使用自定义操作的Api Platform错误的上下文响应

Question

我正在为项目使用API​​平台，并且自定义操作存在问题。我的动作的响应与我预期的输出不符。实际上，上下文中的某些元素并不适合我的要求。

她是我的代码示例

<?php

namespace App\Entity;

...

/**
 * @ORM\Table
 * @ORM\Entity
 *
 * @ApiResource(
 *     itemOperations={
 *         "list_conversation"={"method"="GET", "path"="/users/{id}/conversations", "controller"="App\Action\Conversation\ConversationByUser", "access_control"="is_granted('ROLE_ADMIN') or object == user"}
 *})
 */
class User
{
   ...
}

<?php
namespace App\Action\Conversation;

use App\Entity\User;
use App\Entity\ConversationUser;
use Symfony\Bridge\Doctrine\RegistryInterface;

class ConversationByUser
{
    /**
     * @var RegistryInterface
     */
    protected $registry;

    /**
     * ConversationByUser constructor.
     * @param RegistryInterface $registry
     */
    public function __construct(RegistryInterface $registry)
    {
        $this->registry = $registry;
    }

    public function __invoke(string $id)
    {
        $emUser = $this->registry->getManagerForClass(User::class);

        $user = $emUser->getRepository(User::class)->findOneBy([
            'id' => $id
        ]);

        $emConversationUser = $this->registry->getManagerForClass(ConversationUser::class);

        $conversationUsers = $emConversationUser->getRepository(ConversationUser::class)->findBy([
            'user' => $user
        ]);

        $conversations = [];

        /** @var ConversationUser $conversationUser */
        foreach ($conversationUsers as $conversationUser) {
            $conversations[] = $conversationUser->getConversation();
        }

        return $conversations;
    }
}

我希望这个输出

    "@context": "/contexts/Conversation",
    "@id": "/users/{id}/conversations",
    "@type": "hydra:Collection",
    "hydra:member": [],
    "hydra:totalItems": 0,
    "hydra:search": {
       ...
    }

但实际输出是

    "@context": "/contexts/User",
    "@id": "/users",
    "@type": "hydra:Collection",
    "hydra:member": [],
    "hydra:totalItems": 0,
    "hydra:search": {
       ...
    }

我们可以看到 @context 和 @id

感谢您的帮助

Ps： 我尝试使用marv255解决方案，@ context正确更改，但是@id仍然为假。
