spring - 如何使用基本身份验证保护 Spring Cloud Eureka 服务？

问题描述

我在同一台主机上设置了多个 eureka 服务器实例。他们使用主机名 eureka-primary、secondary 和 tertiary，这些主机名在 hosts 文件中定义为 localhost 别名，并且一切正常——它们都是可见的，并且作为不同的实例可供彼此使用。

当我尝试使用它来保护尤里卡实例时，问题就开始了basic auth。这个想法是添加 spring 安全依赖，在 eureka 服务器上指定安全用户和密码，并将这些凭据放在defaultZoneurls 中（配置如下），但这似乎不起作用。

Eureka 实例甚至无法相互注册，当我尝试访问 eureka 门户网站时，系统会提示我输入登录表单，然后重定向到仪表板。所有仪表板都工作正常，需要访问凭据。

我正在使用Finchley.RC1带有 spring boot2.0.1.RELEASE和相同版本的spring cloudspring-boot-starter-security和spring-cloud-starter-netflix-eureka-server.

我究竟做错了什么？

*编辑

我已经找到了多种解决方案，例如Securing Eureka in Spring cloud，但它们都没有真正解决我的问题 - 正如您所看到的，我们的配置是相同的。

解决方案

解决了！

TL; DR 问题是由于CSRF某种原因，spring 无法对配置的用户进行身份验证application.yml

所以我不得不重写配置方法WebSecurityConfigurerAdapter来禁用 csrf 并创建 inMemory 用户。还从 application.yml 中删除了 spring.security.user 属性。

Eureka 服务器application.yml现在看起来像：

---
spring:
  profiles: primary
  application:
    name: eureka-server-clustered   
server:
  port: 8011  
eureka:
  instance:
    hostname: eureka-primary       
  client:
    registerWithEureka: true
    fetchRegistry: true        
    serviceUrl:
      defaultZone: http://admin:admin@eureka-secondary:8012/eureka,http://admin:admin@eureka-tertiary:8013/eureka

    hostname: eureka-secondary       
  client:
    registerWithEureka: true
    fetchRegistry: true        
    serviceUrl:
      defaultZone: http://admin:admin@eureka-primary:8013/eureka,http://admin:admin@eureka-tertiary:8011/eureka

spring:
  profiles: tertiary
  application:
    name: eureka-server-clustered     
server:
  port: 8013
eureka:
  instance:
    hostname: eureka-tertiary

    registerWithEureka: true
    fetchRegistry: true    
    serviceUrl:
      defaultZone: http://admin:admin@eureka-primary:8011/eureka,http://admin:admin@eureka-secondary:8012/eureka

新创建WebSecurityConfig的类：

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter{

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
        .passwordEncoder(NoOpPasswordEncoder.getInstance())
        .withUser("admin").password("admin")
        .authorities("ADMIN");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf()
                .disable()
            .authorizeRequests()
              .anyRequest().authenticated()
              .and()
              .httpBasic();
    }
}
