Essa mesma técnica se aplica para `Query`, `Cookie`, e `Header`. 😎

## Cookies com Modelos Pydantic

Declare o parâmetro de **cookie** que você precisa em um **modelo Pydantic**, e depois declare o parâmetro como um `Cookie`:

/// tip | "Dica"

Tenha em mente que cabeçalhos proprietários personalizados podem ser adicionados <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">usando o prefixo 'X-'</a>.

Pero puedes devolver una `JSONResponse` directamente de tu *operación de path*.

Esto puede ser útil, por ejemplo, para devolver cookies o headers personalizados.

## Devolver una `Response`

De hecho, puedes devolver cualquier `Response` o cualquier subclase de la misma.

/// tip | Consejo

`JSONResponse` en sí misma es una subclase de `Response`.
