示例3：查询指定主机集群的主机列表

场景描述

本章以软件开发生产线用户为例，指导您通过API查询指定主机集群的主机列表。

API的调用方法请参见如何调用API。

前提条件

用户已经创建软件开发生产线项目，并且项目下有主机集群。

总体思路

先通过用户token查询主机集群列表，再通过主机集群group_id，查询指定主机集群的主机列表，步骤如下：

1. 查询用户的所有主机集群。
2. 查询某主机集群对应的主机列表。

步骤1：查询用户的所有主机集群

• 接口信息：

  URI：GET /v2/host-groups

• 请求示例：

  GET  https://{endpoint}/v2/host-groups?region_name=ap-southeast-3&project_id=6039d4480efc4dddb178abff98719913&offset=1&limit=10&sort_key=create_time&sort_dir=DESC

• 响应示例：
