IoT Platform:QueryThingModel

最終更新日:Sep 15, 2023

Queries the features of the Thing Specification Language (TSL) model of a product.

Usage notes

TSL features include properties, services, and events.

If custom modules are added to the TSL model of a product and you do not specify the FunctionBlockId parameter in the request, the operation returns the TSL features of each custom module. If you specify the FunctionBlockId parameter in the request, the operation returns the TSL features of the specified custom module.

For more information about the data format of the ThingModelJson response parameter, see Data structure of ThingModelJson.

QPS limits

You can call this API operation up to 10 times per second per account.

Note

The Resource Access Management (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

QueryThingModel

The operation that you want to perform. Set the value to QueryThingModel.

IotInstanceId

String

No

iot_instc_pu****_c*-v64********

The instance ID. You can view the instance ID on the Overview tab of the IoT Platform console.

Important
  • If your instance has an ID, you must specify this parameter. If you do not specify this parameter, the request fails.

  • If the Overview tab or instance ID is not displayed in the IoT Platform console, you do not need to specify this parameter.

For more information about instances, see Overview.

ResourceGroupId

String

No

rg-acfm4l5tcwd****

The resource group ID.

Important

IoT Platform supports resource group management only by instance. The ResourceGroupId parameter is invalid. You do not need to specify this parameter.

ProductKey

String

No

a1BwAGV****

The ProductKey of the product.

ModelVersion

String

No

v1.0.0

The version number of the TSL model.

You can call the ListThingModelVersion operation to view the version numbers of the TSL model for a product.

If you do not specify this parameter, the TSL model that is in the draft state is queried. If you specify this parameter, the TSL model of the specified version is queried.

FunctionBlockId

String

No

BatteryModule

The identifier of the custom TSL module. Each identifier is unique in a product.

If you do not specify this parameter, the default module is queried.

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

Response parameters

Parameter

Type

Example

Description

Code

String

iot.system.SystemException

The error code returned if the request failed. For more information, see Error codes.
