查询弹性公网IP的反向解析记录

功能介绍

查询弹性公网IP的反向解析记录。

调用方法

请参见如何调用API

URI

GET /v2.1/ptrs/{ptr_id}

表1 路径参数

参数

是否必选

参数类型

描述

ptr_id

String

反向解析ID。

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

用户Token。

通过调用IAM服务获取用户Token接口获取(响应消息头中X-Subject-Token的值)。

响应参数

状态码:200

表3 响应Body参数

参数

参数类型

描述

publicip

PublicIpRes object

EIP对象。

ptrdnames

Array of strings

反向解析记录对应的域名列表,最大个数不超过10个。

id

String

反向解析记录的ID。

description

String

对反向解析记录的描述。

ttl

Integer

反向解析记录在本地DNS服务器的缓存时间,缓存时间越长更新生效越慢,以秒为单位。

status

String

资源状态。

links

pageLink object

指向当前资源或者其他资源的链接。当查询需要分页时,需要包含一个next链接指向下一页。

enterprise_project_id

String

反向解析关联的企业项目ID,长度不超过36个字符。

表4 PublicIpRes

参数

参数类型

描述

region

String

弹性公网IP(EIP)所属的区域。

id

String

弹性公网IP(EIP)的ID。

address

String

弹性公网IP(EIP)。

请求示例
