안녕하세요. 9장강의를 듣고 추가 과제를 시도해보던 중 궁금증이 생겨 질문드립니다.스스로 해보기 -> 팔로잉 끊기에서 destory와 라우터를 사용하라고 안내해주셨는데 user자체를 삭제하는 것이 아닌 중간테이블(follow)에서 해당 로우만 삭제하는 방법이 따로 있나요? if (user) { const a = await user.destroy({ where: { Followings: { followerId: req.params.id } }, });위와 같이 방법을 여러가지로 시도해보았지만 계속해서 유저 삭제(탈퇴)가 되는 상황이라 도움주시면 감사하겠습니다..!

안녕하세요. 강사님! 수업 정말 잘 들었습니다! 비전공자로써 3개월째인데 JWT 강의 중에 정말 이해가 잘 되었습니다!!! 진심으로 감사합니다~~다름이 아니라 더 나아가서, JWT와 Oauth2를 붙이려고 하는데 JWT 강의 초반에 기존의 Oauth2 방식을 사용하지 않고 다른 방식을 써야 된다고 하셔서 질문합니다.어떤 부분이 달라져야할지 전혀 감이 안 오는데, 제가 조금 참고할만한 자료가 있을까요? 혹시 JWT+Oauth를 붙이려고 할 때 코드가 많이 변경될까요?(혹시 강의 제작하실 생각 없으신가요...ㅎㅎ)

[코드](https://github.com/YuYoHan/JWT)ECDSA signing keys must be PrivateKey instances.이런 오류가 뜨는데 JwtProvider입니다. @Slf4j @Component public class JwtProvider implements InitializingBean { private static final String AUTHORITIES_KEY = "auth"; private final String secret; private final long tokenValidityInMilliseconds; private Key key; public JwtProvider(@Value("${jwt.secret_key}") String secret, @Value("${jwt.access.expiration}") long tokenValidityInMilliseconds ) { this.secret = secret; this.tokenValidityInMilliseconds = tokenValidityInMilliseconds * 1000; } // 여기서 InitializingBean를 상속받고 이 메소드를 오버라이드한 이유는 // Bean이 생성이 되고 생성자를 통해서 secret 값을 Base64 Decode해서 key 변수에 할당하기 위함이다. @Override public void afterPropertiesSet() throws Exception { byte[] keyBytes = Decoders.BASE64.decode(secret); this.key = Keys.hmacShaKeyFor(keyBytes); } // 유저 정보를 가지고 AccessToken, RefreshToken을 생성하는 메서드 public TokenDTO createToken(Authentication authentication) { // 권한 가져오기 String authorities = authentication.getAuthorities().stream() .map(GrantedAuthority::getAuthority) .collect(Collectors.joining(",")); long now = (new Date()).getTime(); // Access Token 생성 Date accessTokenExpire = new Date(now + this.tokenValidityInMilliseconds); String accessToken = Jwts.builder() .setSubject(authentication.getName()) .claim(AUTHORITIES_KEY, authorities) .setExpiration(accessTokenExpire) .signWith( key, SignatureAlgorithm.ES512) .compact(); // Refresh Token 생성 Date refreshTokenExpire = new Date(now + this.tokenValidityInMilliseconds + 86400); String refreshToken = Jwts.builder() .setSubject(authentication.getName()) .claim(AUTHORITIES_KEY, authorities) .setExpiration(refreshTokenExpire) .signWith(key, SignatureAlgorithm.ES512) .compact(); return TokenDTO.builder() .grantType("Bearer") .accessToken(accessToken) .refreshToken(refreshToken) .build(); } // JWT 토큰을 복호화하여 토큰에 들어있는 정보를 꺼내는 코드 // 토큰으로 클레임을 만들고 이를 이용해 유저 객체를 만들어서 최종적으로 authentication 객체를 리턴 // 인증 정보 조회 public Authentication getAuthentication(String token) { // 토큰 복호화 메소드 Claims claims = parseClaims(token); if(claims.get("auth") == null) { throw new RuntimeException("권한 정보가 없는 토큰입니다."); } // 클레임 권한 정보 가져오기 Collection<? extends GrantedAuthority> authorities = Arrays.stream(claims.get(AUTHORITIES_KEY).toString().split(",")) .map(SimpleGrantedAuthority::new) .collect(Collectors.toList()); // UserDetails 객체를 만들어서 Authentication 리턴 User principal = new User(claims.getSubject(), "", authorities); return new UsernamePasswordAuthenticationToken(principal, token, authorities); } private Claims parseClaims(String token) { try { return Jwts.parserBuilder() .setSigningKey(key) .build() .parseClaimsJws(token) .getBody(); } catch (ExpiredJwtException e) { return e.getClaims(); } } // 토큰의 유효성 검증을 수행 public boolean validateToken(String token) { try { Jwts.parserBuilder().setSigningKey(key).build().parseClaimsJws(token); return true; } catch (io.jsonwebtoken.security.SecurityException | MalformedJwtException e) { log.info("잘못된 JWT 서명입니다."); } catch (ExpiredJwtException e) { log.info("만료된 JWT 토큰입니다."); } catch (UnsupportedJwtException e) { log.info("지원되지 않는 JWT 토큰입니다."); } catch (IllegalArgumentException e) { log.info("JWT 토큰이 잘못되었습니다."); } return false; } } 강의랑 같은데 오류가 발생하네요 ㅠㅠ 

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

package.json에서 "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 출력되는데설정을 추가 하면 아래처럼 promise가 더 먼저 출력됩니다.이러한 결과에 대한 원인이 궁금합니다!! 

PrincipalDetails시큐리티가 /login을 낚아채서 로그인을 진행시킨다.PrincipalDetailsService시큐리티 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?

public class User { @Id @Column(name = "user_id") @GeneratedValue(strategy = GenerationType.IDENTITY) private Long userId; @Column(name = "username", length = 50, unique = true) private String

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

언제 db에 값을 넣었나요? 강의중에 넣은 영상을 본적이 없었던 것 같아서요

컨트롤러와 서비스에 NotFoundException을 둘다 작성하셨는데 혹시 필요없는 로직이 아닌지 생각됩니다.컨트롤러에서 데이터를 받았는데 서비스로 데이터가 안넘어 갈일은 없다고 생각되서요꼭 필요한 코드인지 의문입니다.

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.

안녕하세요. 좋은 강의 만들어주셔서 감사합니다.강의 마지막 내용 중, A가 B에게 보낼 내용을 B의 공개키로 잠근 후 그 후에 A의 비밀키로 잠그면 B는 A의 공개키로 연 후에, B의 비밀키로 해당 문서를 복호화 하는 것까지는 이해했습니다. 여기서 궁금한 게 하나 생기는데, A의 공개키는 누구나 다운받을 수 있으니 해커도 다운받을 수 있으므로 A의 공개키로 해커가 복호화한 후 데이터를 날려버리고 새로운 데이터를 B에게 보낼 수 도 있는게 아닌가요?? 살짝 전의 내용에서 해커가 데이터를 가로채 데이터를 날려 새로운 데이터를 보낼 수 있다다는 것을 보고 궁금증이 생겼습니다.
