PHP Apple增强推送通知读取错误响应

在PHP中，如何在发送增强的推送通知时使用fread（）来检查是否有错误响应？

我已经阅读了苹果的文档，通过谷歌几个模糊的post，和一些问题/答案在这里，但这仍然是非常混乱。

下面是我看到的： http : //developer.apple.com/library/mac/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/IPhoneOSClientImp/IPhoneOSClientImp.html 从苹果增强推送通知读取错误与 iPhone iPhone推送通知 – 错误响应问题

我将在下面回答我自己的问题，基于以下事实：（1）我发现这是一个令人困惑的话题，（2）我必须将信息连同大量的反复试验结合起来， （3）这个博客文章说，这是鼓励： http : //blog.stackoverflow.com/2011/07/its-ok-to-ask-and-answer-your-own-questions/

当您发送推送通知时，有几个问题：

• 如果出现问题，苹果会断开你的连接，但你不知道。 当你使用基本的通知，没有办法知道他们是否全部发送。 解决scheme：这是使用增强型通知然后检查错误响应的关键。 请注意，我们将在数据库查询中使用“ORDER BY ID”，然后使用该ID作为我们在通知中发送的标识符。 这样，如果出现问题，我们知道数据库中的哪一行导致了问题（因此我们知道苹果何时断开连接并停止发送通知）。 然后，我们可以继续将推送通知发送到造成问题的行之后的所有行，而不必重新发送到我们已经发送到的行。

• 如果一切正常，苹果公司不会发回任何回应，所以这可能会导致脚本暂停并等待，而fread（）正在等待未到的数据。 解决方法：需要将stream_set_blocking设置为0，以便fread总是立即返回。 请注意，这会导致fread在接收到错误响应之前返回的另一个小问题，但请在代码中查看解决方法，只需暂停1/2秒后，您的所有发送完成，然后再次检查fread 。

• 您可以发送多个推送通知，比发送错误响应要快得多。 解决方法：再次，这是上面提到的相同的解决方法…暂停1/2秒后，所有的发送完成，然后再次检查fread一次。

这里是我使用PHP的解决scheme，它解决了我遇到的所有问题。 它非常基本，但完成工作。 我已经testing了一次发送几个通知，同时发送了12万个。

<?php /* * Read Error Response when sending Apple Enhanced Push Notification * * This assumes your iOS devices have the proper code to add their device tokens * to the db and also the proper code to receive push notifications when sent. * */ //database $host = "localhost"; $user = "my_db_username"; $pass = "my_db_password"; $dbname = "my_db_name"; $con = mysql_connect($host, $user, $pass); if (!$con) { die('Could not connect to database: ' . mysql_error()); } else { mysql_select_db($dbname, $con); } // IMPORTANT: make sure you ORDER BY id column $result = mysql_query("SELECT id,token FROM `device_tokens` ORDER BY id"); //Setup notification message $body = array(); $body['aps'] = array('alert' => 'My push notification message!'); $body['aps']['notifurl'] = 'http://www.myexampledomain.com'; $body['aps']['badge'] = 1; //Setup stream (connect to Apple Push Server) $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'passphrase', 'password_for_apns.pem_file'); stream_context_set_option($ctx, 'ssl', 'local_cert', 'apns.pem'); $fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx); stream_set_blocking ($fp, 0); //This allows fread() to return right away when there are no errors. But it can also miss errors during last seconds of sending, as there is a delay before error is returned. Workaround is to pause briefly AFTER sending last notification, and then do one more fread() to see if anything else is there. if (!$fp) { //ERROR echo "Failed to connect (stream_socket_client): $err $errstrn"; } else { $apple_expiry = time() + (90 * 24 * 60 * 60); //Keep push alive (waiting for delivery) for 90 days //Loop thru tokens from database while($row = mysql_fetch_array($result)) { $apple_identifier = $row["id"]; $deviceToken = $row["token"]; $payload = json_encode($body); //Enhanced Notification $msg = pack("C", 1) . pack("N", $apple_identifier) . pack("N", $apple_expiry) . pack("n", 32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n", strlen($payload)) . $payload; //SEND PUSH fwrite($fp, $msg); //We can check if an error has been returned while we are sending, but we also need to check once more after we are done sending in case there was a delay with error response. checkAppleErrorResponse($fp); } //Workaround to check if there were any errors during the last seconds of sending. usleep(500000); //Pause for half a second.

Should return nothing if OK. $apple_error_response = fread($fp, 6); //NOTE: Make sure you set stream_set_blocking($fp, 0) or else fread will pause your script and wait forever when there is no response to be sent. if ($apple_error_response) { //unpack the error response (first byte 'command" should always be 8) $error_response = unpack('Ccommand/Cstatus_code/Nidentifier', $apple_error_response); if ($error_response['status_code'] == '0') { $error_response['status_code'] = '0-No errors encountered'; } else if ($error_response['status_code'] == '1') { $error_response['status_code'] = '1-Processing error'; } else if ($error_response['status_code'] == '2') { $error_response['status_code'] = '2-Missing device token'; } else if ($error_response['status_code'] == '3') { $error_response['status_code'] = '3-Missing topic'; } else if ($error_response['status_code'] == '4') { $error_response['status_code'] = '4-Missing payload'; } else if ($error_response['status_code'] == '5') { $error_response['status_code'] = '5-Invalid token size'; } else if ($error_response['status_code'] == '6') { $error_response['status_code'] = '6-Invalid topic size'; } else if ($error_response['status_code'] == '7') { $error_response['status_code'] = '7-Invalid payload size'; } else if ($error_response['status_code'] == '8') { $error_response['status_code'] = '8-Invalid token'; } else if ($error_response['status_code'] == '255') { $error_response['status_code'] = '255-None (unknown)'; } else { $error_response['status_code'] = $error_response['status_code'] .

我不确定你的代码的内容，但你应该尝试ApnsPHP它是经过充分testing的作品完美无瑕 ，它能够为您处理所有可能的exception和错误。

已经testing了3个例子中的2个，没有实现和错误pipe理的问题。

谢谢
