How to use Apple Push Notifications if you can't use port 2195?

Question

I have developed a script using stream_socket_client() and it works on my localhost but when I try to use it online (with Fatcow.com web hosting) it won't work. I receive the following error:

Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Connection refused) in .../send-notification.php on line 18 Failed to connect 111 Connection refused

This is line 18:

$fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);

I know that the password for the .pem file is correct. The question becomes if I can't use this port what do I do? Is there any free service that I can use? I know that port 80 is open.

I've heard that using the curl() function will work but have been unsuccessful so far.

I would really appreciate getting pointed in the right direction.

Answer 1

In order to send the notifications to the device need to enable 2195 port in the firewall. For security reasons some organizations disabling these ports in the firewall. 2196 port is used for feedback services and this port also should open in the firewall. Without opening these ports messages cannot deliver to APNS.

Answer 2

I believe the following is what you are looking for

$url = 'https://gateway.sandbox.push.apple.com:2195';
$cert = 'AppCert.pem';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSLCERT, $cert);
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, "passphrase");
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"device_tokens": ["458e5939b2xxxxxxxxxxx3"], "aps": {"alert": "test message one!"}}');

$curl_scraped_page = curl_exec($ch);
