统计设备下的历史命令总数

功能介绍

统计设备下的历史命令总数。

调用方法

请参见如何调用API

URI

POST /v5/iot/{project_id}/devices/{device_id}/async-commands-history/count

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

device_id

String

参数说明:下发命令的设备ID,用于唯一标识一个设备,在注册设备时由物联网平台分配获得。

取值范围:长度不超过128,只允许字母、数字、下划线(_)、连接符(-)的组合。

表2 Query参数

参数

是否必选

参数类型

描述

start_time

String

参数说明:查询命令下发时间在startTime之后的记录,格式:yyyyMMdd'T'HHmmss'Z',如20151212T121212Z。

end_time

String

参数说明:查询命令下发时间在endTime之前的记录,格式:yyyyMMdd'T'HHmmss'Z',如20151212T121212Z。

status

String

参数说明:命令状态。

command_name

String

参数说明:命令名称。

请求参数

表3 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

响应参数

状态码: 200

表4 响应Body参数

参数

参数类型

描述

count

Long

满足查询条件的记录总数。

请求示例

统计设备下的历史命令总数。

POST https://{endpoint}/v5/iot/{project_id}/devices/{device_id}/async-commands-history/count

响应示例

状态码: 200

OK

{
  "count" : 100
}
