**FastAPI** s'assure de lire ces données au bon endroit au lieu de JSON.

/// note | Détails techniques

Les données issues des formulaires sont normalement encodées avec le « type de média » `application/x-www-form-urlencoded`.

Mais lorsque le formulaire inclut des fichiers, il est encodé en `multipart/form-data`. Vous lirez la gestion des fichiers dans le chapitre suivant.

But for the login *path operation*, we need to use these names to be compatible with the spec (and be able to, for example, use the integrated API documentation system).

The spec also states that the `username` and `password` must be sent as form data (so, no JSON here).

### `scope` { #scope }

The spec also says that the client can send another form field "`scope`".

    * nombres (`int`, `float`) avec valeurs minimale et maximale, etc.

* Validation pour des types plus exotiques, comme :
    * URL.
    * Email.
    * UUID.
    * ... et autres.

Toutes les validations sont gérées par le **Pydantic** bien établi et robuste.
