spring-boot - 使用 spring-boot-starter-oauth2-client 检索 OAuth2 3 足身份验证的访问 token

Question

我想知道如何使用org.springframework.boot:spring-boot-starter-oauth2-client提供的功能在Spring Boot 3足身份验证上检索访问 token

我可以使用常规 RestTemplate 获取访问 token 来电。

我尝试使用 spring-boot-starter-oauth2-client 获取相同的访问 token 按照https://github.com/wonwoo/spring-boot-oauth2-login中的示例操作.

我能够检索服务器提供的代码，但我不知道如何获取访问 token 。

我的代码如下所示:

application.properties 中的属性:

spring.security.oauth2.client.registration.my-client-name-here.client-id=__client_id_here__
spring.security.oauth2.client.registration.my-client-name-here.client-secret=__client_secret_here__
spring.security.oauth2.client.registration.my-client-name-here.authorization-grant-type=authorization_code
spring.security.oauth2.client.registration.my-client-name-here.redirect-uri-template=http://localhost:8080/authentication/3leggedtoken/callback
spring.security.oauth2.client.registration.my-client-name-here.scope=data:read
spring.security.oauth2.client.registration.my-client-name-here.client-name=__client_name_here__
spring.security.oauth2.client.registration.my-client-name-here.client-authentication-method=POST
spring.security.oauth2.client.provider.my-client-name-here.token-uri=https://example.com/api/token
spring.security.oauth2.client.provider.my-client-name-here.authorization-uri=https://example.com/api/authorize
spring.security.oauth2.client.provider.my-client-name-here.user-info-uri=
spring.security.oauth2.client.provider.my-client-name-here.user-name-attribute=

Thymeleaf 模板位于 login.html :

<div th:each="registration: ${registrations}">
  <a th:href="@{${registration.uri}}">
      Sign in with [[${registration.clientName}]]
  </a>
</div>

SecurityConfig.java中的配置:

@Configuration
@EnableWebSecurity
public class SegurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http_security) throws Exception {
        http_security.authorizeRequests().requestMatchers(PathRequest.toStaticResources().atCommonLocations())
                .permitAll().antMatchers("/authentication/**").permitAll().anyRequest().authenticated().and().oauth2Login()
                .loginPage("/authentication/login").permitAll();
    }
}

AuthenticationController.java 中的 Controller :

@Controller
public class AuthenticationController {

    @Autowired
    OAuth2AuthorizedClientService clientService;

    @Autowired
    InMemoryClientRegistrationRepository clientRegistrationRepository;

    @GetMapping("authentication/login")
    public String login(Model model) {
        List<Registration> registrations = StreamSupport.stream(clientRegistrationRepository.spliterator(), true)
                .map(clientRegistration -> new Registration(clientRegistration.getRegistrationId(),
                        OAuth2AuthorizationRequestRedirectFilter.DEFAULT_AUTHORIZATION_REQUEST_BASE_URI + "/"
                                + clientRegistration.getRegistrationId(),
                        clientRegistration.getClientName()))
                .collect(Collectors.toList());
        model.addAttribute("registrations", registrations);
        return "authentication/login";
    }

    @GetMapping("authentication/3leggedtoken/callback")
    public String accessToken(Model model, @RequestParam("code") String code) {     
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (authentication.getClass().isAssignableFrom(OAuth2AuthenticationToken.class)) {
            OAuth2AuthenticationToken oauthToken = (OAuth2AuthenticationToken) authentication;
            String clientRegistrationId = oauthToken.getAuthorizedClientRegistrationId();
            OAuth2AuthorizedClient client = clientService.loadAuthorizedClient(clientRegistrationId,
                    oauthToken.getName());
            return client.getAccessToken().getTokenValue();
        }
        return null;
    }

应用程序成功创建到服务器身份验证页面的链接，并在登录后回调重定向 URI。

回调中返回的代码正确

public String accessToken(Model model, @RequestParam("code") String code) {...}

但身份验证的类型不是 OAuth2AuthenticationToken

Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

但是类型为AnonymousAuthenticationToken

org.springframework.security.authentication.AnonymousAuthenticationToken@ef72fdb1:
   Principal: anonymousUser; Credentials: [PROTECTED]; Authenticated: true;
   Details: org.springframework.security.web.authentication.WebAuthenticationDetails@b364:
       RemoteIpAddress: 0:0:0:0:0:0:0:1; SessionId: D8FFF6F20C14791E505B8B86648F7E1B;
       Granted Authorities: ROLE_ANONYMOUS

我应该如何获取访问 token ？我应该如何访问它以将其传递给以下请求？

提前致谢!

尝试删除@GetMapping("authentication/3leggedtoken/callback")端点并将其注册为bean。像这样:

import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.oauth2.client.OAuth2AuthorizedClient;
import org.springframework.security.oauth2.client.OAuth2AuthorizedClientService;
import org.springframework.security.oauth2.client.authentication.OAuth2AuthenticationToken;
import org.springframework.web.context.annotation.RequestScope;

import sample.api.facebook.Facebook;

@Configuration
public class SocialConfig {

    private final static Logger LOG = LoggerFactory.getLogger(SocialConfig.class);

    @Bean
    @RequestScope
    public Facebook facebook(OAuth2AuthorizedClientService clientService) {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        String accessToken = null;
        if (authentication.getClass().isAssignableFrom(OAuth2AuthenticationToken.class)) {
            OAuth2AuthenticationToken oauthToken = (OAuth2AuthenticationToken) authentication;
            String clientRegistrationId = oauthToken.getAuthorizedClientRegistrationId();
            if (clientRegistrationId.equals("facebook")) {
                OAuth2AuthorizedClient client =
                    clientService.loadAuthorizedClient(clientRegistrationId, oauthToken.getName());
                accessToken = client.getAccessToken().getTokenValue();

                LOG.error(accessToken);
            }
        }
        return new Facebook(accessToken);
    }

}

然后按照本教程 from one of Spring oauth2 developers 进行操作，它帮助我将获取 Facebook token 集成到我的项目中。
