   * We use large numbers to avoid the integer cache. Normally, we'd accomplish that merely by using
   * `new Integer` (as we do) instead of `Integer.valueOf`. However, under J2KT, `new Integer`
   * gets translated back to `Integer.valueOf` because that is the only thing J2KT can support. And

OAuth2 a été conçu pour que le backend ou l'API puisse être indépendant du serveur qui authentifie l'utilisateur.

Mais dans ce cas, la même application **FastAPI** gérera l'API et l'authentification.

Voyons cela selon ce point de vue simplifié :

- L'utilisateur saisit le `username` et le `password` dans le frontend, puis appuie sur Entrée.

Eğer `Authorization` header’ını görmezse ya da değer `Bearer ` token’ı içermiyorsa, doğrudan 401 status code hatasıyla (`UNAUTHORIZED`) response döner.

Token’ın var olup olmadığını kontrol edip ayrıca hata döndürmenize bile gerek yoktur. Fonksiyonunuz çalışıyorsa, token içinde bir `str` olacağından emin olabilirsiniz.
