WordPress如何实现内容外链Base64加密外链转内链跳转
2021-11-0816:05:32评论2541字最近看到不少的小伙伴的博客外链接看不到明链，全部是加密过的。后来咨询了一下几个小伙伴，才知道这个Base64加密方式。下面给大家分享WordPress如何实现内容外链Base64加密外链转内链跳转。
第一步：修改Functions.php文件，将下面代码放入文件中。
//自动给文章的外部链接添加nofollow属性add_filter('the_content','web589_the_content_nofollow',999);function web589_the_content_nofollow($content){preg_match_all('/href="(http.*?)"/',$content,$matches);if($matches){foreach($matches[1] as $val){if( strpos($val,home_url())===false )$content=str_replace("href=\"$val\"", "rel=\"nofollow\" href=\"" . get_bloginfo('wpurl'). "/links?url=" .base64_encode($val). "\"",$content);}}return $content;}
第二步：在网站的根目录新建一个文件夹，名称：links，然后再links目录中创建一个index.php文件并将下面的代码放入（把www.huhexian.com改成自己的网址）：
<?php$url = $_GET['url'];$a = '';if( $a==$url ) {$b = "https://www.huhexian.com/";// echo 'true';} else {$b = $url;$b = base64_decode($b);}//Template Name:链接跳转（有过度）?><html><head><meta charset=utf-8 /><meta name="robots" content="nofollow"><meta http-equiv="refresh" content="0.1;url=<?php echo $b; ?>"><title>正在为您跳转……</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:41.5%;left:47%;margin:16px 0 0 35px;color:#BBB;letter-spacing:1px;font-weight:700;font-size:9px;font-family:Arial}.spinner{position:absolute;top:40%;left:45%;display:block;margin:0;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">加载中...</span><span class="spinner"></span></div></div></body></html>
这种外链方式可以将外部的链接加密成内链，这样一来可以隐藏地址URL，二来可以内链权重不至于流失，两全其美何乐而不为呢。
