为了假装在做SEO，避免权重分散，今天就给大家分享一个免插件实现WordPress外链go跳转，非常简单。
步骤一
在网站根目录新建一个go.php文件，记得将链接改为你的，代码如下：
<?php $t_url = preg_replace('/^url=(.*)$/i','$1',$_SERVER["QUERY_STRING"]); if(!empty($t_url)) { preg_match('/(http|https):\/\//',$t_url,$matches); if($matches){ $url=$t_url; $title='页面正在安全跳转中,请稍候'; } else { preg_match('/\./i',$t_url,$matche); if($matche){ $url='http://'.$t_url; $title='页面正在安全跳转中,请稍候'; } else { $url='//defcon.cn/'; $title='参数错误，正在返回首页'; } }} else { $title='参数缺失，正在返回首页'; $url='//www.tzwl420.club/';}?><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 $title;?></title><style>body {background:#000}.loading { -webkit-animation:fadein 2s; -moz-animation:fadein 2s; -o-animation:fadein 2s; animation:fadein 2s}@-moz-keyframes fadein {from {opacity:0}to {opacity:1}}@-webkit-keyframes fadein {from {opacity:0}to {opacity:1}}@-o-keyframes fadein {from {opacity:0}to {opacity:1}}@keyframes fadein {from {opacity:0}to {opacity:1}}.spinner-wrapper { position:absolute; top:0; left:0; z-index:300; height:100%; min-width:100%; min-height:100%; background:#3498db}.spinner-text { position:absolute; top:50%; left:50%; margin-left:-200px; margin-top: 2px; color:#fff; letter-spacing:1px; font-weight:700; font-size:36px; font-family:Arial}.spinner { position:absolute; top:50%; left:50%; display:block; margin-left:-270px; width:1px; height:1px; border:25px solid rgba(100,100,100,0.2); -webkit-border-radius:50px; -moz-border-radius:50px; border-radius:50px; border-left-color:transparent; border-right-color:transparent; -webkit-animation:spin 1.5s infinite; -moz-animation:spin 1.5s infinite; animation:spin 1.5s infinite}@-webkit-keyframes spin {0%,100% {-webkit-transform:rotate(0deg) scale(1)}50% {-webkit-transform:rotate(720deg) scale(0.6)}}@-moz-keyframes spin {0%,100% {-moz-transform:rotate(0deg) scale(1)}50% {-moz-transform:rotate(720deg) scale(0.6)}}@-o-keyframes spin {0%,100% {-o-transform:rotate(0deg) scale(1)}50% {-o-transform:rotate(720deg) scale(0.6)}}@keyframes spin {0%,100% {transform:rotate(0deg) scale(1)}50% {transform:rotate(720deg) scale(0.6)}}</style></head><body><div class="loading"> <div class="spinner-wrapper"> <span class="spinner-text">页面正在安全跳转中,请稍候</span> <span class="spinner"></span> </div></div></body></html>步骤二
将下面代码加到主题的functions.php文件中：
//给外部链接加上go跳转add_filter('the_content','the_content_nofollow',999);function the_content_nofollow($content){preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$content,$matches);if($matches){foreach($matches[2] as $val){if(strpos($val,'://')!==false && strpos($val,home_url())===false && !preg_match('/\.(jpg|jepg|png|ico|bmp|gif|tiff)/i',$val)){$content=str_replace("href=\"$val\"", "href=\"".home_url()."/go.php?url=$val\" ",$content);}}}return $content;}
