В опросе Python-разработчиков было выяснено, <a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">что наиболее часто используемой функцией редакторов, является "автодополнение"</a>.

이 예제에서는 응답이 반환된 후에 `log.txt` 파일에 메시지가 기록됩니다.

요청에 쿼리가 있는 경우 백그라운드 작업의 로그에 기록됩니다.

그리고 _경로 작동 함수_ 에서 생성된 또 다른 백그라운드 작업은 경로 매개 변수를 활용하여 사용하여 메시지를 작성합니다.

## 기술적 세부사항

`BackgroundTasks` 클래스는 <a href="https://www.starlette.io/background/" class="external-link" target="_blank">`starlette.background`</a>에서 직접 가져옵니다.

Aber Sie bekommen die gleiche Editor-Unterstützung in <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> und in den meisten anderen Python-Editoren:

그래서 **FastAPI**의 코드를 작성하기 전에 몇 달 동안 OpenAPI, JSON Schema, OAuth2 명세를 연구하며 이들의 관계와 겹치는 부분, 차이점을 이해했습니다.

## 디자인

그 후, **FastAPI** 사용자가 될 개발자로서 사용하고 싶은 개발자 "API"를 디자인했습니다.

[Python Developer Survey](https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools)에 따르면 약 80%의 Python 개발자가 PyCharm, VS Code, Jedi 기반 편집기 등에서 개발합니다. 이 과정에서 여러 아이디어를 테스트했습니다.

대부분의 다른 편집기도 유사하게 동작하기 때문에, **FastAPI**의 이점은 거의 모든 편집기에서 누릴 수 있습니다.
