授权客户端功能

本节介绍了 Spring Security for OAuth2 客户端提供的其他功能。spring-doc.cadn.net.cn

解析授权客户端

这@RegisteredOAuth2AuthorizedClientannotation 提供了将 method 参数解析为 type 为 argument 值的功能OAuth2AuthorizedClient. 与访问OAuth2AuthorizedClient通过使用OAuth2AuthorizedClientManager或OAuth2AuthorizedClientService. 以下示例演示如何使用@RegisteredOAuth2AuthorizedClient:spring-doc.cadn.net.cn

@Controller
public class OAuth2ClientController {

	@GetMapping("/")
	public String index(@RegisteredOAuth2AuthorizedClient("okta") OAuth2AuthorizedClient authorizedClient) {
		OAuth2AccessToken accessToken = authorizedClient.getAccessToken();

		...

		return "index";
	}
}
@Controller
class OAuth2ClientController {
    @GetMapping("/")
    fun index(@RegisteredOAuth2AuthorizedClient("okta") authorizedClient: OAuth2AuthorizedClient): String {
        val accessToken = authorizedClient.accessToken

        ...

        return "index"
    }
}

这@RegisteredOAuth2AuthorizedClientannotation 由OAuth2AuthorizedClientArgumentResolver，它直接使用OAuth2AuthorizedClientManager因此，继承了它的能力。spring-doc.cadn.net.cn

RestClient 集成

支持RestClient由OAuth2ClientHttpRequestInterceptor. 此侦听器提供了通过放置Bearertoken 中Authorization标头。 拦截器直接使用OAuth2AuthorizedClientManager因此继承了以下功能：spring-doc.cadn.net.cn

以下示例使用默认的OAuth2AuthorizedClientManager要配置RestClient能够通过以下方式访问受保护的资源Bearer令牌Authorization标头：spring-doc.cadn.net.cn

配置RestClient跟ClientHttpRequestInterceptor
@Configuration
public class RestClientConfig {

	@Bean
	public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager) {
		OAuth2ClientHttpRequestInterceptor requestInterceptor =
				new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);

		return RestClient.builder()
				.requestInterceptor(requestInterceptor)
				.build();
	}

}
@Configuration
class RestClientConfig {

	@Bean
	fun restClient(authorizedClientManager: OAuth2AuthorizedClientManager): RestClient {
		val requestInterceptor = OAuth2ClientHttpRequestInterceptor(authorizedClientManager)

		return RestClient.builder()
			.requestInterceptor(requestInterceptor)
			.build()
	}

}

提供clientRegistrationId

OAuth2ClientHttpRequestInterceptor使用ClientRegistrationIdResolver确定使用哪个客户端获取 Access Token。 默认情况下，RequestAttributeClientRegistrationIdResolver用于解析clientRegistrationId从HttpRequest#attributes().spring-doc.cadn.net.cn

以下示例演示如何提供clientRegistrationIdvia 属性：spring-doc.cadn.net.cn

提供clientRegistrationIdvia 属性
import static org.springframework.security.oauth2.client.web.client.RequestAttributeClientRegistrationIdResolver.clientRegistrationId;

@Controller
public class ResourceController {

	private final RestClient restClient;

	public ResourceController(RestClient restClient) {
		this.restClient = restClient;
	}

	@GetMapping("/")
	public String index() {
		String resourceUri = "...";

		String body = this.restClient.get()
				.uri(resourceUri)
				.attributes(clientRegistrationId("okta"))   (1)
				.retrieve()
				.body(String.class);

		// ...

		return "index";
	}

}
import org.springframework.security.oauth2.client.web.client.RequestAttributeClientRegistrationIdResolver.clientRegistrationId
import org.springframework.web.client.body

@Controller
class ResourceController(private restClient: RestClient) {

	@GetMapping("/")
	fun index(): String {
		val resourceUri = "..."

		val body: String = restClient.get()
				.uri(resourceUri)
				.attributes(clientRegistrationId("okta"))   (1)
				.retrieve()
				.body<String>()

		// ...

		return "index"
	}

}
1 clientRegistrationId()是一个staticmethod 中RequestAttributeClientRegistrationIdResolver.

