有没有办法通过推送套件接收通知

Question

我想在 iOS 中应用程序被终止时收到静默推送通知。所以我在我的应用程序中实现了推送工具包框架。有什么方法可以通过推送套件发送通知吗？作为 FCM 控制台或推送尝试。

Answer 1

FCM 不支持静默推送通知。

Firebase Cloud Messaging 是否支持 VOIP 推送套件服务？

您可以尝试使用以下php文件和终端命令。

Php 文件

<?php
// Put your device token here (without spaces):

$deviceToken = '1234567890123456789';
//

// Put your private key's passphrase here:
$passphrase = 'ProjectName';
// Put your alert message here:
$message = 'My first silent push notification!';

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'PemFileName.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,
'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(
'content-available'=> 1,
'alert' => $message,
'sound' => 'default',
'badge' => 0,
);

// 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);

使用以下命令创建 pem 文件并在上面的代码中使用它

$ openssl x509 -in aps_development.cer -inform der -out PushCert.pem
// Convert .p12 to .pem. Enter your pass pharse which is the same pwd that you have given while creating the .p12 certificate. PEM pass phrase also same as .p12 cert.  
$ openssl pkcs12 -nocerts -out PushKey1.pem -in pushkey.p12
Enter Import Password:
MAC verified OK
Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
// To remove passpharse for the key to access globally. This only solved my stream_socket_client() & certificate capath warnings.
$ openssl rsa -in PushKey1.pem -out PushKey1_Rmv.pem
Enter pass phrase for PushChatKey1.pem:
writing RSA key
// To join the two .pem file into one file:
$ cat PushCert.pem PushKey1_Rmv.pem > ApnsDev.pem
