I'm trying to get data from a website that does not have an API documentation. I used selenium to login and navigate. Today I found the data I need, it appears after a post request.
There's any way I can get the exact post parameters to do it in my node program?

I'm having a problem with selectors on node, just rebember that I'm not conected with the site, I'm simulating a navigation with selenium. All the frameworks I checked to help me with selectors needed that I provide an url, but I can't, the only way I found to enter the system is from selenium navigation to simulating a real user.
I'm trying to get the quantity of for example: DragonBall, it would return x3 or Featured it would return x2 etc, however I have tried this method with just the spammed response of 2

I want to calculate the working hours, my scenario is, when user login to the app and clicks on time in button that time will be stored in the database (I am using mongodb) and if user logout and then login again and then time in button should display the time at which user did last time, and then if user clicks on time out button then it should calculate the working hours, for example, if user time in at 9:10:35 AM and time out at 5:50:47 PM then the total working hours should be 9:40:13 , but from my logic of calculating total working hours it give me this 4:40:12.
Here is my code:
totalWorkingHours() {

if(workinghours=="0" && getapitimeout==""){
print("11");
timeInHoursSplit = defaultIn.split(' '); //18:35:00 PM
timeOutHoursSplit = defaultOut.split(' ');

else if (workinghours == "0" && getTimeInStatus == true) {
print("12");

