Push Notification in PHP using PEM file

问题:

I've been working through Ray Wenderlich's tutorials on push notifications using a PHP Script.

Reference: http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1

http://www.raywenderlich.com/32963/apple-push-notification-services-in-ios-6-tutorial-part-2

I have done a ton of research but I have ran into an issue on part 2 where you run the push.php file using the ck.pem file.

/Applications/XAMPP/bin/php push.php development

My only difference is that I'm using XAMPP and not MAMP.

I have confirmed that all the extensions are installed.

I am able to test out my certificate in the terminal by doing this:

openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert PushChatCert.pem -key PushChatKey.pem

It asks me to enter my passphrase and I do. Everything works successfully in the terminal.

However, when I run the push.php file, I get these errors:

PHP Warning: stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed PHP Warning: stream_socket_client(): Failed to enable crypto in

PHP Warning: stream_socket_client(): unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Unknown error) in on line 140

Line 140 in the php file is:

$this->fp = stream_socket_client('ssl://' . $this->server, $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

I found these:

Push notification in PHP

I have literally retried everything. I know my passphrase is correct. I've re-created my certificates, pem files, and keys. Nothing works. Same error every time I do this.

I'm beyond confused.

Does anyone have any suggestions or know what's going on?

Thank you!

UPDATE 1:

I have also tried setting the full path to the ck.pem file that does not fix the error either.

Okay, I finally figured this out! After 2 days of working with this.

So, for anyone else who runs into this issue:

Download the entrust_2048_ca.cer certificate from: https://www.entrust.com/get-support/ssl-certificate-support/root-certificate-downloads/

Scroll down and get the Entrust.net Certificate Authority (2048)

Then, in the push.php file, after you set the context for the passphrase, add this line: stream_context_set_option($ctx, 'ssl', 'cafile', 'entrust_2048_ca.cer');

Updated to macOS Sierra 10.12.4

The problem is in new PHP Version in macOS Sierra. They changed the way it works with certificates.

I would suggest a small changes in the accepted answer to make things explicit.

You have to setup path to entrust_2048_ca.cer and other parameters during creation of the stream context like

$streamContext = stream_context_create([
        'ssl' => [
            'verify_peer'      => true,
            'verify_peer_name' => true,
            'cafile'           => '/path/to/bundle/entrust_2048_ca.cer',
        ]
    ]);

Update to macOS sierra 10.12.5

please add

stream_context_set_option($ctx, 'ssl', 'verify_peer', false);

The problem is in new PHP Version in macOS Sierra

回答4:

add

stream_context_set_option($ctx, 'ssl', 'verify_peer', false);

which defeats the server validation. Credits @One In a Million Apps in a comment above.
