某些用户不再收到或发送 IOS 推送通知

Question

我遇到了以下问题。

我有一个运行两年的 IOS 应用程序，推送通知没有问题。

我基本上所做的是将所有注册 ID 存储在数据库中，并通过 php 脚本向它们发送通知：

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

$title = "My App";

$nachricht = $message['teams']['heim']." - ". $message['teams']['aus'];
// Create the payload body
$body['aps'] = array(
    'alert' => $title. " \n " . $nachricht,
    'sound' => 'default',
    'message' => $nachricht
    );
$body['id'] = $message['spiel'];
$body['message'] = $nachricht;
$body['title'] = $title;

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

for ($i = 0; $i < count($registation_ids); $i++) {
    // Build the binary notification
    $msg = chr(0) . pack('n', 32) . pack('H*', $registation_ids[$i]) . pack('n', strlen($payload)) . $payload;

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

}
fclose($fp);

这个脚本我从来没有遇到过任何问题，但现在一些几周前收到通知的用户不再收到通知了。首先我认为我的证书和提供配置文件有问题，但是具有相同 IOS 版本和 App 版本的其他用户仍然收到通知。 我还检查了用户不再收到消息的通知设置，它们是正确的。

什么会导致这个问题？ 目前我不知道错误发生在哪里。
