在使用Google进行身份验证时，从Spring OAuth2授权服务器发出JWT令牌

Question

我想使用Spring Oauth创建一个授权服务器，它可以发布自己的JWT令牌。授权服务器必须将身份验证委派给Google。我一直在关注本教程，它几乎可以完成我想要的一切：https://spring.io/guides/tutorials/spring-boot-oauth2/

我能够将Google添加为身份验证提供程序，但我正在努力应对JWT部分。

这是我的授权服务器配置：

@SpringBootApplication 
@EnableOAuth2Client
@EnableAuthorizationServer
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class MsAuthorizationGmailApplication extends WebSecurityConfigurerAdapter {

    @Autowired
    OAuth2ClientContext oauth2ClientContext;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.antMatcher("/**").authorizeRequests().antMatchers("/", "/login**", "/webjars/**").permitAll().anyRequest()
            .authenticated().and().exceptionHandling()
            .authenticationEntryPoint(new LoginUrlAuthenticationEntryPoint("/login/gmail")).and().logout()
            .logoutSuccessUrl("/").permitAll().and().csrf()
            .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()).and()
            .addFilterBefore(ssoFilter(), BasicAuthenticationFilter.class);
    }

    @Bean
    @ConfigurationProperties("gmail")
    public ClientResources gmail() {
        return new ClientResources();
    }

    private Filter ssoFilter() {
        CompositeFilter filter = new CompositeFilter();
        List<Filter> filters = new ArrayList<>();
        filters.add(ssoFilter(gmail(), "/login/gmail"));
        filter.setFilters(filters);
        return filter;
    }

    private Filter ssoFilter(ClientResources client, String path) {
        OAuth2ClientAuthenticationProcessingFilter filter = new     OAuth2ClientAuthenticationProcessingFilter(
            path);
        OAuth2RestTemplate template = new OAuth2RestTemplate(client.getClient(), oauth2ClientContext);
        filter.setRestTemplate(template);
        filter.setTokenServices(JwtConfig.tokenServices());
        return filter;
    }

    public static void main(String[] args) {
        SpringApplication.run(MsAuthorizationGmailApplication.class, args);
    }

}

在JWT配置中，我不是想做任何花哨的事情，只是试图让它现在通过：

public final class JwtConfig {

    private static final String KEY = "123";

    private JwtConfig() {
    }

    private static JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setSigningKey(KEY);
        return converter;
    }

    private static TokenStore tokenStore() {
        return new JwtTokenStore(accessTokenConverter());
    }

    public static DefaultTokenServices tokenServices() {
        DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
        defaultTokenServices.setTokenStore(tokenStore());
        defaultTokenServices.setSupportRefreshToken(true);
        return defaultTokenServices;
    }
}

我得到以下异常：

我是如何理解的：看起来当Google发出访问令牌时，授权服务器（作为Google OAuth的客户端）会尝试将访问令牌解码为JWT，并抛出异常，因为Google的令牌不是有效的JWT（它只是一个访问令牌）。

我想创建一个包含访问令牌（将用于访问Google API）的JWT以及有关该用户的一些其他信息。我还希望能够在访问令牌到期时刷新JWT令牌。有没有办法实现这个目标？

我不确定GMail，但对于您自己的授权服务器，您可以添加一个令牌增强器JwtAccessTokenConverter，它会将您的令牌转换为JWT。

如需样品，请参阅oauth2-spring-boot-mongo-jwt-sample

通常，正常令牌有效载荷属于以下类型

{
    "access_token": "bc9c021f-b5ae-43af-9746-737b533f9bc5",
    "token_type": "bearer",
    "refresh_token": "fee7a2a1-eff9-4757-8dd3-5392ee225bea",
    "expires_in": 43199,
    "scope": "read-foo" }

然而，JWT看起来像这样

{
    "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsiZm9vIl0sInVzZXJfbmFtZSI6InVzZXIiLCJzY29wZSI6WyJyZWFkLWZvbyJdLCJleHAiOjE1MTQ3ODMwNTIsImF1dGhvcml0aWVzIjpbIlJPTEVfVVNFUiJdLCJqdGkiOiJlMjM4MDg1YS0xZjFjLTQ5ZWQtODNiMC1iN2Q1MjI5OWUwZjYiLCJjbGllbnRfaWQiOiJ3ZWItY2xpZW50In0.-OSw1Vr4o1dnAQL3n7QFGG6UOXr4itc0Kp8dugyT4zU",
