# 将弹性公网IP的反向解析记录恢复为默认值 - DeletePtr #### 功能介绍 将弹性公网IP的反向解析记录恢复为默认值。 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-dns/zh-cn_topic_0037134405.html)。 #### 授权信息 账号具备所有API的调用权限，如果使用账号下的IAM用户调用当前API，该IAM用户需具备调用API所需的权限。 - 如果使用角色与策略授权，具体权限要求请参见[权限和授权项](https://support.huaweicloud.com/api-dns/dns_api_70000.html)。 - 如果使用身份策略授权，需具备如下身份策略权限。 | 授权项 | 访问级别 | 资源类型（\*为必须） | 条件键 | 别名 | 依赖的授权项 | |:---|:---|:---|:---|:---|:---| | dns:ptr:delete | Write | ptr \* | - g:ResourceTag/\ - g:EnterpriseProjectId | dns:ptr:set | - | #### URI DELETE /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 | 是 | String | **参数解释：** 反向解析ID。 获取方式：通过查询反向解析列表（ListPtrRecords）接口获取。 **约束限制：** 不涉及。 **取值范围：** 不涉及。 **默认取值：** 不涉及。 | #### 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 | 是 | String | **参数解释：** 用户Token，用于用户身份认证，调用接口时需在请求头中携带该Token以验证用户身份。 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）。 获取用户Token请参见[获取用户Token](https://support.huaweicloud.com/api-dns/dns_api_30003.html)。 **约束限制：** 不涉及。 **取值范围：** 不涉及。 **默认取值：** 不涉及。 | #### 响应参数 **状态码：202** 无 #### 请求示例 将弹性公网IP的反向解析记录恢复为默认值。 ``` DELETE https://{Endpoint}/v2.1/ptrs/9a175b97889f2f3501889fa3a8a66ed0 ``` #### 响应示例 **状态码：202** ``` null ``` #### SDK代码示例 SDK代码示例如下。 - [Java] ``` package com.huaweicloud.sdk.test; import com.huaweicloud.sdk.core.auth.ICredential; import com.huaweicloud.sdk.core.auth.BasicCredentials; import com.huaweicloud.sdk.core.exception.ConnectionException; import com.huaweicloud.sdk.core.exception.RequestTimeoutException; import com.huaweicloud.sdk.core.exception.ServiceResponseException; import com.huaweicloud.sdk.dns.v2.region.DnsRegion; import com.huaweicloud.sdk.dns.v2.*; import com.huaweicloud.sdk.dns.v2.model.*; public class DeletePtrSolution { public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great security risks.
