我的问题很简单，我想在json中返回一个用于api的数组（使用JsonResponse）：
我给你一个我开始做的事的例子：
我的json响应：
{
"success": "true",
"message": "Liste du Profil",
"id": 54,
"username": "TestTest7",
"phone": null,
"email": "noemail@gmail.com",
"resume": "TestTest7",
"language": null,
"friends_added": [
{
"id_friend": {}
}
],
"friends_accepted": [],
"friends_added_need_to_be_accept": [
{
"id_friend": {}
}
],
"friends_need_to_be_accept": []
}
如您所见，这不是我想要的，因为这些字段是空的：id_friend也作为数据库friends_added_need_to_be_accept中的内容，但是其他两个数据库都为空。
我的控制器：
/**

* @Rest\Post(
* path = "/profile/list",
* name = "api_profile_list"
* )
* @Rest\View(StatusCode=201, serializerGroups={"user_detail"})

$em = $this->getDoctrine()->getManager();

$token = $request->get('token');
if (!isset($user)) {
return new JsonResponse([
'success' => "false",
'message' => "Utilisateur non renseigné"
]);
}
if (!isset($token)) {

}
if ($user->getToken() != $token) {

}
我的个人资料实体：

和我的朋友实体：

* })
*/
protected $user_one;
/**
* @var \AppBundle\Entity\User
*
* @ORM\GeneratedValue(strategy="NONE")
* @ORM\ManyToOne(targetEntity="User")
* @ORM\JoinColumns({
* @ORM\JoinColumn(name="user_id_two", referencedColumnName="id")
* })
*/
protected $user_two;
/**
* @var integer
*
* @ORM\Column(name="enabled", type="integer", nullable=false)
*/
private $enabled;
/**
* @return int
*/
public function getEnabled()
{
return $this->enabled;
}
/**
* @param int $enabled
*/
public function setEnabled($enabled)
{
$this->enabled = $enabled;
}
/**
* @return User
*/
public function getUserTwo()
{
return $this->user_two;
}
/**
* @param User $user_two
*/
public function setUserTwo($user_two)
{
$this->user_two = $user_two;
}
/**
* @return User
*/
public function getUserOne()
{
return $this->user_one;
}
/**
* @param User $user_one
*/
public function setUserOne($user_one)
{
$this->user_one = $user_one;
}
/**
* @return int
*/
public function getId()
{
return $this->id;
}
/**
* @param int $id
*/
public function setId($id)
{
$this->id = $id;
}
}
我100％确定我的实体很好，并且当我要填充数组时会出现错误。
看看我何时做：
foreach($friend_1 as $friends_1) {
$arrayCollection_1[] = array(
'id_friend' => 4,
);
}
那让我回来了：
{
"success": "true",
"message": "Liste du Profil",
"id": 54,
"username": "TestTest7",
"phone": null,
"email": "noemail@gmail.com",
"resume": "TestTest7",
"language": null,
"friends_added": [
{
"id_friend": 4
}
],
"friends_accepted": [],
"friends_added_need_to_be_accept": [],
"friends_need_to_be_accept": []
}
感谢任何试图回答并询问您是否想要我可能会忘记的细节的人！

在将要序列化并以json格式（例如User）发送的实体类上实施jsonSerialize。例子
class Friend implements JsonSerializable {
// previous functions
/**
* Specify data which should be serialized to JSON
* @link http://php.net/manual/en/jsonserializable.jsonserialize.php
* @return mixed data which can be serialized by <b>json_encode</b>,
* which is a value of any type other than a resource.
* @since 5.4.0
*/
function jsonSerialize()
{
return array(
"id" => $this->id,
"enabled" => $this->enabled,
"user_one" => $this->user_one,
"user_two" => $this->user_two,
);
}
}
