php - Send push notification to ios app : Google cloud -

-

i have hosted php code on google cloud.

i want send push notifications ios app. have enabled port 2195 , 2196.

while sending push notification got following error :

warning: stream_socket_client(): ssl: connection reset peer

warning: stream_socket_client(): failed enable crypto

warning: stream_socket_client(): unable connect ssl://gateway.push.apple.com:2195 (unknown error)

i not familiar google cloud. should make working?

here code:

$ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', pem_file_path . 'apns-dev.pem');  $fp = stream_socket_client("ssl://gateway.push.apple.com:2195", $err, $errstr, 60, stream_client_connect, $ctx);  if (!$fp) {     $data['msgs'] = "failed connect $err $errstr \n"; } else {     $payload = json_encode($body);     $msg = chr(0) . pack("n", 32) . pack("h*", str_replace(" ", "", $devicetoken)) . pack("n", strlen($payload)) . $payload;      $result = fwrite($fp, $msg);      if (!$result) {         $data['msgs'] = 'message not delivered'; //. php_eol;     } else {         $data['msgs'] = 'success'; //. php_eol;     }      fclose($fp); } return $data;

the main problem when trying send data apns (apple push notification service) servers ssl certificates.

apns uses technology in order serve more secure connection users.

as said @ apns documentation: "each certificate limited single app , limited 1 of 2 development environments, each own assigned hostname". can use 2 environments

  • development (testing environment): ssl://gateway.sandbox.push.apple.com:2195

  • production (once app launched): ssl://gateway.push.apple.com:2195

if want test if can connect apns server, try following command:

$ telnet gateway.sandbox.push.apple.com 2195 trying 17.172.232.226... connected gateway.sandbox.push-apple.com.akadns.net. escape character '^]'.

if error make sure firewall allows outgoing connections on port 2195.

then can test if ssl certificate , private key working , can set secure connection:

$ openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert yourdevcert.pem -key yourprivatekey.pem enter pass phrase yourprivatekey.pem: ******

if works means certificates correctly set (you should see whole bunch of output, openssl letting know going on under hood).

once knowing of information, see have 1 mistake in code , should check else:

  • check if have connection apns server.
  • check $payload variable json string.
  • check have correct $devicetoken.
  • check using right certificate right environtment. in case, setting apns-dev.pem certificate , sending production environment (i interpret production certificate apns-prod.pem check it).
  • check php file can find certificate.
  • one of your problems, haven't set password private key. should add following line once have added certificate:

stream_context_set_option($ctx, "ssl", "passphrase", "your_private_key");

if have troubles or doubts, followed this tutorial send first apns push notifications.
