p12生成pem证书

1. 通过终端命令将这些文件转换为PEM格式：openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12
openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-cert.p12
2.最后，你需要将键和许可文件合成为apns-dev.pem文件，此文件在连接到APNS时需要使用：

cat apns-dev-cert.pem apns-dev-key.pem >apns-dev.pem

<?php
//php需要开启ssl(OpenSSL)支持
$apnsCert = "ck.pem";//连接到APNS时的证书许可文件，证书需格外按要求创建
$pass = "123456";//证书口令
$serverUrl = "ssl://gateway.sandbox.push.apple.com:2195";//push服务器，这里是开发测试服务器
$deviceToken = "a8fcd4aa8943b223d4ebcd54fe168a8b99b3f24c63dbc0612db25a8c0a588675";//ios设备id，中间不能有空格，每个ios设备一个id
$message = $_GET ['message'] or $message = "hello!";
$badge = ( int ) $_GET ['badge'] or $badge = 2;
$sound = $_GET ['sound'] or $sound = "default";
$body = array('aps' => array('alert' => $message , 'badge' => $badge , 'sound' => $sound));
$streamContext = stream_context_create();
stream_context_set_option ( $streamContext, 'ssl', 'local_cert', $apnsCert );
stream_context_set_option ( $streamContext, 'ssl', 'passphrase', $pass );
$apns = stream_socket_client ( $serverUrl, $error, $errorString, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $streamContext);//连接服务器
if ($apns) {
echo "Connection OK <br/>";
} else {
echo "Failed to connect $errorString";
return;
}
$payload = json_encode ( $body );
$msg = chr(0) . pack('n', 32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack('n', strlen($payload)) . $payload;
$result = fwrite ( $apns, $msg);//发送消息
fclose ( $apns );
if ($result)
echo "Sending message successfully: " . $payload;
else
echo 'Message not delivered';
?>
