使用帶有OpenID Connect提供程序的spring-security-oauth2客戶端時，如何訪問“id_token”和“refresh_token”？

Question

我已成功將Spring Security OAuth2與我的Open ID Connect提供程序（Forgerock OpenAM）集成。 我可以看到正在檢索的訪問令牌。 如何從/token端點訪問作為響應一部分的id_token和refresh_token ？

Answer 1

最后找出答案和發布，以防它對有相同問題的人有用。 會話通過Spring Security OAuth2進行Authentication ，會有一個Authentication對象設置。 它需要轉換為OAuth2Authentication的實例。 該對象具有令牌。

    Authentication auth = SecurityContextHolder.getContext().getAuthentication();
    if (auth instanceof OAuth2Authentication) {
        Object details = auth.getDetails();
        OAuth2AccessToken token = oauth2Ctx.getAccessToken();

        if (token != null && !token.isExpired()) {
            // Do Stuff
        }

Answer 2

一個替代方法的完整示例（使用Spring Boot並禁用其自動配置的一部分）。

application.properties：

security.oauth2.client.client-id=client-id
security.oauth2.client.client-secret=client-secret
security.oauth2.client.access-token-uri=http://my-oidc-provider/auth/oauth2/token
security.oauth2.client.user-authorization-uri=http://my-oidc-provider/auth/oauth2/authorize
security.oauth2.resource.token-info-uri=http://my-oidc-provider/auth/oauth2/check_token
security.oauth2.client.scope=openid,email,profile
security.oauth2.resource.jwk.key-set-uri=http://my-oidc-provider/auth/oidc/jwks

/**
 * Extending the AuthorizationServerEndpointsConfiguration disables the Spring
 * Boot ResourceServerTokenServicesConfiguration.
 */
@Configuration
@EnableOAuth2Sso
public class OAuth2Config extends AuthorizationServerEndpointsConfiguration {

    @Value("${security.oauth2.resource.jwk.key-set-uri}")
    private String keySetUri;

    @Value("${security.oauth2.resource.token-info-uri}")
    private String checkTokenEndpointUrl;

    @Value("${security.oauth2.client.client-id}")
    private String clientId;

    @Value("${security.oauth2.client.client-secret}")
    private String clientSecret;

    @Bean
    public RemoteTokenServices resourceServerTokenServices() {
        RemoteTokenServices tokenService = new RemoteTokenServices();

        DefaultAccessTokenConverter accessTokenConverter = new DefaultAccessTokenConverter();
        accessTokenConverter.setUserTokenConverter(new CustomIdTokenConverter(keySetUri));
        tokenService.setAccessTokenConverter(accessTokenConverter);

        tokenService.setCheckTokenEndpointUrl(checkTokenEndpointUrl);
        tokenService.setClientId(clientId);
        tokenService.setClientSecret(clientSecret);

        return tokenService;
    }

    @Bean
    public ClientDetailsService clientDetailsService() {
        return new InMemoryClientDetailsService();
    }

    @Bean
    public UserInfoRestTemplateFactory userInfoRestTemplateFactory(
            ObjectProvider<List<UserInfoRestTemplateCustomizer>> customizers,
            ObjectProvider<OAuth2ProtectedResourceDetails> details,
            ObjectProvider<OAuth2ClientContext> oauth2ClientContext) {
        return new DefaultUserInfoRestTemplateFactory(customizers, details,
                oauth2ClientContext);
    }
}

public class CustomIdTokenConverter extends DefaultUserAuthenticationConverter {

    private final JwkTokenStore jwkTokenStore;

    public CustomIdTokenConverter(String keySetUri) {
        this.jwkTokenStore = new JwkTokenStore(keySetUri);
    }

    @Override
    public Authentication extractAuthentication(Map<String, ?> map) {

        String idToken = (String) map.get("id_token");

        OAuth2AccessToken token = jwkTokenStore.readAccessToken(idToken);

        Map<String, Object> claims = token.getAdditionalInformation();
        OAuth2RefreshToken refreshToken = token.getRefreshToken();

        String principal = (String) claims.get("sub");

        List<GrantedAuthority> authorities = AuthorityUtils.createAuthorityList("ROLE_USER");

        return new CustomAuthenticationData(principal, claims, authorities);
    }
}

public class CustomAuthenticationData extends UsernamePasswordAuthenticationToken {

    private final Map<String, Object> attributes;

    public CustomAuthenticationData(String username, Map<String, Object> attributes, Collection<? extends GrantedAuthority> authorities) {
        super(username, "N/A", authorities);
        this.attributes = attributes;
    }

    public Map<String, Object> getAttributes() {
        return attributes;
    }
}
