Get Asset Generic Data¶

Get the common data of a specified measurement point of a specified device within a certain period.

Operation Permissions¶

Required Authorization	Required Operation Permission
Asset	Read

Request Format¶

GET
https://{apigw-address}/tsdb-service/v2.0/generic?orgId={}&modelId={}&assetIds={}&measurepoints={}&startTime={}&endTime={}&pageSize={}&accessKey={}&localTimeAccuracy={}

Request Parameters (URI)¶

Name	Location (Path/Query)	Required or Not	Data Type	Description
orgId	Query	true	String	Organization ID which the asset belongs to. How to get orgId>>
modelId	Query	false	String	Model ID which the asset belongs to. How to get modelID>>
assetIds	Query	true	String	Asset ID, which supports querying multiple assets; multiple asset IDs are separated by commas. How to get assetId>>
measurepoints	Query	true	String	Asset measurement point. It is supported to query multiple measurement points, and all the measurement points are separated by commas; the upper limit for query is 3000 (Number of devices *Number of measurement points). How to get pointId>>
startTime	Query	true	String	Time of start sampling data, where UTC time format and local time format are supported. The local time format is YYYY-MM-DD HH:MM:SS. In case of local time format, the application queries the assets by the local time of the location where the device is. Timezone information is required for UTC time format, e.g. 2019-06-01T00:00:00+08:00; in case of UTC time format, the application queries all the assets by the unified start timestamp and end timestamp.
endTime	Query	true	String	Time of stop sampling data. Its format must be consistent with the start time
pageSize	Query	false	Integer	Upper limit of the returned records in a single page for a single measurement point of a single device, which is 1000 by default. For a single query, the total returned data amount follows the following constraints: (Number of devices * Number of points * pagesize) ≤ 640000.
accessKey	Query	false	String	Service account of the application. The application authenticates with `accessKey` to obtain the data that it is authorized to access. How to get accessKey>>
withQuality	Query	false	Boolean	Whether the quality indicator is included in the response, true means included, otherwise it is not included.
localTimeAccuracy	Query	false	Boolean	Specify whether query returns data with millisecond time stamp.

Response Parameters¶

Name	Data Type	Description
items	`List<Object>`	List of asset data. The data returned for a single point of a single device is sorted by time in ascending order. Parameters are stored in the Object struct. See items.

items¶
