我正在使用 FOSRest 和 Willdurand/Hateoas 捆绑包。我遵循 https://github.com/willdurand/Hateoas#configuring-links中的示例
但 JSON 响应中没有“链接”字段。

主要是我想显示一个到角色实体的链接，但也许更容易找出导致SELF链接问题的原因，然后再走得更远。
这里是配置
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: 'AppBundle\Controller\ExceptionController::showAction'
serializer:
groups: ['Default']
sensio_framework_extra:
view:
annotations: true
request:
converters: true
这个配置很好，意味着所有端点都可以正常工作，除了没有链接。
此时，我在GET请求上得到了这个响应
[
{
"id": 1,
"name": "Test name",
"email": "test@email.com",
"username": "toskadv",
"active": true
},
{
"id": 2,
"name": "Test name",
"email": "test@email.com",
"username": "toskadv",
"active": true
},
{
"id": 3,
"name": "Test name",
"email": "test@email.com",
"username": "toskadv",
"active": true,
"roles": {
"id": 1,
"name": "ROLE_USER"
}
}
]
还有控制器数据。

* @package AppBundle\Controller

/**

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

$user->setRoles($role);
$em->persist($user);
$em->flush();
return $user;
}
