作为站长,都需要了解WordPress网站外链转内链的优化代码,今天就特意为大家分享一下WordPress如何实现外链加密及伪静态跳转?外链转内链跳转地址为 Base64 加密地址的详细步骤:

1、将以下跳转代码保存为 index.php,然后在网站根目录新建一个 go 文件夹,并把 index.php 上传到 go 文件夹中:

<?php

if(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\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”]);

//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==\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”yigujin\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” ) {

$t_url=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”https://www.yigujin.cn\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”;

} elseif($t_url==\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”nana\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”) {

$t_url=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”https://www.yigujin.cn/nana\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”;

}

//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\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’];

其中第行代码中自定义的一些特别外链,这个功能特别好,因为我们每个站点都或多或少有一些特殊的外链,如果也变成 Base64 加密地址就不好看了,所以此处我们可以多添加几个比较有个性化的外链跳转地址。

2、将以下代码添加到我们的 Nginx 服务器相应配置文件中的 location / { 前面,保存配置文件后平滑重启 Nginx 即可:

rewrite ^/goto/(.*)$ /go/?url=$1 last;

3、替换文章原外链跳转地址格式(/go/?url=外链)变更为新的外链格式(/goto/ base64 加密串),我们只需要将以下代码代替主题文件的 functions.php 文件中原先给外部链接加上跳转的代码即可:

//文章外链跳转伪静态版

add_filter(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’the_content\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’link_jump\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,999);

function link_jump($content){

preg_match_all(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’/<a(.*?)href=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”https://www.wpzt.net/(.*?)\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”(.*?)>/\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,$content,$matches);

if($matches){

foreach($matches[2] as $val){

if(strpos($val,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’://\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’)!==false && strpos($val,home_url())===false && !preg_match(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’/\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\.(jpg|jepg|jpg|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($val).\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”,$content);

}

}

}

return $content;

}

4、对于评论外链,是不需要改变成 base64 加密串的,保持原汁原味会比较好,所以本站就没有做评论外链跳转的相关操作,所以这步更变评论外链的步骤直接忽略。

5、将下载原外链跳转地址格式(/go/?url=外链)变更为新的外链格式(/goto/ base64 加密串),我们首先将以下代码添加到主题文件 functions.php 文件最后一个?>(记得修改代码中的 boke112.com 为自己的域名)。

// 下载外链跳转

function links_nofollow($url) {

if(strpos($url,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’://\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’)!==false && strpos($url,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’boke112.com\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’)===false && !preg_match(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’/(ed2k|thunder|Flashget|flashget|qqdl):\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\/\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\//i\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,$url)) {

$url = str_replace($url, home_url().\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”/goto/\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”.base64_encode($url),$url);

}

return $url;

}

然后将主题文件中关于下载链接的地址改为以下代码即可:

<?php echo links_nofollow($url);?>

boke112 导航的下载链接文件就在 inc\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\file.php(其他主题请自行寻找),然后将四个下载链接地址分别改成上述相对应的代码即可,如将第一个下载链接地址:

<?php echo $url1; ?>

改为:

<?php echo links_nofollow($url1);?>

至此,外链及下载地址均变成新的跳转格式(/goto/ base64 加密串),最难得的是原旧跳转格式(/go/?url=外链)依然有效,这个才是值得点赞的。