或者，自定义ClientRegistrationIdResolver可以提供。 以下示例配置了一个自定义实现，该实现将clientRegistrationId来自当前用户。spring-doc.cadn.net.cn

配置ClientHttpRequestInterceptor带自定义ClientRegistrationIdResolver
@Configuration
public class RestClientConfig {

	@Bean
	public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager) {
		OAuth2ClientHttpRequestInterceptor requestInterceptor =
				new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);
		requestInterceptor.setClientRegistrationIdResolver(clientRegistrationIdResolver());

		return RestClient.builder()
				.requestInterceptor(requestInterceptor)
				.build();
	}

	private static ClientRegistrationIdResolver clientRegistrationIdResolver() {
		return (request) -> {
			Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
			return (authentication instanceof OAuth2AuthenticationToken principal)
					? principal.getAuthorizedClientRegistrationId() : null;
		};
	}

}
@Configuration
class RestClientConfig {

	@Bean
	fun restClient(authorizedClientManager: OAuth2AuthorizedClientManager): RestClient {
		val requestInterceptor = OAuth2ClientHttpRequestInterceptor(authorizedClientManager)
		requestInterceptor.setClientRegistrationIdResolver(clientRegistrationIdResolver())

		return RestClient.builder()
			.requestInterceptor(requestInterceptor)
			.build()
	}

	fun clientRegistrationIdResolver(): ClientRegistrationIdResolver {
		return ClientRegistrationIdResolver { request ->
			val authentication = SecurityContextHolder.getContext().getAuthentication()
			return if (authentication instanceof OAuth2AuthenticationToken) {
				authentication.getAuthorizedClientRegistrationId()
			} else {
                null
			}
		}
	}

}

提供principal

OAuth2ClientHttpRequestInterceptor使用PrincipalResolver确定哪个主体名称与访问令牌相关联，这允许应用程序选择如何限定OAuth2AuthorizedClient即存储。 默认情况下，SecurityContextHolderPrincipalResolver用于解析电流principal从SecurityContextHolder.spring-doc.cadn.net.cn

或者，principal可以从HttpRequest#attributes()通过配置RequestAttributePrincipalResolver，如下例所示：spring-doc.cadn.net.cn

配置ClientHttpRequestInterceptor跟RequestAttributePrincipalResolver
@Configuration
public class RestClientConfig {

	@Bean
	public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager) {
		OAuth2ClientHttpRequestInterceptor requestInterceptor =
				new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);
		requestInterceptor.setPrincipalResolver(new RequestAttributePrincipalResolver());

		return RestClient.builder()
				.requestInterceptor(requestInterceptor)
				.build();
	}

}
@Configuration
class RestClientConfig {

	@Bean
	fun restClient(authorizedClientManager: OAuth2AuthorizedClientManager): RestClient {
		val requestInterceptor = OAuth2ClientHttpRequestInterceptor(authorizedClientManager)
		requestInterceptor.setPrincipalResolver(RequestAttributePrincipalResolver())

		return RestClient.builder()
			.requestInterceptor(requestInterceptor)
			.build()
	}

}

以下示例演示如何提供principalname 通过属性将OAuth2AuthorizedClient添加到应用程序而不是当前用户：spring-doc.cadn.net.cn

提供principalname 通过 attributes
import static org.springframework.security.oauth2.client.web.client.RequestAttributeClientRegistrationIdResolver.clientRegistrationId;
import static org.springframework.security.oauth2.client.web.client.RequestAttributePrincipalResolver.principal;

@Controller
public class ResourceController {

	private final RestClient restClient;

	public ResourceController(RestClient restClient) {
		this.restClient = restClient;
	}

	@GetMapping("/")
	public String index() {
		String resourceUri = "...";

		String body = this.restClient.get()
				.uri(resourceUri)
				.attributes(clientRegistrationId("okta"))
				.attributes(principal("my-application"))   (1)
				.retrieve()
				.body(String.class);

		// ...

		return "index";
	}

}
import org.springframework.security.oauth2.client.web.client.RequestAttributeClientRegistrationIdResolver.clientRegistrationId
import org.springframework.security.oauth2.client.web.client.RequestAttributePrincipalResolver.principal
import org.springframework.web.client.body

@Controller
class ResourceController(private restClient: RestClient) {

    @GetMapping("/")
	fun index(): String {
		val resourceUri = "..."

		val body: String = restClient.get()
				.uri(resourceUri)
				.attributes(clientRegistrationId("okta"))
				.attributes(principal("my-application"))   (1)
				.retrieve()
				.body<String>()

		// ...

		return "index"
	}

}
1 principal()是一个staticmethod 中RequestAttributePrincipalResolver.

处理失败

如果访问令牌因任何原因无效（例如令牌过期），则通过删除访问令牌来处理失败可能是有益的，这样它就不能再次使用。 您可以通过提供OAuth2AuthorizationFailureHandler以删除 Access Token。spring-doc.cadn.net.cn

以下示例使用OAuth2AuthorizedClientRepository要设置OAuth2AuthorizationFailureHandler这会删除无效的OAuth2AuthorizedClient 在HttpServletRequest:spring-doc.cadn.net.cn

配置OAuth2AuthorizationFailureHandler用OAuth2AuthorizedClientRepository
@Configuration
public class RestClientConfig {

	@Bean
	public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager,
			OAuth2AuthorizedClientRepository authorizedClientRepository) {

		OAuth2ClientHttpRequestInterceptor requestInterceptor =
				new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);

		OAuth2AuthorizationFailureHandler authorizationFailureHandler =
			OAuth2ClientHttpRequestInterceptor.authorizationFailureHandler(authorizedClientRepository);
		requestInterceptor.setAuthorizationFailureHandler(authorizationFailureHandler);

		return RestClient.builder()
				.requestInterceptor(requestInterceptor)
				.build();
	}

}
@Configuration
class RestClientConfig {

	@Bean
	fun restClient(authorizedClientManager: OAuth2AuthorizedClientManager,
			authorizedClientRepository: OAuth2AuthorizedClientRepository): RestClient {

		val requestInterceptor = OAuth2ClientHttpRequestInterceptor(authorizedClientManager)

		val authorizationFailureHandler = OAuth2ClientHttpRequestInterceptor
			.authorizationFailureHandler(authorizedClientRepository)
		requestInterceptor.setAuthorizationFailureHandler(authorizationFailureHandler)

		return RestClient.builder()
			.requestInterceptor(requestInterceptor)
			.build()
	}

}

或者，一个OAuth2AuthorizedClientService可用于删除无效的OAuth2AuthorizedClient 在HttpServletRequest，如下例所示：spring-doc.cadn.net.cn

配置OAuth2AuthorizationFailureHandler用OAuth2AuthorizedClientService
@Configuration
public class RestClientConfig {

	@Bean
	public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager,
			OAuth2AuthorizedClientService authorizedClientService) {

		OAuth2ClientHttpRequestInterceptor requestInterceptor =
				new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);

		OAuth2AuthorizationFailureHandler authorizationFailureHandler =
			OAuth2ClientHttpRequestInterceptor.authorizationFailureHandler(authorizedClientService);
		requestInterceptor.setAuthorizationFailureHandler(authorizationFailureHandler);

		return RestClient.builder()
				.requestInterceptor(requestInterceptor)
				.build();
	}

