/// tip

Ce n'est probablement pas aussi important ou nécessaire si vous utilisez `Annotated`.

///

Disons que vous voulez déclarer le paramètre de requête `q` comme un `str` requis.

Et vous n'avez pas besoin de déclarer autre chose pour ce paramètre, donc vous n'avez pas vraiment besoin d'utiliser `Query`.

/// tip | Dica

Isso provavelmente não é tão importante ou necessário se você usar `Annotated`.

///

Vamos supor que você queira declarar o parâmetro de consulta `q` como uma `str` obrigatória.

E você não precisa declarar mais nada para esse parâmetro, então você realmente não precisa usar `Query`.

The main `Response` class, all the other responses inherit from it.

You can return it directly.

* `status_code` - An `int` HTTP status code.
* `headers` - A `dict` of strings.
* `media_type` - A `str` giving the media type. E.g. `"text/html"`.
