第一种方法(虚拟主机反代)
将下面的代码保存为index.php

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; } /** * 根据文件后缀获取其mine类型 * @param string $extension * @return string */ function get_mimetype($extension) { $ct['htm'] = 'text/html'; $ct['html'] = 'text/html'; $ct['txt'] = 'text/plain'; $ct['asc'] = 'text/plain'; $ct['bmp'] = 'image/bmp'; $ct['gif'] = 'image/gif'; $ct['jpeg'] = 'image/jpeg'; $ct['jpg'] = 'image/jpeg'; $ct['jpe'] = 'image/jpeg'; $ct['png'] = 'image/png'; $ct['ico'] = 'image/vnd.microsoft.icon'; $ct['mpeg'] = 'video/mpeg'; $ct['mpg'] = 'video/mpeg'; $ct['mpe'] = 'video/mpeg'; $ct['qt'] = 'video/quicktime'; $ct['mov'] = 'video/quicktime'; $ct['avi'] = 'video/x-msvideo'; $ct['wmv'] = 'video/x-ms-wmv'; $ct['mp2'] = 'audio/mpeg'; $ct['mp3'] = 'audio/mpeg'; $ct['rm'] = 'audio/x-pn-realaudio'; $ct['ram'] = 'audio/x-pn-realaudio'; $ct['rpm'] = 'audio/x-pn-realaudio-plugin'; $ct['ra'] = 'audio/x-realaudio'; $ct['wav'] = 'audio/x-wav'; $ct['css'] = 'text/css'; $ct['zip'] = 'application/zip'; $ct['pdf'] = 'application/pdf'; $ct['doc'] = 'application/msword'; $ct['bin'] = 'application/octet-stream'; $ct['exe'] = 'application/octet-stream'; $ct['class'] = 'application/octet-stream'; $ct['dll'] = 'application/octet-stream'; $ct['xls'] = 'application/vnd.ms-excel'; $ct['ppt'] = 'application/vnd.ms-powerpoint'; $ct['wbxml'] = 'application/vnd.wap.wbxml'; $ct['wmlc'] = 'application/vnd.wap.wmlc'; $ct['wmlsc'] = 'application/vnd.wap.wmlscriptc'; $ct['dvi'] = 'application/x-dvi'; $ct['spl'] = 'application/x-futuresplash'; $ct['gtar'] = 'application/x-gtar'; $ct['gzip'] = 'application/x-gzip'; $ct['js'] = 'application/javascript'; $ct['swf'] = 'application/x-shockwave-flash'; $ct['tar'] = 'application/x-tar'; $ct['7z'] = 'application/x7zcompressed'; $ct['rar'] = 'application/x-rar-compressed'; $ct['xhtml'] = 'application/xhtml+xml'; $ct['au'] = 'audio/basic'; $ct['snd'] = 'audio/basic'; $ct['midi'] = 'audio/midi'; $ct['mid'] = 'audio/midi'; $ct['m3u'] = 'audio/x-mpegurl'; $ct['tiff'] = 'image/tiff'; $ct['tif'] = 'image/tiff'; $ct['rtf'] = 'text/rtf'; $ct['wml'] = 'text/vnd.wap.wml'; $ct['wmls'] = 'text/vnd.wap.wmlscript'; $ct['xsl'] = 'text/xml'; $ct['xml'] = 'text/xml'; return isset($ct[strtolower($extension)]) ? $ct[strtolower($extension)] : 'text/html'; } 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) 例子:jsd-proxy-sand.vercel.app直接替换cdn.jsdelivr.net即可 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 { "version": 2, "routes": [ {"src": "/(.*)","dest": "https://cdn.jsdelivr.net/$1"} ] } 第五步 vercel -A vercel.json --prod 可以连接现有项目 也可以新建个项目
