分页查询

调试

您可以在API Explorer中直接运行调试该接口。

操作步骤

以GET /v2/{project _id}/elb/loadbalancers接口为例,示例帐号下有5个ELB对象,每页查询2个,示范分页查询遍历所有ELB对象的过程。

  1. Postman中设置好头部信息,将获取到的Token放入头部,设置limit为2,查询第一页,如下图。

    图1 分页查询-01

  2. 判断上一次查询返回实例数是否小于limit个数,如果小于则表示已查询到最后一页,否则需要继续查询下一页。示例中需要查询下一页,设置marker为上一页中最后一个ELB的ID,设置limit为2,查询第二页,如下图。

    图2 分页查询-02

  3. 同样判断方法,查询第三页,如下图。

    图3 分页查询-03

  4. 此时上一页查询响应个数小于limit,表示分页查询完成。

示例代码

2中请求体如下:

GET https://elb.cn-north-1.myhuaweicloud.com:443/v2/e2e095f1a31c467c89d4251cae136fa1/elb/loadbalancers?limit=2&marker=42aa24dd-32f7-482d-8612-6a4a23320457

2中响应体如下:
