使用 Api 使用推送通知

我正在尝试使用 Api 使用推送通知，但没有收到任何错误消息，也没有收到任何响应.

I am trying to use push notification using Api and I am not getting any error message neither I am getting any response.

我已经检查了 使用 PHP 脚本的 Apple 推送通知服务

并相应地对我的代码进行了更改，但仍然无法正常工作.

and applied changes in my code accordingly but still not working.

我不知道如何获取我必须在其中使用的 serverId

I am not able to get how to get serverId that I have to use in

$device = 'fbb5a9c71066794d57fee33b4005a89f1bb8941a68660fd6e91f466be1299ab6'; // My iphone deviceToken
$payload['aps'] = array(
    'alert' => 'This is the alert text',
    'badge' => 1,
    'sound' => 'default'
);

$payload['server'] = array(
    'serverId' => 1,
    'name' => 'keyss.in'
);

$payload = json_encode($payload);

$apnsCert = 'apple_push_notification_production.pem';

$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);

$apns = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $error, $errorString, 2, STREAM_CLIENT_CONNECT, $streamContext);

$apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $device)) . chr(0) . chr(strlen($payload)) . $payload;
fwrite($apns, $apnsMessage);

//socket_close($apns); seems to be wrong here ...
fclose($apns);
    

获取错误:
