我想使用spring security oidc自定义oauth2client的状态参数。我用的是Spring。问题是我无法在客户端注册中添加自定义状态。下面是我的安全配置。

@Bean
    SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        return http
                .authorizeExchange()
                .pathMatchers("/","/jwt").permitAll()
                .anyExchange().authenticated().and()
                .oauth2Client()
                .build();
    }

@Bean
    public ReactiveClientRegistrationRepository reactiveClientRegistrationRepository(RegisteredClients clients) {
        List<ClientRegistration> clientRegistrations = clients.getClients()
                .entrySet().stream()
                .map(clientRegistration -> {
                    String registrationId = clientRegistration.getKey();
                    RegisteredClients.OAuthClient client = clientRegistration.getValue();

                    return ClientRegistration.withRegistrationId(registrationId)
                            .clientId(client.getClientId())
                            .clientSecret(client.getClientSecret())
                            .redirectUriTemplate(client.getRedirectUri())
                            .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                            .tokenUri(client.getTokenUri())
                            .authorizationUri(client.getAuthorizationUri())
                            .scope("openid")
                            .build();
                })
                .collect(toList());
        return new InMemoryReactiveClientRegistrationRepository(clientRegistrations);
    }
