JWT 에러

미해결

ECDSA signing keys must be PrivateKey instances. 이거는 대체 무슨에러죠 ? ㅠㅠ 해결방법이 안나오네요 ㅠㅠ

nextTick과 promise 우선순위에 대한 "type": "module"의 영향

미해결

[개정3판] Node.js 교과서 - 기본부터 프로젝트 실습까지

package.json 에서 "type": "module" 설정 유무에 따라 우선 순위가 다르게 나오는 이유가 궁금합니다. setImmediate(() => { console.log("immediate"); }); process.nextTick(() => { console.log("nextTick"); }); setTimeout(() => { console.log("timeout"); }, 0); Promise.resolve().then(() => console.log("promise")); 위의 코드로 설정없이 실행 시 강의 처럼 동일한 결과가 출력되는데 설정을 추가 하면 아래처럼 promise가 더 먼저 출력됩니다. 이러한 결과에 대한 원인이 궁금합니다!!

PrincipalDetails, PrincipalDetailsService에 대한 질문

해결됨

스프링부트 시큐리티 & JWT 강의

PrincipalDetails 시큐리티가 /login을 낚아채서 로그인을 진행시킨다. PrincipalDetailsService 시큐리티 설정에서 loginProcessingUrl("/login") 처리 이게 view를 리턴하는 방식에서는 formLogin을 처리해줘서 이렇게 여기서 작성하면 controller에서 기능을 구현하지 않아도 login을 시큐리티가 알아서 해주는 걸로 알고 있는데요. 그러면 REST API 방식일때는 SecurityConfig에 formLogin.disable()로 처리하는 걸로 알고 있는데 그러면 PrincipalDetails, PrincipalDetailsService은 REST 방식에서는 작성하지 않는건가요? 근데 그러면 의문이 저 2개의 클래스를 생성하지 않으면 @Data public class PrincipalDetails implements UserDetails, OAuth2User { private User user; private Map<String, Object> attributes; // 일반 로그인 public PrincipalDetails(User user) { this.user = user; } // Oauth 로그인 public PrincipalDetails(User user, Map<String, Object> attributes) { this.user = user; this.attributes = attributes; } // 해당 User의 권한을 리턴하는 곳 @Override public Collection<? extends GrantedAuthority> getAuthorities() { Collection<GrantedAuthority> collection = new ArrayList<>(); collection.add(new GrantedAuthority() { @Override public String getAuthority() { return user.getRole(); } }); return collection; } // 사용자의 패스워드를 반환 @Override public String getPassword() { return user.getPassword(); } @Override public String getUsername() { return user.getEmail(); } // 계정 만료 여부 반환 @Override public boolean isAccountNonExpired() { // 만료되었는지 확인하는 로직 // true = 만료되지 않음 return true; } // 계정 잠금 여부 반환 @Override public boolean isAccountNonLocked() { // true = 잠금되지 않음 return true; } // 패스워드의 만료 여부 반환 @Override public boolean isCredentialsNonExpired() { // 패스워드가 만료되었는지 확인하는 로직 // true = 만료되지 않음 return true; } // 계정 사용 가능 여부 반환 @Override public boolean isEnabled() { // 계정이 사용 가능한지 확인하는 로직 // true = 사용 가능 return true; } @Override public Map<String, Object> getAttributes() { return attributes; } @Override public String getName() { return null; } } 여기서 UserDtails, OAuth2User을 상속받아서 Override하는 부분은 어떻게 구현하나요?

.username(userDto.getUsername()) .password(passwordEncoder.encode(userDto.getPassword())) .nickname(userDto.getNickname()) .authorities(Collections.singleton(userAuthority)) .activated(true) .build(); return userRepository.save(user); } UserService는 중간에 UserAuthority로 빌드하는 것을 추가해줬습니다. private org.springframework.security.core.userdetails.User createUser(String username, User user, UserAuthority userAuthority) { if (!user.isActivated()) { throw new RuntimeException(username + " -> 활성화되어 있지 않습니다."); } List<GrantedAuthority> grantedAuthorities = user.getAuthorities().stream() .map(authority -> new SimpleGrantedAuthority(authority.getAuthority().getAuthorityName())) .collect(Collectors.toList()); return new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(), grantedAuthorities); } CustomUserDetailService도 String 타입으로 일치 해야 함으로 authority.getAuthorityName() 을 authority.getAuthority().getAuthorityName()) 로 변환해주었습니다. 이후 data.sql의 admin 아이디는 모든 메서드가 잘 되는데 signup으로 회원가입후 getUesr메서드시 권한정보가 넘어오지 못했다는 오류가 발생합니다. 2023-06-02 00:43:56.952 ERROR 18668 --- [nio-8080-exec-7] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet

Django REST Framework 핵심사항

안녕하세요. 강의는 잘 들었습니다. 강의와 관련이 없지만 해답을 찾지 못해 이렇게 남깁니다.. 다름이 아니라 제가 jwt token을 사용하여 프로젝트를 구현을 했습니다. 제가 알고 있는 것은 jwt token을 사용하게 되면 csrf token이 필요없기 때문에 발급하면 안되는 것으로 알고 있습니다. 그래서 X-CSRFToken을 발급하지 못하게 하고 싶은데 검색해도 찾지 못했습니다. 일단 제가 해본 것으로는 settings.py -> 'django.middleware.csrf.CsrfViewMiddleware' 을 주석처리. dj-rest-auth -> REST_AUTH 설정. 이 있습니다. 토큰에 대해 잘못알고 있거나 어딜 수정하면 될지 피드백을 주시면 감사하겠습니다.
