绑定标签

功能介绍

应用服务器可调用此接口为指定资源绑定标签。当前支持标签的资源有Device(设备)。

调用方法

请参见如何调用API

URI

POST /v5/iot/{project_id}/tags/bind-resource

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,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

resource_type

String

参数说明:要绑定标签的资源类型。 取值范围

  • device:设备。

resource_id

String

参数说明:要绑定标签的资源id。例如,资源类型为device,那么对应的资源id就是device_id。 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。

tags

Array of TagV5DTO objects

参数说明:要绑定到指定资源的标签列表,标签列表中各项标签键值之间不允许重复,一个资源最多可以绑定10个标签。

表4 TagV5DTO

参数

是否必选

参数类型

描述

tag_key

String

参数说明:标签键,在同一资源下标签键唯一。绑定资源时,如果设置的键已存在,则将覆盖之前的标签值。如果设置的键值不存在,则新增标签。 取值范围:长度不超过64,只允许中文、字母、数字、以及_.-等字符的组合。

tag_value

String

参数说明:标签值。 取值范围:长度不超过128,只允许中文、字母、数字、以及_.-等字符的组合。

响应参数

请求示例

资源绑定标签,将标签绑定到设备id为d4922d8a的设备上。

POST https://{endpoint}/v5/iot/{project_id}/tags/bind-resource

{
  "resource_type" : "device",
  "resource_id" : "d4922d8a",
  "tags" : [ {
    "tag_key" : "testTagName",
    "tag_value" : "testTagValue"
  } ]
}
