/// tip | Consejo

Puedes sobreescribir una dependencia utilizada en cualquier lugar de tu aplicación **FastAPI**.

La dependencia original podría ser utilizada en una *path operation function*, un *path operation decorator* (cuando no usas el valor de retorno), una llamada a `.include_router()`, etc.

FastAPI todavía podrá sobrescribirla.

Webargs est un outil qui a été créé pour fournir cela par-dessus plusieurs frameworks, dont Flask.

Il utilise Marshmallow pour effectuer la validation des données. Et il a été créé par les mêmes développeurs.

C'est un outil formidable et je l'ai beaucoup utilisé aussi, avant d'avoir **FastAPI**.

Como você viu em [Subaplicações - Montagens](sub-applications.md) e [Atrás de um Proxy](behind-a-proxy.md), 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 `WSGIMiddleware` { #using-wsgimiddleware }
