 *  New: Publish a [bill of materials (BOM)][bom] for OkHttp. Depend on this from Gradle or Maven to
    keep all of your OkHttp artifacts on the same version, even if they're declared via transitive
    dependencies. You can even omit versions when declaring other OkHttp dependencies.

    ```kotlin
    dependencies {
       api(platform("com.squareup.okhttp3:okhttp-bom:4.4.0"))

If you need to upgrade a version or add a new package you would **do this again**.

///

### Install Packages Directly { #install-packages-directly }

If you're in a hurry and don't want to use a file to declare your project's package requirements, you can install them directly.

/// tip

It's a (very) good idea to put the packages and versions your program needs in a file (for example `requirements.txt` or `pyproject.toml`).

/// note | 참고

이 경우 FastAPI는 리스트의 내용을 검사하지 않음을 명심하세요.

예를 들어, `list[int]`는 리스트 내용이 정수인지 검사(및 문서화)합니다. 하지만 `list` 단독일 경우는 아닙니다.

簡単のため、ここでは受け取ったスコープをそのままトークンに追加しています。

しかし、本番アプリケーションではセキュリティのため、ユーザーが実際に持つことができるスコープ、または事前に定義したスコープだけを追加するようにしてください。

## path operation と依存関係でスコープを宣言 { #declare-scopes-in-path-operations-and-dependencies }

ここでは、`/users/me/items/` の path operation が `items` スコープを必要とするように宣言します。

そのために、`fastapi` から `Security` をインポートして使います。

/// note | 注意

请记住，在这种情况下 FastAPI 不会检查列表的内容。

例如，`list[int]` 会检查（并记录到文档）列表的内容必须是整数。但仅用 `list` 不会。
