자동 로그인 파이썬 치루 대학 상원 광장 레거시 시스템을 사용하여 자신의 성적표를 얻을

간단한 설명을 처리 : 세션을 작성,이 세션을 사용하는 요청을 보냅니다. 요청 패킷 필드는 간단합니다, 로그인 요청 패킷 분석은 동적 코드뿐만 아니라, 조금 이해할 수. 로그인 요청 패킷을 분석함으로써, 나는 메시지 동적 코드가 너무 동적 프런트 엔드 코드가 매우 중요합니다 수, 동적으로 생성 된 헤더, 프런트 엔드 코드의 방문 페이지에 숨겨진이 동적 코드를 필요로 발견했다. 성공적으로 로그인 한 후, 상태가 성공적으로 로그인 세션에 저장됩니다, 당신은 어떤 정보에 액세스하기 위해이 세션을 사용할 수 있습니다.

참고 :이 검증 사진이 자동으로 현재 폴더에 다운로드되어 수동으로 인증 코드를 입력해야합니다.

다음과 같이 코드가 실행된다 :
