参考张戈大大的代码,写了两个跳转文件,一个是采用PHP跳转的版本,一个是采用js跳转的版本,代码如下:
PHP版本的跳转文件:
<?php 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 $t_url = preg_replace('/^url=(.*)$/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 if($t_url=="liubiji" ) { $t_url="//i.cuixt.com"; } elseif($t_url=="bAIdu") { $t_url="https://www.baidu.com/"; } //数据处理 if(!empty($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">对方网速可能太慢,留笔记为你拼命加载中,别急哦...</span> <span class="spinner"></span> </div> </div> </body> </html>
你可以把上述代码保存为go.php文件(UTF-8无BOM),放到空间的根目录。
JS版本的代码如下:

你可以把上述代码保存为go.html文件(UTF-8无BOM),放到空间的根目录。
PS:2个版本的功能是一致的,优缺点区别:PHP版本是动态的,会略微产生服务器的性能负载,而JS版本则需要浏览 器支持JS才可以功能。不过目前来看,绝大部分浏览器都是支持的!(张戈原话)
通过上面的文件,我们可以通过go.php?url=网址的方式打开个外链(比如http://wpspy.org/tools/go.php?url=www.baidu.com,我的go.php放在tools文件夹),或者通过go.php?url=网址加密串来打开外链(比如http://wpspy.org/tools/go.php?url=aHR0cDovL3d3dy5iYWlkdS5jb20=),但是我们还不能使goto/网址加密串来访问,因为这是需要做伪静态的。
实现伪静态很简单,只要在Nginx中加入如下规则即可:
PHP版本:
# 外链跳转伪静态 php版本
rewrite ^/go/(.*)$ /go.php?url=$1 last; #注意go.php的实际路径,默认为网站根目录
JS版本:
# 外链跳转伪静态 js 版本
rewrite ^/go/(.*)$ /go.html?url=$1 last; #注意go.html 的实际路径,默认为网站根目录
通过以上设置并重启Nginx后,就可以直接使用go/网址加密串来访问了,比如http://wpspy.org/go/aHR0cDovL3d3dy5iYWlkdS5jb20=
以上只是跳转功能的实现,我们还需要把wordpress里面的所有外链进行替换,因为我是beginning的主题,张戈大大使用的是begin的主题,代码并不适配,所以我修改了下,用于替换文章中的外链为go/网址加密串形式:
//文章外链跳转伪静态版 add_filter('the_content','link_jump',999); function link_jump($container){ preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$container,$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)){ $container=str_replace("href="$val"", "href="".home_url()."/go/".base64_encode($val)."" rel="nofollow"",$container); } } } return $container; }
上面的代码仅能替换beginning主题文章中的外链,如果你想替换文章正文外链转换+评论内容外链+访客的头像链接的话,可以直接使用下面的版本(代码来自inlojv有改动):
function convert_to_internal_links($content){ preg_match_all('/shref=('|")(http[^'"#]*?)('|")([s]?)/',$content,$matches); if($matches){ foreach($matches[2] as $val){ if(strpos($val,home_url())===false){ $rep = $matches[1][0].$val.$matches[3][0]; $new = '"'.home_url().'/go/'.base64_encode($val).'" target="_blank"'; $content = str_replace("$rep","$new",$content); } } } return $content; } add_filter('the_content','convert_to_internal_links',99); // 文章正文外链转换 add_filter('comment_text','convert_to_internal_links',99); // 评论内容的链接转换 add_filter('get_comment_author_link','convert_to_internal_links',99); // 访客的链接转换 function inlo_redirect() { $baseurl = 'go'; $request = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; $hop_base = trailingslashit(trailingslashit(home_url()).$baseurl); // 删除末尾的 斜杠/ 符号 if (substr($request,0,strlen($hop_base)) != $hop_base) return false; $hop_key = str_ireplace($hop_base, '', $request); if(substr($hop_key, -1) == '/')$hop_key = substr($hop_key, 0, -1); if (!empty($hop_key)) { $url = base64_decode($hop_key); wp_redirect( $url, 302 ); exit; } } add_action('template_redirect','inlo_redirect');
