iPhone SDK 推送通知随机失败 [英] iPhone SDK Push notification randomly fails

问题描述

我有一个包含以下内容的 PHP 文件，它可以完美地用于开发证书，但是当我切换到生产证书时，PHP 错误并给出以下消息，但它只有大约 50% 的时间这样做.其他 50% 有效.有人知道为什么会发生这种情况吗?

I have a PHP file with the following content that works perfectly on development ceritficates, but when I switch to a production certificate the PHP errors and gives the below message, but it only does this about 50% of the time. The other 50% it works. Anyone know why this might be happening?

<?php
// masked for security reason 
$deviceToken = 'xxxxxx'; // jq

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', dirname(__FILE__)."/prod.pem");

$number = 5;

$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
if (!$fp) {
  print "Failed to connect $err $errstr\n";
}
else {
  print "Connection OK\n";
  $msg = $_GET['msg'];
    $payload['aps'] = array('alert' => $msg, 'badge' => 1, 'sound' => 'default');
    $payload = json_encode($payload);

  $msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload;
  print "sending message :" . $payload . "\n";
  fwrite($fp, $msg);
  fclose($fp);
}
?>

推荐答案

我遇到了同样的问题.您必须与 Apple 的 Push Notification Server 建立持久的套接字连接.我已经为一个名为 pyapns 的 python 守护进程编写了一个教程(http://github.com/samuraisam/pyapns) 对我来说效果很好:

I had the same issue. You have to make a persistent socket connection with Apple's Push Notification Server. I've written up a tutorial for a python daemon called pyapns (http://github.com/samuraisam/pyapns) which worked very well for me:

假设您正在运行 Debian 并且具有安装所需软件包(例如 python-twisted、libcurl4-openssl-dev 等)的 root 访问权限，则此方法有效.

This works assuming you are running Debian and have root access to install the required packages such as python-twisted, libcurl4-openssl-dev etc.
