These examples are intentionally simple, but show how it all works.

In the chapters about security, there are utility functions that are implemented in this same way.

If you understood all this, you already know how those utility tools for security work underneath.

Como você viu em [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank} e [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank}, você pode **"montar"** aplicações WSGI.

Para isso, você pode utilizar o `WSGIMiddleware` para encapsular a sua aplicação WSGI, como por exemplo Flask, Django, etc.

## Usando o `WSGIMiddleware`

Você precisa importar o `WSGIMiddleware`.

    * **Concis** : Minimise la duplication de code. Plusieurs fonctionnalités à chaque déclaration de paramètre.
    * **Robuste** : Obtenez du code prêt pour être utilisé en production. Avec de la documentation automatique interactive.

Cuando uno de estos esquemas de seguridad usa OAuth2, también puedes declarar y usar scopes.

Cada "scope" es solo un string (sin espacios).

Normalmente se utilizan para declarar permisos de seguridad específicos, por ejemplo:

* `users:read` o `users:write` son ejemplos comunes.
* `instagram_basic` es usado por Facebook / Instagram.

Ensuite, en arrière-plan, il mettra ces données JSON-compatible (par exemple un `dict`) à l'intérieur d'un `JSONResponse` qui sera utilisé pour envoyer la réponse au client.

Mais vous pouvez retourner une `JSONResponse` directement à partir de vos *opérations de chemin*.

Cela peut être utile, par exemple, pour retourner des en-têtes personnalisés ou des cookies.
