Ya creaste una API que:

* Recibe requests HTTP en los _paths_ `/` y `/items/{item_id}`.
* Ambos _paths_ toman _operaciones_ `GET` (también conocidas como métodos HTTP).
* El _path_ `/items/{item_id}` tiene un _parámetro de path_ `item_id` que debe ser un `int`.
* El _path_ `/items/{item_id}` tiene un _parámetro de query_ `q` opcional que es un `str`.

Una de esas variables es la variable `PATH`.

/// tip | Consejo

Puedes aprender más sobre la variable de entorno `PATH` en la sección [Variables de Entorno](environment-variables.md#path-environment-variable){.internal-link target=_blank}.

///

Activar un entorno virtual agrega su path `.venv/bin` (en Linux y macOS) o `.venv\Scripts` (en Windows) a la variable de entorno `PATH`.

# Body - Paramètres multiples

Maintenant que nous avons vu comment manipuler `Path` et `Query`, voyons comment faire pour le corps d'une requête, communément désigné par le terme anglais "body".

## Mélanger les paramètres `Path`, `Query` et body

Tout d'abord, sachez que vous pouvez mélanger les déclarations des paramètres `Path`, `Query` et body, **FastAPI** saura quoi faire.

    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)
