## Caso de uso

Por ejemplo, imagina que quieres devolver un código de estado HTTP de "OK" `200` por defecto.

Pero si los datos no existieran, quieres crearlos y devolver un código de estado HTTP de "CREATED" `201`.

Pero todavía quieres poder filtrar y convertir los datos que devuelves con un `response_model`.

Para esos casos, puedes usar un parámetro `Response`.

## Usa un parámetro `Response`

 * is returned by upstream, or after the upstream source has been exhausted.
 *
 * As bytes are returned from upstream they are written to a local file. Downstream sources read
 * from this file as necessary.
 *
 * This class also keeps a small buffer of bytes recently read from upstream. This is intended to
 * save a small amount of file I/O and data copying.
