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;

$url=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’http://\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.$t_url;

} else {

$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。
