APNS-通知推送ios:对等PHP重置连接

问题描述

我的Push Notifications工作正常.但是有时候，从无处开始会出现错误:

I have had Push Notifications working fine. But some of the times, from nowhere it starts giving error:

stream_socket_client():SSL:对等方重置连接

stream_socket_client(): SSL: Connection reset by peer

我知道这是许多问题的重复，例如: notifications-push-ios-connection-reset-by-peer 但是它们都不能解决我的问题.

I know it is a duplicate of many questions like:notifications-push-ios-connection-reset-by-peerBut none of them solves my problem.

我正在使用PHP stream_socket_client生成套接字连接

I am using PHP stream_socket_client to generate the socket connection

正在使用的代码是:

 <?php
ini_set('display_errors','On');
error_reporting(E_ALL);
$deviceToken= 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$passphrase = ' ';
$message = 'my first notification';
////////////////////////////////////////////////////////////////////////////////
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// Open a connection to the APNS server
$fp = stream_socket_client(
    'ssl://gateway.sandbox.push.apple.com:2195', $err,
    $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp)
    exit("Failed to connect: $err $errstr" . PHP_EOL);
echo 'Connected to APNS' . PHP_EOL;
// Create the payload body
$body['aps'] = array(
    'alert' => $message,
    'sound' => 'default'
    );

// Encode the payload as JSON
$payload = json_encode($body);
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
if (!$result)
    echo 'Message not delivered' . PHP_EOL;
else
    echo 'Message successfully delivered' . PHP_EOL;
// Close the connection
}

推荐答案

我无法真正指出主要原因.

I can't really put my finger on main reason for it.

但是请确保您没有做错以下任何事情:

But please make sure, you are not doing any of the below things wrong:

• 不要并行建立许多连接.传递推送通知"后，请重用同一连接或关闭该连接.实际上，服务器有最大并行连接数限制，一旦达到阈值，这可能会给您带来麻烦.另外，苹果公司建议除非您知道连接将处于空闲状态，否则将其保持打开状态.

• Don't make many connections in parallel. Either reuse the same connection or close the connection after delivering Push Notifications. Actually, servers have a limit for maximum number of parallel connections, which might leave you in trouble, once you reach threshold. Also Apple suggests leave a connection open unless you know it will be idle.

• 请勿将开发者配置文件令牌发送到LIVE APNS.将分发和开发应用程序令牌分开.如果您尝试将沙盒令牌发送到LIVE APNS，反之亦然，则可能会导致错误.
• Don't send out developer profile tokens to LIVE APNS. Keep distribution and development app tokens separate. It could result in error, if you try to send sandbox tokens to LIVE APNS or vice versa.
