带有 PHP 脚本的 Apple 推送通知

我能够连接到apns并将值插入数据库，只需检查我收到"消息已传递"消息，但它没有显示任何通知....谁能告诉我我错在哪里...

$deviceToken = '**********************';

$payload['aps'] = array('alert' => 'This is the alert text', 'badge'
=> 1, 'sound' => 'default'); $payload = json_encode($payload);
$passphrase = '***';

$apnsHost = 'gateway.sandbox.push.apple.com'; $apnsPort = 2195; $apnsCert = 'ck.pem';
$streamContext = stream_context_create(); stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert); stream_context_set_option($streamContext, 'ssl', 'passphrase',$passphrase );
$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 2, STREAM_CLIENT_CONNECT, $streamContext);
if (!$apns)
    {
     $check = $errorString;      $query = "INSERT INTO tbl_checkData(friend_nickname) VALUES('$check') ";    $result=mysql_query($query);           } else{ 
     $check = "connected";   $query = "INSERT INTO tbl_checkData(friend_nickname) VALUES('$check') ";    $result=mysql_query($query);    }
$apnsMessage = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload;
//chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $deviceToken)) . chr(0) . chr(strlen($payload)) . $payload;
$result=fwrite($apns, $apnsMessage);
if (!$result)
    {
     $check = 'Message not delivered' ;      $query = "INSERT INTO tbl_checkData(friend_nickname) VALUES('$check') ";    $result=mysql_query($query);       
            } else {     $check = 'Message delivered' ;      $query = "INSERT INTO tbl_checkData(friend_nickname) VALUES('$check') ";    $result=mysql_query($query);    
     }
enter code here
fclose($apns);
