反应式 X.509 身份验证

与 Servlet X.509 身份验证类似，反应式 x509 身份验证过滤器允许从客户端提供的证书中提取身份验证令牌。spring-doc.cn

以下是反应式 x509 安全配置的示例：spring-doc.cn

Javaspring-doc.cn
Kotlinspring-doc.cn

@Bean
public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
	http
		.x509(withDefaults())
		.authorizeExchange(exchanges -> exchanges
		    .anyExchange().permitAll()
		);
	return http.build();
}

@Bean
fun securityWebFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain {
    return http {
        x509 { }
        authorizeExchange {
            authorize(anyExchange, authenticated)
        }
    }
}

在上面的配置中，当 both 和 is provided 时，将使用默认值。默认主体提取程序用于从客户提供的证书中提取 CN（公用名）字段。默认身份验证管理器执行用户帐户验证，检查具有提取的名称的用户帐户是否存在，并且该帐户未被锁定、禁用或过期。principalExtractorauthenticationManagerSubjectDnX509PrincipalExtractorReactivePreAuthenticatedAuthenticationManagerprincipalExtractorspring-doc.cn

下一个示例演示如何覆盖这些默认值。spring-doc.cn

Javaspring-doc.cn
Kotlinspring-doc.cn

@Bean
public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
	SubjectDnX509PrincipalExtractor principalExtractor =
	        new SubjectDnX509PrincipalExtractor();

	principalExtractor.setSubjectDnRegex("OU=(.*?)(?:,|$)");

	ReactiveAuthenticationManager authenticationManager = authentication -> {
		authentication.setAuthenticated("Trusted Org Unit".equals(authentication.getName()));
		return Mono.just(authentication);
	};

	http
		.x509(x509 -> x509
		    .principalExtractor(principalExtractor)
		    .authenticationManager(authenticationManager)
		)
		.authorizeExchange(exchanges -> exchanges
		    .anyExchange().authenticated()
		);
	return http.build();
}

@Bean
fun securityWebFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain? {
    val customPrincipalExtractor = SubjectDnX509PrincipalExtractor()
    customPrincipalExtractor.setSubjectDnRegex("OU=(.*?)(?:,|$)")
    val customAuthenticationManager = ReactiveAuthenticationManager { authentication: Authentication ->
        authentication.isAuthenticated = "Trusted Org Unit" == authentication.name
        Mono.just(authentication)
    }
    return http {
        x509 {
            principalExtractor = customPrincipalExtractor
            authenticationManager = customAuthenticationManager
        }
        authorizeExchange {
            authorize(anyExchange, authenticated)
        }
    }
}

在此示例中，从客户端证书的 OU 字段而不是 CN 中提取用户名，并且根本不执行账户查找。相反，如果提供的证书颁发给名为“Trusted Org Unit”的 OU，则请求将进行身份验证。ReactiveUserDetailsServicespring-doc.cn
