示例3:批量删除Redis实例

场景描述

本章节指导用户通过API批量删除Redis实例。API的调用方法请参见如何调用API

涉及接口

批量删除Redis实例时,需要进行查询待删除实例的ID,涉及的API如下:

步骤1:查询待删除实例的ID

  1. 查询实例ID。

    • 接口相关信息

      URI格式:GET /v2/{project_id}/instances

    • 请求示例

      GET https://{dcs_endpoint}/v2/7d80ae32f57b499eb8781f9a9f57c538/instances

      {dcs_endpoint}信息,请从地区和终端节点获取。

    • 响应示例

  2. 根据需要,记录要删除实例的instance_id。

步骤2:批量删除实例

  • 接口相关信息

    URI格式:DELETE /v2/{project_id}/instances

  • 请求示例

    DELETE https://{dcs_endpoint}/v2/{project_id}/instances

    {dcs_endpoint}信息,请从地区和终端节点获取。

    Body:

    {
     "instances": [
      "aabe73af-1db8-4401-b39c-c56996023989",
      "9d78d0f4-a110-4bcd-8ca3-5aec414163c1"
     ]
    }
  • 响应示例
    {
     "results": [
      {
       "result": "success",
       "instance": "aabe73af-1db8-4401-b39c-c56996023989"
      },
      {
       "result": "success",
