Nodejs 에서 puppeter 는 이벤트 로 HAR 데 이 터 를 캡 처 합 니 다.

먼저 cvs 파일 에서 분석 할 url 데 이 터 를 읽 은 다음 puppeter 와 puppeter - har 를 사용 하여 브 라 우 저의 HAR 데 이 터 를 가 져 옵 니 다.디 버 깅 과정 에서 for 순환 에서 어떻게 조작 하 는 지 모두 비동기 적 인 것 을 발 견 했 고 마지막 으로 해결 방안 을 찾 았 으 며 이 기록 에 도 포함 되 었 습 니 다.
1, csv 파일 을 분석 하 는 코드 만 들 기 (ultra - harlog / module / cvsresovle. js)
