### Flask REST framework들 { #flask-rest-frameworks }

Flask REST framework는 여러 개가 있지만, 시간을 들여 조사해 본 결과, 상당수가 중단되었거나 방치되어 있었고, 해결되지 않은 여러 이슈 때문에 적합하지 않은 경우가 많았습니다.

### [Marshmallow](https://marshmallow.readthedocs.io/en/stable/) { #marshmallow }

API 시스템에 필요한 주요 기능 중 하나는 데이터 "<dfn title="마샬링, 변환이라고도 함">직렬화</dfn>"입니다. 이는 코드(Python)에서 데이터를 가져와 네트워크로 전송할 수 있는 형태로 변환하는 것을 의미합니다. 예를 들어 데이터베이스의 데이터를 담은 객체를 JSON 객체로 변환하거나, `datetime` 객체를 문자열로 변환하는 등의 작업입니다.

    which is an exception-throwing alternative to `MediaType.parse(String)`.
 *  New: The `EventListener` API previewed in OkHttp 3.9 has graduated to a stable API. Use this
    interface to track metrics and monitor HTTP requests' size and duration.
 *  New: `okhttp-dnsoverhttps` is an experimental API for doing DNS queries over HTTPS. Using HTTPS
