ServiceNow - Change a file name in Midserver

I am currently trying to replace the name of a file in the Mid Server after a scheduled export.
The idea here is that the file goes with the name in the format "file_name_datetime" and the customer needs "datetime_file_name" for the file to be correctly read by another system.
My main idea was to rename the file after the export to the correct format, but if there is a way of changing the file name to the required one I could do that also.
I would love to hear from you guys as I have no idea how can I do this.
Thanks in advance.

If anyone is interested in the answer, see below:
Script include:
initialize: function() {
this.filePath = gs.getProperty('directory_path');
this.midServer = gs.getProperty('midserver');
this.authMidServerBase64 = gs.getProperty('authmidserver');
},
nameChange: function(exportSetName) {
var exportGr = new GlideRecord("sys_export_set_run");
exportGr.addEncodedQuery("set.nameSTARTSWITH" + exportSetName);
exportGr.orderByDesc("completed");
exportGr.query();
if (exportGr.next()) {
var attachSysID = exportGr.ecc_agent_attachment.sys_id;
}
var attachGr = new GlideRecord("sys_attachment");
attachGr.addEncodedQuery("table_sys_idSTARTSWITH" + attachSysID);
attachGr.query();
if (attachGr.next()) {
var attachName = attachGr.file_name;
var attachDate = attachName.match((/\d+/));
var newName = attachDate + '_' + exportSetName + '.csv';
}
var jspr = new JavascriptProbe(this.midServer);
jspr.setName('FileNameChange'); // This can be any name
jspr.setJavascript('var ddr = new MidServer_script_include(); res = ddr.execute();');
jspr.addParameter("verbose", "true");
jspr.addParameter("skip_sensor", "true"); // prevent Discovery sensors running for the ECC input
jspr.addParameter("filename", this.filePath + "\\" + attachName);
jspr.addParameter("filePath", this.filePath);
jspr.addParameter("newName", this.filePath + "\\" + newName);
jspr.addParameter("operation", "rename");
return jspr.create();
},

I want to make a private chat for every user since all the user's chat are showing in a same view

I'm trying to make a chat application using spring boot and I am stuck. This is my Frontend (custom.js) code. I want to make a separate chat view for every specific user since all user's chat which is entered in this are showing on the same view.

NodeJS SQL Server - Running multiple queries with Async

I'm attempting to run two separate queries in a NodeJS Lambda Function. The first inserts a single record, and will return an order number used in the subsequent queries. The second query needs to insert n records (order items), so I've been trying to execute those utilizing the async node library as you can see below.
I'm running into issues where it's either not executing those queries at all, or is only inserting a single record versus n records. I'm feeding it right now with an API request, so the referenced items array should have two indexes in it, resulting in two iterations.
const sql = require('mssql');
const async = require('async');
(function() {
// ——- Database support ——- //
exports.handler = function(event, context, callback)
{
const config = {
user: 'my_user',
password: 'my_pass',
server: 'my_serv',
database: 'my_db',
options: {
encrypt: true
}
};
// Request Body
var body = event;
var items = body[1]["items"];
var addDateTimeRaw = body[1]["created_at"];
var splitDateTime = addDateTimeRaw.split(" ");
// SPROC params
var CustomerNumber = "1234";
var OrderDateString = splitDateTime[0];
var ShipVia = "UPS";
var FOB = "null";
var PaymentTerms = "CREDIT CARD";
var Discount = "0";
var OrderAmount = body[1]["total_price"].cents;
var PONumber = body[1]["_id"];
var Comment = "I am a comment";
var SalesPerson = "WA";
var IsShippingSameAsBilling = "X";
var TaxableAmount = body[1]["total_value"].cents;
var TaxState = "my_state";
var AddDate = splitDateTime[0];
var AddTime = splitDateTime[1];
var WebOrderNumber = body[1]["_id"];
sql.connect(config, (err) => {
if (err) {
console.log(err);
callback(err);
} else {
const req = new sql.Request();
req.query('EXEC InsertOrder #CustomerNumber = "' + CustomerNumber + '", #OrderDateString = "' + OrderDateString + '", #ShipVia = "' + ShipVia + '", #FOB = "' + FOB + '", #PaymentTerms = "' + PaymentTerms + '", #Discount = "' + Discount + '", #OrderAmount = "' + OrderAmount + '", #PONumber = "' + PONumber + '", #Comment = "' + Comment + '", #SalesPerson = "' + SalesPerson + '", #IsShippingSameAsBilling = "' + IsShippingSameAsBilling + '", #TaxableAmount = "' + TaxableAmount + '", #TaxState = "' +TaxState + '", #AddDate = "' + AddDate + '", #AddTime = "' + AddTime + '", #WebOrderNumber = "' + WebOrderNumber + '";', (error, result) => {
if (error) {
console.log(error);
callback(error);
} else {
var OrderNumber = result.recordset[0].sono;
insertOrderItems(OrderNumber);
sql.close();
context.succeed(result.recordset)
return JSON.stringify(items);
}
});
function insertOrderItems(OrderNumber) {
async.forEachOf(items, function (item, i, inner_callback){
//var itemNumber = item["sku"];
var ItemNumber = "5678";
var DiscountPercent = "0";
var TaxRate = "6";
var Quantity = item["quantity"];
var ItemSequence = i + 1;
var CustomerMemo = "I am a memo";
var UnitPrice = "6.00";
var ssql = 'EXEC InsertOrderItems #OrderNumber = "' + OrderNumber + '", #ItemNumber = "' + ItemNumber + '", #DiscountPercent = "' + DiscountPercent + '", #TaxRate = "' + TaxRate + '", #Quantity = "' + Quantity + '", #ItemSequence = "' + ItemSequence + '", #CustomerMemo = "' + CustomerMemo + '", #UnitPrice = "' + UnitPrice + '";';
req.query(ssql, function(err, members, fields){
if(!err){
console.log(members);
//context.succeed(members.recordset)
inner_callback(null);
} else {
console.log("Error while performing Query");
inner_callback(err);
};
});
}, function(err){
if(err){
//handle the error if the query throws an error
callback(err);
}else{
//whatever you wanna do after all the iterations are done
callback(null);
}
});
}
}
});
sql.on('error', (err) => {
console.log(err);
callback(err);
});
};
}());
Why might that function call to the async SQL query not be executing? I'm attempting to keep the same SQL connection open for both of the executed queries.

