尝试通过php文件执行Apple Push Notification时出错

Question

我正在使用php服务器在IOS中进行推送通知，并且我生成了应用程序的证书和密钥，而且我还确保从ssl：//portway.sandbox.push.apple.com：2196和2195的解锁端口中进行访问，但是在在尝试连接ssl的过程中，每次遇到此错误时，我也从所有密钥文件的权限中确定

Warning: stream_socket_client(): SSL: crypto enabling timeout in /Users/samahahmaed/Desktop/CER/newspush.php on line 24

Warning: stream_socket_client(): Failed to enable crypto in /Users/samahahmaed/Desktop/CER/newspush.php on line 24

Warning: stream_socket_client(): unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Unknown error) in /Users/samahahmaed/Desktop/CER/newspush.php on line 24
Failed to connect: 0

当我尝试此命令时

openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert PushCertificate.pem -key PushKey.pem -CApath /etc/ssl/certs/Entrust_Root_Certification_Authority.pem

我得到这个错误

CONNECTED(00000003)
write:errno=54

php文件：

  <?php

  // Put your device token here (without spaces):
  $deviceToken = 'mydevicetokenhere';

 // Put your private key's passphrase here:
 $passphrase = '1234';

 $message = $argv[1];
 $url = $argv[2];

 if (!$message || !$url)
exit('Example Usage: $php newspush.php \'Breaking News!\'   \'https://raywenderlich.com\'' . "\n");



$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert',  'apple_push_notification_production.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

// Open a connection to the APNS server
  $fp = stream_socket_client(
  'ssl://gateway.sandbox.push.apple.com:2195', $err,
  $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

  if (!$fp)
  exit("Failed to connect: $err $errstr" . PHP_EOL);

  echo 'Connected to APNS' . PHP_EOL;

  // Create the payload body
   $body['aps'] = array(
   'alert' => $message,
   'sound' => 'default',
   'link_url' => $url,
  );

  // Encode the payload as JSON
   $payload = json_encode($body);

 // Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

 // Send it to the server
 $result = fwrite($fp, $msg, strlen($msg));

 if (!$result)
  echo 'Message not delivered' . PHP_EOL;
 else
  echo 'Message successfully delivered' . PHP_EOL;

 // Close the connection to the server
  fclose($fp);

我搜索了很多有关此问题的内容，并尝试了所有可能的解决方案，但没有任何结果，我现在能做什么？

在将-debug添加到openssl命令之后，这些行最奇怪的是：

Answer 1

stream_context_set_option($ctx, 'ssl', 'local_cert',  'apple_push_notification_production.pem');

这条线看起来像您在使用生产证书来连接到沙箱APNS。 尝试使用开发证书。 您可以从Apple开发人员仪表板获得相同的信息。
