How to escape special characters

[surya123]

Hi All,

I am sending the json to 3rd party system. So using the BR i was forming it this way -

var r = new sn_ws.RESTMessageV2('Creation', 'Default PUT');

r.setStringParameterNoEscape('adhocID', current.number);
r.setStringParameterNoEscape('fieldid', current.field_id);
r.setStringParameterNoEscape('state', stateVal);
r.setStringParameterNoEscape('worknote', current.work_notes));
r.setStringParameterNoEscape('group', current.assignment_group.getDisplayValue());
r.setStringParameterNoEscape('closed', current.closed_at);
var response = r.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();

I get an error message as the "Record was misformed" when the worknote is typed as-

ASU, Test
testasu
CN=tyty\, fgt,OU=CGS Users,DC=tester,DC=cvs

I see the log as this -

"<>?,./;'[]=-1234567890-\ndfygdhgg\n\\bddmd\n//\n"

But i have already entered more worknotes and log of notes show all the added data. Not sure what is going wrong. This my entire scrpt

function jsonEncode(str) {
var parser = new JSONParser();
var parsed = parser.parse(str);
var json = new global.JSON().encode(parsed);
gs.log(" Test" + json);
return json;
}

(function executeRule(current, previous /*null when async*/) {

try {

var notes='';
var gr = new GlideRecord('sys_journal_field');
gr.addEncodedQuery("element=comments^ORelement=work_notes");
gr.addQuery('element_id',current.sys_id);
gr.orderByDesc('sys_created_on');
gr.query();
while(gr.next()){
notes +=((gr.sys_created_on.toString() + ' - ' + gr.sys_created_by.toString() + ' ' + gr.element.toString() + '- ' + gr.value.toString() + "<br>").replace(/\n/g, "\\n").replace(/\r/g, "\\r").replace(/\t/g, "\\t"));

}
//notes = notes.toString();
gs.addInfoMessage(notes);
var json = new JSON();
var r = new sn_ws.RESTMessageV2('Creation', 'Default PUT');
r.setStringParameter('ID', current.number);
r.setStringParameter('worknote',jsonEncode(notes));


var response = r.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();


}

Hi,

I will need to encode the string of worknotes and set that in string paramter right. I dont need to decode it?

[Mike Patel]

try changing below

notes +=(gr.sys_created_on + ' - ' + gr.sys_created_by + ' ' + gr.element + '- ' + gr.value + '\n');

and change

var json= new global.JSON();

json.encode(notes);

I believe the encoding simply converts the carriage returns (CR), line feeds (LF) into \r and \n. You don't need to decode them. The destination where they will be displayed (say a UI in a browser) should automatically decode and display them.
