FastAPI CLI toma el path de tu programa Python (por ejemplo, `main.py`), detecta automáticamente la `FastAPI` instance (comúnmente llamada `app`), determina el proceso de import correcto, y luego la sirve.

Para producción usarías `fastapi run` en su lugar. 🚀

But when the form includes files, it is encoded as `multipart/form-data`. If you use `File`, **FastAPI** will know it has to get the files from the correct part of the body.

## Request body + path + parámetros de query

También puedes declarar parámetros de **body**, **path** y **query**, todos al mismo tiempo.

**FastAPI** reconocerá cada uno de ellos y tomará los datos del lugar correcto.

Los parámetros de la función se reconocerán de la siguiente manera:

You will see the automatic API docs, including the paths from all the submodules, using the correct paths (and prefixes) and the correct tags:
