1、网站根目录新建 `go` 文件夹放入 `index.php` 文件，内容如下：

<code class="language-php">
<?php
// https://www.scczz.com
$t_url = preg_replace('/^url=(.*)$/i','$1',$_SERVER["QUERY_STRING"]);  
if(!empty($t_url)) {  
    preg_match('/(http|https):\/\//',$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='https://www.scczz.com';  
            $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://www.scczz.com';  
}  
?>  
<html>  
<head>  
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">  
<meta http-equiv="refresh" content="1;url='<?php echo $url;?>';">  
<title><?php echo $title;?></title>  
<style>  
body{background:#000}.loading{-webkit-animation:fadein 2s;-moz-animation:fadein 2s;-o-animation:fadein 2s;animation:fadein 2s}@-moz-keyframes fadein{from{opacity:0}to{opacity:1}}@-webkit-keyframes fadein{from{opacity:0}to{opacity:1}}@-o-keyframes fadein{from{opacity:0}to{opacity:1}}@keyframes fadein{from{opacity:0}to{opacity:1}}.spinner-wrapper{position:absolute;top:0;left:0;z-index:300;height:100%;min-width:100%;min-height:100%;background:rgba(255,255,255,0.93)}.spinner-text{position:absolute;top:50%;left:50%;margin-left:-90px;margin-top: 2px;color:#BBB;letter-spacing:1px;font-weight:700;font-size:36px;font-family:Arial}.spinner{position:absolute;top:50%;left:50%;display:block;margin-left:-160px;width:1px;height:1px;border:25px solid rgba(100,100,100,0.2);-webkit-border-radius:50px;-moz-border-radius:50px;border-radius:50px;border-left-color:transparent;border-right-color:transparent;-webkit-animation:spin 1.5s infinite;-moz-animation:spin 1.5s infinite;animation:spin 1.5s infinite}@-webkit-keyframes spin{0%,100%{-webkit-transform:rotate(0deg) scale(1)}50%{-webkit-transform:rotate(720deg) scale(0.6)}}@-moz-keyframes spin{0%,100%{-moz-transform:rotate(0deg) scale(1)}50%{-moz-transform:rotate(720deg) scale(0.6)}}@-o-keyframes spin{0%,100%{-o-transform:rotate(0deg) scale(1)}50%{-o-transform:rotate(720deg) scale(0.6)}}@keyframes spin{0%,100%{transform:rotate(0deg) scale(1)}50%{transform:rotate(720deg) scale(0.6)}}  
</style>  
</head>  
<body>  
<div class="loading">  
  <div class="spinner-wrapper">  
    <span class="spinner-text">页面加载中,请稍候...</span>  
    <span class="spinner"></span>  
  </div>  
</div>  
</body>  
</html>

2、外链自动识别，在主题的 `functions.php` 文件中加入以下代码：

<code class="language-php">
/*文章外部链接加上跳转*/
add_filter('the_content','the_content_nofollow',999);  
function the_content_nofollow($content)  
{  
    preg_match_all('/<a(.*?)href="(.*?)" rel="nofollow noopener" (.*?)>/',$content,$matches);  
    if($matches){  
        foreach($matches[2] as $val){  
            if(strpos($val,'://')!==false && strpos($val,home_url())===false && !preg_match('/\.(jpg|jepg|png|ico|bmp|gif|tiff)/i',$val)){  
                $content=str_replace("href=\"$val\"", "href=\"".home_url()."/go/?url=$val\" ",$content);  
            }  
        }  
    }  
    return $content;  
}
 
 
/*评论处的链接新窗口打开并添加跳转*/
function get_comment_author_link_new($return, $author, $comment_ID = 0) {
$comment = get_comment( $comment_ID );
$url = get_comment_author_url( $comment );
$author = get_comment_author( $comment );
 
if ( empty( $url ) || 'http://' == $url )
$return = $author;
else
 
$return = "<a href='$url' target='_blank' rel="external nofollow noopener noreferrer" class='url'>$author</a>";
$return=str_replace("href='$url'", "href=\"".home_url()."/go/?url=$url\" ",$return);//添加go跳转
 
return $return;
}
add_filter('get_comment_author_link', 'get_comment_author_link_new', 10, 3);
