これは、FastAPI に直接インポート/インクルードされるため、`fastapi` からインポートできる上に、`starlette.background`から別の `BackgroundTask` (末尾に `s` がない) を誤ってインポートすることを回避できます。

`BackgroundTasks`のみを使用することで (`BackgroundTask` ではなく)、`Request` オブジェクトを直接使用する場合と同様に、それを *path operation function* パラメーターとして使用し、**FastAPI** に残りの処理を任せることができます。

それでも、FastAPI で `BackgroundTask` を単独で使用することは可能ですが、コード内でオブジェクトを作成し、それを含むStarlette `Response` を返す必要があります。

Und wir können eine Liste von `dependencies` hinzufügen, die allen *Pfadoperationen* im Router hinzugefügt und für jeden an sie gerichteten <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> ausgeführt/aufgelöst werden.

### HTTPS 요청 { #https-request }

이제 클라이언트와 서버(구체적으로는 브라우저와 TLS Termination Proxy)가 **암호화된 TCP 연결**을 갖게 되었으니 **HTTP 통신**을 시작할 수 있습니다.

따라서 클라이언트는 **HTTPS 요청**을 보냅니다. 이는 암호화된 TLS 연결을 통해 전달되는 HTTP 요청일 뿐입니다.
