解绑标签

功能介绍

应用服务器可调用此接口为指定资源解绑标签。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/unbind-resource

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，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

是

String

参数说明：要绑定标签的资源类型。

取值范围：

  • device：设备。

resource_id

是

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。

tag_keys

是

Array of strings

参数说明：指定资源要解绑的标签键列表，标签键列表中各项之间不允许重复，不能填写不存在的标签键值

取值范围：标签键长度不超过64，只允许中文、字母、数字、以及_.-等字符的组合。

响应参数

无

请求示例

资源解绑标签，将标签testkey从设备id为d4922d8a的设备解绑。

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

{
  "resource_type" : "device",
  "resource_id" : "d4922d8a",
  "tag_keys" : [ "testTag" ]
}

响应示例

无

SDK代码示例

SDK代码示例如下。

资源解绑标签，将标签testkey从设备id为d4922d8a的设备解绑。
