Laravel雄辩- pluck()角色名

Question

我正在尝试从带有角色的请求中获取经过身份验证的用户对象。我用的是斯帕蒂拉拉-权限和Laravel 8。

从请求中获取用户对象，如下

$request->user()->getRoleNames()->pluck('name');
return $request->user();

返回

{
   "id":1,
   "name":"User name",
   "email":"User email",
   "email_verified_at":null,
   "company":"--",
   "phone":"--",
   "created_at":"--",
   "updated_at":"--",
   "roles":[
      {
         "id":1,
         "name":"Super Admin",
         "guard_name":"web",
         "created_at":"--",
         "updated_at":"--",
         "pivot":{
            "model_id":1,
            "role_id":1,
            "model_type":"App\\Models\\User"
         }
      }
   ]
}

我需要归还的东西

{
   "id":1,
   "name":"User name",
   "email":"User email",
   "email_verified_at":null,
   "company":"--",
   "phone":"--",
   "created_at":"--",
   "updated_at":"--",
   "roles":["Super Admin"]
}

Answer 1

另一种选择是使用hidden、appends和访问器，比如getRoleNamesAttribute()。

class User extends Model {
  ...

  // This will hide `roles` from your `User`, when converted to JSON/Array/etc
  protected $hidden = ['roles'];

  // This will add `role_names` to your `User`, when converted to JSON/Array/etc
  protected $appends = ['role_names'];

  // Accessible via `$user->role_names`, or `user.role_names` in JSON
  public function getRoleNamesAttribute() {
    return $this->roles->pluck('name'); 
  }

  ... // Everything else
}

这样做，与return $request->user();一起将自动使roles不可见，并附加role_names。在您的代码中，您应该得到输出：

{
   "id":1,
   "name":"User name",
   "email":"User email",
   "email_verified_at":null,
   "company":"--",
   "phone":"--",
   "created_at":"--",
   "updated_at":"--",
   "role_names":["Super Admin"]
}

Answer 2

将roles添加到用户对象中，如下所示

$user = $request->user();
$user->roles = $user->roles()->pluck('name');
return $user;

Answer 3

您也可以这样做：

$user->roles = User::find($user->id)->getRoleNames();
