 # springcloud优雅下线服务
 
-
-
 ## 问题场景
 
 线上问题需要紧急修复部署，但是服务一直在跑，网关还会一直往服务中路由请求进行处理，如果直接停掉服务，客户端会出现业务中断的问题。因此需要在替换更新前先手动下线服务，这样用户请求不会被分发到下线的节点上，就可以直接进行更新而不影响用户体验。
 
-
-
 ## 实现
 
 ### 查询注册中心中服务的状态
 
 ```bash
-curl -GET -u eureka_username:eureka_password http://eureka_ip:eureka_port/eureka/apps/服务名称/实例ip:实例名称:实例port
+curl -X GET -u eureka_username:eureka_password http://eureka_ip:eureka_port/eureka/apps/服务名称/实例ip:实例名称:实例port
 ```
 
 例如
 
 ```bash
-curl -GET -u admin:admin123 http://127.0.0.1:19991/eureka/apps/app-platform/127.0.0.1:app-platform-1.0.0-SNAPSHOT:8001
+curl -X GET -u admin:admin123 http://127.0.0.1:19991/eureka/apps/app-platform/127.0.0.1:app-platform-1.0.0-SNAPSHOT:8001
 ```

 可以看到此时，服务状态为已经下线，不过还是要等到网关服务不再路由请求到该服务时再停掉服务。
