ApiPlatform - 创建自定义端点

Question

我尝试使用 api 平台创建一个 search 端点。客户端应通过 SearchInput::class（序列化）发送搜索查询，然后我将使用 elasticSearch 对另一个实体执行搜索，添加我自己的逻辑并使用 SearchOutput::class 作为响应（反序列化）。

该实体与数据库无关，所以我使用 DTO

我遵循了文档 https://api-platform.com/docs/core/controllers/ 但实际上我遇到了以下错误

The controller for URI \"/api/search\" is not callable: Controller \"PostSearchController\" does neither exist as service nor as class.

消息非常明确，但我不知道为什么会发生以及如何解决它。

App\Entity\Search.php

<?php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use App\Controller\PostSearchController;
use App\Dto\SearchInput;
use App\Dto\SearchOutput;

/**
 * @ApiResource(
 *   input=SearchInput::class,
 *   output=SearchOutput::class,
 *   collectionOperations = {
 *     "search" = {
 *       "method" = "POST",
 *       "path" = "/search",
 *       "controller" = "PostSearchController::class"
 *     }
 *  },
 *  itemOperations = {
 *
 *  }
 * )
 */
final class Search
{
    public $id;
}

App\Controller\PostSearchController.php

<?php

namespace App\Controller;

use App\Entity\Search;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

class PostSearchController extends AbstractController
{
    public function __invoke(Search $data): Search
    {
        var_dump($data);die;
    }
}

解决方案是在 ApiResource 注释中使用 FQCN

<?php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;

/**
 * @ApiResource(
 *   input="App\Dto\SearchInput",
 *   output="App\Dto\SearchOutput",
 *   collectionOperations = {
 *     "search" = {
 *       "method" = "post",
 *       "path" = "/search",
 *       "controller" = "App\Controller\PostSearchController"
 *     }
 *  },
 *  itemOperations = {
 *
 *  }
 * )
 */
final class Search
{
    public $id;
}
