我想使用symfony php框架创建自己的Restful API。 当然，我用 - FOSRestBundle - FOSUserBundle - LexikJWTAuthenticationBundle - JMSSerializerBundle
配置完所有捆绑包后，我的API返回空对象。
[{}{}{}{}{}{}{}]
在我的控制器中我写
class ChantController extends Controller
{
public function indexAction()
{
$em = $this->getDoctrine()->getManager();
$chants = $em->getRepository(Chant::class)->findAll();
return new JsonResponse($chants);
}
}
由LexikJWTAuthenticationBundle创建的登录api可以正常工作，但是我自己的路由不起作用。 这是我的配置文件

请帮忙吗？
已更新
我为此更改了代码：
public function indexAction()
{
$em = $this->getDoctrine()->getManager();
$chants = $em->getRepository(Chant::class)->findAll();
$data = $this->get('jms_serializer')->serialize($chants, 'json', SerializationContext::create()->setGroups(array('list')));
$response = new Response($data);
$response->headers->set('Content-Type', 'application/json');
return $response;
}
答案 0 :(得分：0)
要做的事情：
您的类应扩展FOSRestController以使用REST功能。
class ChantController extends FOSRestController
您可以像这样序列化并返回响应：
public function listAction(ParamFetcherInterface $paramFetcher, Request $request)
{
//...your code...//
$yourObjectifiedResult = $getRepository('yourentity')->findBy(['var' => $var]);
$yourNormalizedResult = $this->normalizeWithCircularHandler(
$yourObjectifiedResult,
['groups']);
//Serializer will convert your result from Object to Json Array automatically. To get a specific set of data, you can use groups.
$response = new JsonResponse(['success' => true, 'data' => $yourNormalizedResult ]);
$response->setStatusCode(Response::HTTP_OK);
return $response;
}
public function normalizeWithCircularHandler($data, $displayGroups, $normalizerCallbacks = false)
{
$encoder = new JsonEncoder();
$classMetadataFactory = new ClassMetadataFactory(new AnnotationLoader(new AnnotationReader()));
$normalizer = new ObjectNormalizer($classMetadataFactory);
$normalizer->setCircularReferenceHandler(function ($object) {
return $object->getId();
});
if(false != $normalizerCallbacks && is_array($normalizerCallbacks)) {
$normalizer->setCallbacks($normalizerCallbacks);
}
$serializer = new Serializer([$normalizer], [$encoder]);
return $serializer->normalize($data , null, ['groups' => $displayGroups]);
}
