本项目还在实验中，目前并不稳定！

什么是GO？

或是出于优化 SEO，或是出于加强网站体验，很多博客都给文章中的外部链接加上了个二次跳转，本博客也不例外。

比如说我在这插入一个百度的超链接，你点击访问后先会被跳转到本博客的跳转页面，一段动画后才会真的转至百度的首页。

这里给出一个测试链接：https://kw-web-go.vercel.app/index.php?url=
只需要在后面添加一个链接就可以将任何链接“洗白”

分享一下php源码：

<?php
//自定义跳转地址
$cars = array(
    array("qcloud",'http://www.qcloud.com/redirect.php?redirect=1001&cps_key=8558139aea55e95d71f488081ba44577'),
    array("upyun",'https://www.upyun.com/league'),
    array("trustutn",'http://c.trustutn.org/s/aeink.com'),
    array("gfvps",'https://www.gfvps.cn/page.aspx?c=referral&u=9023'),
    array("360scan",'http://webscan.360.cn/index/checkwebsite/url/www.aeink.com')
 );

if(strlen($_SERVER['REQUEST_URI']) > 384 || strpos($_SERVER['REQUEST_URI'], "eval(") || strpos($_SERVER['REQUEST_URI'], "base64")) {
    @header("HTTP/1.1 414 Request-URI Too Long");
    @header("Status: 414 Request-URI Too Long");
    @header("Connection: Close");
    @exit;
}
//通过QUERY_STRING取得完整的传入数据，然后取得url=之后的所有值，兼容性更好
$t_url = htmlspecialchars(preg_replace('/^url=(.*)$/i','$1',$_SERVER["QUERY_STRING"]));

//此处可以自定义一些特别的外链，不需要可以删除以下5行
foreach($cars as $k=>$val){
    if($t_url==$val[0] ) {
        $t_url = $val[1];
        $t_vip = 1;
    }
}
 
//数据处理
if(!empty($t_url)) {
    //判断取值是否加密
    if ($t_url == base64_encode(base64_decode($t_url))) {
        $t_url = base64_decode($t_url);
    }
 //对取值进行网址校验和判断
preg_match('/^(http|https|thunder|qqdl|ed2k|Flashget|qbrowser):\/\//i',$t_url,$matches);
if($matches){
    $url=$t_url;
    $title='页面加载中,请稍候...';
} else {
    preg_match('/\./i',$t_url,$matche);
    if($matche){
        $url='http://'.$t_url;
        $title='页面加载中,请稍候...';
    } else {
        $url = 'http://'.$_SERVER['HTTP_HOST'];
        $title='参数错误，正在返回首页...';
    }
}
} else {
    $title = '参数缺失，正在返回首页...';
    $url = 'http://'.$_SERVER['HTTP_HOST'];
}
