Laravel 中的 setVisible 和 setHidden 模型方法

你可以使用 hidden 属性来指定哪些属性在模型转为 JSON 时隐藏：

namespace App\Models;
 
use Illuminate\Database\Eloquent\Model;
 
class User extends Model
{
    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = ['api_token'];
}

当你把模型转换为 array 或 json 时，将会隐藏 api_token 属性：

$user = User::find(1);

return $user->toArray();
/*
[
    "id" => 1,
    "name" => "Amit Merchant",
    "email" => "example@example.com",
]
*/

如果向动态的显示或隐藏某（几）个属性，请看下面的两个方法：

setVisible 方法

$user = User::find(1);

return $user->setVisible(['name', 'email'])->toArray();

/*
[
    "name" => "Amit Merchant",
    "email" => "
]
*/

setHidden 方法

$user = User::find(1);

return $user->setHidden(['api_token'])->toArray();
/*
[
    "id" => 1,
    "name" => "Amit Merchant",
    "email" => "example@example.com",
]
*/
