RESTMessageV2 - setQueryParameter, size limit

[PhoenixMing0912]

Hi experts,

I have coded a very simple RESTful post and run it in Scripts-Background.

var request = new sn_ws.RESTMessageV2('RemoteServer','Post');

request.setQueryParameter("strBase64", strBase64);

I am trying to send String "strBase64" which is Base64 encoding of an attachment.

However, looks like it has a size limitation, only a couple of KB is allowed to send.

I am quite sure that it is a service now side problem because I have also tried a Java client call and it worked.

Can anyone help?

First, I would get the attachment content from sys id.

var gr = new GlideRecord("sys_attachment");
gr.addQuery("sys_id", '85b034c1dbe6e3403aff6a494896199b');
gr.query();
if (gr.next()){
var gsa = new GlideSysAttachment();
var binData = gsa.getBytes(gr);
var strBase64 = GlideStringUtil.base64Encode(binData);
}

I tried to send "strBase64" as request query parameter but if it was big(e.g., 200KB+), I would got an error and return http status with 400.

if i am not wrong you want to send the attachment to other tool .

if yes have you tried to use "setRequestBodyFromAttachment()" .

Doc Link below
