このソリューションは完全に機能しており、クラス JsonResponse() やオブジェクトを JMS シリアライザー バンドルとしてシリアル化するのに適した優れたバンドルの使用など、高速化するための多くの代替方法を時間とともに学習します。

しかし、火に肉を入れすぎないでください。

お役に立てば幸いです！

編集：

$entity-getPrice()の代わりにタイプミスしました$entity->getPrice()。

ajax 呼び出しのタイプは POST でなければなりません。

まだ入力していない場合は、コントローラーの先頭に次の行を忘れずに入力してください。

use Symfony\Component\HttpFoundation\Response;

今では完全に機能します。
