Il effectue également la validation des données (même imbriquées les unes dans les autres), et permet de les documenter correctement (schéma OpenAPI et documentation auto-générée).

## Valeurs scalaires dans le body

De la même façon qu'il existe `Query` et `Path` pour définir des données supplémentaires pour les paramètres query et path, **FastAPI** fournit un équivalent `Body`.

As it is discouraged, the interactive docs with Swagger UI won't show the documentation for the body when using `GET`, and proxies in the middle might not support it.

## Documents OpenAPI et API

Si vous renvoyez directement des codes HTTP et des réponses supplémentaires, ils ne seront pas inclus dans le schéma OpenAPI (la documentation de l'API), car FastAPI n'a aucun moyen de savoir à l'avance ce que vous allez renvoyer.

Das ermöglicht es Ihnen, ein feingranuliertes Berechtigungssystem nach dem OAuth2-Standard in Ihre OpenAPI-Anwendung (und deren API-Dokumentation) zu integrieren.
