Eureka作为Spring Cloud常用的注册中心，其开放了以下接口：

注：

接口仅支持xml/json两种数据格式，请求时需设定Context-Type为**application/xml** 或者 **application/json**

VIP（虚拟IP地址）默认为实例的应用名

### 以下为实际请求内容实例： ###

context-path: /eureka

### GET /eureka/v2/apps ###

Accept:application/json 时响应json数据

### PUT /eureka/v2/apps/**appID**/**instanceID**/status?value=OUT\_OF\_SERVICE ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hc3RlcjMzNg_size_16_color_FFFFFF_t_70 3][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hc3RlcjMzNg_size_16_color_FFFFFF_t_70 4][]

**补充一个常见的手动服务下线接口**

**DELETE**  /eureka/v2/apps/appID/instanceID/status?value=UP(UP:可选)

请求地址示例：http://localhost:8080/eureka***/eureka/apps/APOLLO-ADMINSERVICE/bogon:apollo-adminservice:8090***

使用**HTTP.Method=Delete** 方式请求后，**APOLLO-ADMINSERVICE**服务***bogon:apollo-adminservice:8090实例***下线，从eureka的服务实例列表中摘除。
