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	是	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	否	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	否	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
参数	是否必选	参数类型	描述
rule_name	否	String	参数说明：规则名称。取值范围：长度不超过256，只允许中文、字母、数字、以及_?'#().,&%@!-等字符的组合
description	否	String	参数说明：用户自定义的规则描述。
subject	是	RoutingRuleSubject object	参数说明：资源事件信息。
app_type	否	String	参数说明：租户规则的生效范围，默认GLOBAL，。取值范围： GLOBAL：生效范围为租户级。 APP：生效范围为资源空间级。如果类型为APP，创建的规则生效范围为携带的app_id指定的资源空间，不携带app_id则创建规则生效范围为默认资源空间。
app_id	否	String	参数说明：资源空间ID。。取值范围：长度不超过36，只允许字母、数字、下划线（_）、连接符（-）的组合。
select	否	String	参数说明：用户自定义sql select语句，最大长度2500，该参数仅供标准版和企业版用户使用。可填参数可参考帮助文档数据流转下各接口的请求参数，如notify_data.body。
where	否	String	参数说明：用户自定义sql where语句，最大长度2500，该参数仅供标准版和企业版用户使用,可填参数可参考帮助文档数据流转下各接口的请求参数，如notify_data.body。

表4 RoutingRuleSubject
参数	是否必选	参数类型	描述
resource	是	String	参数说明：资源名称。取值范围： device：设备。 device.property：设备属性。 device.message：设备消息。 device.message.status：设备消息状态。 device.status：设备状态。 batchtask：批量任务。 product：产品。 device.command.status：设备异步命令状态。
event	是	String	参数说明：资源事件。取值范围：与资源有关，不同的资源，事件不同。event需要与resource关联使用，具体的“resource：event”映射关系如下： device：create（设备添加） device：delete（设备删除） device：update（设备更新） device.status：update （设备状态变更） device.property：report（设备属性上报） device.message：report（设备消息上报） device.message.status：update（设备消息状态变更） batchtask：update （批量任务状态变更） product：create（产品添加） product：delete（产品删除） product：update（产品更新） device.command.status：update（设备异步命令状态更新）

响应参数

表5 响应Body参数
参数	参数类型	描述
rule_id	String	规则触发条件ID，用于唯一标识一个规则触发条件，在创建规则条件时由物联网平台分配获得。
rule_name	String	用户自定义的规则名称。
description	String	用户自定义的规则描述。
subject	RoutingRuleSubject object	资源事件信息，即资源变化事件。
app_type	String	租户规则的生效范围，取值如下： GLOBAL：生效范围为租户级 APP：生效范围为资源空间级。
app_id	String	资源空间ID
select	String	用户自定义sql select语句，最大长度2500，该参数仅供标准版和企业版用户使用。
where	String	用户自定义sql where语句，最大长度2500，该参数仅供标准版和企业版用户使用。
active	Boolean	规则条件的状态是否为激活。

请求示例

创建规则触发条件，触发条件为设备创建通知。

POST https://{endpoint}/v5/iot/{project_id}/routing-rule/rules

{
  "rule_name" : "rulename",
  "subject" : {
    "resource" : "device",
    "event" : "create"
  },
  "app_type" : "GLOBAL",
  "description" : "description"
}

创建规则触发条件，触发条件为属性上报。

POST https://{endpoint}/v5/iot/{project_id}/routing-rule/rules

{
  "rule_name" : "rulename",
  "subject" : {
    "resource" : "device.property",
    "event" : "report"
  },
  "app_type" : "GLOBAL",
  "description" : "description"
}

创建规则触发条件，触发条件为消息上报(根据sql进行topic筛选，基础版不支持该sql筛选能力)。

POST https://{endpoint}/v5/iot/{project_id}/routing-rule/rules

{
  "rule_name" : "rulename",
  "subject" : {
    "resource" : "device.message",
    "event" : "report"
  },
  "app_type" : "GLOBAL",
  "description" : "description",
