创建规则触发条件

功能介绍

应用服务器可调用此接口在物联网平台创建一条规则触发条件。

调用方法

请参见如何调用API

URI

POST /v5/iot/{project_id}/routing-rule/rules

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

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,一般华为云租户无需携带该参数,仅在物理多租场景下从管理面访问API时需要携带该参数。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。

表3 请求Body参数
