The organization ID which the model belongs to. How to get orgId>>

scope

Query

Request Header


Name

Required/Optional

Data Type

Description

response-format-type

Optional

String

Specified the structure type of the response parameters.

  • Only when the value is response-format-type, the response parameters will be returned as an array of ThingModel structure. For the return sample, see ThingModel Struct.

  • If a value other than response-format-type is provided or no value is provided, the response parameters will be returned as an array of Items structure. For the return sample, see Items Struct.

Request Parameters (Body)


Note

Use either expression or relationFilter to search, but not both together.

Name

Required/Optional

Data Type

Description

expression

Optional

String

The query expression, which supports sql-like query. The fields that are supported for query include: modelId, tags, attribute_tags, measurepoint_tags, service_tags, and event_tags. Supports fuzzy query and logical operators “and” and “or”. How to use expression>>

  • modelId: supports arithmetic operator “in”.

  • tags, attribute_tags, measurepoint_tags, service_tags, and event_tags: supports arithmetic operator “=”, “exists”, “not exists”, and “like”. Note: EnOS Edge does not support tag queries.

projection

Optional

Projection Struct

Enables you to crop the data result set returned in the request if needed. Only the specified fields will be returned in the data result set if this parameter is used. Otherwise all fields are returned. The supported fields are: modelId, modelIdPath, orgId, name, desc, tags, attributes, measurepoints, services, and events. For more details, see How does projection crop the result set.

Note: EnOS Edge does not support this parameter.

pagination

Optional

Pagination Request Struct

Lists the paging requirements in a request. When not specified, 10 records are displayed per page by default. Note that if the pageSize number is big, the API response time will increase significantly for large models. For optimal performance, it is recommended to have not more than 25 records per page. sorters is not supported to sort the response. For more details, see Pagination Request Struct.

relationFilter

Optional

RelationFilter Struct

Query based on the relationship between models. For more information, see RelationFilter Struct.
