XMLHttpRequest in JS using setRequestHeader

[filipdns]

Hello,

I want to get data from webradio and original script is:

"use strict";

const axios = require("axios");
const qs = require("qs");
//const { log } = require("abr-log")("meta-Djam Radio");

module.exports = async function(exturl) {
	try {
		const req = await axios({
			method: 'POST',
			url: exturl,
			data : qs.stringify({
				origin: 'website'
			}),
			headers: {
				'Accept': 'application/json, text/javascript, */*; q=0.01',
				'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
		}});
		const parsedResult = req.data;
		const curTrack = parsedResult["tracks"]["0"];
		const picture = curTrack["pictures"][0];
		return { artist:curTrack["artist"], title:curTrack["title"], cover: picture };
	} catch (err) {
		return { error: err };
	}
}

I don't have axios in Qt then I try code below but it's returning "null":

function djamradio(url) {
    var res
    var xhr= new XMLHttpRequest()
xhr.open('POST', url)
xhr.setRequestHeader('Accept','application/json, text/javascript, */*; q=0.01')
xhr.setRequestHeader('Content-Type','application/x-www-form-urlencoded; charset=UTF-8')
xhr.onreadystatechange = function() {

        if (xhr.readyState === XMLHttpRequest.DONE) { // La constante DONE appartient à l'objet XMLHttpRequest, elle n'est pas globale
            var parsedResult = xhr.responseText;
            //var curTrack = parsedResult["tracks"]["0"];
            //title=curTrack["title"]
            console.log(parsedResult)

        }

    };
    xhr.send()
}

url is: https://www.djamradio.com/actions/infos.php

How can I make it work please?

thank you for your help

Hi,

I haven't used that class yet but following your original call, shouldn't you be sending some data ?

Something like xhr.send(qs.stringify({ origin: 'website'})) ?

@SGaist Hi SGaist, happy new year!!

May be but with xhr.send(qs.stringify({ origin: 'website'})) that mean I need
var qs = require("qs");
but I can not use require in .js in Qt becauce require is not defined message come on...

@SGaist
I try with JSON.stringify but result still empty

function djamradio(url) {
    var res
    var xhr= new XMLHttpRequest()
    xhr.open('POST', url)

    xhr.setRequestHeader('Accept','application/json, text/javascript, */*; q=0.01')
    xhr.setRequestHeader('Content-Type','application/x-www-form-urlencoded; charset=UTF-8')
    xhr.onreadystatechange = function() {

        if (xhr.readyState === XMLHttpRequest.DONE) { // La constante DONE appartient à l'objet XMLHttpRequest, elle n'est pas globale
            var parsedResult = xhr.responseText;
            //var curTrack = parsedResult["tracks"]["0"];
            //title=curTrack["title"]
            console.log(parsedResult)

        }

    };
    xhr.send(JSON.stringify({ origin: 'website'}))
}

Then I would check the difference in the request sent using a tool like Fiddler.

You have to check that the request was succesfull xhr.status == 200, probably the server answers you with an error and this is why you are getting xhr.responseText = null.

https://www.w3schools.com/xml/ajax_xmlhttprequest_send.asp

Inspect if you are getting an http error code in xhr.status and the number to get more info.
