Mais si vous avez besoin d'accéder aux variables et objets de la même application **FastAPI**, ou si vous avez besoin d'effectuer de petites tâches d'arrière-plan (comme envoyer des notifications par email), vous pouvez simplement vous contenter d'utiliser `BackgroundTasks`.

## Résumé

///

**FastAPI** effectue la conversion de la requête de façon transparente, de sorte que les objets `item` et `user` se trouvent correctement définis.

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).

 *  Work around the Alcatel `getByInetAddress` bug (thanks k.kocel)
 *  Be more aggressive about testing pooled sockets before reuse. (thanks
    warpspin)
 *  Include `Content-Type` and `Content-Encoding` in the Apache HTTP client
    adapter. (thanks kwuollett)
 *  Add a media type class to OkHttp.
 *  Change custom header prefix:
