Spring Security WebFlux IP 白名单

Question

在利用 WebFlux 的最新 Spring Security 中，安全配置的工作方式如下：

\n\n

SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {\nhttp.authorizeExchange().pathMatchers("/**") ....\n

\n\n

之前有一个方法 hasIpAddress("xxx.xxx.xxx.xxx") 可以用来配置IP白名单，现在没有了。

\n\n

如何为新的Spring Security Webflux指定IP白名单？

\n\n

基于下面@\xc3\xb6zkan pakdil 的想法，这是我的代码，但 IP 过滤器不起作用 - 来自不在白名单上的 IP 的请求仍然可以通过。

\n\n

private Mono<AuthorizationDecision> isAuthorizedIP(Mono<Authentication> authentication, AuthorizationContext context) {\n    String ip = context.getExchange().getRequest().getRemoteAddress().getAddress().toString().replace("/", "");\n\n    return authentication.map((a) -> new AuthorizationDecision(\n                                        ipWhiteList.contains(ip)));     \n}\n

\n\n

SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) 抛出异常 {

\n\n

http.authorizeExchange().anyExchange().access(this::isAuthorizedIP).and().oauth2Login();

\n\n

返回 http.build();

\n\n

}

\n

我花了一段时间才弄清楚，但最终，我找到了一种可行的方法。请检查https://github.com/ozkanpakdil/spring-examples/tree/master/webflux-ip-whitelist并告诉我这是否没有帮助。

只需像这样定义 WebSecurityConfig

import org.springframework.context.annotation.Bean;
import org.springframework.security.authorization.AuthorizationDecision;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.server.SecurityWebFilterChain;
import org.springframework.security.web.server.authorization.AuthorizationContext;
import reactor.core.publisher.Mono;

import java.util.ArrayList;

@EnableWebFluxSecurity
public class WebSecurityConfig {

    ArrayList<String> whiteListIp = new ArrayList();

    public WebSecurityConfig() {
        whiteListIp.add("0:0:0:0:0:0:0:1");
        whiteListIp.add("192.168.1.1");
        whiteListIp.add("127.0.0.1");
    }

    @Bean
    public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        http
                .authorizeExchange()
                .anyExchange()
                .access(this::whiteListIp)
                .and()
                .httpBasic();

        return http.build();
    }

    private Mono<AuthorizationDecision> whiteListIp(Mono<Authentication> authentication, AuthorizationContext context) {
        String ip = context.getExchange().getRequest().getRemoteAddress().getAddress().toString().replace("/", "");
        return authentication.map((a) -> new AuthorizationDecision(a.isAuthenticated()))
                .defaultIfEmpty(new AuthorizationDecision(
                        (whiteListIp.contains(ip)) ? true : false
                ));
    }

}

并将您的 IP 列入白名单。
