如何在php中使用FCM实现web推送通知

<?php
function sendPushNotification($title, $message, $token) {
    $url = 'https://fcm.googleapis.com/fcm/send';
    $serverKey = 'YOUR_SERVER_KEY'; // 替换为你的服务器密钥
    $headers = array(
        'Authorization: key=' . $serverKey,
        'Content-Type: application/json'
    );

    $data = array(
        'to' => $token,
        'notification' => array(
            'title' => $title,
            'body' => $message,
            'icon' => 'your-icon-url' // 替换为你的图标URL
        )
    );

    $payload = json_encode($data);

    $ch = curl_init();
    curl_setopt($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, $payload);

    $result = curl_exec($ch);
    curl_close($ch);

    return $result;
}

// 使用示例
$title = '新消息';
$message = '你有一条新的通知';
$token = 'DEVICE_TOKEN'; // 替换为你的设备令牌
$response = sendPushNotification($title, $message, $token);
echo $response;
?>
