* 항상 DB(MongoDB사용)를 준비한다.
* 새 프로젝트를 열고, static 과 templates 디렉토리 생성
* app.py생성, templates 안에 index.html 생성
* 패키지설치: flask, BS4, dnspython, pymongo, requests
POST연결
1. 요청정보: URL=/homework, 요청방식=POST2. 클라이언트(Ajax) >> 서버(Flask): name, comment3. 서버(Flask) >> 클라이언트(Ajax): 메시지보냄(입력완료)
GET연결
1. 요청정보: URL=/homework, 요청방식=GET2. 클라이언트(Ajax)>>서버(Flask): 없음3. 서버(Flask)>>클라이언트(Ajax): 전체데이터보내주기
-서버 만들기: 여러개 찾기 코드 활용
all_users = list(db.users.find({},{'_id':False}))-클라이언트 만들기: 클라이언트는 가져갈 데이터가 없음

-value값 여러개 나열시, 쉼표사용하지 않기let name = $('#name').val()let commnet = $('#comment').val()
-새로고침기능window.location.reload()
-for문에 해당 괄호 사용할 것 ()
