APNS:无效令牌导致所有后续推送通知失败 [英] APNS: Invalid token causes all subsequent push notifications to fail

问题描述

我正在使用狡猾的PHP推送通知库，但是无论我是否发送全部，都会发生相同的情况我的推送通知完全是手动的，没有库(如下面的脚本中所示).如果我的SQL数据库中存在无效的令牌，并且我尝试向该令牌发送推送，则我与 ssl://gateway.push.apple.com:2195 和所有后续令牌断开了连接不接受推送.如何发现无效令牌并将其从数据库中删除，或者遇到无效令牌后如何继续发送推送?我下面的一个php脚本(虽然不是上面的库)却遭受相同的错误:

 ///将您的设备令牌放在此处(不带空格):$ iosTokens =数组(xxxx，xxxx，xxxx);//将私钥的密码放在这里:$ passphrase ='';$ message =消息";$ url ="URL";如果(！$ message ||！$ url)exit('示例用法:$ php newspush.php \'Breaking News！\'\'https://raywenderlich.com \''."\ n");///////////////////////////////////////////////////////////////////////////////////$ ctx = stream_context_create();stream_context_set_option($ ctx，'ssl'，'local_cert'，'../../../PEMs/siouxFallsStampede.pem');stream_context_set_option($ ctx，'ssl'，'passphrase'，$ passphrase);//打开与APNS服务器的连接$ fp = stream_socket_client('ssl://gateway.push.apple.com:2195'，$ err，$ errstr，60，STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT，$ ctx)；如果(！$ fp)exit(无法连接:$ err $ errstr".PHP_EOL);回显已连接到APNS".PHP_EOL;//创建有效载荷主体$ body ['aps'] = array('alert'=>$消息，'声音'=>'默认'，'link_url'=>$ url，);//将有效负载编码为JSON$ payload = json_encode($ body);foreach($ iosTokens as $ devicetoken){//构建二进制通知$ msg = chr(0).pack('n'，32).pack('H *'，$ devicetoken).pack('n'，strlen($ payload)).$ payload;//将其发送到服务器$ result = fwrite($ fp，$ msg，strlen($ msg));var_dump($ result);如果(！$ result)回显消息未传递".PHP_EOL;别的回显消息已成功传递".PHP_EOL;}//关闭与服务器的连接fclose($ fp); 

解决方案

此问题已解决Sly PHP Push Notification library, but the same thing happens whether I send all my push notifications completely manually, without the library (like in the script below). If there is an invalid token in my SQL database and I attempt to send a push to that token, I am disconnected from ssl://gateway.push.apple.com:2195 and all the subsequent tokens do not receive the push. How can I either spot invalid tokens and remove them from my database, or continue to send out pushes after I come across an invalid token? A php script I have below (though not the Library above) suffers from the same bug:

// Put your device token here (without spaces):
$iosTokens = array(xxxx, xxxx, xxxx);

// Put your private key's passphrase here:
$passphrase = '';

$message = "Message";
$url = "URL";

if (!$message || !$url)
    exit('Example Usage: $php newspush.php \'Breaking News!\' \'https://raywenderlich.com\'' . "\n");

////////////////////////////////////////////////////////////////////////////////

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', '../../../PEMs/siouxFallsStampede.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

// Open a connection to the APNS server
$fp = stream_socket_client(
  'ssl://gateway.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',
  'link_url' => $url,
  );

// Encode the payload as JSON
$payload = json_encode($body);

foreach($iosTokens as $devicetoken) {

    // 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));

    var_dump($result);
    if (!$result)
      echo 'Message not delivered' . PHP_EOL;
    else
      echo 'Message successfully delivered' . PHP_EOL;

}

// Close the connection to the server
fclose($fp);

解决方案

This was solved here. What I did was ordered the tokens by ID, when a token was invalid, I removed it from my SQL database and continued sending a push to just those tokens with an ID higher than the invalid one (so ordering by ID is crucial).
