php - iOS 推送通知发送错误

Question

我是一名 iOS 应用程序开发人员，对 php 了解不多。我正在关注 raywenderlich push notification tutorial为推送通知生成 SSL 证书和私钥。

我按照这些步骤操作了 3-4 次，但它不起作用。我之前遵循了相同的步骤并且成功了。

我认为问题出在我测试使用 SSL 证书连接到 APNS 服务器时得到的响应中。我得到低于响应。

在响应开始时，它给出错误 verify error:num=20:unable to get local issuer certificate。在响应的后面部分，它还显示 No client certificate CA names sent。我不知道这些事情，但我怀疑问题出在这些错误上。

编辑:使用教程中提供的示例 php 脚本发送通知时出现错误。

Warning: stream_socket_client(): Unable to set private key file `/Users/akashpatel/Desktop/SimplePush/ck.pem' in /Users/akashpatel/Desktop/SimplePush/simplepush.php on line 25

Warning: stream_socket_client(): failed to create an SSL handle in /Users/akashpatel/Desktop/SimplePush/simplepush.php on line 25

编辑:使用这个app (由 segev 在他的回答中建议)我测试了证书/私钥是否有任何问题。我可以成功收到通知。所以我想问题不在于证书/私钥。

我正在使用的 PHP 脚本:

<?php

$deviceToken = 'r34f34f5g45g5y56u76hj676elfjn4urno43f958gh945g8g7';

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

// Put your alert message here:
$message = 'Received push 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 to the server
fclose($fp);

编辑: 我的脚本在生产服务器中使用时有效。但我会保留这个问题，因为它在本地服务器上不起作用。建议可能会帮助那些不在生产服务器上工作的其他人。

推送通知有太多问题，您需要一一解决。

暂时忘掉 php 代码。去here并下载最新版本。

这是一个很棒的小应用程序，可以为您完成所有服务器端的工作，并会向您的设备发送推送通知。如果可行，您可以继续执行 php 代码，但我怀疑您的问题出在应用程序证书\ key 上。
