솔직히 불만이 한두가지가 아닙니다. 아무리 싼 강의라 해도 2시간 남짓한 수업에 5만원 강의를 산건데 즉문즉답이 토일 2시부터 5시고, 강의도 잘 따라가다가 코드가 전 강의랑 다르다던지 심지어 7강에서는 코드스니펫에 POST API코드에는 @app.route('/exhibit', methods=["POST"])로 적어놓으시고 fetch API코드에는
let formData = new FormData()
formData.append("example_give", "data")
fetch('/target', {method: "POST", body: formData}).then(res => res.json()).then(data => {
console.log(data)
})
와 같이 적어놓으셔서 오류가 발생하더군요. 중간 강의를 날리신건지 옛날 강의랑 섞인건지 모르겠는데, 제대로 이어지는 강의를 제공해주셨으면 합니다. 코드 오류가 나도 제 잘못인지 강사님의 코드랑 달라서 오류가 난건지 스스로 판단이 힘듭니다.
이와 별개로 8차시 강의를 듣던 중 오류가 발생했습니다.
코드는 강의 잘 따라가며 썼는데 forEach문을 시행하던 중 콘솔창에서 데이터를 못 받아오는 듯 하더군요.
콘솔창과 index.html, app.py, app.py 실행 후 새로고침 시 뜨는 메시지 첨부합니다.
