Quick Script: Check a ServiceNow Instance Build Tag
Enable AI Animation
I needed a quick way to check what build a ServiceNow instance was running. Here is the Node.js script I put together.
The script
module.exports = {
getBuildTag: function(instance){
return getBuildTag(instance);
},
test: function(instance){
return getBuildTag(instance)
}
};
function getBuildTag(instance) {
var returnStr;
if (instance) {
var https = require('https');
var url = require('url');
var address = 'https://' + instance + '.service-now.com/InstanceInfo.do?SOAP';
var options = { host: urlObj.host, path: urlObj.path, method: 'POST' };
var req = https.request(options, function (response) {
var body = [];
response.on('data', function (data) { body.push(data); });
response.on('end', function () {
body = body.toString();
if (body.indexOf('<html>') === -1) {
returnStr = body.split('<build_tag>')[1].split('</')[0];
} else {
returnStr = 'Not an instance';
}
});
});
req.on('error', function (e) { console.error(e); });
req.end();
} else {
returnStr = 'Needs an argument for an instance name';
}
return returnStr;
}Usage
var info = require('instance-info');
info.getBuildTag('myinstance');It sends a SOAP request to the InstanceInfo endpoint and parses the build_tag element from the response.
