Hi @Lucas Romani1 ,
You can use the GlideStringUtil.base64Encode() method to convert the binary file to Base64 in ServiceNow. Here's an updated version of the code using GlideStringUtil.base64Encode():
var rest = new sn_ws.RESTMessageV2();
rest.setEndpoint('https://xxxxxxxxxx.service-now.com/api/now/attachment/6f20c5fe1bbe6d10e641eb5be54212/file');
rest.setHttpMethod('get');
rest.setRequestHeader("Accept", '*/*');
rest.setBasicAuth("user", "password");
var response = rest.execute();
var obj = response.getBody(); // obj is the binary representation of the attachment
var base64String = GlideStringUtil.base64Encode(obj);
gs.info(base64String); // base64String is the Base64 representation of the binary file
For converting large files to base64encode string, you can refer below script:
var StringUtil = new GlideStringUtil();
var gsis = GlideSysAttachmentInputStream(gr.sys_id.toString());
var ba = new Packages.java.io.ByteArrayOutputStream();
gsis.writeTo(ba);
baos.close();
var base64EncodedData = StringUtil.base64Encode(ba.toByteArray());
