编辑 - 使用增强二进制格式
事实证明我没有使用增强二进制格式,因此我修改了我的代码。

尽管我使用了这段新的代码,但由于出现错误,我仍然不能发送超过300多条信息:
Warning: fwrite() [function.fwrite]: SSL operation failed with code 1. OpenSSL Error messages: error:1409F07F:SSL routines:SSL3_WRITE_PENDING:bad write retry in PATH_TO_SCRIPT.php on line NUMBER
当发送少量推送消息时,此代码可以正常工作。
具有简单二进制格式的旧问题很久以前,我集成了推送通知功能,并且对于发送给少于500人的消息,它可以正常工作。现在我正在尝试向1000多人发送推送通知,但是我遇到了错误。
Warning: fwrite() [function.fwrite]: SSL: Broken pipe in PATH_TO.PHP on line x
我已经阅读了苹果文档,知道无效的令牌会导致套接字断开连接。一些在线解决方案建议检测断开连接并重新连接,就像这个:
Your server needs to detect disconnections and reconnect if necessary. Nothing is
"instant" when networking is involved; there's always some latency and code needs to take
that into account. Also, consider using the enhanced binary interface so you can check the
return response and know why the connection was dropped. The connection can also be
dropped as a result of TCP keep-alive, which is outside of Apple's control.
我还运行着一项反馈服务,用于检测无效令牌(想要推送通知但已删除应用程序的用户),并且工作正常。该PHP脚本会回显已删除的ID,并且我可以确认那些令牌已从我们的MySQL数据库中删除。
我该如何检测到断开连接或破损的管道,并对此做出反应,以便我的推送通知能够覆盖超过1000人?
目前,我正在使用这个简单的push.php脚本。
<?php
$message = $_POST['message'];
$passphrase = $_POST['pass'];
//Connect to database stuff
if ($db_found) {
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', 'x.pem');
stream_context_set_option($streamContext, 'ssl', 'passphrase', $passphrase);
$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $error, $errorString, 15, STREAM_CLIENT_CONNECT, $streamContext);
if (!$fp)
exit("Failed to connect: $err $errstr" . PHP_EOL);
echo 'Connected to APNS for Push Notification' . PHP_EOL;
$deviceToken[] = //GET ALL TOKENS FROM DATABASE AND STORE IN ARRAY
for($i = 0; $i<count($deviceToken); $i++) {
// 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*', $deviceToken[$i]) . pack('n', strlen($payload)) . $payload;
// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
$bodyError .= 'result: '.$result.', devicetoken: '.$deviceToken[$i].'';
if (!$result) {
$errCounter = $errCounter + 1;
echo 'Message not delivered' . PHP_EOL;
}
else
echo 'Message successfully delivered' . PHP_EOL;
}
echo $bodyError;
// Close the connection to the server
fclose($fp);
//CODE TO SAVE MESSAGE TO DATABSE HERE
if (!mysql_query($SQL,$db_handle)) {
die('Error: ' . mysql_error());
}
}
else {
print "Database niet gevonden ";
mysql_close($db_handle);
}
?>
同时,当SLL断开连接错误发生时,fwrite返回0个写入字节。
我必须提到,我不是PHP或Web开发者,而是应用程序开发者,因此我的PHP技能并不那么好。
checkAppleErrorResponse($fp);
函数是否有任何回显?我看到您在循环内调用它,但您没有检查其返回值。如果该函数打印错误,则应处理它并再次进行fwrite,然后再转到下一个项目。 - LombaX
