新建数据流转流控策略

功能介绍

应用服务器可调用此接口在物联网平台创建数据流转流控策略。

调用方法

请参见如何调用API。

URI

POST /v5/iot/{project_id}/routing-rule/flowcontrol-policy

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
policy_name	否	String	参数说明：数据流转流控策略名称。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。最小长度：1 最大长度：256
description	否	String	参数说明：用户自定义的数据流转流控策略描述。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。最小长度：1 最大长度：256
scope	否	String	参数说明：流控策略作用域. 取值范围： USER：租户级流控策略。 CHANNEL：转发通道级流控策略。 RULE：转发规则级流控策略。 ACTION：转发动作级流控策略。
scope_value	否	String	参数说明：流控策略作用域附加值。 scope取值为USER时，可不携带该字段，表示租户级流控。 scope取值为CHANNEL时，取值范围：HTTP_FORWARDING、DIS_FORWARDING、OBS_FORWARDING、AMQP_FORWARDING、DMS_KAFKA_FORWARDING。 scope取值为RULE时，该字段为对应的ruleId。 scope取值为ACTION时，该字段为对应的actionId。
limit	否	Integer	参数说明：数据转发流控大小。单位为tps，取值范围为1~1000的整数，默认为1000. 最小值：1 最大值：1000 缺省值：1000
