QueryDeviceServiceData - Developer Guide (Cloud)| Alibaba Cloud Documentation Center

Limits

You can query only the service call records that are generated in the last 30 days.

Note The storage period of a service call record is calculated from the day when the service is called.
Each Alibaba Cloud account can run a maximum of 500 queries per second (QPS).

Note RAM users of an Alibaba Cloud account share the quota of the account.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters


Parameter	Type	Required	Example	Description
Action	String	Yes	QueryDeviceServiceData	The operation that you want to perform. Set the value to QueryDeviceServiceData.
EndTime	Long	Yes	1579249499000	The end of the time range to query. The value is a timestamp in milliseconds, for example 1579249499000.
StartTime	Long	Yes	1579249499000	The start of the time range to query. The value is a timestamp in milliseconds, for example 1579249499000.
IotInstanceId	String	No	iot_instc_pu***_c-v64********	The instance ID. This parameter is not required for public instances. However, this parameter is required for Enterprise Edition instances.
IotId	String	No	Q7uOhVRdZRRlDnTLv****00100	The ID of the device. It is the unique identifier that IoT Platform generated for the device. Note If you specify this parameter, you do not need to specify the ProductKey or DeviceName parameter. The IotId parameter specifies a unique identifier for the device, and corresponds to a combination of the ProductKey and DeviceName parameters. If you specify the IotId parameter and the combination of the ProductKey and DeviceName parameters at the same time, the IotId parameter is used.
ProductKey	String	No	a1BwAGV****	The ProductKey of the product to which the device belongs. Note If you specify this parameter, you must also specify the DeviceName parameter.
DeviceName	String	No	light	The name of the device. Note If you specify this parameter, you must also specify the ProductKey parameter.
Identifier	String	No	Set	The identifier of the service. The identifier of the service that is called. You can view the service identifier on the Define Feature tab of the IoT Platform console. You can also call the QueryThingModel operation to view the service identifier. Note If a service named testService belongs to a custom module named testFb, this parameter is set to testFb:testService. The custom module is not the default module. If you do not specify this parameter, the system queries all the service data of the default module and custom modules.
Asc	Integer	No	0	The sorting order of the returned service call records. Valid values: 0: descending 1: ascending
PageSize	Integer	No	10	The number of entries to return on each page. Maximum value: 50.

In addition to the preceding operation-specific request parameters, you must specify common request parameters when you call this API operation. For more information, see Common request parameters.

Response parameters


Parameter	Type	Example	Description
Code	String	iot.system.SystemException	The error code returned if the call fails. For more information, see Error codes.
Data	Struct		The service call records returned if the call succeeds.
List	Array of ServiceInfo		The array of service call records. Each element represents a service call record.
ServiceInfo
Identifier	String	Set	The identifier of the service.
InputData	String	{\"code\":200,\"data\":{},\"id\":\"100686\",\"message\":\"success\",\"version\":\"1.0\"}	The input parameter of the service. The value is a string in the MAP format. Syntax: key:value.

NextTime	Long	1579335899000	The start time of service call records on the next page. If you call the QueryDeviceServiceData operation to query the service call records on the next page, you must set the StartTime parameter to the value of this parameter.
NextValid	Boolean	true	Indicates whether the next page exists. true: The next page exists. false: The next page does not exist. If the return value of the NextValid parameter is true, you can use the value of the NextTime parameter as the value of the StartTime parameter when you query the next page of results.
ErrorMessage	String	A system exception has occurred.	The error message returned if the call fails.
RequestId	String	E55E50B7-40EE-4B6B-8BBE-D3ED55CCF565	The ID of the request.
Success	Boolean	true	Indicates whether the call succeeds. true: The call succeeded. false: The call failed.
