Querying the Result of a Specified Upgrade Task

Typical Scenario

After a device software or firmware upgrade task is created, an NA can call this API to query details about the upgrade task, including the configuration and execution status.

API Function

This API is used by an NA to query details about a software or firmware upgrade task, including the configuration and execution status.

API Description

1	public function queryUpgradeTask($operationId, $accessToken)

Parameter Description

Parameter	Mandatory or Optional	Location	Description
$operationId	Mandatory	path	Identifies an operation task. The value of this parameter is returned by the IoT platform after the operation task is created.
$accessToken	Mandatory	header	This parameter is set to the value of the access token obtained by calling the Authentication API.

Error Code

HTTP Status Code	Error Code	Error Description	Remarks
400	120015	Bad request error.	A request error occurs. Recommended handling: Check whether the format of fileId carried in the API request is correct.
400	123029	pageNo or pageSize beyond the limit.	The value of pageNo or pageSize exceeds the upper limit. Recommended handling: Change the value of pageNo or pageSize to a valid value.
403	1010009	app throttle exceed.	The NA calls the API at a frequency that exceeds the flow control threshold (100 calls per minute by default). Recommended handling: Contact IoT platform maintenance personnel to adjust the flow control threshold or control the API call frequency.
403	1010005	App_key or access_token is invalid.	The access token is invalid. Recommended handling: Check whether accessToken carried in the API request is correct.
404	123009	The requested task does not exist.	The queried task does not exist. Recommended handling: Check whether operationId carried in the API request is correct.
