php如何做cdn加速器

<?php
// 假设使用Cloudflare的CDN服务
$cdnApiUrl = 'https://api.cloudflare.com/client/v4/zones/{zone_id}/files';
$apiKey = 'your_cloudflare_api_key';
$zoneId = 'your_cloudflare_zone_id';

// 要上传的文件路径
$filePath = '/path/to/your/file.jpg';

// 构建请求头
$headers = [
    'Authorization: Bearer ' . $apiKey,
    'Content-Type: application/json',
];

// 构建请求体
$data = [
    'file' => fopen($filePath, 'r'),
    'name' => basename($filePath),
];

// 发送POST请求到CDN API
$response = curl_init();
curl_setopt_array($response, [
    CURLOPT_URL => $cdnApiUrl,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => json_encode($data),
    CURLOPT_HTTPHEADER => $headers,
]);
$result = curl_exec($response);
curl_close($response);

// 解析响应并获取文件URL
$responseData = json_decode($result, true);
if (isset($responseData['result']['url'])) {
    $cdnUrl = $responseData['result']['url'];
    echo "File uploaded to CDN: " . $cdnUrl;
} else {
    echo "Failed to upload file to CDN.";
}
?>
