站点底部显示的cdn回源节点炫酷代码

• ①

AMS HKG MFM是距离节点最近的机场缩写

所有节点查看：https://www.cloudflarestatus.com/

$.get("/cdn-cgi/trace",
        function(data) {

                                var know=false;
                for (var i = 0; i < every.length; i++) {
                        if (str == every[i][0]) {
                                                                var know=true;
                                $("#这里你的id元素").append("当前CDN节点:[" + every[i][1] + "]");
                        }
                }
                                if(know==false){$("#这里你的id元素").append("当前CDN节点:[" + str + "]");
                        }
                });

<div id="这里你的id元素"></div>

效果：当前CDN节点:[CloudFlare洛杉矶]
原理是/cdn-cgi/trace为cf的信息显示页面 通过ajax获取到信息后显示出来

})

补一个

ip.php

<?php
$IFcdn=empty($_SERVER['HTTP_CDN_LOOP']);
$JSON['status']=$IFcdn?"未启用CDN":"CDN启用";
$JSON['cdnip']=$_SERVER['REMOTE_ADDR'];
$JSON['realip']=$IFcdn ? $_SERVER['REMOTE_ADDR']:$_SERVER['HTTP_X_FORWARDED_FOR'];
echo json_encode($JSON);
?>

ip-query-qqwry.php

不要归属地直接删掉

PS 基本上都来自于笨牛CDN 在此声明

不启用CDN使用可能回输出些奇怪的东西 需要酌情修改JS..
