Request Format¶

POST https://{apigw-address}/tsdb-service/v2.1/raw

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 organization ID>>

Request Parameters (Body)¶

Name	Mandatory/Optional	Data Type	Description
modelId	Optional	String	The model ID. How to get model ID>>
assetIds	Mandatory	String	The asset ID. Supports the query of multiple asset IDs, separated by commas. How to get asset ID>>
pointIds	Mandatory	String	The measurement point ID. Supports the query of multiple measurement point IDs, separated by commas. How to get measurement point ID>>
startTime	Mandatory	String	The start time of the sampling data, where both UTC and local time formats are supported. For UTC time format, the application will query all the asset data by the unified start timestamp and end timestamp. Timezone information is required for the UTC time format: 2019-06-01T00:00:00+08:00. For local time format, the application will query the asset data by the local time of where the device is located. Its format is: YYYY-MM-DD HH:MM:SS.
endTime	Mandatory	String	The end time of the sampling data. Its format must be consistent with `startTime`.
pageSize	Optional	Integer	The upper limit of the returned records in a single page for a single measurement point of a single device, which is 1,000 by default.
orderBy	Optional	String	Specify whether to sort the response result according to a certain field. Only the field timestamp is supported for now. timestamp asc (default): Sort result by ascending order timestamp desc: Sort result by descending order.
withQuality	Optional	Boolean	true = the quality indicator is included in the response false = the quality indicator is not included in the response
localTimeAccuracy	Optional	Boolean	true = query returns data with millisecond time stamp false (default) = query returns data without millisecond time stamp
localTimeFormat	Optional	Integer	Specify whether the local time value includes time zone information of devices. 0 (default): without time zone information; 1: with time zone information.
itemFormat	Optional	Integer	Specify the displaying format of the returned device data. Available options are 0, 1, and 2. For the example of each displaying format, see Item Format Example>>
boundaryType	Optional	String	Specify the type/scope of data to be queried if data is stored after compression. Available options are: `inside` (query compressed raw data only, default), `outside` (query compressed raw data and data records before the specified start time and after the end time), `interpolated` (query compressed raw data and interpolated data records at the specified start time and end time), and `sample` (return interpolated data records by specified time interval and algorithm within the specified start time and end time). The interpolated data can be used for making data in TSDB complete based on business needs.
interval	Optional	Integer	For `boundaryType=sample`, specify the time interval for generating the interpolated data records. The default value is 60, in seconds.
interpolation	Optional	String	For `boundaryType=sample`, specify the algorithm for generating the interpolated data records. Available options are: `linear` (linear interpolation, default), `previous` (previous value interpolation), `near` (near value interpolation), `after` (next value interpolation). For detailed information about the algorithm, see Data Interpolation Algorithm>>
type	Optional	String	Specify the TSDB storage type to query data from. Available options are: `ai` (query AI Raw Data only), `ai_normalized` (query AI Normalized Data only), `di` (query DI Data only), `pi` (query PI Data only), and `generic` (query Generic Data only). If not specified, query measurement point data from the AI Raw, DI, PI, and Generic storage by default.

Response Parameters¶

Name	Data Type	Description
data	List<JSONObject>	The list of asset data. The data returned for a single point of a single device is sorted by the data time stamp in ascending order. For more information, see items>> <get_asset_raw_data_by_time_range.html#items>.__

items¶

Sample¶

{
        "assetId": "yourAssetId",

}

Parameters¶

Name	Data Type	Description
assetId	String	The asset ID.
timestamp	Long	The data timestamp (UNIX time, accurate to the second).
pointId	Double	This parameter is a variable, representing the identifier and data of the measurement point.
