查询设备策略绑定的目标列表

功能介绍

应用服务器可调用此接口在物联网平台上查询指定策略ID下绑定的目标列表。

调用方法

请参见如何调用API

URI

POST /v5/iot/{project_id}/device-policies/{policy_id}/list-targets

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

参数说明:项目ID。获取方法请参见 获取项目ID

policy_id

String

策略ID

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

参数说明:用户Token。通过调用IAM服务 获取IAM用户Token接口获取,接口返回的响应消息头中“X-Subject-Token”就是需要获取的用户Token。简要的获取方法样例请参见 Token认证

Instance-Id

String

参数说明:实例ID。物理多租下各实例的唯一标识,建议携带该参数,在使用专业版时必须携带该参数。您可以在IoTDA管理控制台界面,选择左侧导航栏“总览”页签查看当前实例的ID,具体获取方式请参考查看实例详情

表3 请求Body参数

参数

是否必选

参数类型

描述

target_type

String

参数说明:策略绑定的目标类型。

取值范围:device|product|app,device表示设备,product表示产品,app表示整个资源空间。

limit

Integer

参数说明:分页查询时每页显示的记录数。

取值范围:1-50的整数,默认值为10。

marker

String

参数说明:上一次分页查询结果中最后一条记录的ID,在上一次分页查询时由物联网平台返回获得。分页查询时物联网平台是按marker也就是记录ID降序查询的,越新的数据记录ID也会越大。若填写marker,则本次只查询记录ID小于marker的数据记录。若不填写,则从记录ID最大也就是最新的一条数据开始查询。如果需要依次查询所有数据,则每次查询时必须填写上一次查询响应中的marker值。

取值范围:长度为24的十六进制字符串,默认值为ffffffffffffffffffffffff。

offset

Integer

参数说明:表示从marker后偏移offset条记录开始查询。默认为0,取值范围为0-500的整数。当offset为0时,表示从marker后第一条记录开始输出。限制offset最大值是出于API性能考虑,您可以搭配marker使用该参数实现翻页,例如每页50条记录,1-11页内都可以直接使用offset跳转到指定页,但到11页后,由于offset限制为500,您需要使用第11页返回的marker作为下次查询的marker,以实现翻页到12-22页。

取值范围:0-500的整数,默认为0。

响应参数

状态码: 200

表4 响应Body参数

参数

参数类型

描述

targets

Array of PolicyTargetBase objects

策略绑定信息列表。

page

Page object

查询结果的分页信息。

表5 PolicyTargetBase

参数

参数类型

描述

target_type

String

参数说明:策略绑定的目标类型。

取值范围:device|product|app,device表示设备,product表示产品,app表示整个资源空间。

target_id

String

策略绑定的目标ID

表6 Page

参数

参数类型

描述

count

Long

满足查询条件的记录总数。

marker

String

本次分页查询结果中最后一条记录的ID,可在下一次分页查询时使用。

请求示例

查询指定策略id下绑定的目标列表

POST https://{endpoint}/v5/iot/{project_id}/device-policies/{policy_id}/list-targets

{
  "target_type" : "device"
}

响应示例

状态码: 200

OK

{
  "targets" : [ {
    "target_type" : "device",
    "target_id" : "64a7ba7ef9cb063d27e16b97_123456"
  } ],
  "page" : {
    "marker" : "5c90fa7d3c4e4405e8525079",
    "count" : 1
  }
}
