iOS : Send Multiple Apple Push Notification

Question

提前感谢那些愿意提供帮助的人

当我向单个设备发送推送通知时，我使用这种方法

<?php


  $deviceToken = $_POST['TOKEN'];
  $message = $_POST['MESSAGGIO'];

  $badge = 0;
  $sound = "default";

  $body = array();
  $body['aps'] = array("alert" => $message);


  if ($badge)
        $body['aps']['badge'] = $badge;
  if ($sound)
        $body['aps']['sound'] = $sound;

  $ctx = stream_context_create();
  stream_context_set_option($ctx, "ssl", "local_cert", "apns-dev.pem");

  $fp = stream_socket_client("ssl://gateway.push.apple.com:2195", $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);

  if (!$fp) {
       echo json_encode("errore");
       return;
  } 

  $payload = json_encode($body);

  $msg = chr(0) . pack("n",32) . pack("H*", str_replace(" ", "", $deviceToken)) . pack("n",strlen($payload)) . $payload;

  fwrite($fp, $msg);

  fclose($fp);


?>

当我必须向数据库中的所有设备发送通知时(当然使用设备 token )，我会想到这样做

<?php

  $deviceToken = $_POST['TOKEN'];
  $message = $_POST['MESSAGGIO'];

  $badge = 0;
  $sound = "default";

  $body = array();
  $body['aps'] = array("alert" => $message);


  if ($badge)
        $body['aps']['badge'] = $badge;
  if ($sound)
        $body['aps']['sound'] = $sound;

  $ctx = stream_context_create();
  stream_context_set_option($ctx, "ssl", "local_cert", "apns-dev.pem");

  $fp = stream_socket_client("ssl://gateway.push.apple.com:2195", $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);

  if (!$fp) {
   echo json_encode("errore");
   return;
  } 

  $payload = json_encode($body);

  //****

  $db = new PDO('sqlite:my_db.sqlite');

  $query = "SELECT device_token FROM user";
  $result = $db->query($query);

  foreach($result as $row){
    $msg = chr(0) . pack("n",32) . pack("H*", str_replace(" ", "", $row['device_token'])) . pack("n",strlen($payload)) . $payload;
    fwrite($fp, $msg);
  }

  //****

  fclose($fp);

?>

您认为这是正确的解决方案吗？

看起来是正确的。您使用同一个连接发送所有消息，这是发送多个通知时最重要的事情。

但是，您使用的是简单的二进制格式，它不支持错误响应，因此您没有错误处理。假设您的消息永远不会超过最大有效负载长度并且数据库中的所有设备 token 都有效，这将起作用。更好的方法是使用增强的二进制格式并读取(和处理)错误响应。
