Spring Security 5在Application Runner中调用OAuth2 SecuredAPI会导致IllegalArgumentException

spring-boot

给定以下代码,是否可以在应用程序运行程序中调用受客户端凭据保护的API?

@Bean
public ApplicationRunner test(
    WebClient.Builder builder,
    ClientRegistrationRepository clientRegistrationRepo, 
    OAuth2AuthorizedClientRepository authorizedClient) {
        return args -> {
            try {
                var oauth2 =
                    new ServletOAuth2AuthorizedClientExchangeFilterFunction(
                        clientRegistrationRepo,
                        authorizedClient);
                oauth2.setDefaultClientRegistrationId("test");
                var response = builder
                    .apply(oauth2.oauth2Configuration())
                    .build()
                    .get()
                    .uri("test")
                    .retrieve()
                    .bodyToMono(String.class)
                    .block();
                log.info("Response - {}", response);
            } catch (Exception e) {
                log.error("Failed to call test.", e);
            }
        };
    }

该代码由于以下原因而失败:

java.lang.IllegalArgumentException: request cannot be null

全栈,

java.lang.IllegalArgumentException: request cannot be null
    at org.springframework.util.Assert.notNull(Assert.java:198) ~[spring-core-5.1.5.RELEASE.jar:5.1.5.RELEASE]
    at org.springframework.security.oauth2.client.web.HttpSessionOAuth2AuthorizedClientRepository.loadAuthorizedClient(HttpSessionOAuth2AuthorizedClientRepository.java:47) ~[spring-security-oauth2-client-5.1.4.RELEASE.jar:5.1.4.RELEASE]

    at org.springframework.security.oauth2.client.web.reactive.function.client.ServletOAuth2AuthorizedClientExchangeFilterFunction.lambda$null$2(ServletOAuth2AuthorizedClientExchangeFilterFunction.java:209) ~[spring-security-oauth2-client-5.1.4.RELEASE.jar:5.1.4.RELEASE]
    at org.springframework.web.reactive.function.client.DefaultWebClient$DefaultRequestBodyUriSpec.attributes(DefaultWebClient.java:234) ~[spring-webflux-5.1.5.RELEASE.jar:5.1.5.RELEASE]
    at org.springframework.web.reactive.function.client.DefaultWebClient$DefaultRequestBodyUriSpec.attributes(DefaultWebClient.java:153) ~[spring-webflux-5.1.5.RELEASE.jar:5.1.5.RELEASE]

失败的方法看起来像

public <T extends OAuth2AuthorizedClient> T loadAuthorizedClient(
    String clientRegistrationId,  Authentication principal, HttpServletRequest request){

    Assert.hasText(clientRegistrationId, "clientRegistrationId cannot be empty");
    Assert.notNull(request, "request cannot be null");
    return (OAuth2AuthorizedClient)this
        .getAuthorizedClients(request)
        .get(clientRegistrationId);
}

这是有道理的,因为它不需要HttpServletRequest使用,它在应用程序启动时被调用。

除了我自己禁止操作外,还有其他解决方法OAuth2AuthorizedClientRepository吗?

//编辑,

这不是完全反应堆。它是一个Spring Web堆栈,其中使用了WebClient。

我很清楚ServerOAuth2AuthorizedClientExchangeFilterFunction哪个适用于完全响应式堆栈,ReactiveClientRegistrationRepositoryReactiveOauth2AuthorizedClient哪些要求不适用,由于基于Servlet堆栈而不是响应式的应用程序中的要求,它们不可用。

由于我也偶然发现了这个问题,因此我将详细介绍DarrenForsythe的最新答案,以使其他人更容易找到:

OP提交的问题导致该问题的实施OAuth2AuthorizedClientManager能够

在HttpServletRequest上下文之外运行,例如在计划的/后台线程中和/或在服务层中

来自官方文档

所述实现AuthorizedClientServiceOAuth2AuthorizedClientManager传递给,ServletOAuth2AuthorizedClientExchangeFilterFunction以替换默认的实现。

在我的示例中,这看起来像这样:

@Bean
public OAuth2AuthorizedClientManager authorizedClientManager(
        ClientRegistrationRepository clientRegistrationRepository,
        OAuth2AuthorizedClientService clientService)
{

    OAuth2AuthorizedClientProvider authorizedClientProvider = 
        OAuth2AuthorizedClientProviderBuilder.builder()
            .clientCredentials()
            .build();

    AuthorizedClientServiceOAuth2AuthorizedClientManager authorizedClientManager = 
        new AuthorizedClientServiceOAuth2AuthorizedClientManager(
            clientRegistrationRepository, clientService);
    authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);

    return authorizedClientManager;
}

@Bean
WebClient webClient(OAuth2AuthorizedClientManager authorizedClientManager)
{
    ServletOAuth2AuthorizedClientExchangeFilterFunction oauth2 =
        new ServletOAuth2AuthorizedClientExchangeFilterFunction(
            authorizedClientManager);
    oauth2.setDefaultClientRegistrationId("keycloak");
    return WebClient.builder().apply(oauth2.oauth2Configuration()).build();
}
