返回 api 资源时出现问题。我正在使用Spatie Laravel 权限。

碰巧在我的特殊情况下，我试图返回一个包含用户详细信息的 api 资源，以及用户拥有的角色和权限。

我的UserResorce.php

class UserResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param Request $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'roles' => RoleResource::collection($this->whenLoaded('roles')),
            'permissions' => PermissionResource::collection($this->whenLoaded('permissions')),
        ];
    }
}

我的RoleResource.php

class RoleResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param Request $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'permissions' => PermissionResource::collection($this->whenLoaded('permissions'))
        ];
    }
}

我的PermissionResource.php

class PermissionResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param Request $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name
        ];
    }
}

正如您在文件中看到的那样，我只在真正需要它们UserResource.php时才加载rolesand 。permissions这样，如果我执行以下操作：

class UserController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        return UserResource::make(User::find(1));
    }

我得到以下结果：

{
  "data": {
    "id":1,
    "name":"User Name 1",
    "email":"admin@example.com",
  }
}

因此，要加载相同的结果，但这次使用与用户关联的角色，我执行以下操作：

class UserController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        return UserResource::make(User::with(['roles'])->find(1));
    }

正如预期的那样，我得到以下结果：

{
  "data": {
    "id":1,
    "name":"User Name 1",
    "email":"admin@example.com",
    "roles": {
      0: {
        "id": 1,
        "name": "Administrator",
      }
    }
  }
}

现在我的问题如下，为了获取用户角色和权限，我执行了以下操作：

class UserController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        return UserResource::make(User::with(['roles', 'permissions'])->find(1));
    }

但是我在键中得到了一个空对象"permissions"，所以我更仔细地分析了，是用户拥有的权限是由他们定义的role，我查看了文档，我看到我可以使用getAllPermissions()方法获得用户的所有权限。所以我做了以下事情：

class UserResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param Request $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'roles' => RoleResource::collection($this->whenLoaded('roles')),
            'permissions' => PermissionResource::collection($this->whenLoaded('permissions', function () {
                return $this->getAllPermissions();
            })),
        ];
    }
}

但是通过这种方式，它也加载了permissions角色关系，它会得到一个意想不到的结果，如下所示：

{
  "data": {
    "id":1,
    "name":"User Name 1",
    "email":"admin@example.com",
    "roles": {
      0: {
        "id": 1,
        "name": "Administrator",
        "permissions": {
          0: {
            "id": 1
            "name": "Create Users"
          }
        }
      }
    },
    "permissions": {
      0: {
        "id": 1,
        "name": "Create Users",
     }
  }
}

这不是预期的结果，因为我在执行时期望的结果：

return UserResource::make(User::with(['roles', 'permissions'])->find(1));

应通过以下方式：

{
  "data": {
    "id":1,
    "name":"User Name 1",
    "email":"admin@example.com",
    "roles": {
      0: {
        "id": 1,
        "name": "Administrator",
      }
    },
   "permissions": {
      0: {
        "id": 1,
        "name": "Create Users",
     }
  }
}

并在执行时：

return UserResource::make(User::with(['roles.permissions', 'permissions'])->find(1));

我期待以下结果：

{
  "data": {
    "id":1,
    "name":"User Name 1",
    "email":"admin@example.com",
    "roles": {
      0: {
        "id": 1,
        "name": "Administrator",
        "permissions": {
          0: {
            "id": 1
            "name": "Create Users"
          }
        }
      }
    },
    "permissions": {
      0: {
        "id": 1,
        "name": "Create Users",
     }
  }
}

有人可以帮我解决这个问题吗？非常感谢您提前。
