Spring Cloud下基于OAUTH2认证受权的实现

在Spring Cloud须要使用OAUTH2来实现多个微服务的统一认证受权，经过向OAUTH服务发送某个类型的grant type进行集中认证和受权，从而得到access_token，而这个token是受其余微服务信任的，咱们在后续的访问能够经过access_token来进行，从而实现了微服务的统一认证受权。android

本示例提供了四大部分：git

eureka:服务注册和发现的基本模块
auth:OAUTH2认证受权中心
account:普通微服务，用来验证认证和受权
gateway:边界网关(全部微服务都在它以后)

OAUTH2中的角色：github

Resource Server:被受权访问的资源
Authotization Server：OAUTH2认证受权中心
Resource Owner：用户
Client：使用API的客户端(如Android 、IOS、web app)

Grant Type：web

authorization_code:
implicit:
password:
refrsh_token:

1.基础环境

使用Postgres做为帐户存储，Redis做为Token存储，使用docker-compose在服务器上启动Postgres和Redis。redis

Redis:
  image: sameersbn/redis:latest
  ports:
    - "6379:6379"
  volumes:
    - /srv/docker/redis:/var/lib/redis:Z
  restart: always

PostgreSQL:
  restart: always
  image: sameersbn/postgresql:9.6-2
  ports:
    - "5432:5432"
  environment:
    - DEBUG=false

    - DB_USER=wang
    - DB_PASS=yunfei
    - DB_NAME=order
  volumes:
    - /srv/docker/postgresql:/var/lib/postgresql:Z

2.auth-server

2.1 OAuth2服务配置

Redis用来存储token，服务重启后，无需从新获取token.spring

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private RedisConnectionFactory connectionFactory;


    @Bean
    public RedisTokenStore tokenStore() {
        return new RedisTokenStore(connectionFactory);
    }


    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
                .authenticationManager(authenticationManager)
                .userDetailsService(userDetailsService)//若无，refresh_token会有UserDetailsService is required错误
                .tokenStore(tokenStore());
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("android")
                .scopes("xx") //此处的scopes是无用的，能够随意设置
                .secret("android")
                .authorizedGrantTypes("password", "authorization_code", "refresh_token")
            .and()
                .withClient("webapp")
                .scopes("xx")
                .authorizedGrantTypes("implicit");
    }
}

2.2 Resource服务配置

auth-server提供user信息，因此auth-server也是一个Resource Serversql

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .exceptionHandling()
                .authenticationEntryPoint((request, response, authException) -> response.sendError(HttpServletResponse.SC_UNAUTHORIZED))
            .and()
                .authorizeRequests()
                .anyRequest().authenticated()
            .and()
                .httpBasic();
    }
}

@RestController
public class UserController {

    @GetMapping("/user")
    public Principal user(Principal user){
        return user;
    }
}

2.3 安全配置

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {



    @Bean
    public UserDetailsService userDetailsService(){
        return new DomainUserDetailsService();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .userDetailsService(userDetailsService())
                .passwordEncoder(passwordEncoder());
    }

    @Bean
    public SecurityEvaluationContextExtension securityEvaluationContextExtension() {
        return new SecurityEvaluationContextExtension();
    }

    //不定义没有password grant_type
    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
    


}

2.4 权限设计

采用用户(SysUser)<->角色(SysRole)<->权限(SysAuthotity)设置，彼此之间的关系是多对多。经过DomainUserDetailsService 加载用户和权限。docker

2.5 配置

spring:
  profiles:
    active: ${SPRING_PROFILES_ACTIVE:dev}
  application:
      name: auth-server

  jpa:
    open-in-view: true
    database: POSTGRESQL
    show-sql: true
    hibernate:
      ddl-auto: update
  datasource:
    platform: postgres
    url: jdbc:postgresql://192.168.1.140:5432/auth
    username: wang
    password: yunfei
    driver-class-name: org.postgresql.Driver
  redis:
    host: 192.168.1.140

server:
  port: 9999


eureka:
  client:
    serviceUrl:
      defaultZone: http://${eureka.host:localhost}:${eureka.port:8761}/eureka/



logging.level.org.springframework.security: DEBUG

logging.leve.org.springframework: DEBUG

2.6 测试数据

data.sql里初始化了两个用户admin->ROLE_ADMIN->query_demo,wyf->ROLE_USERapi

3.account

3.1 Resource服务配置

@Configuration
@EnableResourceServer
public class ResourceServerConfig  extends ResourceServerConfigurerAdapter{

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .exceptionHandling()
                .authenticationEntryPoint((request, response, authException) -> response.sendError(HttpServletResponse.SC_UNAUTHORIZED))
            .and()
                .authorizeRequests()
                .anyRequest().authenticated()
            .and()
                .httpBasic();
    }
}

3.2 用户信息配置

account是一个简单的微服务，使用auth-server进行认证受权，在它的配置文件指定用户信息在auth-server的地址便可：安全

security:
  oauth2:
    resource:
      id: order-service
      user-info-uri: http://localhost:8080/uaa/user
      prefer-token-info: false

3.3 权限测试控制器

具有authority未query-demo的才能访问，即为admin用户

@RestController
public class DemoController {
    @GetMapping("/demo")
    @PreAuthorize("hasAuthority('query-demo')")
    public String getDemo(){
        return "good";
    }
}

4 api-gateway

api-gateway在本例中有2个做用：

自己做为一个client，使用implicit
做为外部app访问的方向代理

4.1 关闭csrf并开启Oauth2 client支持

@Configuration
@EnableOAuth2Sso
public class SecurityConfig extends WebSecurityConfigurerAdapter{
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.csrf().disable();

    }

}

4.2 配置

zuul:
  routes:
    uaa:
      path: /uaa/**
      sensitiveHeaders:
      serviceId: auth-server
    order:
      path: /order/**
      sensitiveHeaders:
      serviceId: order-service
  add-proxy-headers: true

security:
  oauth2:
    client:
      access-token-uri: http://localhost:8080/uaa/oauth/token
      user-authorization-uri: http://localhost:8080/uaa/oauth/authorize
      client-id: webapp
    resource:
      user-info-uri: http://localhost:8080/uaa/user
      prefer-token-info: false

4.3 服务之间互调

feign client没有将access token放入请求头里,需定义一个OAuth2FeignRequestInterceptor的bean：

5 演示

5.1 客户端调用

使用Postman向http://localhost:8080/uaa/oauth/token发送请求得到access_token(admin用户的如7f9b54d4-fd25-4a2c-a848-ddf8f119230b)

admin用户

wyf用户

5.2 api-gateway中的webapp调用

暂时没有作测试，下次补充。
