2. 根据公网IP查询公网IP详情
   
   - 接口相关信息 URI格式： GET /v1/{project_id}/publicips
     详情请参见"[查询弹性公网IP列表](https://support.huaweicloud.com/api-eip/eip_api_0003.html)"。
     
   
   
   
   - 请求示例 GET https://*{endpoint* *}*/v1/743b4c0428d945316666666666666666/publicips?public_ip_address=121.xx.xx.64
     {endpoint}信息请从[地区和终端节点](https://console.huaweicloud.com/apiexplorer/#/endpoint/ECS)获取。
     public_ip_address参数传入的公网IP地址从[1]的返回信息中获取，从返回body体中的"server"下的"address"信息中找到"OS-EXT-IPS:type"为"floating"的"addr"字段，即为公网IP地址。
