Spring Cloud下基於OAUTH2認證授權的實現樣本,cloudoauth2
在Spring Cloud需要使用OAUTH2來實現多個微服務的統一認證授權,通過向OAUTH服務發送某個類型的grant type進行集中認證和授權,從而獲得access_token,而這個token是受其他微服務信任的,我們在後續的訪問可以通過access_token來進行,從而實現了微服務的統一認證授權。
本樣本提供了四大部分:
discovery-service:服務註冊和發現的基本模組
auth-server:OAUTH2認證授權中心
order-service:普通微服務,用來驗證認證和授權
api-gateway:邊界網關(所有微服務都在它之後)
OAUTH2中的角色:
Resource Server:被授權訪問的資源
Authotization Server:OAUTH2認證授權中心
Resource Owner: 使用者
Client:使用API的用戶端(如Android 、IOS、web app)
Grant Type:
Authorization Code:用在服務端應用之間
Implicit:用在移動app或者web app(這些app是在使用者的裝置上的,如在手機上調起來進行認證授權)
Resource Owner Password Credentials(password):應用直接都是受信任的(都是由一家公司開發的,本例子使用
Client Credentials:用在應用API訪問。
1.基礎環境
使用Postgres作為賬戶儲存,Redis作為Token儲存,使用docker-compose在伺服器上啟動Postgres和Redis。
Redis: image: sameersbn/redis:latest ports: - "6379:6379" volumes: - /srv/docker/redis:/var/lib/redis:Z restart: alwaysPostgreSQL: 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服務配置
Redis用來儲存token,服務重啟後,無需重新擷取token.
@Configuration@EnableAuthorizationServerpublic 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) .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") //此處的scopes是無用的,可以隨意設定 .secret("android") .authorizedGrantTypes("password", "authorization_code", "refresh_token") .and() .withClient("webapp") .scopes("xx") .authorizedGrantTypes("implicit"); }}
2.2 Resource服務配置
auth-server提供user資訊,所以auth-server也是一個Resource Server
@Configuration@EnableResourceServerpublic 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(); }}
@RestControllerpublic class UserController { @GetMapping("/user") public Principal user(Principal user){ return user; }}
2.3 安全配置
@Configurationpublic 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(); } //不定義沒有password grant_type @Override @Bean public AuthenticationManager authenticationManagerBean() throws Exception { return super.authenticationManagerBean(); }}
2.4 許可權設計
採用使用者(SysUser) 角色(SysRole) 許可權(SysAuthotity)設定,彼此之間的關係是多對多。通過DomainUserDetailsService 載入使用者和許可權。
2.5 配置
spring: profiles: active: ${SPRING_PROFILES_ACTIVE:dev} application: name: auth-server jpa: open-in-view: true database: POSTGRESQL show-sql: true hibernate: ddl-auto: update datasource: platform: postgres url: jdbc:postgresql://192.168.1.140:5432/auth username: wang password: yunfei driver-class-name: org.postgresql.Driver redis: host: 192.168.1.140server: port: 9999eureka: client: serviceUrl: defaultZone: http://${eureka.host:localhost}:${eureka.port:8761}/eureka/logging.level.org.springframework.security: DEBUGlogging.leve.org.springframework: DEBUG##很重要security: oauth2: resource: filter-order: 3
2.6 測試資料
data.sql裡初始化了兩個使用者admin->ROLE_ADMIN->query_demo,wyf->ROLE_USER
3.order-service
3.1 Resource服務配置
@Configuration@EnableResourceServerpublic 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 使用者資訊配置
order-service是一個簡單的微服務,使用auth-server進行認證授權,在它的設定檔指定使用者資訊在auth-server的地址即可:
security: oauth2: resource: id: order-service user-info-uri: http://localhost:8080/uaa/user prefer-token-info: false
3.3 許可權測試控制器
具備authority未query-demo的才能訪問,即為admin使用者
@RestControllerpublic class DemoController { @GetMapping("/demo") @PreAuthorize("hasAuthority('query-demo')") public String getDemo(){ return "good"; }}
4 api-gateway
api-gateway在本例中有2個作用:
- 本身作為一個client,使用
implicit
- 作為外部app訪問的方向代理
4.1 關閉csrf並開啟Oauth2 client支援
@Configuration@EnableOAuth2Ssopublic 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: truesecurity: 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
5 示範
5.1 用戶端調用
使用Postman向http://localhost:8080/uaa/oauth/token發送請求獲得access_token(admin使用者的如7f9b54d4-fd25-4a2c-a848-ddf8f119230b)
admin使用者
wyf使用者
5.2 api-gateway中的webapp調用
暫時沒有做測試,下次補充。
