我正在尝试通过webclient以下设置获取承载令牌，以对Servlet应用程序中的受保护资源服务器进行集成测试。

spring:
  security:
    oauth2:
      client:
        registration:
          idp:
            clientId: id
            clientSecret: secret
            authorization-grant-type: client_credentials
            scope: read
        provider:
          idp:
            authorization-uri: myidp/authorization.oauth2
            token-uri: myidp/token.oauth2
            user-info-uri: myidp/userinfo.openid
            user-name-attribute: name

还有豆子

    @Bean
    WebClient webClient(ClientRegistrationRepository clientRegistrations,
            OAuth2AuthorizedClientRepository authorizedClients) {
        ServletOAuth2AuthorizedClientExchangeFilterFunction oauth = new ServletOAuth2AuthorizedClientExchangeFilterFunction(
                clientRegistrations, authorizedClients);
        // (optional) explicitly opt into using the oauth2Login to provide an access token implicitly
        // oauth.setDefaultOAuth2AuthorizedClient(true);
        // (optional) set a default ClientRegistration.registrationId
        // oauth.setDefaultClientRegistrationId("client-registration-id");
        return WebClient.builder().apply(oauth.oauth2Configuration()).build();
    }

并自动将Web客户端连接到测试，然后像这样调用它，

webClient.get().uri("http://localhost:" + port + "/web/it")
                .attributes(ServletOAuth2AuthorizedClientExchangeFilterFunction.clientRegistrationId("idp")).retrieve()
                .bodyToMono(String.class).block();

我假设交换功能将获取访问令牌（如果可用），或者进行调用以从IDP获取新令牌。但是，它将始终失败，HttpSessionOAuth2AuthorizedClientRepository因为the
HttpServletRequest为null。

在总体测试看起来像这样的情况下，它可以自动配置为IDP提供程序配置一些bean。

@SpringBootTest(classes = WebITApplication.class,
        webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ExtendWith(SpringExtension.class)
@ActiveProfiles("web-it")
class WebJwtIt {

    @LocalServerPort
    private int port;

    @Autowired
    private WebClient webClient;

    @Test
    void testIdpJwt() {

        String response = webClient.get().uri("http://localhost:" + port + "/web/it")
                .attributes(ServletOAuth2AuthorizedClientExchangeFilterFunction.clientRegistrationId("ping")).retrieve()
                .bodyToMono(String.class).block();
        assertThat(response).isEqualTo("pass");
    }

    @RestController
    @SpringBootApplication
    @ImportAutoConfiguration(IdpAutoConfiguration.class)
    static class WebITApplication implements IdpSecurityAdapter {

              @Bean
    WebClient webClient(ClientRegistrationRepository clientRegistrations,
            OAuth2AuthorizedClientRepository authorizedClients) {
        ServletOAuth2AuthorizedClientExchangeFilterFunction oauth = new ServletOAuth2AuthorizedClientExchangeFilterFunction(
                clientRegistrations, authorizedClients);
        // (optional) explicitly opt into using the oauth2Login to provide an access token implicitly
        // oauth.setDefaultOAuth2AuthorizedClient(true);
        // (optional) set a default ClientRegistration.registrationId
        // oauth.setDefaultClientRegistrationId("client-registration-id");
        return WebClient.builder().apply(oauth.oauth2Configuration()).build();
    }
        public static void main(String args[]) {

            new SpringApplicationBuilder().profiles("web-it").build().run(WebITApplication.class, args);
        }

        @GetMapping
        public String secured() {
            return "secured";
        }

        @GetMapping("/web/it")
        public String securedOne() {
            return "pass";
        }

        @Override
        public void configure(final HttpSecurity httpSecurity) throws IdpSecurityAdapterException {
            try {
                httpSecurity.oauth2Client();
            } catch (Exception e) {
                throw new IdpSecurityAdapterException("Failed to Configure Oauth2Client", e);
            }
        }

        @Override
        public IdpProvider getIdpProvider() {
            return IdpProvider.MyIdp;
        }
    }

无论如何，网络客户端是否可以为我获取令牌并将其添加到请求中？我知道这是可能的，spring-security- oauth:OAuthRestTemplate并且阅读我认为可以通过Web客户端实现的文档。
