OAuth2 授权端点

OAuth2AuthorizationEndpointConfigurer提供自定义 OAuth2 授权端点的功能。 它定义了扩展点，允许您自定义 OAuth2 授权请求的预处理、主处理和后处理逻辑。spring-doc.cadn.net.cn

OAuth2AuthorizationEndpointConfigurer提供以下配置选项：spring-doc.cadn.net.cn

@Bean
public SecurityFilterChain authorizationServerSecurityFilterChain(HttpSecurity http) throws Exception {
	OAuth2AuthorizationServerConfigurer authorizationServerConfigurer =
			OAuth2AuthorizationServerConfigurer.authorizationServer();

	http
		.securityMatcher(authorizationServerConfigurer.getEndpointsMatcher())
		.with(authorizationServerConfigurer, (authorizationServer) ->
			authorizationServer
				.authorizationEndpoint(authorizationEndpoint ->
					authorizationEndpoint
        				.authorizationRequestConverter(authorizationRequestConverter)   (1)
                        .authorizationRequestConverters(authorizationRequestConvertersConsumer) (2)

                        .consentPage("/oauth2/v1/authorize")    (7)
				)
		);

	return http.build();
}
1 authorizationRequestConverter()：添加AuthenticationConverter (预处理器）尝试从 中提取 OAuth2 授权请求（或同意）时使用HttpServletRequest添加到OAuth2AuthorizationCodeRequestAuthenticationToken或OAuth2AuthorizationConsentAuthenticationToken.
2 authorizationRequestConverters()：设置Consumer提供对Listof default 和 （可选） addedAuthenticationConverter允许添加、删除或自定义特定AuthenticationConverter.
3 authenticationProvider()：添加AuthenticationProvider (主处理器）用于验证OAuth2AuthorizationCodeRequestAuthenticationToken或OAuth2AuthorizationConsentAuthenticationToken.
4 authenticationProviders()：设置Consumer提供对Listof default 和 （可选） addedAuthenticationProvider允许添加、删除或自定义特定AuthenticationProvider.
5 authorizationResponseHandler()：这AuthenticationSuccessHandler (后处理器）用于处理 “authenticated”OAuth2AuthorizationCodeRequestAuthenticationToken并返回 OAuth2AuthorizationResponse。
6 errorResponseHandler()：这AuthenticationFailureHandler (后处理器）用于处理OAuth2AuthorizationCodeRequestAuthenticationException并返回 OAuth2Error 响应。
7 consentPage()：这URI，以便在授权请求流程中将资源所有者重定向到是否需要同意。

OAuth2AuthorizationEndpointConfigurer配置OAuth2AuthorizationEndpointFilter并将其注册到 OAuth2 授权服务器SecurityFilterChain @Bean.OAuth2AuthorizationEndpointFilter是Filter处理 OAuth2 授权请求（和同意）。spring-doc.cadn.net.cn

OAuth2AuthorizationEndpointFilter配置了以下默认值：spring-doc.cadn.net.cn

  • AuthenticationFailureHandler— 使用OAuth2Error与OAuth2AuthorizationCodeRequestAuthenticationException并返回OAuth2Error响应。spring-doc.cadn.net.cn

自定义授权请求验证

OAuth2AuthorizationCodeRequestAuthenticationValidator是用于验证授权码授予中使用的特定 OAuth2 授权请求参数的默认验证器。 默认实现会验证redirect_uri和scope参数。 如果验证失败，则OAuth2AuthorizationCodeRequestAuthenticationException被抛出。spring-doc.cadn.net.cn

OAuth2AuthorizationCodeRequestAuthenticationProvider通过提供Consumer<OAuth2AuthorizationCodeRequestAuthenticationContext>自setAuthenticationValidator().spring-doc.cadn.net.cn

OAuth2AuthorizationCodeRequestAuthenticationContext持有OAuth2AuthorizationCodeRequestAuthenticationToken，其中包含 OAuth2 授权请求参数。
如果验证失败，身份验证验证器必须抛出OAuth2AuthorizationCodeRequestAuthenticationException.

