PHP - getJanusToken

General
1

Dear all,

I’m writing the function to generate Janus Token in PHP language based the code written for NodeJS that posted in this document
https://janus.conf.meetecho.com/docs/auth

Below is my code:

function getJanusToken($secret, $data = [], $timeout = 24 * 60 * 60) {
    $realm = 'janus';
    //$expiry = Math.floor(Date.now() / 1000) + timeout;
    $expiry = time() + $timeout;
    
    //$strdata = [expiry.toString(), realm, ...data].join(',');
    $data = array_merge([$expiry, $realm], $data);
    $strdata = implode(',', $data);
    
    //const hmac = crypto.createHmac('sha1', secret);
//    hmac.setEncoding('base64');
//    hmac.write(strdata);
//    hmac.end();
    
    $hmac = base64_encode(hash_hmac('sha1', $strdata, $secret));
    
    //return [strdata, hmac.read()].join(':');
    //<timestamp>,janus,<plugin1>[,plugin2...]:<signature>
    return implode(':', [$strdata, $hmac]);
};

//const token = getJanusToken('janus', ['janus.plugin.videoroom']);

$tokenSecret = 'janus-token';
$token = getJanusToken($tokenSecret, ['janus.plugin.videoroom']);
var_dump($token);

But the token generated by this function was invalid.

Does anyone know what is the incorrect code line, and please help me to correct it.

Thanks,
Thanh Nguyen

Please ignore this topic.
I resolved this issue.

I used “Stored Tokens” replace for “HMAC-signed token”.
