Push notifications from linux for iOS apps via SSL with PHP - php

Question

Do you know how to sent push notifications to IOS app from php?
It's best answer for somebody http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1
But it doesn't work:
$production = 0;
$passphrase = "kaka";
$deviceToken = "bf38e156 29adac02 6b9b2ec6 35aa4381 df90df65 8238a13c d7f55261 798c3923";
$message = "Hello people! What are you doing?";
$deviceToken = str_replace(" ", "", $deviceToken);
// Create a Stream
$ctx = stream_context_create();
// Define the certificate to use
stream_context_set_option($ctx, "ssl", "local_cert", "CerAndKey.pem");
// Passphrase to the certificate
//stream_context_set_option($ctx, "ssl", "passphrase", $passphrase);
stream_context_set_option($ctx, "ssl", "verify_peer", true);
// load certificate
stream_context_set_option($ctx, "ssl", "cafile", "CerAndKey.pem");
if ($production) {
$gateway = "gateway.push.apple.com:2195";
} else {
$gateway = "gateway.sandbox.push.apple.com:2195";
}
$fp = stream_socket_client($gateway,
$err,
$errstr,
60,
STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT,
$ctx);
if (!$fp)
exit("Failed to connect amarnew: $err $errstr" . PHP_EOL);
echo "Connected to APNS" . PHP_EOL;
// Create the payload body
$body["aps"] = array(
"badge" => +1,
"alert" => $message,
"sound" => "default"
);
$payload = json_encode($body);
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
// Ensure that blocking is disabled
//stream_set_blocking($fp, 0);
// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
print_r($result);
if (!$result)
echo 'Message not delivered' . PHP_EOL;
else
echo 'Message successfully delivered amar '.$message. PHP_EOL;
// Close the connection to the server
fclose($fp);

Answer 1

Many people don't know how is right. PHP can diferent work in linux-systems. If you want I tell you howto easy use it.
Step by step:
1. Generate ssl keys:
#!/bin/bash
## From
# http://stackoverflow.com/questions/24344325/how-to-use-linux-openssl-to-generate-csr-for-ios
openssl genrsa -out ios-dev.key 2048
openssl req -new -key ios-dev.key -out ios-dev.csr
# You must upload to Apple -> Identifiers -> App IDs -> <project> -> edit -> Push Notifications -> Create Certificate ->
# then download -> aps_development.cer
# and put file here
2. Prepare key whith certificate for server script.
#!/bin/bash
## from
# https://gist.github.com/stevenhaddox/1501893
# http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1
openssl x509 -in aps_development.cer -inform der -out CertAndKeyDevCert.pem
##cp CertAndKeyDevCert.pem /etc/ssl/certs/
openssl rsa -in ios-dev.key -out CertAndKeyDevKey.pem -outform PEM
cat CertAndKeyDevCert.pem CertAndKeyDevKey.pem > CertAndKey.pem
3. Connect to Apple server for test
#!/bin/bash
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert CertAndKey.pem -key CertAndKey.pem -CAfile CertAndKey.pem
Result in console:

Right responce:
1. verify return:1
2. Verify return code: 0 (ok)
Your certivicate and key are OK!
Next step is php-script:
$production = 0;
$keyFile = "CertAndKey.pem";
$deviceToken = "bf38e156 29adac02 6b9b2ec6 35aa4381 df90df65 8238a13c d7f55261 798c3923";
$message = "Ещё одно ...";
$deviceToken = str_replace(" ", "", $deviceToken);
if ($production) {
$gateway = 'gateway.push.apple.com:2195';
} else {
$gateway = 'gateway.sandbox.push.apple.com:2195';
}
// Create the payload body
$body['aps'] = array(
'badge' => +1,
'alert' => $message,
'sound' => 'default',
);
$payload = json_encode($body);
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
$filepath = "/tmp/sentPush.dat";
file_put_contents($filepath,$msg);
$command = "cat ".$filepath." | openssl s_client -connect ".$gateway." -cert ".$keyFile." -key ".$keyFile." -CAfile ".$keyFile." 2>&1";
exec($command, $tmp);
$last = end($tmp);
unlink($filepath);
if ($last=="DONE"){
$result = "Message successfully!";
}else{
$result = "ERROR:Message not send" . PHP_EOL;
}
This solution will work somewhere, because I use only openssl.

Answer 2

+1 is not allowed for badge
Store the badge number where you store the device tokens and update it with every push notification.

Answer 3

There are some points that should be kept in mind:
This problem might be occur due to $production = 0;. It should be $production = true;
Try to use the full path for .pem file .=> stream_context_set_option($ctx, "ssl", "local_cert", "CerAndKey.pem");
use __FILE__ to get full path like: stream_context_set_option($ctx, "ssl", "local_cert", "(full-path-to-file)/CerAndKey.pem");
Double check the device token used to send notifications.
And in last try chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $item[0])) . chr(0) . chr(strlen($payload)) . $payload;
instead of
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
May be it helps to you or someone else. Should try once.

Answer 4

Here are a few tips that should can help you figure out:
Go to entrust.net/downloads/root_request.cfm and download entrust_2048_ca.cer
Add following code:
stream_context_set_option($ctx, 'ssl', 'cafile', 'entrust_2048_ca.cer');
Make sure if path is right: 'CerAndKey.pem'? not'../XXfolder/CerAndKey.pem' ?
Cancel the line of verify_peer setting;
Instead, you should set passphrase - the password that you entered when exporting p12 from KeyChain.
Switch and try both the sandbox and live ssl links.
Switch dev and production pem and try both.
