## Response Status Code

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

You can pass directly the `int` code, like `404`.

But if you don't remember what each number code is for, you can use the shortcut constants in `status`:

OpenAPI tem uma forma para definir múltiplos “esquemas” de segurança.

Por usá-los, você pode ter vantagens de todas essas ferramentas baseadas nos padrões, incluindo os sistemas de documentação interativa.

OpenAPI define os seguintes esquemas de segurança:

* `apiKey`: uma chave específica de aplicação que pode vir de:
    * Um parâmetro query.
    * Um header.
    * Um cookie.

 *       duplicate entries; that is, while a key may appear twice in a {@code SetMultimap}, each
 *       must map to a different value. {@code SetMultimap} takes its name from the fact that the
 *       {@linkplain SetMultimap#get collection of values} associated with a given key fulfills the
 *       {@link java.util.Set} contract.

## 数値の検証: 浮動小数点、 大なり小なり

数値のバリデーションは`float`の値に対しても有効です。

ここで重要になってくるのは<abbr title="より大きい"><code>gt</code></abbr>だけでなく<abbr title="以下"><code>ge</code></abbr>も宣言できることです。これと同様に、例えば、値が`1`より小さくても`0`より大きくなければならないことを要求することができます。

したがって、`0.5`は有効な値ですが、`0.0`や`0`はそうではありません。

これは<abbr title="未満"><code>lt</code></abbr>も同じです。
