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.

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.
