しかし、`Request` オブジェクトに直接アクセスする必要がある場面もあります。

## `Request` オブジェクトの詳細 { #details-about-the-request-object }

**FastAPI** は内部的には **Starlette** の上にいくつかのツール層を載せたものなので、必要に応じて Starlette の [`Request`](https://www.starlette.dev/requests/) オブジェクトを直接使えます。

また、`Request` オブジェクトから直接データ（例: ボディ）を取得する場合、そのデータは FastAPI によって検証・変換・ドキュメント化（OpenAPI による自動 API ユーザーインターフェース向け）されません。

ただし、通常どおりに宣言された他のパラメータ（例: Pydantic モデルのボディ）は引き続き検証・変換・注釈付けなどが行われます。

## Технічні деталі { #technical-details }

Клас `BackgroundTasks` походить безпосередньо з [`starlette.background`](https://www.starlette.dev/background/).

Він імпортується/включається безпосередньо у FastAPI, щоб ви могли імпортувати його з `fastapi` і випадково не імпортували альтернативний `BackgroundTask` (без `s` в кінці) з `starlette.background`.
