我使用 PHP - Symfony 5。
我想在 API 平台上返回一个带有 graphQL 的集合，但我有一个问题：
"debugMessage": "Service "App\DataProvider\CompaniesCollectionDataProvider" not found: the container inside "Symfony\Component\DependencyInjection\Argument\ServiceLocator" is a smaller service locator that only knows about the "App\Resolver\CheckRecruiterQueryResolver", "App\Resolver\ForgotRecruiterQueryResolver" and "App\Resolver\JobBoard\FindOffersByCompanyQueryResolver" services.",
首先，我创建了一个解析器，但查看文档后，我意识到有必要创建一个数据提供程序。
不幸的是，这并没有解决问题，我仍然有相同的错误消息......
我的自定义数据提供程序：
namespace AppDataProvider;
use ApiPlatformCoreDataProviderCollectionDataProviderInterface;
use AppEntityCandidate;
use AppEntityCompany;
use DoctrinePersistenceManagerRegistry;
class CompaniesCollectionDataProvider implements CollectionDataProviderInterface
{
private $doctrine;
public function __construct(ManagerRegistry $doctrine)
{
$this->doctrine = $doctrine;
}
public function getCollection
(string $resourceClass, string $operationName = null, array $context = [])
{
$candidateId = $context['filters']['candidate_id'];
$candidate = $this->doctrine->getRepository(Candidate::class)
->findOneBy(['id' => $candidateId]);
if(empty($candidate->getPosition()))
{
$companies = $this->doctrine->getRepository(Company::class)
->findByStoreIsNational();
// return companies where stores related = is_national
// getCollection doit retourner un array
return $companies;
}
$companies = $this->doctrine->getRepository(Company::class)
->findByStoreIsNational();
return $companies;
}
}
我的实体 ：

}
我提前感谢您的帮助，

如自定义查询的文档中所述，您需要创建自定义解析程序，而不是自定义数据提供程序。
CompaniesCollectionDataProvider应该变得CompanyCollectionResolver，应该实施QueryCollectionResolverInterface。
