spring - 如何在 Rest 模板中重用用户 (authorization_code) 的 oauth2 token

Question

我有 3 个应用程序

1. 前端应用
2. OAuth2 身份验证服务器
3. REST API(RepositoryRestResources)

我的用户必须先登录才能使用前端应用程序。这是通过 SSO 实现的。他们会收到一个 token ，该 token 在被允许进入之前由客户端验证。

我想重用此 token 来发出 api 请求。我的 REST api 应用程序使用相同的 SSO 登录(它是前端客户端的资源)来保护安全，但我不知道如何“添加授权 header ”以在我用于 api 请求的 RestTemplate 中使用。

我像这样创建我的restTemplate:

public static RestTemplate build()
    {
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        mapper.registerModule(new Jackson2HalModule());
        mapper.registerModule(new JavaTimeModule());
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converter.setSupportedMediaTypes(MediaType.parseMediaTypes("application/hal+json"));
        converter.setObjectMapper(mapper);
        return new RestTemplate(Arrays.asList(converter));
    }

我的资源服务器配置:

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter
{

    @Value("${resource.id}")
    private String resourceId;

    @Override
    public void configure(HttpSecurity http) throws Exception
    {
        http
                .authorizeRequests()
                .antMatchers(HttpMethod.OPTIONS).permitAll()
                .anyRequest().authenticated()
                .and().exceptionHandling().accessDeniedHandler(new OAuth2AccessDeniedHandler());
    }

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception
    {
        resources.resourceId(resourceId);
    }


    @Bean
    public static TokenEnhancer tokenEnhancer()
    {
        return new JwtTokenEnhancer();
    }


    @Bean
    public static JwtAccessTokenConverter accessTokenConverter()
    {
        KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(new ClassPathResource("keystore.jks"), "somesecret".toCharArray());
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();

        converter.setKeyPair(keyStoreKeyFactory.getKeyPair("pair"));
        return converter;
    }

    @Bean
    public static TokenStore tokenStore()
    {
        return new JwtTokenStore(accessTokenConverter());
    }

}

我使用拦截器修复了它，并从安全上下文中手动添加 token 。

RestTemplate restTemplate = new RestTemplate();
restTemplate.getInterceptors().add(new OAuthInterceptor());

其中拦截器定义为:

public class OAuthInterceptor implements ClientHttpRequestInterceptor
{

    @Autowired
    private AuthenticationHolder holder;

    @Override
    public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException
    {
        if (holder.getToken() == null)
        {
            //throw new IOException("Token not set");
            System.out.println("##################### Token not set! ###################");
        }
        else
        {
            System.out.println("##################### Token found: " + holder.getToken());
            HttpHeaders headers = request.getHeaders();
            headers.add(HttpHeaders.AUTHORIZATION, "Bearer " + holder.getToken());
        }

        return execution.execute(request, body);
    }
}

我使用在客户端应用程序中实现的接口(interface):

public interface AuthenticationHolder
{
    String getToken();
}

@Bean
public AuthenticationHolder getAuthenticationHolder()
{
    return () ->
    {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if(authentication != null && authentication.getDetails() instanceof OAuth2AuthenticationDetails)
        {
            return ((OAuth2AuthenticationDetails) authentication.getDetails()).getTokenValue();
        }
        return null;
    };
}
