### **FastAPI** normal

Primero, escribe toda tu aplicación **FastAPI** como normalmente:

{* ../../docs_src/extending_openapi/tutorial001.py hl[1,4,7:9] *}

# Cuerpo - Múltiples Parámetros

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

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

Y también puedes declarar parámetros del cuerpo como opcionales, estableciendo el valor predeterminado a `None`:
