POST timeseries (2017.02)

Write timeseries data to the FEWS system using the timeseries sets defined by the filters. The timeSeries are stored in the piTimeSeriesXmlContent.

The 'convertDatum' argument is to allow timeseries that support a datum to have their values converted to a value relative to the location height. If values are already relative to location then enter FALSE or omit.

If no filterId is used, all timeseries will be accepted that are configured in the default filter. To only allow specific timeSeries to be imported, use a filterId. 

N.B.: by default POST operations are disabled in the Delft-FEWS WebServices and have to be explicitly enabled by setting the READONLY_MODE to false in the FewsPiService.properties. See also: FEWS Web Services configuration FewsPiService.properties.

Request parameters

• filterId (string): Filter id for when the input timeseries maps to multiple internal timeseries. Within the scope of the filter the input timeseries should only map to one internal timeseries.

• convertDatum (boolean): Convert values from relative location height to absolute height values

Body parameters

• piTimeSeriesXmlContent (xml string, required): PiTimeseries xml file  encoded in the 'application/x-www-form-urlencoded Content-Type. Example of a piTimeSeriesXmlContent (unencoded):

  Since 2018.02 the service also supports milliseconds. The parser automatically recognises which format is used.

• N.B. The SOAP Web Service has support for posting timeSeries as binary data using the piTimeSeriesBinaryContent. This is NOT support in this REST service of the PI Service.

Response

• Diag PI xml response with all diagnostic output.

Example request

The following example shows how timeSeries can created using the POST method. Take note that the TimeSeries have to be posted in PI XML Format in the body of the POST request using the piTimeSeriesXmlContent key. The value is the content of the PI XML Timeseries in application/x-www-form-urlencoded format.

Example code

To post timeSeries to the Delft-FEWS WebServices, the following is example JAVA code:

String piTimeSeries = "PI XML Content";
URL url = new URL("http://localhost:8080/FewsWebServices/rest/fewspiservice/v1/timeseries");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
connection.setRequestProperty("charset", "utf-8");
String postData = "piTimeSeriesXmlContent=" + URLEncoder.encode(piTimeSeries, StandardCharsets.UTF_8);
connection.setRequestProperty("Content-Length", Integer.toString(postData.length()));
connection.setUseCaches(false);
try (DataOutputStream wr = new DataOutputStream(connection.getOutputStream())) {
    wr.write(postData.getBytes());