The async is not a main issue. I patched some places but it still worse.
Why do you not learn step-by-step?
const sql = require('mssql');
const async = require('async');
const config = { ... };
exports.handler = function(event, context, callback) {
// Use default object with props or check existing of every props
var body = (event && event[1]) instanceof Object ? event[1] : {items: [], created_at: ' ', _id: ...};
var items = body.items || []; // Always use default value
var [addDate, addTime] = (created_at || '').split(' '); // Use destructuring assignment
// SPROC params
var CustomerNumber = "1234";
var OrderDateString = splitDateTime[0];
var ShipVia = "UPS";
var FOB = "null";
var PaymentTerms = "CREDIT CARD";
var Discount = "0";
var OrderAmount = parseFloat((body.total_price || {}).cents) || 0; // total_price can be non-object and it'll fall your app
var PONumber = body[1]["_id"];
var Comment = "I am a comment";
var SalesPerson = "WA";
var IsShippingSameAsBilling = "X";
var TaxableAmount = body[1]["total_value"].cents;
var TaxState = "my_state";
var WebOrderNumber = body._id;
sql.connect(config, (err) => {
// Early quit to avoid {}-ladder
if (err)
return callback(err);
const req = new sql.Request();
// Never do like this. Read about sql-injection. Use placeholders.
req.query('EXEC ost_InsertOrder #CustomerNumber = "' + ..., (err, result) => {
if (err)
return callback(err);
var OrderNumber = result.recordset.length && result.recordset[0].sono; // You must be sure that result has rows
// You should read about async-code
insertOrderItems(OrderNumber); // Here you start to insert items
sql.close(); // But before it'll success you close connection.
context.succeed(result.recordset);
// I didn't see definition of items.
// Return? For what?
return JSON.stringify(items);
});
...
}
});
sql.on('error', callback);
};

