How do I redirect to a specific uri after Google oauth using Spring Boot - spring

Question

I'm implementing a server using Spring Boot. After the user do an oauth login, I want the user to go redirect to a specific uri so I can let the user register or login. The Google OAuth login seems like it is working fine but it keeps going to "/" uri. I want to user to be redirected to "/api/v1/member/oauth"
This is my Spring Security setup.
...
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.cors()
.and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers("/swagger-ui/**", "/swagger-resources/**", "/v2/api-docs")
.permitAll()
.anyRequest()
.permitAll()
.and()
.oauth2Login()
.defaultSuccessUrl("/api/v1/member/oauth")
.userInfoEndpoint()
.userService(customOAuth2MemberService);
}
...
This is the OAuth service that a user is directed to. (This works fine)
#Service
#RequiredArgsConstructor
public class CustomOAuth2MemberService implements OAuth2UserService<OAuth2UserRequest, OAuth2User> {
#Override
public OAuth2User loadUser(OAuth2UserRequest userRequest) {
OAuth2UserService<OAuth2UserRequest, OAuth2User> delegate = new DefaultOAuth2UserService();
OAuth2User oAuth2User;
try {
oAuth2User = delegate.loadUser(userRequest);
} catch (OAuth2AuthenticationException e) {
throw new CustomException(OAUTH_FAIL);
}
return new DefaultOAuth2User(oAuth2User.getAuthorities(), oAuth2User.getAttributes(), "sub");
}
}
I want to get the DefaultOAuth2User which is returned from the above to this uri.
#PostMapping("/api/v1/member/oauth")
public Object registerOrLogin(DefaultOAuth2User defaultOAuth2user) {
return ResponseEntity.status(200)
.body(DefaultResponseDto.builder()
.responseCode("MEMBER_LOGIN")
.build());
}
It currently is not going to this uri and is redirected to "/".
NEW: I redirected it by having .defaultSuccessUrl() but now the DefaultOAuth2User is not sent with the redirection, causing the parameter of redirected api to be null. How do I fix this problem?

Answer 1

Try to use
.oauth2Login()
.defaultSuccessUrl("/api/v1/member/oauth")
this should override post-authentication behavior and redirect to the desired page after successful login. Also, there is a similar method for setting redirection URL for failed authentication .failureUrl("url").

Answer 2

Spring-Security AbstractAuthenticationProcessingFilter class has successfulAuthentication() methos, which defines what happens when a User is successfully authenticated. You can register your success handler and put your redirect logic there.
But here is a catch, when using OAuth2.0, we need to specify redirect-uri to which user will be landed after client receives an access-token.
If you are okay with this Oauth's redirect-uri, do not alter the redirect in success handler or if you need to redirect irrespective of that, use response.sendRedirect("/social-login-sample/some-page");
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.cors()
.and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers("/swagger-ui/**", "/swagger-resources/**", "/v2/api-docs")
.permitAll()
.anyRequest()
.permitAll()
.and()
.oauth2Login()
.userInfoEndpoint()
.userService(customOAuth2MemberService)
.and()
.successHandler(
new AuthenticationSuccessHandler() {
#Override
public void onAuthenticationSuccess(
HttpServletRequest request,
HttpServletResponse response,
Authentication authentication)
throws IOException, ServletException {
// authentication.getName() : Principal Name
CustomOAuth2User oauthUser = (CustomOAuth2User) authentication.getPrincipal();
// Check if user is registered in your Database, if not, register new user
//userService.processAuthenticatedUser(oauthUser.getEmail());
// Get actual redirect-uri set in OAuth-Provider(Google, Facebook)
String redirectUri =
UriComponentsBuilder.fromHttpUrl(UrlUtils.buildFullRequestUrl(request))
.replaceQuery(null)
.build()
.toUriString();
log.info("redirectUri: {}", redirectUri);
// Ignore redirect-uri, and send user to a different page instead...
// response.sendRedirect("/social-login-sample/some-ther-page");
}
})
}
