백그라운드 작업으로 실행할 함수를 정의합니다.

이것은 단순히 매개변수를 받을 수 있는 표준 함수일 뿐입니다.

**FastAPI**는 이것이 `async def` 함수이든, 일반 `def` 함수이든 내부적으로 이를 올바르게 처리합니다.

이 경우, 아래 작업은 파일에 쓰는 함수입니다. (이메일 보내기 시물레이션)

그리고 이 작업은 `async`와 `await`를 사용하지 않으므로 일반 `def` 함수로 선언합니다.

## 백그라운드 작업 추가

_경로 작동 함수_ 내에서 작업 함수를 `.add_task()` 함수 통해 _백그라운드 작업_ 개체에 전달합니다.

* <a href="https://jinja.palletsprojects.com" target="_blank"><code>jinja2</code></a> - Required if you want to use the default template configuration.

def read_item(item_id: int, q: Union[str, None] = None):

<summary>또는 <code>async def</code> 사용하기...</summary>

여러분의 코드가 `async` / `await`을 사용한다면, `async def`를 사용하십시오.

If you select "Watching" instead of "Releases only" you will receive notifications when someone creates a new issue or question. You can also specify that you only want to be notified about new issues, or discussions, or PRs, etc.

Then you can try and help them solve those questions.

        Artifact managedOriginatingArtifact = versionMap.get(originatingArtifact.getDependencyConflictId());

        if (managedOriginatingArtifact != null) {
            // TODO we probably want to warn the user that he is building an artifact with
            // different values than in dependencyManagement
            if (managedVersions instanceof ManagedVersionMap) {

These examples run the server program (e.g Uvicorn), starting **a single process**, listening on all the IPs (`0.0.0.0`) on a predefined port (e.g. `80`).

This is the basic idea. But you will probably want to take care of some additional things, like:

* Security - HTTPS
* Running on startup
* Restarts
* Replication (the number of processes running)
* Memory
* Previous steps before starting

Ces dernières, lorsqu'elles sont appelées, renvoient des instances de classes du même nom.