capturing all dom manipulation events

I'm trying to create a proxy JS so every request to external resource will be proxied like XHR or any other resource.
so for XHR request i manage to do it with this code:
if(window.XMLHttpRequest)
{
var XMLHttpRequest = window.XMLHttpRequest;
var startTracing = function () {
XMLHttpRequest.prototype.uniqueID = function() {
// each XMLHttpRequest gets assigned a unique ID and memorizes it
// in the "uniqueIDMemo" property
if (!this.uniqueIDMemo) {
this.uniqueIDMemo = Math.floor(Math.random() * 1000);
}
return this.uniqueIDMemo;
}
// backup original "open" function reference
XMLHttpRequest.prototype.oldOpen = XMLHttpRequest.prototype.open;
var newOpen = function(method, url, async, user, password) {
//console.log(url);//new
if (url.includes("somesample")) {
//Debug Only
/*console.log("[" + this.uniqueID() + "] intercepted open (" +
method + " , " +
url + " , " +
async + " , " +
user + " , " +
password + ")");*/
urlParts = /^(?:\w+\:\/\/)?([^\/]+)(.*)$/.exec(url);
hostname = urlParts[1]; // www.example.com
path = urlParts[2]; // /path/to/somwhere
proxyprefix = "http://myproxy.com/xhr.php?url="
fullurl = "http://" + hostname + path;
rewrittenUrl = proxyprefix + btoa(encodeURIComponent(fullurl));
url = rewrittenUrl;
}
this.oldOpen(method, url, async, user, password);
}
XMLHttpRequest.prototype.open = newOpen;
// backup original "send" function reference
XMLHttpRequest.prototype.oldSend = XMLHttpRequest.prototype.send;
var newSend = function(a) {
//console.log("[" + this.uniqueID() + "] intercepted send (" + a + ")");
var xhr = this;
var onload = function() {
/*console.log("[" + xhr.uniqueID() + "] intercepted load: " +
xhr.status +
" " + xhr.responseText);*/
};
var onerror = function() {
/* console.log("[" + xhr.uniqueID() + "] intercepted error: " +
xhr.status);*/
};
xhr.addEventListener("load", onload, false);
xhr.addEventListener("error", onerror, false);
this.oldSend(a);
}
XMLHttpRequest.prototype.send = newSend;
}
startTracing();
}
else if (window.ActiveXObject) {
var ActualActiveXObject = ActiveXObject;
var ActiveXObject = function(progid) {
var ax = new ActualActiveXObject(progid);
if (progid.toLowerCase() == "msxml2.xmlhttp") {
var o = {
_ax: ax,
_status: "fake",
responseText: "",
responseXml: null,
readyState: 0,
status: 0,
statusText: 0,
onReadyStateChange: null
};
o._onReadyStateChange = function() {
var self = o;
return function() {
self.readyState = self._ax.readyState;
if (self.readyState == 4) {
self.responseText = self._ax.responseText;
self.responseXml = self._ax.responseXml;
self.status = self._ax.status;
self.statusText = self._ax.statusText;
}
if (self.onReadyStateChange) self.onReadyStateChange();
}
}();
o.open = function(bstrMethod, bstrUrl, varAsync, bstrUser, bstrPassword) {
/*console.log("intercepted open (" +
bstrMethod + " , " +
bstrUrl + " , " +
varAsync + " , " +

bstrPassword + ")");*/
varAsync = (varAsync !== false);
this._ax.onReadyStateChange = this._onReadyStateChange
return this._ax.open(bstrMethod, bstrUrl, varAsync, bstrUser, bstrPassword);
};
o.send = function(varBody) {
return this._ax.send(varBody);
};
}
else
var o = ax;
return o;
}
}
and its working fine.
and because i have got some js that manipulate the dom and adds elements i need to intercept that to.
so i started by rewriting appendChild with that code:
window.callbackFunc = function(elem, args) {
//console.log(elem);
for (var key in elem) {
if (elem.hasOwnProperty(key) && elem[key].src)
{
elem[key].src = "http://myptoxy/proxy.php?u=" +encodeURIComponent(elem[key].src);
}
}
}
window.f = Element.prototype.appendChild;
Element.prototype.appendChild = function() {
window.callbackFunc.call(this, arguments);
return window.f.apply(this, arguments);
};
and thats also working well but i encounter a problem with createlement.
some js code on my site creates an iframe with src that i'm unable to intercept with this code:
document.createElement = function(create) {
return function() {
var ret = create.apply(this, arguments);
//console.log(ret);
for (var key in ret) {
if (ret.hasOwnProperty(key) && ret[key].src) {
ret[key].src = "http://myproxy.com/proxy.php?u=" + encodeURIComponent(elem[key].src);
}
}
return ret;
};
}(document.createElement)
I mean I can intercept the creation but the attributes are empty obviously the script adds the attribute after the element creation)
I tried to use MutationObserver but with no luck...
Any help?
Another approach to the entire problem will be great!

nodejs, function jumping to a completely unrelated line for no reason?

So I'm trying to add a command to an already existing project InsomBot to retrieve a League of Legends player's information, I am using lol-api found on npm for this, the only modifications made to this package were to update the API url's as they were outdated and incorrect, my code is below and an image of the issue in a debugger is also below, once the program reaches line 105 it jumps to line 111 for seemingly no reason, perhaps I'm missing a simple indentation error here or I'm not closing something properly, etc. Any help would be appreciated.

Line 105 = api.summonerByName(term, 'na', function(results){
Line 111 = var defIndex = message.indexOf(def);

Line 111 contains the next statement after line 105, so it makes perfect sense.
api.summonerByName() is an asynchronous method, so its callback (lines 106 and 107) will be called only when there are results available, but the rest of your program will continue to run.
