OAuth 2.0 客户端功能为 OAuth 2.0 授权框架中定义的客户端角色提供支持。Spring中文文档

概括地说，可用的核心功能包括：Spring中文文档

授权授权支持
客户端身份验证支持
HTTP 客户端支持

DSL 提供了许多配置选项，用于自定义 OAuth 2.0 客户端使用的核心组件。ServerHttpSecurity.oauth2Client()Spring中文文档

以下代码显示了 DSL 提供的完整配置选项：ServerHttpSecurity.oauth2Client()Spring中文文档

OAuth2 客户端配置选项
@Configuration
@EnableWebFluxSecurity
public class OAuth2ClientSecurityConfig {

	@Bean
	public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
		http
			.oauth2Client(oauth2 -> oauth2
				.clientRegistrationRepository(this.clientRegistrationRepository())
				.authorizedClientRepository(this.authorizedClientRepository())
				.authorizationRequestRepository(this.authorizationRequestRepository())
				.authorizationRequestResolver(this.authorizationRequestResolver())
				.authenticationConverter(this.authenticationConverter())
				.authenticationManager(this.authenticationManager())
			);

		return http.build();
	}
}
@Configuration
@EnableWebFluxSecurity
class OAuth2ClientSecurityConfig {

    @Bean
    fun securityFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain {
        http {
            oauth2Client {
                clientRegistrationRepository = clientRegistrationRepository()
                authorizedClientRepository = authorizedClientRepository()
                authorizationRequestRepository = authorizedRequestRepository()
                authorizationRequestResolver = authorizationRequestResolver()
                authenticationConverter = authenticationConverter()
                authenticationManager = authenticationManager()
            }
        }

        return http.build()
    }
}

负责与一个或多个 OAuth 2.0 客户端协作管理 OAuth 2.0 客户端的授权（或重新授权）。ReactiveOAuth2AuthorizedClientManagerReactiveOAuth2AuthorizedClientProviderSpring中文文档

下面的代码演示如何注册一个组合并将其与提供支持的复合体相关联的示例：ReactiveOAuth2AuthorizedClientManager@BeanReactiveOAuth2AuthorizedClientProviderauthorization_coderefresh_tokenclient_credentialspasswordSpring中文文档

@Bean
public ReactiveOAuth2AuthorizedClientManager authorizedClientManager(
		ReactiveClientRegistrationRepository clientRegistrationRepository,
		ServerOAuth2AuthorizedClientRepository authorizedClientRepository) {

	ReactiveOAuth2AuthorizedClientProvider authorizedClientProvider =
			ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
					.authorizationCode()
					.refreshToken()
					.clientCredentials()
					.password()
					.build();

	DefaultReactiveOAuth2AuthorizedClientManager authorizedClientManager =
			new DefaultReactiveOAuth2AuthorizedClientManager(
					clientRegistrationRepository, authorizedClientRepository);
	authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);

	return authorizedClientManager;
}
@Bean
fun authorizedClientManager(
        clientRegistrationRepository: ReactiveClientRegistrationRepository,
        authorizedClientRepository: ServerOAuth2AuthorizedClientRepository): ReactiveOAuth2AuthorizedClientManager {
    val authorizedClientProvider: ReactiveOAuth2AuthorizedClientProvider = ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
            .authorizationCode()
            .refreshToken()
            .clientCredentials()

            .build()
    val authorizedClientManager = DefaultReactiveOAuth2AuthorizedClientManager(
            clientRegistrationRepository, authorizedClientRepository)
    authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider)
    return authorizedClientManager
}
