php – Symfony和Wildurand / Hateoas Bundle – 没有关于JSON r

但JSON响应中没有“链接”字段.

/**

}

主要是我想显示一个链接到Roles实体,但也许更容易找出导致甚至SELF链接的问题,然后更进一步.

这是配置

fos_rest:
    routing_loader:
        default_format: json
        include_format: false
    view:
        view_response_listener: 'force'
    body_converter:
        enabled: true
        validate: true
        validation_errors_argument: validationErrors
    param_fetcher_listener: true
    exception:
        enabled: true
        exception_controller: 'AppBundleControllerExceptionController::showAction'
    serializer:
        groups: ['Default']

sensio_framework_extra:
    view:
        annotations: true
    request:
        converters: true

这个配置很好,意味着除了没有链接外,所有端点都能正常工作.

此时,我收到了GET请求的响应

[
  {
    "id": 1,"name": "Test name","email": "test@email.com","username": "toskadv","active": true
  },{
    "id": 2,{
    "id": 3,"active": true,"roles": {
      "id": 1,"name": "ROLE_USER"
    }
  }
]

还有控制器数据.

/**
 * Class UsersController
 * @package AppBundleController
 */
class UsersController extends AbstractController
{
    use ControllerTrait;

    /**
     * @RestView()
     */
    public function getUsersAction()
    {
        $users = $this->getDoctrine()->getRepository('AppBundle:User')->findAll();

        return $users;
    }

    /**

     *
     * @RestView(statusCode=201)

     *
     * @return User $user
     */
    public function postUsersAction(User $user,ConstraintViolationListInterface $validationErrors)
    {
        if (count($validationErrors) > 0) {
            throw new ValidationException($validationErrors);
        }
        $em = $this->getDoctrine()->getManager();
        $role = $em->getRepository('AppBundle:Role')->find(1);
        $user->setRoles($role);

        $em->persist($user);
        $em->flush();

        return $user;
    }

    /**
     * @param User|null $user
     *
     * @RestView()
     */
    public function deleteUserAction(User $user = null) {
        if (null === $user) {
            return $this->view(null,404);
        }

        $em = $this->getDoctrine()->getManager();
        $em->remove($user);
        $em->flush();
    }


    /**

        return $role;
    }

     *
     * @RestView()

    public function getUserRolesAction(User $user)
    {
        return $user->getRoles();
    }

    public function postUserRolesAction(User $user,Role $role,ConstraintViolationListInterface $validationErrors)
    {
        if (count($validationErrors) > 0) {
         throw new ValidationException($validationErrors);
        }

        $role->setUser($user);

        $em = $this->getDoctrine()->getManager();
        $user->getRoles()->add($role);

        $em->persist($user);
        $em->flush();

        return $role;
    }
