停止批量任务

功能介绍

应用服务器可调用此接口停止批量任务，目前只支持task_type为firmwareUpgrade，softwareUpgrade。如果task_id对应任务已经完成（成功、失败、部分成功，已经停止）或正在停止中，则不可以调用该接口。如果请求Body为{}，则调用该接口后会停止所有正在执行中、等待中和失败待重试状态的子任务。

调用方法

请参见如何调用API。

URI

POST /v5/iot/{project_id}/batchtasks/{task_id}/stop

表1 路径参数

参数

是否必选

参数类型

描述

task_id

是

String

参数说明：批量任务ID，创建批量任务时由物联网平台分配获得。 取值范围：长度不超过24，只允许小写字母a到f、数字的组合。

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 。

最小长度：1

最大长度：36
表3 请求Body参数

参数

是否必选

参数类型

描述

targets

否

Array of strings

执行批量任务的目标集合，最多支持100个目标，当task_type为firmwareUpgrade，softwareUpgrade时，此处填写device_id

响应参数

状态码： 200

表4 响应Body参数

参数

参数类型

描述

targets

Array of BatchTargetResult objects

批量操作目标结果集合
表5 BatchTargetResult

参数

参数类型

描述

target

String

执行批量任务的目标。

status

String

目标的执行结果，为success或failure

error_code

String

操作失败的错误码

error_msg

String

操作失败的错误描述

请求示例

  • 停止所有正在执行中，等待中和失败待重试状态的子任务。

    POST https://{endpoint}/v5/iot/{project_id}/batchtasks/{task_id}/stop

{ }

  • 停止执行指定目标集合的子任务

    POST https://{endpoint}/v5/iot/{project_id}/batchtasks/{task_id}/stop

{
  "targets" : [ "e495cf17-ff79-4294-8f64-4d367919d665" ]
}

响应示例

状态码： 200

OK

{
  "targets" : [ {
    "target" : "e495cf17-ff79-4294-8f64-4d367919d665",
    "status" : "failure",
    "error_code" : "IOTDA.014219",
    "error_msg" : "Invalid input. The target is not in the task"
  }, {
    "target" : "e495cf17-ff79-4294-8f64-4d367919d677",
    "status" : "success"
  } ]
}
