Flask 프레임워크를 활용해 API만들기, 미니프로젝트1, 2

Flask

  • 기본 폴더구조
  • 프로젝트폴더
    ㄴstatic 폴더 (이미지, css파일을 넣어둡니다)
    ㄴtemplates 폴더 (html파일을 넣어둡니다)
       ㄴindex.html
    ㄴapp.py 파일

API 만들기

  • GET, POST 방식
    -- GET : 데이터 조회(Read)를 요청할 때
         → 데이터 전달 : URL 뒤에 물음표를 붙여 key=value로 전달
         → 예: google.com?q=북극곰
    -- POST : 데이터 생성(Create), 변경(Update), 삭제(Delete) 요청 할 때
         → 예) 회원가입, 회원탈퇴, 비밀번호 수정
         → 데이터 전달 : 바로 보이지 않는 HTML body에 key:value 형태로 전달

4주차 회고

똑같은 페이지에 기능이 하나하나 늘어가는 건 신기해! mongoDB도 다루면서 실시간으로 이루어지는 거랑 바로바로 적용이 되는 것 신기하다! 실시간으로 볼 수 있고 어떤 코드로 어떤 기능이 실행이 되는지 알 수 있으니 점점 더 재밌어진다 5주차까지 화이팅!
