Search Related Asset Node¶

Search for assets under the specified asset tree based on the relationship with a known asset.

Operation Permissions¶

Required Authorization	Required Operation Permission
Asset Tree Management	Read

Request Format¶

POST https://{apigw-address}/asset-tree-service/v2.1/asset-nodes?action=searchRelatedAsset

Request Parameters (URI)¶

Name	Location (Path/Query)	Mandatory/Optional	Data Type	Description
orgId	Query	Mandatory	String	The organization ID which the asset belongs to. How to get orgId>>
treeId	Query	Mandatory	String	The asset tree ID. How to get treeId>>

Request Parameters (Body)¶

Name	Mandatory/Optional	Data Type	Description
filter	Optional	Filter Struct	The query criteria. The relationship between all the queried criteria uses the “AND” logical operator, i.e. all relationships between all the queried criteria must be true for data to be returned. Only one out of the 4 relational query criteria (`isParentOfAssetId`, `isChildOfAssetId`, `isAncestorOfAssetId`, and `isDescendantOfAssetId`) is allowed. For more details, see Filter Struct.
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	String Array	Enables you to crop the data result set returned in the interface 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. How does projection crop the result set>>

Filter Struct ¶

Note

isParentOfAssetId, isChildOfAssetId, isAncestorOfAssetId, and isDescendantOfAssetId cannot be used concurrently. Only one can be used per query.

Name	Mandatory/Optional	Data Type	Description
assetIds	Optional	String Array	The asset ID. Provide multiple asset IDs if you want to query multiple assets. How to get assetId>>
nameLike	Optional	I18nSearchVo Struct	The asset Name. Supports fuzzy query. For more details, see I18nSearchVo Struct.
modelIds	Optional	String Array	The model ID. Provide multiple root model IDs if you want to query multiple models. How to get modelID>>
rootModelIds	Optional	String Array	The model ID of the root node. Provide multiple root model IDs if you want to query multiple root nodes.
isParentOfAssetId	Optional (See Note above)	String	The asset to be queried is the immediate parent node of the specified asset, and its value is the asset ID of the specified asset. How to use expression>>
isChildOfAssetId	Optional (See Note above)	String	The asset to be queried is the immediate child node of the specified asset, and its value is the asset ID of the specified asset. How to use expression>>
isAncestorOfAssetId	Optional (See Note above)	String	The asset to be queried is the ancestor node of the specified asset, and its value is the asset ID of the specified asset. How to use expression>>
isDescendantOfAssetId	Optional (See Note above)	String	The asset to be queried is the descendant node of the specified asset, and its value is the asset ID of the specified asset. How to use expression>>

I18nSearchVo Struct ¶

Name

Mandatory/Optional

Data Type

Description

locale

Optional

String

The locale language, currently supporting:

default (default)
zh_CN
en_US
jp_JP
es_ES

value

Optional

String

The corresponding asset name for the locale. If null, no data will be returned. If blank, the data under the specified locale will be returned.

Response Parameters¶

Name	Data Type	Description
data	Array of AssetVo Structs	For the definition of an AssetVo struct, see AssetVo Struct.

AssetVo Struct ¶

Name	Data Type	Description
assetId	String	The asset ID.
modelId	String	The model ID of this asset.
modelIdPath	String	The path of the model ID.
name	StringI18n	The asset’s name in its respective locale’s language. For more details on the structure and locales supported, see Internationalized name struct.
timezone	String	Timezone where the asset is located.
description	String	The description of the asset.
label	String	The type of asset. `0`: Device asset `1`: Logical asset
inValid	Boolean	`True`: Invalid nodes `False`: Valid nodes
attributes	Map	The attributes of the model which the asset belongs to. Key is the attribute ID, which is of String type. The Value type depends on the attribute defined in the model.
tags	Map	User-defined tags. The Key and Value are of String type. How to use tags>>
childAssetNodeCount	Integer	The number of child nodes. If `isParentOfAssetId`, `isChildOfAssetId`, `isAncestorOfAssetId`, and `isDescendantOfAssetId` are not used in the query, this will return a null value. Note: EnOS Edge does not support this parameter.

Error Codes¶

Code	Message	Description
99400	Invalid arguments	The request parameter is invalid. Check the request parameters.
99500	System error	Internal server error. Contact EnOS support.