Kindly please help how I can do this.
I'm trying to verify a document from QLDB using nodejs. I have been following the Java verification example as much as I can, but I'm unable to calculate the same digest as stored on the ledger.
This is the code I have come up with. I query the proof and block hash from QLDB and then try to calculate digest in the same way as in Java example. But after concatinating the two hashes and calculating the new hash from the result I get the wrong output from crypto.createHash('sha256').update(c).digest("base64"). I have also tried using "base64" instead of "hex" with different, but also wrong result.
const rBlock = makeReader(res.Revision.IonText);
var block = [];
rBlock.next();
rBlock.stepIn();
rBlock.next();
while (rBlock.next() != null) {
if (rBlock.fieldName() == 'hash') {
block.push(Buffer.from(rBlock.byteValue()).toString('hex'));
}
}
console.log(block);
var proof = [];
const rProof = makeReader(res.Proof.IonText);
rProof.next();
rProof.stepIn();
while (rProof.next() != null) {
proof.push(Buffer.from(rProof.byteValue()).toString('hex'));
}
var ph = block[0];
var c;
for (var i = 0; i < proof.length; i++) {
console.log(proof[i])
for (var j = 0; j < ph.length; j++) {
if (parseInt(ph[j]) > parseInt(proof[i][j])){
c = ph + proof[i];
break;
}
if (parseInt(ph[j]) < parseInt(proof[i][j])){
c = proof[i] + ph;
break;
}
}
ph = crypto.createHash('sha256').update(c).digest("hex");
console.log(ph);
console.log();
}
I have figure it out. The problem was that I was converting the blobs to hex strings and hash them instead of the raw values. For anyone wanting to verify data in node, here is the bare solution:
ledgerInfo.getRevision(params).then(res => {
console.log(res);
const rBlock = makeReader(res.Revision.IonText);
var ph;
rBlock.next();
rBlock.stepIn();
rBlock.next();
while (rBlock.next() != null) {
if (rBlock.fieldName() == 'hash') {
ph = rBlock.byteValue()
}
}
var proof = [];
const rProof = makeReader(res.Proof.IonText);
rProof.next();
rProof.stepIn();
while (rProof.next() != null) {
proof.push(rProof.byteValue());
}
for (var i = 0; i < proof.length; i++) {
var c;
if (hashComparator(ph, proof[i]) < 0) {
c = concatTypedArrays(ph, proof[i]);
}
else {
c = concatTypedArrays(proof[i], ph);
}
var buff = crypto.createHash('sha256').update(c).digest("hex");
ph = Uint8Array.from(Buffer.from(buff, 'hex'));
}
console.log(Buffer.from(ph).toString('base64'));
}).catch(err => {
console.log(err, err.stack)
});
function concatTypedArrays(a, b) {
var c = new (a.constructor)(a.length + b.length);
c.set(a, 0);
c.set(b, a.length);
return c;
}
function hashComparator(h1, h2) {
for (var i = h1.length - 1; i >= 0; i--) {
var diff = (h1[i]<<24>>24) - (h2[i]<<24>>24);
if (diff != 0)
return diff;
}
return 0;
}
How to get the headers of the given Excel file in node xlsx (https://www.npmjs.com/package/xlsx) module?
Did the following in xlsx v0.16.9
const workbookHeaders = xlsx.readFile(filePath, { sheetRows: 1 });
const columnsArray = xlsx.utils.sheet_to_json(workbookHeaders.Sheets[sheetName], { header: 1 })[0];
As I could find, there's no exposed method to get headers of the Excel file from the module. So I copied few functions (With all respect to author. https://github.com/SheetJS/js-xlsx) from their source code and make that work with few changes.
function getHeaders(sheet){
var header=0, offset = 1;
var hdr=[];
var o = {};
if (sheet == null || sheet["!ref"] == null) return [];
var range = o.range !== undefined ? o.range : sheet["!ref"];
var r;
if (o.header === 1) header = 1;
else if (o.header === "A") header = 2;
else if (Array.isArray(o.header)) header = 3;
switch (typeof range) {
case 'string':
r = safe_decode_range(range);
break;
case 'number':
r = safe_decode_range(sheet["!ref"]);
r.s.r = range;
break;
default:
r = range;
}
if (header > 0) offset = 0;
var rr = XLSX.utils.encode_row(r.s.r);
var cols = new Array(r.e.c - r.s.c + 1);
for (var C = r.s.c; C <= r.e.c; ++C) {
cols[C] = XLSX.utils.encode_col(C);
var val = sheet[cols[C] + rr];
switch (header) {
case 1:
hdr.push(C);
break;
case 2:
hdr.push(cols[C]);
break;
case 3:
hdr.push(o.header[C - r.s.c]);
break;
default:
if (val === undefined) continue;
hdr.push(XLSX.utils.format_cell(val));
}
}
return hdr;
}
function safe_decode_range(range) {
var o = {s:{c:0,r:0},e:{c:0,r:0}};
var idx = 0, i = 0, cc = 0;
var len = range.length;
for(idx = 0; i < len; ++i) {
if((cc=range.charCodeAt(i)-64) < 1 || cc > 26) break;
idx = 26*idx + cc;
}
o.s.c = --idx;
for(idx = 0; i < len; ++i) {
if((cc=range.charCodeAt(i)-48) < 0 || cc > 9) break;
idx = 10*idx + cc;
}
o.s.r = --idx;
if(i === len || range.charCodeAt(++i) === 58) { o.e.c=o.s.c; o.e.r=o.s.r; return o; }
for(idx = 0; i != len; ++i) {
if((cc=range.charCodeAt(i)-64) < 1 || cc > 26) break;
idx = 26*idx + cc;
}
o.e.c = --idx;
for(idx = 0; i != len; ++i) {
if((cc=range.charCodeAt(i)-48) < 0 || cc > 9) break;
idx = 10*idx + cc;
}
o.e.r = --idx;
return o;
}
Call getHeaders function by passing the Work Sheet will return the headers array of the excel sheet.
Have a look here:
https://www.npmjs.com/package/xlsx if we go through the documentation. It says that we need to pass options By default, sheet_to_json scans the first row and uses the values as headers. With the header: 1 option, the function exports an array of arrays of values.
So the whole code goes like this:
const data = e.target.result;
const workbook = XLSX.read(data, { type: "array" });
console.log(workbook);
const firstSheetName = workbook.SheetNames[0];
const worksheet = workbook.Sheets[firstSheetName];
const options = { header: 1 };
const sheetData2 = XLSX.utils.sheet_to_json(worksheet, options);
const header = sheetData2.shift();
console.log(header); //you should get your header right here
Where e.target comes from your input.
