Question

我使用以下代码获取推送通知。但我收到类似 Warning: stream_socket_client() [function.stream-socket-client]: 无法连接到 ssl://gateway.sandbox.push.apple.com:2195 的错误（无法找到套接字传输“ssl” - 您在配置 PHP 时是否忘记启用它？）在第 21 行的 D:\xampp\htdocs\push_test\push_test.php 连接失败：5 无法找到套接字传输“ssl” - 您在配置 PHP 时是否忘记启用它？ 我不知道该怎么办。请帮忙..

// Put your device token here (without spaces):
$deviceToken = 'xxxxxxxxxxxxxxxxxxxxxx';

// Put your private key's passphrase here:
$passphrase = 'xxxxxxxxx';

// Put your alert message here:
$message = 'My first push notification!';

////////////////////////////////////////////////////////////////////////////////

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert',      'server_certificates_bundle_sandbox.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);

这表明您尚未在服务器上启用 OpenSSL 支持，请检查并告诉我。
