Imaginemos que quieres obtener la dirección IP/host del cliente dentro de tu *path operation function*.

Para eso necesitas acceder al request directamente.

{* ../../docs_src/using_request_directly/tutorial001_py39.py hl[1,7:8] *}

Al declarar un parámetro de *path operation function* con el tipo siendo `Request`, **FastAPI** sabrá pasar el `Request` en ese parámetro.

# Cuerpo - Múltiples Parámetros { #body-multiple-parameters }

Ahora que hemos visto cómo usar `Path` y `Query`, veamos usos más avanzados de las declaraciones del request body.

## Mezclar `Path`, `Query` y parámetros del cuerpo { #mix-path-query-and-body-parameters }

Primero, por supuesto, puedes mezclar las declaraciones de parámetros de `Path`, `Query` y del request body libremente y **FastAPI** sabrá qué hacer.
