### 대안 API 문서

그리고 이제, <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>로 가봅니다.

대안 자동 문서를 볼 수 있습니다 (<a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a> 제공):

/// check | 확인

즉, 파이썬 타입 선언을 하면 **FastAPI**는 데이터 검증을 합니다.

오류에는 정확히 어느 지점에서 검증을 통과하지 못했는지 명시됩니다.

이는 API와 상호 작용하는 코드를 개발하고 디버깅하는 데 매우 유용합니다.

## 문서화

그리고 브라우저에서 <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>를 열면, 다음과 같이 자동 대화식 API 문서를 볼 수 있습니다:

例如，您可以创建一个名为 `config.py` 的文件，其中包含以下内容：

{* ../../docs_src/settings/app01/config.py *}

然后在一个名为 `main.py` 的文件中使用它：

{* ../../docs_src/settings/app01/main.py hl[3,11:13] *}

/// tip

您还需要一个名为 `__init__.py` 的文件，就像您在[Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}中看到的那样。

///

## 在依赖项中使用设置

For example:

* <a href="https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment" class="external-link" target="_blank">VS Code</a>
* <a href="https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html" class="external-link" target="_blank">PyCharm</a>

/// tip

You normally have to do this only **once**, when you create the virtual environment.

///

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

Das ist dank **Pydantic** ebenfalls möglich, da es <a href="https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel" class="external-link" target="_blank">`dataclasses` intern unterstützt</a>.

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

This is still supported thanks to **Pydantic**, as it has <a href="https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel" class="external-link" target="_blank">internal support for `dataclasses`</a>.

	return "Destination bucket does not exist: " + e.Bucket
}

// BucketRemoteTargetNotFound remote target does not exist.
type BucketRemoteTargetNotFound GenericError

func (e BucketRemoteTargetNotFound) Error() string {
	return "Remote target not found: " + e.Bucket
}

// RemoteTargetConnectionErr remote target connection failure.
type RemoteTargetConnectionErr struct {
	Err       error
	Bucket    string

```

停止した場合に自動的に再起動させるツールを設定したいかもしれません。

さらに、<a href="https://gunicorn.org/" class="external-link" target="_blank">Gunicorn</a>をインストールして<a href="https://www.uvicorn.dev/#running-with-gunicorn" class="external-link" target="_blank">Uvicornのマネージャーとして使用したり</a>、複数のワーカーでHypercornを使用したいかもしれません。

ワーカー数などの微調整も行いたいかもしれません。
