FastAPI에서 `BackgroundTask`를 단독으로 사용하는 것은 여전히 가능합니다. 하지만 객체를 코드에서 생성하고, 이 객체를 포함하는 Starlette `Response`를 반환해야 합니다.

<a href="https://www.starlette.io/background/" class="external-link" target="_blank">`Starlette의 공식 문서`</a>에서 백그라운드 작업에 대한 자세한 내용을 확인할 수 있습니다.

## 경고

만약 무거운 백그라운드 작업을 수행해야하고 동일한 프로세스에서 실행할 필요가 없는 경우 (예: 메모리, 변수 등을 공유할 필요가 없음) <a href="https://docs.celeryq.dev" class="external-link" target="_blank">`Celery`</a>와 같은 큰 도구를 사용하면 도움이 될 수 있습니다.

If you want to play with JWT tokens and see how they work, check <a href="https://jwt.io/" class="external-link" target="_blank">https://jwt.io</a>.

## Install `PyJWT` { #install-pyjwt }

We need to install `PyJWT` to generate and verify the JWT tokens in Python.

В этом и заключается преимущество стандартов...

If a client tries to send some **extra** data in the **query parameters**, they will receive an **error** response.

For example, if the client tries to send a `tool` query parameter with a value of `plumbus`, like:

```http
https://example.com/items/?limit=10&tool=plumbus
```

They will receive an **error** response telling them that the query parameter `tool` is not allowed:

```json

    "detail": [
