- jquery: javaScript 기반으로 만들어 진 라이브러리
- jquery에서는 원하는 HTML의 DOM 요소를 찾기위해 $(selector)와 같은 표현식 사용
- JSON: 인터넷에서 자료를 주고 받을 때 쓰는 문법
- requests: 클라이언트쪽에서 url을 전송 = 이 주소의 정보를 달라고 서버에 요청 -> 서버는 response를 통해 정보를 준다. 이때 브라우저는 ajax(화면갱신없이 변경되는 데이터를 받아오는 것 )
- api: 브라우저와 서버의 창구
- GET과 POST는 request의 형식
- bs4를 통해 웹스크롤링(원하는 정보 받아와)
- 어떠한 url만 입력했는게 자동으로 불려와 지는 부분들:meta tag/
meta tag를 bs4를 사용하여 스크래핑할때 기존의 스크래핑 형식과 달리 해야 함(alonememo app.py참조 )
