如何使用基本身份验证保护 Spring Cloud Eureka 服务？

Question

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 basic auth 和 this 来保护 eureka 实例时，问题就开始了。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defaultZone url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 spring cloud Finchley.RC1 和 spring boot 2.0.1.RELEASE 以及相同版本的 spring-boot-starter-security 和 spring-cloud-starter-netflix-eureka-server。

我做错了什么？

*编辑

我已经找到了多个类似 Securing Eureka in Spring cloud 的解决方案，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。

Answer 1

解决了！

TL;DR 问题是CSRF，由于某种原因，spring 无法验证在application.yml 中配置的用户

所以我不得不重写 WebSecurityConfigurerAdapter 的配置方法来禁用 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
---
spring:
  profiles: secondary
  application:
    name: eureka-server-clustered      
server:
  port: 8012
eureka:
  instance:
    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       
  client:
    registerWithEureka: true
    fetchRegistry: true    
    serviceUrl:
      defaultZone: http://admin:admin@eureka-primary:8011/eureka,http://admin:admin@eureka-secondary:8012/eureka  

新创建的WebSecurityConfig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();
    }
}

Answer 2

Greenwich.SR1 也有类似的问题。 使用spring.security.user.name 启用安全性允许我使用用户名/密码登录，但我的服务无法注册 Eureka 服务。 我让它工作了，如上所述，原因确实是CSRF 这解决了它：

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().ignoringAntMatchers("/eureka/**");
        super.configure(http);
    }

}

Answer 3

在你的 pom.xml 中导入 spring-security ：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

并将其放入您的 application.yaml 中：

security:
  user:
    name: admin
    password: password

它应该可以工作！
