前言：
在WordPress中，我们经常需要将外部链接转换为内部链接，以提高用户体验和搜索引擎优化，本教程将向您展示如何使用代码实现这一功能，无需使用任何插件。
首先，在自己的wordpress网站的根目录下新建一个go.php文件，在go.php里面输入以下代码
<?php
/*自动跳转页面
*@copyright (c) Emlog All Rights Reserved */
//自定义跳转地址
$cars = array(
array("qcloud",'https://curl.qcloud.com/ogHI5jPB'),
array("aliyun",'https://www.aliyun.com/minisite/goods?userCode=y7af6jip'),
);
if(strlen($_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
$t_url = htmlspecialchars(preg_replace('/^url=(.*)$/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
foreach($cars as $k=>$val){
if($t_url==$val[0] ) {
$t_url = $val[1];
$t_vip = 1;
}
}
//数据处理
if(!empty($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'];
}
?>

记得把里面的ICO图标地址换成自己的，还有已个文字广告。
使用方法：保存之后，则外链跳转形式为： {本站地址}/go?{外链地址}
使用:在添加外链的时候，只要给外链加上统一的跳转前缀：http://网站地址/go? 即可。
为了防止蜘蛛爬行，在 Robot s 禁止所有蜘蛛爬行 /go?url 目录！
Disallow: /go/ Disallow: /go?url
下面是怎么把文章里的外链转过来的代码，需要把代码加到functions.php里
/*自动给文章的外部链接添加go属性开始*/
add_filter('the_content','link_jump',999);
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()."/go/?".base64_encode($val)."\" rel=\"nofollow\"",$content);
}
}
}
return $content;
}
// 自动给文章的外部链接添加go属性结束
点击测试转换后的链接，确保它们已成功转换为内部链接并在当前窗口中打开。
