## FastAPI의 기능

**FastAPI**는 다음과 같은 기능을 제공합니다:

### 개방형 표준을 기반으로

* <abbr title="엔드포인트, 라우트로도 알려져 있습니다">경로</abbr><abbr title="POST, GET, PUT, DELETE와 같은 HTTP 메소드로 알려져 있습니다">작동</abbr>, 매개변수, 본문 요청, 보안 그 외의 선언을 포함한 API 생성을 위한 <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank"><strong>OpenAPI</strong></a>

Sie können `response_model` in jeder möglichen *Pfadoperation* verwenden:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* usw.
