「Facebook でログイン」「Google でログイン」「GitHub でログイン」「Microsoft でログイン」「X (Twitter) でログイン」するたびに、そのアプリケーションはスコープ付きの OAuth2 を使っています。

この節では、同じスコープ付き OAuth2 を使って、**FastAPI** アプリケーションで認証と認可を管理する方法を見ていきます。

/// warning | 注意

これはやや高度な内容です。はじめたばかりであれば読み飛ばしても構いません。

OAuth2 のスコープは必ずしも必要ではなく、認証と認可は好きなやり方で実装できます。

ただし、スコープ付きの OAuth2 は、API（OpenAPI）や API ドキュメントにきれいに統合できます。

とはいえ、これらのスコープやその他のセキュリティ／認可要件の適用は、必要に応じてコードの中で行う必要があります。

            validateStringNoExpression("groupId", problems, Severity.WARNING, Version.V20, m.getGroupId(), m);
            if (parent == null) {
                validateStringNotEmpty("groupId", problems, Severity.FATAL, Version.V20, m.getGroupId(), m);
            }

            validateStringNoExpression("artifactId", problems, Severity.WARNING, Version.V20, m.getArtifactId(), m);

    HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
    loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BASIC);
    client.networkInterceptors().add(loggingInterceptor);
    ```

    **Warning:** Avoid `Level.HEADERS` and `Level.BODY` in production because
    they could leak passwords and other authentication credentials to insecure
    logs.

完全符合我们的预期。✔️

这是因为 FastAPI 使用该 `root_path` 在 OpenAPI 中创建默认的 `server`，其 URL 来自 `root_path`。

## 附加的服务器 { #additional-servers }

/// warning | 警告

这是一个更高级的用例，可以跳过。

///

默认情况下，**FastAPI** 会在 OpenAPI 模式中使用 `root_path` 的 URL 创建一个 `server`。

但你也可以提供其他备选的 `servers`，例如你希望让“同一个”文档界面同时与预发布环境和生产环境交互。

## `Field`'ı import edin { #import-field }

/// warning | Uyarı

`Field`'ın, diğerlerinin (`Query`, `Path`, `Body` vb.) aksine `fastapi`'den değil doğrudan `pydantic`'den import edildiğine dikkat edin.
