PHP：向iOS发送推送通知

PHP：向iOS发送推送通知

8

我正在使用PHP将推送通知发送给iOS设备。目前，我的代码已经运行良好，以下是我所使用的代码：

$passphrase = '';
$badge = 1;
$path = base_path('path/to/certificate.pem');
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', $path);
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
$fp = stream_socket_client(
    'ssl://gateway.sandbox.push.apple.com:2195', $err,
    $errstr, 60, STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT, $ctx
);

if (!$fp) {
    self::SavePush($device_token, $message, $device_id, $device_type, $user_id, "pending", "normal", null);
}

//echo 'Connected to APNS' . PHP_EOL;
$body['aps'] = array(
    'alert' => $message,
    'badge' => $badge,
    'sound' => 'default'
);
$payload = json_encode($body);
$msg = chr(0) . pack('n', 32) . pack('H*', $device_token) . pack('n', strlen($payload)) . $payload;
$result = fwrite($fp, $msg, strlen($msg));

//print_r($result);exit;

if (!$result) {
    self::SavePush($device_token, $message, $device_id, $device_type, $user_id, "pending", "normal", null, $result);
} else {
    self::SavePush($device_token, $message, $device_id, $device_type, $user_id, "sent", "normal", null, $result);
}

fclose($fp);

现在我面临的问题是，我无法确定通知是否失败，因为$result在每种情况下都包含一个整数，无论成功还是失败。我传递了一个随机数字作为令牌，它返回像115或65这样的整数，并且每次都会更改。所以!$result不能工作。我如何知道通知是否失败？

当你使用fwrite将某些东西发送到APNS之后，你需要使用fread（或stream_get_contents ;)）读取响应。最好的方法是使用非阻塞连接（stream_set_blocking($fp, 0);）并在简单的时间限制循环中等待响应:

$read = '';
$to = time() + 2;  // max 2 seconds wait...
while (!feof($fp)) // ...or end of connection
{
    $r = stream_get_contents($fp);
    if (strlen($r) > 0)
        $read .= $r;
    if (time() >= $to)
        break;
    usleep(100000);
}

接下来，在$read中，您将会得到“something”或者是“nothing”。如果得到的是“something”（确切地说是6个字节），那么就意味着出现了错误（$error = unpack('Ccommand/Cstatus/Nident', $read);）。如果得到的是“nothing”或者长度短于/长于6个字节，那么就意味着消息发送成功。

我希望能够澄清一个重要的观点：正如苹果所说，由于推送是以这种方式工作的，所以“没有交付保证”。

因此，你可以像其他人建议的那样测试网络错误，但你无法保证接收到了通知。为了实现这一点，唯一（长...）的方法是在iOS设备上触发一个URL请求，当它接收到推送时。这个URL请求将更新你的数据库。

调用fwrite()将返回成功发送的字节数，如果发送时出现错误，则返回FALSE。您的$result会因为所发送信息的大小而改变。因此，如果$result===FALSE，则表示发送失败，通知未能成功。如果$result!==FALSE，则表示通知已成功发送。这仅验证了消息是否通过网络发送。它不验证消息结构或令牌的有效性等任何内容。

现在，如果您想确定推送通知本身是否有效，以及苹果是否接受并正在处理它，那么您可能需要使用CURL和HTTP/2来完成。通过快速谷歌搜索，我找到了这个网站，其中展示了如何进行演示。我还没有测试过该网站http://coding.tabasoft.it/ios/sending-push-notification-with-http2-and-php/，因此无法告诉您演示是否正确。这只是一个快速搜索，但可能会让您走上正确的道路。
