これは **Pydantic** によって引き続きサポートされています。Pydantic には [`dataclasses` の内部サポート](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel) があるためです。

そのため、上記のように明示的に Pydantic を使っていないコードでも、FastAPI は標準の dataclass を Pydantic 独自の dataclass に変換するために Pydantic を使用しています。

そして当然ながら、次の点も同様にサポートされます:

		if getRequestAuthType(r) == authTypeAnonymous {
			// As per "Permission" section in
			// https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectGET.html
			// If the object you request does not exist,
			// the error Amazon S3 returns depends on
			// whether you also have the s3:ListBucket
			// permission.

    - cron: '45 9 * * 0'
  push:
    branches: [ "master" ]

# Declare default permissions as read only.
permissions: read-all

jobs:
  analysis:
    name: Scorecard analysis
    runs-on: ubuntu-latest
    permissions:
      # Needed to upload the results to code-scanning dashboard.
      security-events: write
      # Needed to publish results and get a badge (see publish_results below).
      id-token: write

즉, Python에서 환경 변수로부터 읽어온 어떤 값이든 `str`이 되며, 다른 타입으로의 변환이나 검증은 코드에서 수행해야 합니다.

## Pydantic `Settings` { #pydantic-settings }

다행히 Pydantic은 환경 변수에서 오는 이러한 설정을 처리할 수 있는 훌륭한 유틸리티를 [Pydantic: Settings 관리](https://docs.pydantic.dev/latest/concepts/pydantic_settings/)로 제공합니다.

### `pydantic-settings` 설치하기 { #install-pydantic-settings }

먼저 [가상 환경](../virtual-environments.md)을 만들고 활성화한 다음, `pydantic-settings` 패키지를 설치하세요:

<div class="termy">

這表示在 Python 中自環境變數讀取到的任何值都會是 `str`，而任何轉型成其他型別或驗證都必須在程式碼中完成。

## Pydantic `Settings` { #pydantic-settings }

幸好，Pydantic 提供了很好的工具，可用來處理由環境變數而來的設定：[Pydantic：設定管理](https://docs.pydantic.dev/latest/concepts/pydantic_settings/)。

### 安裝 `pydantic-settings` { #install-pydantic-settings }

首先，請先建立你的[虛擬環境](../virtual-environments.md)，啟用它，然後安裝 `pydantic-settings` 套件：

<div class="termy">

```console

		if versionID == "" {
			versionID = mustGetUUID()
			fi.IsLatest = true // we are creating a new version so this is latest.
		}
	}

	modTime = UTCNow() // We only preserve modTime if dstOpts.MTime is true.
	// in all other cases mtime is latest.

	fi.VersionID = versionID // set any new versionID we might have created
	fi.ModTime = modTime     // set modTime for the new versionID

    }

    @Test
    public void test_escapeLDAPSearchFilter_withMixedContent() {
        LdapManager ldapManager = new LdapManager();
        ldapManager.init();

        // Mixed normal and special characters
        assertEquals("user\\28test\\29", ldapManager.escapeLDAPSearchFilter("user(test)"));
