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：

• 查询实例ID：查询待删除Redis实例的ID。
• 批量删除实例：批量删除Redis实例。

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。

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",
     "instance": "9d78d0f4-a110-4bcd-8ca3-5aec414163c1"
    }
   ]
  }