在开发生命周期阶段，一个常见的用例是允许localhost在redirect_uri参数。spring-doc.cadn.net.cn

DPoP 绑定访问Tokens

RFC 9449 OAuth 2.0 演示所有权证明 （DPoP） 是一种应用程序级机制，用于对访问Tokens进行发送者约束。spring-doc.cadn.net.cn

DPoP 的主要目标是防止未经授权或非法的客户端使用泄露或被盗的访问Tokens，方法是在授权服务器颁发访问Tokens时将访问Tokens绑定到公钥，并要求客户端在资源服务器上使用访问Tokens时证明拥有相应的私钥。spring-doc.cadn.net.cn

通过 DPoP 受发送方约束的访问Tokens与典型的不记名Tokens形成鲜明对比，后者可由拥有访问Tokens的任何客户端使用。spring-doc.cadn.net.cn

DPoP 引入了 DPoP 证明的概念，它是由客户端创建并作为 HTTP 请求中的标头发送的 JWT。 客户端使用 DPoP 证明来证明拥有与某个公钥对应的私钥。spring-doc.cadn.net.cn

当客户端发起访问Tokens请求时，它会在 HTTP 标头中将 DPoP 证明附加到请求。 授权服务器将访问Tokens绑定（发送者约束）到 DPoP 证明中关联的公钥。spring-doc.cadn.net.cn

当客户端发起受保护资源请求时，它会再次将 DPoP 证明附加到 HTTP 标头中的请求。spring-doc.cadn.net.cn

资源服务器直接在访问Tokens （JWT） 中或通过 OAuth2 Tokens自省端点获取有关绑定到访问Tokens的公钥的信息。 然后，资源服务器验证绑定到访问Tokens的公钥是否与 DPoP 证明中的公钥匹配。 它还验证 DPoP 证明中的访问Tokens哈希是否与请求中的访问Tokens匹配。spring-doc.cadn.net.cn

DPoP 访问Tokens请求

要请求使用 DPoP 绑定到公钥的访问Tokens，客户端必须在DPoP标头。 这适用于所有访问Tokens请求，无论授权授权类型如何（例如authorization_code,refresh_token,client_credentials等）。spring-doc.cadn.net.cn

以下 HTTP 请求显示了authorization_code访问Tokens请求，并在DPoP页眉：spring-doc.cadn.net.cn

以下代码显示了如何生成 DPoP 证明 JWT 的示例：spring-doc.cadn.net.cn

RSAKey rsaKey = ...
JWKSource<SecurityContext> jwkSource = (jwkSelector, securityContext) -> jwkSelector
		.select(new JWKSet(rsaKey));
NimbusJwtEncoder jwtEncoder = new NimbusJwtEncoder(jwkSource);

JwsHeader jwsHeader = JwsHeader.with(SignatureAlgorithm.RS256)
		.type("dpop+jwt")
		.jwk(rsaKey.toPublicJWK().toJSONObject())
		.build();
JwtClaimsSet claims = JwtClaimsSet.builder()
		.issuedAt(Instant.now())
		.claim("htm", "POST")
		.claim("htu", "https://server.example.com/oauth2/token")
		.id(UUID.randomUUID().toString())
		.build();

Jwt dPoPProof = jwtEncoder.encode(JwtEncoderParameters.from(jwsHeader, claims));

授权服务器成功验证 DPoP 证明后，DPoP 证明中的公钥将被绑定（发件人约束）到颁发的访问Tokens。spring-doc.cadn.net.cn

以下访问Tokens响应显示token_typeparameter 指定为DPoP向客户端发出信号，表明访问Tokens已绑定到其 DPoP 证明公钥：spring-doc.cadn.net.cn

HTTP/1.1 200 OK
Content-Type: application/json
Cache-Control: no-store

{
 "access_token": "Kz~8mXK1EalYznwH-LC-1fBAo.4Ljp~zsPE_NeO.gxU",
 "token_type": "DPoP",
 "expires_in": 2677
}

公钥确认

资源服务器必须能够识别访问Tokens是否受 DPoP 绑定，并验证是否绑定到 DPoP 证明的公钥。 绑定是通过以资源服务器可以访问的方式将公钥与访问Tokens相关联来实现的，例如将公钥哈希直接嵌入访问Tokens （JWT） 或通过Tokens自省。spring-doc.cadn.net.cn

当访问Tokens表示为 JWT 时，公钥哈希包含在jkt确认方法 （cnf） 声明。spring-doc.cadn.net.cn

以下示例显示了包含cnf声明中带有jktclaim，这是 DPoP 证明公钥的 JWK SHA-256 指纹：spring-doc.cadn.net.cn
