让我们来看一下go跳转的效果：

步骤1

首先在站点根目录建立go目录，然后在go目录新建index.php文件，文件内容填写：

<?php
/**
* 自动跳转页面
* @copyright (c) Emlog All Rights Reserved
*/
//自定义跳转地址
$cars = array(
    array("qcloud",'https://www.qcloud.com/redirect.php?redirect=1001&cps_key=8558139aea55e95d71f488081ba44577'),
    array("upyun",'https://www.upyun.com/league'),
    array("trustutn",'https://c.trustutn.org/s/aeink.com'),
    array("gfvps",'https://www.gfvps.cn/page.aspx?c=referral&u=9023'),
    array("360scan",'https://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){
        $url='https://'.$t_url;
        $title='页面加载中,请稍候...';
    } else {
        $url = 'https://'.$_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...';
    $url = 'https://'.$_SERVER['HTTP_HOST'];
}
?>

        n = document.getElementById("js-sec-circle");
    document.getElementById("js-sec-text").innerHTML = t, setInterval(function() {
        //禁止其他网站调用此跳转
        //var MyHOST = new RegExp("<?php echo $_SERVER['HTTP_HOST']; ?>");
        //if (!MyHOST.test(document.referrer)) {
        // location.href="https://" + MyHOST;
        //}
        if (0 == t) location.href = "<?php echo $url;?>";
        else {
            t -= 1, document.getElementById("js-sec-text").innerHTML = t;
            var e = Math.round(t / 5 * 735);
            n.style.strokeDashoffset = e - 735
        }
    }, 970)
}
</script>
<script>alertSet("<?php echo $title;?>");</script>
</body>
</html>

步骤2

打开站点主题目录下的functions.php，插入如下内容：

//文章内外链添加go跳转
function the_content_nofollow($content){
    preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$content,$matches);
    if($matches){
        foreach($matches[2] as $val){
            if(strpos($val,'://')!==false && strpos($val,home_url())===false && strpos($val,'machunjie.com')===false && !preg_match('/\.(jpg|jepg|png|ico|bmp|gif|tiff)/i',$val)){
                $content=str_replace("href=\"$val\"", "href=\"".home_url()."/go/?url=$val\" ",$content);
            }
        }
    }
return $content;
}
add_filter('the_content','the_content_nofollow',999);


//评论者链接添加go跳转
function add_redirect_comment_link($text = ''){
    $text=str_replace('href="', 'href="'.get_option('home').'/go/?url=', $text);
    return $text;
}
add_filter('get_comment_author_link', 'add_redirect_comment_link', 5);
add_filter('comment_text', 'add_redirect_comment_link', 99);

然后我们在添加站外链接的时候，就会自动通过go跳转了，如果是站内链接，则会直接打开。
