用symfony序列化程序錯誤序列化

Question

我想使用symfony/serializer將我的實體序列化爲json。 我想要得到的東西像

{ 
    "id" : "string", 
    "name" : "name here", 
    "admin": "admin_id" 
    } 

但我總是最後一棵完整的樹 - 生成的JSON包含所有相關實體與它們之間的關係。我相信它必須是symfony/serializer的小任務，顯然是做錯了什麼，但是什麼？

CarbonNormalizer只是返回nesbot /碳對象的字符串表示形式。

這裏是我的控制器：

$data=$this->em->getRepository('Cpa:Cpa')->findAll(); 
    $encoder = new JsonEncoder(); 
    $normalizer = new GetSetMethodNormalizer();//object -same 
    $dateTimeNormalizer = new CarbonNormalizer(); 
    $normalizer->setCircularReferenceHandler(function ($object) { 
     return $object->getId(); 
    }); 
    $this->serializer = new Serializer([$dateTimeNormalizer, $normalizer], [$encoder]); 

    $data = $this->serializer->serialize($data, 'json', ['groups' => ['show'], 'enable_max_depth' => true]); 
    return new JsonResponse($data, $code, [], true); 

而且我的實體：

<?php 

namespace Domain\Cpa\Models; 


use Domain\Offer\Models\CpaOffer; 
use Domain\User\Models\User; 
use Ramsey\Uuid\Uuid; 

class Cpa 
{ 
/** @var string */ 
private $id; 

/** @var string */ 
private $name; 

/** @var User */ 
private $admin; 

/** @var CpaOffer[] */ 
private $offers; 

/** 
* Cpa constructor. 
* @param string $name 
* @param User $admin 
*/ 
public function __construct($name, User $admin) 
{ 
    $this->id = Uuid::uuid4()->toString(); 
    $this->name = $name; 
    $this->admin = $admin; 
    $this->offers = []; 
} 

/** 
* @return string 
*/ 
public function getId(): string 
{ 
    return $this->id; 
} 

/** 
* @return string 
*/ 
public function getName(): string 
{ 
    return $this->name; 
} 

/** 
* @return User 
*/ 
public function getAdmin(): User 
{ 
    return $this->admin; 
} 

/** 
* @return CpaOffer[] 
*/ 
public function getOffers()//: array 
{ 
    return $this->offers; 
} 

}

serialization.yml

Domain\Cpa\Models\Cpa: 
attributes: 
    id: 
    groups: ['show'] 
    name: 
    groups: ['show'] 
    admin: 
    groups: ['show']

要使用組，則需要初始化ClassMetadataFactory太：

// Don't forget to add the new use statements 
// ... 
$normalizer = new GetSetMethodNormalizer(
    new ClassMetadataFactory(
    new YamlFileLoader('/the/path/to/yourfile.yaml') 
) 
); 
// ... 

還必須解決您的YAML文件的縮進：

'Domain\Cpa\Models\Cpa': 
    attributes: 
    id: 
     groups: ['show'] 
    name: 
     groups: ['show'] 
    admin: 
     groups: ['show']
