Si vous ne voulez pas leur donner de valeur par défaut mais juste les rendre optionnels, utilisez `None` comme valeur par défaut.

Mais si vous voulez rendre un paramètre de requête obligatoire, vous pouvez juste ne pas y affecter de valeur par défaut :

* TCP ne connaît pas les "domaines", seulement les adresses IP.
    * L'information sur le domaine spécifique demandé se trouve dans les données HTTP.
* Les certificats HTTPS "certifient" un certain domaine, mais le protocole et le cryptage se font au niveau TCP, avant de savoir quel domaine est traité.
* Par défaut, cela signifie que vous ne pouvez avoir qu'un seul certificat HTTPS par adresse IP.

# Deployment (Yayınlama)

**FastAPI** uygulamasını deploy etmek oldukça kolaydır.

## Deployment Ne Anlama Gelir?

Bir uygulamayı **deploy** etmek (yayınlamak), uygulamayı **kullanıcılara erişilebilir hale getirmek** için gerekli adımları gerçekleştirmek anlamına gelir.
