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. If not specified, only the first page with 100 records will be returned. The maximum records per page is 1000. `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. For more details, see How does projection crop the result set>>

Filter Struct ¶

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	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	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	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	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>>
