Example 21 with StreamingOutput

use of javax.ws.rs.core.StreamingOutput in project ice by JBEI.

the class SampleResource method getRequestFile.

@POST
@Path("/requests/file")
@Produces(MediaType.APPLICATION_OCTET_STREAM)
public Response getRequestFile(@QueryParam("sid") String sid, final ArrayList<Long> requestIds) {
    // only supports csv for now
    if (StringUtils.isEmpty(sessionId))
        sessionId = sid;
    final String userId = getUserId(sessionId);
    final ArrayList<Long> sampleRequestIds = new ArrayList<>();
    for (final Number number : requestIds) {
        sampleRequestIds.add(number.longValue());
    }
    try {
        ByteArrayOutputStream outputStream = requestRetriever.generateCSVFile(userId, sampleRequestIds);
        StreamingOutput stream = outputStream::writeTo;
        return Response.ok(stream).header("Content-Disposition", "attachment;filename=\"data.csv\"").build();
    } catch (IOException e) {
        Logger.error(e);
        throw new WebApplicationException(Response.Status.INTERNAL_SERVER_ERROR);
    }
}
