This example demonstrates how to send an image attachment to a requesting user as a binary stream.

JavaScript

/** *  Sample Scripted REST Resource that returns a stream of binary representing an attachment *  This sample uses ServiceNow JavaScript API GlideSysAttachmentInputStream to get an attachment as a stream then *  users WriteStream to stream the response. */(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {    var hdrs = {},        attachment_sys_id = '1852fd52471321009db4b5b08b9a71a9';
    hdrs['Content-Type'] = 'image/jpeg';    response.setStatus(200);    response.setHeaders(hdrs);
    var writer = response.getStreamWriter();    var attachmentStream = new GlideSysAttachmentInputStream(attachment_sys_id);    writer.writeStream(attachmentStream);})(request, response);

A request to this resource returns the following response.
