查询实例列表

场景描述

本章节指导用户通过调用查询实例列表和详情接口，使用分页参数查询租户下所有DDS实例。

操作步骤

1. 指定limit与offset查询DDS实例列表。
   • 接口相关信息

     URI格式：GET https://{Endpoint}/v3/{project_id}/instances?id={id}&name={name}&mode={mode}&datastore_type={datastore_type}&vpc_id={vpc_id}&subnet_id={subnet_id}&offset={offset}&limit={limit}

     • {Endpoint}信息请从地区和终端节点获取。
     • {limit}可根据DDS实例数据调整。
     • 详情请参见查询实例列表和详情。
   • 请求示例
     • 根据指定limit与offset查询DDS实例列表

       https://dds.ap-southeast-1.myhuaweicloud.com/v3/0483b6b16e954cb88930a360d2c4e663/instances?offset=0&limit=1

   • 响应示例

     根据指定limit与offset查询DDS实例列表：

     }

2. 汇总查询结果。
   1. 参考1持续调用，如果查询的DDS实例列表为空，或者返回的body体中不存在instances字段，表明所有DDS实例查询完成。
   2. 汇总所有查询到的DDS实例即当前查询条件下的所有DDS实例。