}
@Configuration
class RestClientConfig {

	@Bean
	fun restClient(authorizedClientManager: OAuth2AuthorizedClientManager,
			authorizedClientService: OAuth2AuthorizedClientService): RestClient {

		val requestInterceptor = OAuth2ClientHttpRequestInterceptor(authorizedClientManager)

		val authorizationFailureHandler = OAuth2ClientHttpRequestInterceptor
			.authorizationFailureHandler(authorizedClientService)
		requestInterceptor.setAuthorizationFailureHandler(authorizationFailureHandler)

		return RestClient.builder()
			.requestInterceptor(requestInterceptor)
			.build()
	}

}

用于 Servlet 环境的 WebClient 集成

OAuth 2.0 客户端支持与WebClient通过使用ExchangeFilterFunction.spring-doc.cadn.net.cn

这ServletOAuth2AuthorizedClientExchangeFilterFunction提供了一种使用OAuth2AuthorizedClient并包括关联的OAuth2AccessToken作为 Bearer Token 进行验证。 它直接使用OAuth2AuthorizedClientManager因此，继承了以下功能：spring-doc.cadn.net.cn

以下代码显示了如何配置WebClient使用 OAuth 2.0 客户端支持：spring-doc.cadn.net.cn

@Bean
WebClient webClient(OAuth2AuthorizedClientManager authorizedClientManager) {
	ServletOAuth2AuthorizedClientExchangeFilterFunction oauth2Client =
			new ServletOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager);
	return WebClient.builder()
			.apply(oauth2Client.oauth2Configuration())
			.build();
}
@Bean
fun webClient(authorizedClientManager: OAuth2AuthorizedClientManager?): WebClient {
    val oauth2Client = ServletOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager)
    return WebClient.builder()
            .apply(oauth2Client.oauth2Configuration())
            .build()
}

提供授权客户

这ServletOAuth2AuthorizedClientExchangeFilterFunction通过解析OAuth2AuthorizedClient从ClientRequest.attributes()（请求属性）。spring-doc.cadn.net.cn

以下代码演示如何设置OAuth2AuthorizedClient作为请求属性：spring-doc.cadn.net.cn

@GetMapping("/")
public String index(@RegisteredOAuth2AuthorizedClient("okta") OAuth2AuthorizedClient authorizedClient) {
	String resourceUri = ...

	String body = webClient
			.get()
			.uri(resourceUri)
			.attributes(oauth2AuthorizedClient(authorizedClient))   (1)
			.retrieve()
			.bodyToMono(String.class)
			.block();

	...

	return "index";
}
@GetMapping("/")
fun index(@RegisteredOAuth2AuthorizedClient("okta") authorizedClient: OAuth2AuthorizedClient): String {
    val resourceUri: String = ...
    val body: String = webClient
            .get()
            .uri(resourceUri)
            .attributes(oauth2AuthorizedClient(authorizedClient)) (1)
            .retrieve()
            .bodyToMono()
            .block()

    ...

    return "index"
}
1 oauth2AuthorizedClient()是一个staticmethod 中ServletOAuth2AuthorizedClientExchangeFilterFunction.

以下代码演示如何设置ClientRegistration.getRegistrationId()作为请求属性：spring-doc.cadn.net.cn

@GetMapping("/")
public String index() {
	String resourceUri = ...

	String body = webClient
			.get()
			.uri(resourceUri)
			.attributes(clientRegistrationId("okta"))   (1)
			.retrieve()
			.bodyToMono(String.class)
			.block();

	...

	return "index";
}
@GetMapping("/")
fun index(): String {
    val resourceUri: String = ...

    val body: String = webClient
            .get()
            .uri(resourceUri)
            .attributes(clientRegistrationId("okta"))  (1)
            .retrieve()
            .bodyToMono()
            .block()

    ...

    return "index"
}
1 clientRegistrationId()是一个staticmethod 中ServletOAuth2AuthorizedClientExchangeFilterFunction.

