processor: fire an email when a MID is switched on in sub production

Solution for when email sending is switched off in sub production but switching on a MID could target prod systems (e.g. LDAP), a web service call is made to invoke a prod processor to queue the notification from prod

using a processor call on prod

business rule - RUNS ON SUBPROD: send alert when MID server switched on in UAT - processor via glidehttpsrequest
----------
(function executeRule(current, previous /*null when async*/) {

//--double check that the environment is preprod
var instURL=gs.getProperty('glide.servlet.uri');
if (instURL.toLowerCase()=='https://preprod.service-now.com/'){
gs.eventQueue('.preprod.mid.switchedon', current,'','');

//--now, queue the event on prod also so the email can actually fire

try{
//--run the processor this way, so that the notification can be sent from production (business rule runs in preprod where notifications are switched off)
var url='https://<prod>.service-now.com/preprodmid.do?onoff=on';
var request=new GlideHTTPRequest(url);
request.setBasicAuth(gs.getProperty('<user>'), gs.getProperty('<pwd>'));
request.addHeader('Accept', 'application/json');
//request.addParameter('', '');
var response=request.get();
var httpStatus=response.getStatusCode();
gs.log('TESTRESP:' + httpStatus, 'preprodmid:processorcall-ON');
if (httpStatus!=200 && httpStatus!=201){
throw ('httpStatus error: ' + httpStatus);
}

}catch (ex){
gs.log(ex.toString(), 'preprodmid:processorcall');
}
}

})(current, previous);
