안녕하세요! 강의 정말 잘 듣고 있습니다~ 항상 감사합니다. 다름이 아니라, 로그인, 회원가입을 구현하던 중에 궁금증이 생겨 질문드립니다. 로그인이나 회원가입시 form을 통해 비밀번호를 서버로 보내면 request body에 비밀번호가 노출되어 전달되는데요, 이렇게 되면 보안상 위험이 있는것 아닌가 해서 숨길 수 있는 방법 혹은 암호화 해서 보낼 수 있는 방법이 있는지 문의 드립니다! 감사합니다.

안녕하세요 강사님 질 좋은 강의 항상 감사드립니다. 다름이 아니라 해당 강의의 7분 이후부터 실행의 오류가 떠서 제 나름대로 이전에 쓰던 Member 클래스를 삭제하지 않고 그대로 써서 있는 오류라 생각하고 import 해당 부분을 삭제 하고 다시 실행을 해보니 화면과 같이 몇 시간째 계속 구동만 하고 있습니다 ㅠㅠ 혹시 어떤 부분에서 이상이 생긴건지 알고 싶습니다. H2 데이터베이스도 다시 껐다 켜보니 테이블의 속성들과 엔티티들이 제대로 생성 되었으나 프로젝트가 제대로 실행이 안되네요.. 오전 4:23:06: Executing task 'JpashopApplication.main()'... Starting Gradle Daemon...

[리뉴얼] React로 NodeBird SNS 만들기

2. 사라집니다. 질문의 의도를 추측해보자면 take은 한 번 실행하고 더이상 실행이 안되는데 delay랑 Put은 왜 다음번에 되는지를 물어보시는 것 같은데요. watch 함수는 한 번만 실행되고 login* 함수같은 것은 매번 실행돼서 그렇습니다. 하나의 함수 안에서 더이상 호출이 안 되는거지 새로운 함수가 또 실행되면 새 함수 안에서는 실행됩니다. ============================================= 밑에 다른 분께서 올리신 질문중에 take와 다른 이펙트들에 대해서 질문한 글을 봤습니다. 저도 궁금한 점이 있어서요. watch 함수는 한 번만 실행하고 login* 함수는 매번 실행한다는 게 어떤 의미 일까요? 만약 로그인을 한다고 하였을때 watchLogin() --> Login() --> loginAPI() .. 1) 이런식으로 불리는데 어차피 take든 delay든 put이든 다 한 번만 불려서 한 번만 쓰고 버려지는 그런게 아닐까요? 2) 사실 한 번만 실행이 가능하다는건 이해를 했는데 그 의도가 이해가 안가네요. 그냥 take라는 이펙트 자체의 의도가 한 번만 실행하도록 한거고 여러번 눌릴것을 대비하여 takeLatest를 쓰면된다라고만 이해하면 될까요? 3) 그리고 take가 단 한번만 실행이 가능하다는 의미가 한 번 실행후에는 함수를 불러도 더 이상 실행이 안된다. 그러나 delay나 put같은경우에는 같은 함수를 실행하면 다시 실행된다. 이렇게 이해를 해야할까요. 감사합니다.

PyQt5로 계산기 만드는 프로그램 작성 중 구문 오류가 떴는데 무엇이 잘못된 건지 모르겠습니다.

미해결

PyQt5를 활용하여 계산기 만드는 프로그램을 작성 중에 SyntaxError: unexpected EOF while parsing 라는 에러 메시지가 떴습니다. 인터넷에 찾아보니 괄호나 철자가 틀렸을 경우 종종 뜨는 오류라고 하는데 어디가 잘못되었는지 전혀 모르겠습니다. QtDesigner에서 시그널/슬롯 편집은 따로 하지 않았고 객체들은 파이썬 파일에서 connect를 활용하여 모두 연동하였습니다. 파이썬에서 작성한 코드와 QtDesigner를 이용하여 작성한 내용은 다음과 같습니다. 혹시 제 코드 중 어디가 잘못되었는지 알려주실 수 있나요? import sys from PyQt5 .
