프로덕션 환경에서는 `fastapi run` 명령어를 사용합니다. 🚀

내부적으로, **FastAPI CLI**는 고성능의, 프로덕션에 적합한, ASGI 서버인 <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>을 사용합니다. 😎

## `fastapi dev`

`fastapi dev` 명령을 실행하면 개발 모드가 시작됩니다.

## `Annotated` im Typ des `q`-Parameters verwenden

Erinnern Sie sich, wie ich in [Einführung in Python-Typen](../python-types.md#typhinweise-mit-metadaten-annotationen){.internal-link target=_blank} sagte, dass Sie mittels `Annotated` Metadaten zu Ihren Parametern hinzufügen können?

import kotlin.annotation.AnnotationTarget.CLASS

`status_code`パラメータはHTTPステータスコードを含む数値を受け取ります。

/// info | 情報

`status_code`は代わりに、Pythonの<a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>のように、`IntEnum`を受け取ることもできます。

これは:

* レスポンスでステータスコードを返します。
* OpenAPIスキーマ（およびユーザーインターフェース）に以下のように文書化します:

# Response - Change Status Code { #response-change-status-code }

You probably read before that you can set a default [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank}.

But in some cases you need to return a different status code than the default.

## Use case { #use-case }

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

# Retorno - Altere o Código de Status

Você provavelmente leu anteriormente que você pode definir um [Código de Status do Retorno](../tutorial/response-status-code.md){.internal-link target=_blank} padrão.

Porém em alguns casos você precisa retornar um código de status diferente do padrão.

## Caso de uso

Por exemplo, imagine que você deseja retornar um código de status HTTP de "OK" `200` por padrão.
