上一篇搭建了一個OAuth2認證服務器,可以生成token,這篇來改造下之前的訂單微服務,使其能夠認這個token令牌。
本篇針對訂單服務要做三件事:
1,要讓他知道自己是資源服務器,他知道這件事后,才會在前邊加一個過濾器去驗令牌(配置@EnableResourceServer 配置類)
2,要讓他知道自己是什么資源服務器(配置資源服務器ID)
3,配置去哪里驗令牌,怎么驗令牌,要帶什么信息去驗 (配置@EnableWebSecurity 配置TokenServices,配置AuthenticationManager)
搭建資源服務器

application.yml:

server:
port: 9060
OrderInfo.java :

package com.nb.security.order; import lombok.AllArgsConstructor; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor public class OrderInfo { private Long productId; }
OrderController:

package com.nb.security.order; import lombok.extern.slf4j.Slf4j; import org.springframework.web.bind.annotation.*; import org.springframework.web.client.RestTemplate; @Slf4j @RestController @RequestMapping("/orders") public class OrderController { private RestTemplate restTemplate = new RestTemplate(); @PostMapping public OrderInfo create(@RequestBody OrderInfo info){ //查詢價格 // PriceInfo price = restTemplate.getForObject("http://localhost:9080/prices/"+info.getProductId(),PriceInfo.class); // log.info("price is "+price.getPrice()); return info; } @GetMapping public OrderInfo getInfo(@PathVariable Long id){ log.info("getInfo: id is "+id); return new OrderInfo(id); } }
啟動類:

package com.nb.security; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class NbOrderApiApplication { public static void main(String[] args) { SpringApplication.run(NbOrderApiApplication.class, args); } }
PriceInfo.java (暫時先不用):

package com.nb.security.order; import lombok.Data; import java.math.BigDecimal; @Data public class PriceInfo { private Long id; private BigDecimal price; }
++++++++++++++++++資源服務器現有的各個類結束++++++++++++++++++++++++++++
1,在資源服務器pom哩加上 oauth2的依賴:
<!--OAuth2--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-oauth2</artifactId> </dependency>
2,新建資源服務器配置類,繼承 ResourceServerConfigurerAdapter
package com.nb.security.resource.server; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer; import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter; import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer; /** * 資源服務器 * 配置了@EnableResourceServer ,所有發往nb-order-api的請求,都會去請求頭里找token,找不到不讓你過 */ @Configuration @EnableResourceServer//告訴nb-order-api,你就是資源服務器 public class OAuth2ResourceServerConfig extends ResourceServerConfigurerAdapter { @Override public void configure(ResourceServerSecurityConfigurer resources) throws Exception { //配置資源服務器的id,“現在我就是資源服務器order-server!!!” resources.resourceId("order-server"); } @Override public void configure(HttpSecurity http) throws Exception { /** * 進入nb-order-api的所有請求,哪些要攔截,哪些要放過,在這里配置 */ http.authorizeRequests() .antMatchers("/hello") .permitAll() //放過/haha不攔截 .anyRequest().authenticated();//其余所有請求都攔截 } }
ResourceServerConfigurerAdapter 有兩個方法:
開篇說的1、2、3中的1和2已經完成了,下面做第3件事,怎么驗令牌:
新建配置類:
package com.nb.security.resource.server; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.authentication.AuthenticationManager; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.oauth2.provider.authentication.OAuth2AuthenticationManager; import org.springframework.security.oauth2.provider.token.RemoteTokenServices; import org.springframework.security.oauth2.provider.token.ResourceServerTokenServices; /** * 怎么驗發往本服務的請求頭的令牌 * 1,自定義tokenServices ,說明去哪里去驗token * 2,重寫authenticationManagerBean()方法,將AuthenticationManager暴露為一個Bean * 要認證跟用戶相關的信息,一般用 AuthenticationManager * * 這樣配置了后,所有發往nb-order-api的請求, * 需要驗token的時候就會發請求去http://localhost:9090/oauth/check_token驗token,獲取到token對應的用戶信息 */ @Configuration @EnableWebSecurity public class OAuth2WebSecurityConfig extends WebSecurityConfigurerAdapter{ /** * 通過這個Bean,去遠程調用認證服務器,驗token * @return */ @Bean public ResourceServerTokenServices tokenServices(){ RemoteTokenServices tokenServices = new RemoteTokenServices(); tokenServices.setClientId("orderService");//在認證服務器配置的,訂單服務的clientId tokenServices.setClientSecret("123456");//在認證服務器配置的,訂單服務的ClientSecret tokenServices.setCheckTokenEndpointUrl("http://localhost:9090/oauth/check_token"); return tokenServices; } /** * 要認證跟用戶相關的信息,一般用 AuthenticationManager * 覆蓋這個方法,可以將AuthenticationManager暴露為一個Bean * * @return * @throws Exception */ @Bean @Override public AuthenticationManager authenticationManagerBean() throws Exception { OAuth2AuthenticationManager authenticationManager = new OAuth2AuthenticationManager(); authenticationManager.setTokenServices(tokenServices());//設置為自定義的TokenServices,去校驗令牌 return authenticationManager; } }
認證服務器關於訂單服務的配置:
啟動認證服務器,
啟動訂單 資源服務器,
訪問認證服務器獲取token : localhost:9090/oauth/token
拿着 token 去資源服務器創建訂單,注意,選擇bearer類型的token,生成的請求頭是這樣的(注:Authorization的value值,postman生成的是以Bearer開頭的,但是我看谷歌瀏覽器restclient插件生成的是bearer的B是小寫):
在資源服務器里,可以通過該注解獲取用戶名:
錯誤的情況:
如果把資源服務器配置的resourceId改成了order-server222,請求創建訂單,會受到如下的錯誤
如果資源服務器檢驗token的cilentID獲取clientSecret寫錯了,后台會報錯:
++++++++++++++++++++++分割線++++++++++++++++++++++
小結:
接上篇的認證服務器,本篇實現了資源服務器,以及與認證服務器的交互,怎么去驗令牌。
遺留疑問:
認證服務器里面,配置資源服務器secret的時候,用passwordEncoder對123456進行了加密,而在資源服務器里,clientSecret確實明文的123456,這兩者不需要一致么?
認證服務器里對資源服務器ClientId、 ClientSecret配置:
資源服務器驗令牌攜帶的ClientId、 ClientSecret:
