代码实现给网站添加外链跳转emlog

首先是PHP版本的跳转代码

<?php 
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
$t_url = preg_replace('/^url=(.*)$/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
if($t_url=="senqi" ) {
   $t_url="https://www.blogs.hk";
} elseif($t_url=="baidu") {
   $t_url="https://www.baidu.com/";
}

//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'];
}
?>

<script>
function link_jump()
{
    //禁止其他网站使用我们的跳转页面
    var MyHOST = new RegExp("<?php echo $_SERVER['HTTP_HOST']; ?>");
    if (!MyHOST.test(document.referrer)) {
         location.href="http://" + MyHOST;
    }
    location.href="<?php echo $url;?>";
}
//延时1S跳转，可自行修改延时时间
setTimeout(link_jump, 1000);
//延时50S关闭跳转页面，用于文件下载后不会关闭跳转页的问题
setTimeout(function(){window.opener=null;window.close();}, 50000);
</script>
<title><?php echo $title;?></title>

</html>

将以上代码保存为go.php上传到网站根目录即可。

然后是JS版本的，这算是这次的彩蛋吧！偶然的灵感，让我想到了其实可以用 js+html 纯静态来搞定这个跳转功能。测了又测，终于新鲜出炉！和PHP基本一致的功能，可以放心使用！

选择JS 版本将以上代码保存为 go.html 上传到网站根目录即可。

Ps：2个版本的功能是一致的，优缺点区别：PHP版本是动态的，会略微产生服务器的性能负载，而JS版本则需要浏览器支持JS才可以功能。不过目前来看，绝大部分浏览器都是支持的！
