如何根据Laravel中的另一个切换显示最小和最大值

use App\Models\User;

public function getMinMaxValues()
{
    $minAge = User::min('age');
    $maxAge = User::max('age');

    return response()->json([
        'minAge' => $minAge,
        'maxAge' => $maxAge,
    ]);
}

Route::get('/min-max-values', [UserController::class, 'getMinMaxValues']);

public function getMinMaxValues($showMin)
{
    $minAge = User::min('age');
    $maxAge = User::max('age');

    if ($showMin) {
        return response()->json([
            'age' => $minAge,
        ]);
    } else {
        return response()->json([
            'age' => $maxAge,
        ]);
    }
}

Route::get('/min-max-values/{showMin}', [UserController::class, 'getMinMaxValues']);
