You need a server to receive the data and save it to the disk.
You could use something like the tutorial you followed.
The only thing that needs to be changed is that the php server should write the contents of your post request to the disk. Something like the script below
I did not test this, so probably some changed need to be made.
<?php
//http://stackoverflow.com/questions/18382740/cors-not-working-php
if (isset($_SERVER['HTTP_ORIGIN'])) {
header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Max-Age: 86400'); // cache for 1 day
}
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
exit(0);
}

$postdata = file_get_contents("php://input");
if (isset($postdata)) {
$request = json_decode($postdata);
$myfile = fopen("newfile.json", "w") or die("Unable to open file!");
fwrite($myfile, $request);
fclose($myfile);
}
else {
echo "Not called properly!";
}
?>
