通过虚拟主机反代JSD

自从去年底jsdelivr的备案被吊销后，其在我国大陆地区的速度相较于此前慢了非常多，最重要的是有一些地区都不能访问(间断阻断)

推荐商家

速度很快的。(我博客就在用)
，免费主机试试可以。我没用过

基础

随意新建一个php文件，比如dl.php
让后黏贴下方代码，访问域名/dl.php?https://cdn.jsdelivr.net/

<?php
if(isset($_GET['url'])==false){die("请将参数填写完整，在当前路径后加上?url=反代的链接");}
$token=(string)rand(100,99999);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $_GET['url']);
curl_setopt($ch, CURLOPT_HEADER,false);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION ,1); 
if(isset($_SERVER['HTTP_REFERER'])==true){curl_setopt($ch, CURLOPT_REFERER, $_SERVER['HTTP_REFERER']);}
$data_down = curl_exec($ch);
if($data_down === FALSE){die("代理时发生错误");}
curl_close($ch);
file_put_contents($token, $data_down);
header('Content-Type: '.mime_content_type($token));
unlink($token);
echo $data_down;
?>1

高级

如果你认为上边的链接太长了，可以使用这个方法

<?php
//代理的域名及使用的协议最后不用加/
$target_host="https://cdn.jsdelivr.net";
//处理代理的主机得到协议和主机名称
$protocal_host=parse_url($target_host);
//解决中文乱码
#header("Content-Type:text/html;charset=gb2312"); 
//获取浏览器的的Agent
$Agent = $_SERVER['HTTP_USER_AGENT'];
//以.分割域名字符串
$rootdomain=explode(".",$_SERVER["SERVER_NAME"]);
//获取数组的长度
$lenth=count($rootdomain);
//获取顶级域名
$top=".".$rootdomain[$lenth-1];
//获取主域名
$root=".".$rootdomain[$lenth-2];

//解析url参数
