java - 使用 Spring Security 进行 JWT 解码

Question

我在 JWT 解码方面遇到问题。我正在为 oauth2 授权服务编写集成。我发送请求以获取授权 token 并获得如下响应:

{
"access_token": "c76fb018-27c9-43f7-a751-62646eda7e1a-1",
"token_type": "Bearer",
"expires_in": 3600,
"refresh_token": "03e0be32-e72e-47ec-b740-a00b333a8ac4-1",
"id_token": "eyJhbGciOiJnb3N0MzQtMTAuMjAxMiJ9.eyJzdWIiOiIwZDYxNTI3NDRlNDhkMTU4Y2UwMWQ3ZDQwZTdjNzUwYmZhMTVmMWVhY2NkOTQ3YmYwYTU0NzRhNDkwMGMyZTdjIiwiaXNzIjoiaXNzLWRlZmF1bHQtdmFsdWUiLCJhdWQiOiIxMTQzIiwiZXhwIjoxNTE4NzAxMDcxLCJpYXQiOjE1MTg3MDA3NzEsImF1dGhfdGltZSI6MTUxODcwMDc1NiwiYWNyIjoibG9hLTMiLCJhbXIiOiJ7cHdkLCBtY2EsIG1mYSw

}

id_token - Base64 编码的 URL 是识别用户所需的一组客户端属性。属性以“.”分隔。字符，每个字符都必须单独解码。

我不知道怎么办。如果有任何帮助，我将不胜感激。

应用程序.yml

spring:
  security:
    oauth2:
      client:
        registration:
          sbb:
            client-id: *******
            client-secret: ******
            scope: openid
            client-authentication-method: post
            authorization-grant-type: authorization_code
            redirect-uri: '{baseUrl}/login/oauth2/code/{registrationId}'
        provider:
          sbb:
            authorization-uri: https://auth.site.com/ic/sso/api/v1/oauth/authorize
            token-uri: https://auth.site.com/ic/sso/api/v1/oauth/token
            user-info-uri: https://auth.site.com/ic/sso/api/v1/oauth/user-info
            user-name-attribute: sub

@Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.httpBasic().disable();
        http.cors().disable();
        http.csrf().disable();
        http
            .authorizeRequests().antMatchers("/login").permitAll().and()
            .authorizeRequests()
            .anyRequest()
            .authenticated()
            .and()
            .oauth2Login();
   }
}

当我启动我的应用程序时，出现错误:org.springframework.security.oauth2.core.OAuth2AuthenticationException:[missing_signature_verifier] 找不到用于客户端注册的签名 validator :'sbb'。检查以确保您已配置 JwkSet URI。

我的提供商不提供 JwkSet URI。

Filip 描述了这种方法 here .我只是稍微扩展了一下。

  @Bean
  public JwtDecoderFactory<ClientRegistration> jwtDecoderFactory() {

    final JwtDecoder decoder = new JwtDecoder() {

      @SneakyThrows
      @Override
      public Jwt decode(String token) throws JwtException {
        JWT jwt = JWTParser.parse(token);
        return createJwt(token, jwt);
      }

      private Jwt createJwt(String token, JWT parsedJwt) {
        try {
          Map<String, Object> headers = new LinkedHashMap<>(parsedJwt.getHeader().toJSONObject());
          Map<String, Object> claims = parsedJwt.getJWTClaimsSet().getClaims();
          return Jwt.withTokenValue(token)
              .headers(h -> h.putAll(headers))
              .claims(c -> c.putAll(claims))
              .build();
        } catch (Exception ex) {
          if (ex.getCause() instanceof ParseException) {
            throw new JwtException(String.format(DECODING_ERROR_MESSAGE_TEMPLATE, "Malformed payload"));
          } else {
            throw new JwtException(String.format(DECODING_ERROR_MESSAGE_TEMPLATE, ex.getMessage()), ex);
          }
        }
      }
    };
    return context -> decoder;
  }