以下代码演示如何设置Authentication作为请求属性：spring-doc.cadn.net.cn

@GetMapping("/")
public String index() {
	String resourceUri = ...

	Authentication anonymousAuthentication = new AnonymousAuthenticationToken(
			"anonymous", "anonymousUser", AuthorityUtils.createAuthorityList("ROLE_ANONYMOUS"));
	String body = webClient
			.get()
			.uri(resourceUri)
			.attributes(authentication(anonymousAuthentication))   (1)
			.retrieve()
			.bodyToMono(String.class)
			.block();

	...

	return "index";
}
@GetMapping("/")
fun index(): String {
    val resourceUri: String = ...

    val anonymousAuthentication: Authentication = AnonymousAuthenticationToken(
            "anonymous", "anonymousUser", AuthorityUtils.createAuthorityList("ROLE_ANONYMOUS"))
    val body: String = webClient
            .get()
            .uri(resourceUri)
            .attributes(authentication(anonymousAuthentication))  (1)
            .retrieve()
            .bodyToMono()
            .block()

    ...

    return "index"
}
1 authentication()是一个staticmethod 中ServletOAuth2AuthorizedClientExchangeFilterFunction.

建议谨慎使用此功能，因为所有 HTTP 请求都将收到绑定到提供的委托人的访问令牌。spring-doc.cadn.net.cn

默认授权客户端

如果两者都不是OAuth2AuthorizedClient或ClientRegistration.getRegistrationId()作为请求属性提供，ServletOAuth2AuthorizedClientExchangeFilterFunction可以确定要使用的默认客户端，具体取决于其配置。spring-doc.cadn.net.cn

如果setDefaultOAuth2AuthorizedClient(true)，并且用户已使用HttpSecurity.oauth2Login()这OAuth2AccessToken与当前OAuth2AuthenticationToken被使用。spring-doc.cadn.net.cn

以下代码显示了具体配置：spring-doc.cadn.net.cn

@Bean
WebClient webClient(OAuth2AuthorizedClientManager authorizedClientManager) {
	ServletOAuth2AuthorizedClientExchangeFilterFunction oauth2Client =
			new ServletOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager);
	oauth2Client.setDefaultOAuth2AuthorizedClient(true);
	return WebClient.builder()
			.apply(oauth2Client.oauth2Configuration())
			.build();
}
@Bean
fun webClient(authorizedClientManager: OAuth2AuthorizedClientManager?): WebClient {
    val oauth2Client = ServletOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager)
    oauth2Client.setDefaultOAuth2AuthorizedClient(true)
    return WebClient.builder()
            .apply(oauth2Client.oauth2Configuration())
            .build()
}

请谨慎使用此功能，因为所有 HTTP 请求都会收到访问令牌。spring-doc.cadn.net.cn

或者，如果setDefaultClientRegistrationId("okta")配置了有效的ClientRegistration这OAuth2AccessToken与OAuth2AuthorizedClient被使用。spring-doc.cadn.net.cn

以下代码显示了具体配置：spring-doc.cadn.net.cn

@Bean
WebClient webClient(OAuth2AuthorizedClientManager authorizedClientManager) {
	ServletOAuth2AuthorizedClientExchangeFilterFunction oauth2Client =
			new ServletOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager);
	oauth2Client.setDefaultClientRegistrationId("okta");
	return WebClient.builder()
			.apply(oauth2Client.oauth2Configuration())
			.build();
}
@Bean
fun webClient(authorizedClientManager: OAuth2AuthorizedClientManager?): WebClient {
    val oauth2Client = ServletOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager)
    oauth2Client.setDefaultClientRegistrationId("okta")
    return WebClient.builder()
            .apply(oauth2Client.oauth2Configuration())
            .build()
}

请谨慎使用此功能，因为所有 HTTP 请求都会收到访问令牌。spring-doc.cadn.net.cn
