This way you can make sure you're not wasting your time on something that isn't
  considered to be in Apache Maven's scope.
+ Submit a ticket for your issue, assuming one does not already exist.
  + Clearly describe the issue, including steps to reproduce when it is a bug.
  + Make sure you fill in the earliest version that you know has the issue.
+ Fork the repository on GitHub.

Nota que esto significa "`one_person` es una **instance** de la clase `Person`".

No significa "`one_person` es la **clase** llamada `Person`".

## Modelos Pydantic

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> es un paquete de Python para realizar la validación de datos.

Declaras la "forma" de los datos como clases con atributos.

Y cada atributo tiene un tipo.

To learn more about the `Request` check <a href="https://www.starlette.io/requests/" class="external-link" target="_blank">Starlette's docs about Requests</a>.

///

The only thing the function returned by `GzipRequest.get_route_handler` does differently is convert the `Request` to a `GzipRequest`.

### Revisa la documentación

Ahora puedes iniciar tu aplicación e ir a <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

Verás tu documentación incluyendo una sección de "Callbacks" para tu *path operation* que muestra cómo debería verse la *API externa*:

Por exemplo, para declarar um cabeçalho de `X-Token` que pode aparecer mais de uma vez, você pode escrever:

{* ../../docs_src/header_params/tutorial003_py310.py hl[7] *}

Se você se comunicar com essa *operação de caminho* enviando dois cabeçalhos HTTP como:

```
X-Token: foo
X-Token: bar
```

A resposta seria como:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Recapitulando

Puedes declarar un response que sea la `Union` de dos o más tipos, eso significa que el response sería cualquiera de ellos.

Se definirá en OpenAPI con `anyOf`.

Para hacerlo, usa el type hint estándar de Python <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

/// note | Nota

It will perform the validation of the compound data, and will document it like that for the OpenAPI schema and automatic docs.

## Singular values in body { #singular-values-in-body }

The same way there is a `Query` and `Path` to define extra data for query and path parameters, **FastAPI** provides an equivalent `Body`.

This release also stabilizes many APIs in the `mockwebserver3` artifact that's new in 5.0.

 *  Breaking: `RecordedRequest.body` is now nullable. Null is used when the request does not have a
    body.

 *  Breaking: `RecordedRequest.chunkSizes` is now nullable. Null is used when the request does not
    use chunked encoding. This is different from an empty list - that indicates the request is
    chunked but has no data.

	Isso é incrivelmente útil enquanto se desenvolve e debuga o código que interage com a sua API.

## Documentação

Quando você abrir o seu navegador em <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>, você verá de forma automática e interativa a documentação da API como:
