Les documents de l’API utilisent **Swagger UI** et **ReDoc**, et chacune nécessite des fichiers JavaScript et CSS.

Par défaut, ces fichiers sont servis depuis un <abbr title="Content Delivery Network - Réseau de diffusion de contenu: Un service, normalement composé de plusieurs serveurs, qui fournit des fichiers statiques, comme JavaScript et CSS. Il est couramment utilisé pour servir ces fichiers depuis le serveur le plus proche du client, améliorant la performance.">CDN</abbr>.

# Envoyer des fichiers { #request-files }

Vous pouvez définir des fichiers à téléverser par le client en utilisant `File`.

/// info

Pour recevoir des fichiers téléversés, installez d'abord [`python-multipart`](https://github.com/Kludex/python-multipart).

Assurez-vous de créer un [environnement virtuel](../virtual-environments.md), de l'activer, puis d'installer le paquet, par exemple :

```console
$ pip install python-multipart
```
