测试推送通知

在你为服务器端做好准备之前，测试推送通知的工作原理始终是一个好习惯，只是为了确保所有内容都能正确设置。使用以下 PHP 脚本向你自己发送推送通知非常容易。

1. 将脚本保存为文件（例如 send_push.php）与证书（开发或生产）相同的文件夹中
2. 编辑它以从证书中输入你的设备令牌，密码
3. 选择正确的路径来打开连接，dev_path 或 prod_path（这是在脚本中“打开与 APNS 服务器的连接”的地方）
4. cd 到终端中的文件夹并运行命令’php send_push'
5. 在你的设备上接收通知

// Put your final pem cert name here. it is supposed to be in the same folder as this script
$cert_name = 'final_cert.pem';
// Put your private key's passphrase here:
$passphrase = '1234';
