第一种方法(虚拟主机反代)
将下面的代码保存为index.php
<?php
$file = $_SERVER['REQUEST_URI'];
$self_path = pathinfo($_SERVER['PHP_SELF'], PATHINFO_DIRNAME);
$query = '';
if($_SERVER['QUERY_STRING'])
{
$file = explode('?', $file)[0];
$query = '?' . $_SERVER['QUERY_STRING'];
}
$file_info = pathinfo($file);
$path = $file_info['dirname'];
if($path=='/') exit('/* ??? */');
$mimetype = get_mimetype($file_info['extension']);
$cdn_file = $file;
if(strlen($self_path)>1){
$cdn_file = substr($file, strlen($self_path));
}
$local_path = substr(pathinfo( $cdn_file, PATHINFO_DIRNAME), 1);
if($local_path && !is_dir($local_path)){
@mkdir($local_path, 755, true);
}
$url = 'https://cdn.jsdelivr.net' . $cdn_file . $query;
$content = curl($url);
if($content){
header('content-type:'. $mimetype .';charset=utf-8');
echo '/* ' . $url .'*/';
file_put_contents(substr($cdn_file, 1), $content);
exit($content);
}else{
header('location: ' .$url );
}
function curl($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT_MS, 3000);
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 3000);
if (strpos($url, 'https') !== false) {
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
}
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.190 Safari/537.36');
$result = curl_exec($ch);
curl_close($ch);
return $result;
}

用法介绍
如果放在根目录，直接把cdn.jsdelivr.net替换成你的域名就好了
如果放在某个子目录下，比如cdn目录下，把cdn.jsdelivr.net替换成你的域名/cdn（如https://> example.com/cdn）即可
第二种办法(vercel反代)
需要的：vercel账号(绑定了github) 、node.js
第一步
npm install -g cnpm --registry=https://registry.npmmirror.com
第二步
cnpm i -g vercel
第三步
vercel login
记得选择github登录 你会看到一个是否同意nodejs打开网页的提示框 选是
###第四步
创建并进入一个新的文件夹
在文件夹内创建vercel.json内容
