使用PHP服务器端在IONIC 2上推送通知

<?php
function sendPushNotification($deviceToken, $message) {
    $url = 'https://fcm.googleapis.com/fcm/send';
    $serverKey = 'YOUR_SERVER_KEY';

    $headers = array(
        'Authorization: key=' . $serverKey,
        'Content-Type: application/json'
    );

    $data = array(
        'to' => $deviceToken,
        'notification' => array(
            'title' => 'Notification Title',
            'body' => $message,
            'sound' => 'default',
            'click_action' => 'FCM_PLUGIN_ACTIVITY'
        )
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    $result = curl_exec($ch);
    curl_close($ch);

    return $result;
}

// 调用函数发送推送通知
$deviceToken = 'DEVICE_TOKEN';
$message = 'Hello, World!';
$response = sendPushNotification($deviceToken, $message);
echo $response;
?>
