实施REST API Symfony 3

Question

I have an existing Symfony 3 app. I installed FOSRestBundle, FOSUserBundle, NelmioCorsBundle. For example, I have 2 entity: User and Tariff.

The tariff has id, name, price, description, image, user (OneToMany to User) fields. The User has id, email, created, updated, some one-to-many fields, tariff (ManyToOne to Tariff).

I try to create UserRestController::getUserTariff:

    /**
 * @Rest\Get(path="/users/{id}/tariff", name="get_user_tariff")
 *
 * @param $id
 * @return Response
 */
public function getUserTariff($id)
{
    /** @var User $user */
    $user = $this->getDoctrine()->getRepository(User::class)->find($id);
    $tariff = $this->getDoctrine()->getRepository(Tariff::class)->findBy(['id' => $user->getTariff()->getId()]);

    $encoders = [new JsonEncoder()];
    $normalizers = [new ObjectNormalizer()];
    $serializer = new Serializer($normalizers, $encoders);

    $response = new JsonResponse($serializer->serialize($tariff, 'json'));
    $response->headers->set('Content-Type', 'application/json');

    return $response;
}

As a result of a request I have the following JSON:

"[{\u0022id\u0022:3,\u0022name\u0022:\u0022\\u041f\\u0440\\u043e\\u0434\\u0432\\u0438\\u043d\\u0443\\u0442\\u044b\\u0439\u0022,\u0022price\u0022:7900,\u0022description\u0022:null,\u0022leadMonthLimit\u0022:3000,\u0022status\u0022:100,\u0022active\u0022:true,\u0022comingSoon\u0022:false,\u0022image\u0022:\u0022advanced.jpg\u0022,\u0022user\u0022:null,\u0022deleted\u0022:false,\u0022product\u0022:{\u0022name\u0022:\u0022\\u0410\\u0431\\u043e\\u043d\\u0435\\u043d\\u0442\\u0441\\u043a\\u0430\\u044f \\u043f\\u043b\\u0430\\u0442\\u0430 \\u043f\\u043e \\u0442\\u0430\\u0440\\u0438\\u0444\\u0443 \\u00ab\\u041f\\u0440\\u043e\\u0434\\u0432\\u0438\\u043d\\u0443\\u0442\\u044b\\u0439\\u00bb\u0022,\u0022description\u0022:\u0022\\u0414\\u0430\\u043d\\u043d\\u044b\\u0439 \\u0442\\u0430\\u0440\\u0438\\u0444 \\u043f\\u043e\\u0437\\u0432\\u043e\\u043b\\u044f\\u0435\\u0442 \\u043e\\u0431\\u0440\\u0430\\u0431\\u0430\\u0442\\u044b\\u0432\\u0430\\u0442\\u044c \\u0434\\u043e 3000 \\u043a\\u043e\\u043d\\u0442\\u0430\\u043a\\u0442\\u043e\\u0432 \\u0432 \\u043c\\u0435\\u0441\\u044f\\u0446.\u0022,\u0022price\u0022:7900,\u0022specialPrice\u0022:null,\u0022fiscalInfo\u0022:{\u0022taxSystem\u0022:null,\u0022vatSystem\u0022:null},\u0022quantity\u0022:1,\u0022photo\u0022:\u0022advanced.jpg\u0022,\u0022photoList\u0022:[\u0022advanced.jpg\u0022]},\u0022limitsDescription\u0022:\u0022\\u0414\\u0430\\u043d\\u043d\\u044b\\u0439 \\u0442\\u0430\\u0440\\u0438\\u0444 \\u043f\\u043e\\u0437\\u0432\\u043e\\u043b\\u044f\\u0435\\u0442 \\u043e\\u0431\\u0440\\u0430\\u0431\\u0430\\u0442\\u044b\\u0432\\u0430\\u0442\\u044c \\u0434\\u043e 3000 \\u043a\\u043e\\u043d\\u0442\\u0430\\u043a\\u0442\\u043e\\u0432 \\u0432 \\u043c\\u0435\\u0441\\u044f\\u0446.\u0022,\u0022ecommerce\u0022:true,\u0022modules\u0022:[\u0022tariff.modules.ecommerce\u0022],\u0022__initializer__\u0022:null,\u0022__cloner__\u0022:null,\u0022__isInitialized__\u0022:true}]"

(in the db I have Cyrillic symbols). Have can I fix it?

My config.yml:

#FOSRestBundle
fos_rest:
    body_listener: true
    view:
      view_response_listener: force
    mime_types:
      json: ['application/json; charset=UTF-8', 'application/json']
    serializer:
      serialize_null: true
    body_converter:
      enabled: true
    format_listener:
      rules:
        - { path: '^/api',  priorities: ['json'], fallback_format: json, prefer_extension: true }
        - { path: '^/', priorities: [ 'html', '*/*'], fallback_format: html, prefer_extension: true }

Answer 1

JsonResponse will serialize your array, but it's already serialized by Serializer . You are now serializing your already serialized object.

Use setJson() instead:

$response = new JsonResponse();
$response->setJson($serializer->serialize($tariff, 'json'));

Take a look at \\Symfony\\Component\\HttpFoundation\\JsonResponse to what it's doing. Then you'll see that setting Content-Type is already done by JsonResponse::update (called from JsonResponse::setJson ).

If you use JsonResponse($data) or JsonResponse::setData() , \\json_encode is being called.
