今天就跟大家聊聊有關Spring Cloud中怎么利用OAUTH2實現認證授權,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結了以下內容,希望大家根據這篇文章可以有所收獲。
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
: 用戶
Client
:使用API的客戶端(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是在用戶的設備上的,如在手機上調起微信來進行認證授權)
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
作為賬戶存儲,Redis
作為Token
存儲,使用docker-compose
在服務器上啟動Postgres
和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 OAuth3服務配置
Redis
用來存儲token
,服務重啟后,無需重新獲取token
.
@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) .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,可以隨意設置 .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信息,所以auth-server
也是一個Resource Server
@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(); } //不定義沒有password grant_type @Override @Bean public AuthenticationManager authenticationManagerBean() throws Exception { return super.authenticationManagerBean(); } }
2.4 權限設計
采用用戶(SysUser)
角色(SysRole)
權限(SysAuthotity)
設置,彼此之間的關系是多對多
。通過DomainUserDetailsService
加載用戶和權限。
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 ##很重要 security: oauth3: resource: filter-order: 3
2.6 測試數據
data.sql
里初始化了兩個用戶admin
->ROLE_ADMIN
->query_demo
,wyf
->ROLE_USER
3.order-service
3.1 Resource服務配置
@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 用戶信息配置
order-service
是一個簡單的微服務,使用auth-server
進行認證授權,在它的配置文件指定用戶信息在auth-server
的地址即可:
security: oauth3: resource: id: order-service user-info-uri: http://localhost:8080/uaa/user prefer-token-info: false
3.3 權限測試控制器
具備authority
未query-demo
的才能訪問,即為admin
用戶
@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并開啟Oauth3 client支持
@Configuration @EnableOAuth3Sso 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: oauth3: 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 演示
5.1 客戶端調用
使用Postman
向http://localhost:8080/uaa/oauth/token
發送請求獲得access_token
(admin用戶的如7f9b54d4-fd25-4a2c-a848-ddf8f119230b
)
admin用戶
wyf用戶
