Discussion: Get latest software version automatically

[mattiaskagstrom]

I made a PHP script that fetches the latest version from the unify download site.
(Related to #151 )

<?php
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://www.ui.com/download/?group=unifi-ap');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');

curl_setopt($ch, CURLOPT_ENCODING, 'gzip, deflate');

$headers = array();
$headers[] = 'Authority: www.ui.com';
$headers[] = 'Pragma: no-cache';
$headers[] = 'Cache-Control: no-cache';
$headers[] = 'Accept: application/json, text/javascript, */*; q=0.01';
$headers[] = 'X-Requested-With: XMLHttpRequest';
$headers[] = 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.87 Safari/537.36';
$headers[] = 'Sec-Fetch-Site: same-origin';
$headers[] = 'Sec-Fetch-Mode: cors';
$headers[] = 'Referer: https://www.ui.com/download/unifi/unifi-ap';
$headers[] = 'Accept-Encoding: gzip, deflate, br';
$headers[] = 'Accept-Language: en-US,en;q=0.9,sv-SE;q=0.8,sv;q=0.7,en-SE;q=0.6,en-GB;q=0.5';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}

$workingvar = json_decode($result, true)["downloads"];
$workingvar = array_filter($workingvar, function ($node){
	return $node["category__slug"] == "software";
});
$workingvar = array_filter($workingvar, function ($node){
	return strpos($node["description"],"inux") !== false;
});
usort($workingvar, function ($item1, $item2) {
    return str_replace(".", "", $item2['version']) <=> str_replace(".", "", $item1['version']);
});
$latest = $workingvar[0];

$latest = $latest["version"];
curl_close($ch);
var_dump($latest);
?>

it currently outputs the versionnumber, but the object has multiple properties you could output.

not needed if #141 is completed

Made an extremely minor improvement to #141, opened a PR for it - #294

@the-wondersmith Note that if the controller is already installed and the admin account is registered for EA releases, you can pull their API bearer token from the Mongo DB and use that to download EA releases.

I have all but abandoned this project, but here is a link showing you how I'm using it:
