이 파일 말고도 static라는 파일도 있어야함
GET(서버로부터 정보를 조회하기 위해 설계된 메소드)
POST(리소스를 생성/변경하기 위해 설계된 메소드)
Get과 Post를 이용해서 이름과 같이 작성칸에 글자를 작성하면 밑에 표에 작성되는 것을 생성하였다
주의)처음에 html을
@app.route('/')
def homework():
return render_template('index.html')
여기와 다른 정보로 넣으면 flsak가 파일을 찾지 못해
jinja2.exceptions.TemplateNotFound
라는 문구가 뜰 수 있으므로 처음에 신경써서 잘 넣어야함
안녕하세요
