php - 如何在 iPhone 中一次性向多个设备发送推送通知？

Question

我想向所有注册了应用程序的设备发送相同的消息，但是如何在不建立多个连接的情况下发送它们...

我当前的 PHP 代码:

ctx = stream_context_create();  
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');  
$fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);  
if (!$fp)
{
  print "Failed to connect $err $errstr\n";
  return;
}
$msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload;
fwrite($fp, $msg);

最重要的是，你不能。您需要向每个 token 发送消息。

Its not working like a email where you can have multiple recipients.

连接打开后，您可以发送一堆消息，这也是首选方式(基于 Apples SDK)。

来自 SDK:

You should also retain connections with APNs across multiple notifications. APNs may consider connections that are rapidly and repeatedly established and torn down as a denial-of-service attack. Upon error, APNs closes the connection on which the error occurred.
