::create()
            ->setFirstResult($firstResult)
            ->setMaxResults(self::ITEMS_PER_PAGE);
        $queryBuilder->addCriteria($criteria);

        $doctrinePaginator = new DoctrinePaginator($queryBuilder);
        $paginator = new Paginator($doctrinePaginator);

        return $paginator;
    }
}

已解决！我忘了它是注释中的默认参数

/**
 * @Route(
 *     name="api_fake_action",
 *     path="/api/fake",
 *     defaults={
 *         "_api_resource_class"=FakeEntity::class,
 *         "_api_collection_operation_name"="post_publication"
 *     }
 * )
 */
public function __invoke(): Paginator
{
    return $this->termRelationshipsRepository->findAllProductsIdsByTerm_id(126);
}

编辑：我制作了一个 repo，展示了如何在原始数据（使用 csv 文件）上使用 api 平台以及如何对其进行过滤、排序和保持分页. https://github.com/aratinau/api-platform-pagination
