Request Parameters (Body)¶

Note

Use either expression or filter to search, but not both together. EnOS Cloud only supports searching by expression while EnOS Edge supports expression or filter.

Name	Mandatory/Optional	Data Type	Description
expression	Optional	String	The conditions used for the search. The fields that are supported for query include: `assetIds`, `modelIds`, `rootModelIds`, `name`, `attributes`, `tags`, `treeId`, `productKey` and `deviceKey`. `assetIds`, `modelIds`, and `rootModelIds`: support “in” `productKey` and `deviceKey`: supports arithmetic operator “=” and fuzzy inquiry (like) `createTime` ：support =, <=, >= `tags.*` : supports fuzzy inquiry (like), “in” and “exists” `name`: supports fuzzy inquiry of specified language: `name like 'xxx'`: fuzzy inquiry of default name, Chinese name, and English name `name.default like 'xxx'`: fuzzy inquiry of default name `name.zh_CN like 'xxx'`: fuzzy inquiry of Chinese name, if no Chinese name, fuzzy inquiry of default name `name.en_US like 'xxx'`: fuzzy inquiry of English name, if no English name, fuzzy inquiry of default name Do not use this with `filter`. How to use expression>>
filter	Optional	AssetSearchVo Struct	The conditions used for the search. Do not use this with `expression`. For more details, see AssetSearchVo Struct >>. Note: EnOS Cloud does not support this parameter.
pagination	Optional	Pagination Request Struct	Lists the paging requirements in a request. When not specified, 100 records are displayed per page by default. The maximum records per page is 1000 but for optimal performance, it is recommended to have not more than 50 records per page. `sorters` is not supported to sort the response. For more details, see Pagination Request Struct
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. For more details, see How does projection crop the result set? Note: EnOS Edge does not support this parameter.

AssetSearchVo Struct ¶

Name	Mandatory/Optional	Data Type	Description
assetIds	Optional	String Array	The list of asset IDs.
modelIds	Optional	String Array	The list of model IDs.
rootModelIds	Optional	String Array	The list of root model IDs.
attributes	Optional	Map (Key is of String type, Value is of Object type)	The attributes of the model which the asset belongs to.
tags	Optional	Map (Key and Value are of String type)	The user-defined tags.
nameLike	Optional	StringI18n	The asset name, which supports fuzzy query. For more details on the structure and locales supported, see Internationalized name struct >>

Response Parameters¶

Name	Data Type	Description
data	Array	A list of the assets. Information include `assetId`, `name`, and `attributes` from Asset Struct.

Error Codes¶

Code	Error Information	Description
