通过PHP (curl)发送Apple推送通知

告诉我如何在CURL php上通过推送的方式发送消息?这个承诺不起作用:

 $ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://gateway.push.apple.com:2195');
 curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_HEADER, 1);
 curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));
 curl_setopt($ch, CURLOPT_POST, 1);
 curl_setopt($ch, CURLOPT_SSLCERT,'1.pem');
 curl_setopt($ch, CURLOPT_SSLCERTPASSWD, "12345");
 curl_setopt($ch, CURLOPT_POSTFIELDS, '{"device_tokens": ["........................................."], "aps": {"alert": "test message one!"}}');
 $curl_scraped_page = curl_exec($ch);
 echo $curl_scraped_page;
