OAuth 2.0 客户端

OAuth 2.0 客户端特性提供了对OAuth 2.0 授权框架中定义的客户端角色的支持。

概括来说，核心特性包括：

授权许可类型支持

客户端认证支持

JWT 不记名令牌

HTTP 客户端支持（用于请求受保护资源）

`HttpSecurity.oauth2Client()` DSL 提供了一系列配置选项，用于自定义 OAuth 2.0 客户端使用的核心组件。此外，`HttpSecurity.oauth2Client().authorizationCodeGrant()` 启用了对授权码许可类型的自定义。

以下代码展示了 `HttpSecurity.oauth2Client()` DSL 提供的完整配置选项：

OAuth2 客户端配置选项

Java
Kotlin

@Configuration
@EnableWebSecurity
public class OAuth2ClientSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			.oauth2Client(oauth2 -> oauth2
				.clientRegistrationRepository(this.clientRegistrationRepository())
				.authorizedClientRepository(this.authorizedClientRepository())
				.authorizedClientService(this.authorizedClientService())
				.authorizationCodeGrant(codeGrant -> codeGrant
					.authorizationRequestRepository(this.authorizationRequestRepository())
					.authorizationRequestResolver(this.authorizationRequestResolver())
					.accessTokenResponseClient(this.accessTokenResponseClient())
				)
			);
		return http.build();
	}
}

@Configuration
@EnableWebSecurity
class OAuth2ClientSecurityConfig {

    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            oauth2Client {
                clientRegistrationRepository = clientRegistrationRepository()
                authorizedClientRepository = authorizedClientRepository()
                authorizedClientService = authorizedClientService()
                authorizationCodeGrant {
                    authorizationRequestRepository = authorizationRequestRepository()
                    authorizationRequestResolver = authorizationRequestResolver()
                    accessTokenResponseClient = accessTokenResponseClient()
                }
            }
        }
        return http.build()
    }
}

除了 `HttpSecurity.oauth2Client()` DSL 外，还支持 XML 配置。

以下代码展示了security 命名空间中可用的完整配置选项：

OAuth2 客户端 XML 配置选项

<http>
	<oauth2-client client-registration-repository-ref="clientRegistrationRepository"
				   authorized-client-repository-ref="authorizedClientRepository"
				   authorized-client-service-ref="authorizedClientService">
		<authorization-code-grant
				authorization-request-repository-ref="authorizationRequestRepository"
				authorization-request-resolver-ref="authorizationRequestResolver"
				access-token-response-client-ref="accessTokenResponseClient"/>
	</oauth2-client>
</http>

`OAuth2AuthorizedClientManager` 负责管理 OAuth 2.0 客户端的授权（或重新授权），并与一个或多个 `OAuth2AuthorizedClientProvider` 协同工作。

以下代码展示了如何注册 `OAuth2AuthorizedClientManager` 的 `@Bean` 示例，并将其与支持 `authorization_code`、`refresh_token`、`client_credentials` 和 `password` 授权许可类型的 `OAuth2AuthorizedClientProvider` 组合关联起来：

Java
Kotlin

@Bean
public OAuth2AuthorizedClientManager authorizedClientManager(
		ClientRegistrationRepository clientRegistrationRepository,
		OAuth2AuthorizedClientRepository authorizedClientRepository) {

	OAuth2AuthorizedClientProvider authorizedClientProvider =
			OAuth2AuthorizedClientProviderBuilder.builder()
					.authorizationCode()
					.refreshToken()
					.clientCredentials()
					.password()
					.build();

	DefaultOAuth2AuthorizedClientManager authorizedClientManager =
			new DefaultOAuth2AuthorizedClientManager(
					clientRegistrationRepository, authorizedClientRepository);
	authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);

	return authorizedClientManager;
}

@Bean
fun authorizedClientManager(
        clientRegistrationRepository: ClientRegistrationRepository,
        authorizedClientRepository: OAuth2AuthorizedClientRepository): OAuth2AuthorizedClientManager {
    val authorizedClientProvider: OAuth2AuthorizedClientProvider = OAuth2AuthorizedClientProviderBuilder.builder()
            .authorizationCode()
            .refreshToken()
            .clientCredentials()
            .password()
            .build()
    val authorizedClientManager = DefaultOAuth2AuthorizedClientManager(
            clientRegistrationRepository, authorizedClientRepository)
    authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider)
    return authorizedClientManager
}
