Question

I am trying to use a feedback.php file to remove inactive devices from my database.
I have the script working for now code:

echo "<br/>Started processing Feedback";

ini_set( 'display_errors','1'); 

//get the certificates
$certificates = DataService::singleton()->getCertificates();

foreach ($certificates as $certificate) {

    //only process apps that have a certificate associated to it.
    if($certificate->KeyCertFile == ''){

        echo "<br/>Certfile not set for App: [{$certificate->CertificateName}]";
        continue;
    }
    //var_dump($certificate);
    //connect to feedback server
    $certificatePath = $certificateFolder . '/' . $certificate->KeyCertFile;

    $server = DataService::singleton()->getCertificateServer($certificate->CertificateId, 3);
    $apns = new apns('feedback.sandbox.push.apple.com:2196', $certificatePath, $certificate->Passphrase);


    //get tokens
    $feedbackTokens = $apns->getFeedbackTokens();

    //close connection
    unset($apns);

    //print the number of tokens to check for
    $countTotal = count($feedbackTokens);
    echo "<br/>There are [{$countTotal}] tokens notified by feedback";

    //loop trough the tokens
    foreach ($feedbackTokens as $feedbackToken) {

        //only DeActivate devices that where updated before they where removed. Otherwise the user could of installed the app again.
        DataService::singleton()->setDeviceInactive($feedbackToken['devtoken'], $app->AppId, $feedbackToken['timestamp']);
    }
}
echo "<br/>Completed processing Feedback";
?>

However I have a problem with connecting to the server. Delivering push notifications work fine but this feedback script doesn’t work.
It’s not using the certificate that I input this is what happens:

<br/>Started processing Feedback<br/>Opening connection to: feedback.sandbox.push.apple.com:2196<br/>Clossing connection to: feedback.sandbox.push.apple.com:2196<br/>There are [0] tokens notified by feedback<br/>Opening connection to: feedback.sandbox.push.apple.com:2196<br/>Clossing connection to: feedback.sandbox.push.apple.com:2196<br/>There are [0] tokens notified by feedback<br/>Completed processing Feedback

But, It replies 0 tokens. And when I just connect to a random host it shows the same:

<br/>Started processing Feedback<br/>Opening connection to: localhost:80<br/>Clossing connection to: localhost:80<br/>There are [0] tokens notified by feedback<br/>Opening connection to: localhost:80<br/>Clossing connection to: localhost:80<br/>There are [0] tokens notified by feedback<br/>Completed processing Feedback

Getting a reply takes a while to.
I guess this has something to do with the certificate if I am not mistaking or am I missing some sort of PHP include?

Answer 1

If I recall correctly from your earlier problem your $server variable was NULL. This implies to me that the real problem lies in the line

$server = DataService::singleton()->getCertificateServer($certificate->CertificateId, 3);

If everything was kosher with your certificate, this should have returned a valid server. But it didn’t – which you temporarily worked around by hard coding the $server variable in the next line:

$apns = new apns('feedback.sandbox.push.apple.com:2196', $certificatePath, $certificate->Passphrase);

In other words – you are right to suspect there is a problem with your certificate.

You might find the information given at this earlier answer useful to solve that issue.
