…то, поскольку у `description` есть значение по умолчанию, даже если вы **ничего не вернёте** для этого поля, оно всё равно будет иметь это **значение по умолчанию**.

### Модель для данных ответа { #model-for-output-response-data }

Если поработать с интерактивной документацией и посмотреть ответ, то, хотя код ничего не добавил в одно из полей `description`, JSON‑ответ содержит значение по умолчанию (`null`):

`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 operations 関数* 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。

## 警告

* The frontend (running in the user's browser) sends that `username` and `password` to a specific URL in our API (declared with `tokenUrl="token"`).
* The API checks that `username` and `password`, and responds with a "token" (we haven't implemented any of this yet).
    * A "token" is just a string with some content that we can use later to verify this user.
    * Normally, a token is set to expire after some time.
