플라스크에 request.args.get ('next') 값이 사라졌습니다.

Question

플라스크에있는 Miguel sir 님의 책을 팔로우하고 있습니다. 사용자에게 전자 메일 확인을 보내고 로그인을 요청한 링크를 클릭했지만 로그인 한 후 request.args.get ('next') 변수가 비어있는 로그인 기능이 작동하지 않습니다. 확인 기능이 실행되지 않습니다. 나는 이것이 before_app_request로 인한 것 같아. 나는 술병에 아주 익숙해졌으며 이틀을 보냈습니다. Miguels 버전은 잘 작동하고, 내 것은 저주받은 것 같습니다. 다른 사람의 견해가 정말로 필요합니다. 읽어 주셔서 감사합니다.
