Convert Attachment to base64 encoded content and vice versa

[Reena Kumari3]

 Hi Team,

My first requirement is to get the attachment in base64encoded content, I just achieved this with the below script and output  is also given below:-

var tableName = 'incident';
var recordID = 'ca644b5997261110e8fe39000153af00';
gs.print(getAttachmentContentsAsString(tableName, recordID));
function getAttachmentContentsAsString(tableName, recordID) {
	var gsa = new GlideSysAttachment();
	var bytesInFile = gsa.getBytes(tableName, recordID);
	var base64string = GlideStringUtil.base64Encode(bytesInFile);
	gs.info('Attachment content base64 encoded: ' +base64string);
}

My Second requirement is to convert base64 content to an attachment and  linked to an incident .

This is what I did for a PDF attachment

function setPDF(item){
		
		if(item == ''){
			return '';
		}
		
   var gr = new GlideRecord('sys_attachment');
   gr.addQuery('table_sys_id',item);
   gr.query();
		
		if(gr.next()){
			var sa = new GlideSysAttachment();
			var binData = sa.getContentBase64(gr);
			return binData;
			
		}
		
	}
