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)。

表3 请求Body参数

参数

是否必选

参数类型

描述

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。

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。取值范围:1~2147483647
