How to write data to application resource file?

Question

Qt

Hello toast people.
You want to write data to a file, preferably from JavaScript or QML.
I created something similar in JavaScript:

var xhr = new XMLHttpRequest();
        xhr.open("POST", localFileUrl, false);
        writeContent = JSON.stringify(writeContent);
        xhr.setRequestHeader('Content-type', 'application/json');
        xhr.setRequestHeader('Content-Length', writeContent.length);
        xhr.send(writeContent);
        console.log(xhr.status);

No errors, status returns "0". Recording, respectively, is not performed. The data is written to a file inside the project (eg qrc:/settings/localCache.json). How can you make this miracle work?
