废话不多说，直接上教程：
1、找到主题的function文件，一般为主题根目录的functions.php，在最下方（如果有
?php>
，在
?php>
上方）添加如下代码：
//文章外链跳转伪静态版function link_jump($content){ preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$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) && !preg_match('/(ed2k|thunder|Flashget|flashget|qqdl):\/\//i',$val)){ $content=str_replace("href=\"$val\"", "href=\"".home_url()."/goto/".base64_encode($val).".html\" rel=\"nofollow\"",$content); } } } return $content;}add_filter('the_content','link_jump',999);
2、在网站根目录建立goto.php文件，文件粘贴如下代码：
<?phpif(strlen($_SERVER['REQUEST_URI']) > 255 ||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"]);//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'];}?><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><meta name="robots" content="noindex, nofollow" /><noscript><meta http-equiv="refresh" content="1;url='<?php echo $url;?>';"></noscript><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 $title;?></title><style type="text/css">body{background:#555}.loading{-webkit-animation:fadein 2s;-moz-animation:fadein 2s;-o-animation:fadein 2s;animation:fadein 2s}@-moz-keyframes fadein{from{opacity:0}to{opacity:1}}@-webkit-keyframes fadein{from{opacity:0}to{opacity:1}}@-o-keyframes fadein{from{opacity:0}to{opacity:1}}@keyframes fadein{from{opacity:0}to{opacity:1}}.spinner-wrapper{position:absolute;top:0;left:0;z-index:300;height:100%;min-width:100%;min-height:100%;background:rgba(255,255,255,0.93)}.spinner-text{position:absolute;top:45%;left:50%;margin-left:-100px;margin-top:2px;color:#000;letter-spacing:1px;font-size:20px;font-family:Arial}.spinner{position:absolute;top:45%;left:50%;display:block;margin-left:-160px;width:1px;height:1px;border:20px solid rgba(255,0,0,1);-webkit-border-radius:50px;-moz-border-radius:50px;border-radius:50px;border-left-color:transparent;border-right-color:transparent;-webkit-animation:spin 1.5s infinite;-moz-animation:spin 1.5s infinite;animation:spin 1.5s infinite}@-webkit-keyframes spin{0%,100%{-webkit-transform:rotate(0deg) scale(1)}50%{-webkit-transform:rotate(720deg) scale(0.6)}}@-moz-keyframes spin{0%,100%{-moz-transform:rotate(0deg) scale(1)}50%{-moz-transform:rotate(720deg) scale(0.6)}}@-o-keyframes spin{0%,100%{-o-transform:rotate(0deg) scale(1)}50%{-o-transform:rotate(720deg) scale(0.6)}}@keyframes spin{0%,100%{transform:rotate(0deg) scale(1)}50%{transform:rotate(720deg) scale(0.6)}}</style></head><body><div class="loading"><div class="spinner-wrapper"><span class="spinner-text">页面加载中，请稍候...</span><span class="spinner"></span></div></div></body></html>
3、在伪静态规则中添加一条跳转伪静态，以nginx规则为例，代码如下：
rewrite /goto/(.*)$ /goto.php?url=$1;
至此，大功告成！
