===== API Test =====
  * [[rest_api:httpbin|httpbin]] : 서버를 제공해주고 있음.
  * [[rest_api:json_server|Json Server]]
  * [[rest_api:jsonplaceholder|JSONPlaceHolder]]
  * https://reqbin.com/
  * https://docs.postman-echo.com/?version=latest
  * https://github.com/EsperoTech/yaade

===== 응답 코드 =====
  * ''5xx'' : 서버에 네트워크 커넥션등 어떤 물리적인 문제가 생겼을 때. 이 경우 재시도하면 복구 가능성이 있을 때 ''5xx'' 오류를 주는게 나아보임.
  * ''4xx'' : 애플리케이션 로직의 오류 혹은 요청 자체에 문제가 있을 때. 즉, 코드를 잘못짰을 때. 이 경우 재시도 해도 결과가 동일하게 잘못되는 상황. 따라서 ''4xx'' 는 재시도 하지 말라는 명확한 신호.
