wordpress文章评论超链接转内链go有效方法

对于搜索,网络蜘蛛最怕爬你的网站时,外链超多,这样慢,且不利于收录。

默认wordpress对于外链添加了nofollow标记,意思告诉蜘蛛别爬我。

所以解决方法目前大家都是把外链转成内链,这样说可能你还没看明白。

比如,你文章中存在链接 https://www.qq.com/

点击后,通过本站 /goto/xxxbase64xxx,跳转到www.qq.com

并且期间展示一个友好的跳转界面,如图

接下来,我们手工代码编辑来弄。

第一步

在博客主目录下,创建一个文件夹,命令为go

然后新建一个文件index.php

编辑内容如下代码,这个就是上图的跳转页代码了

<?php
/**
* WordPress外链go跳转页面 - https://www.dujin.org/12762.html
* @copyright (c) Emlog All Rights Reserved
*/
//自定义跳转地址
$cars = array(
array("qcloud",'http://www.qcloud.com/redirect.php?redirect=1001&cps_key=8558139aea55e95d71f488081ba44577'),
array("upyun",'https://www.upyun.com/league'),
array("trustutn",'http://c.trustutn.org/s/aeink.com'),
array("gfvps",'https://www.gfvps.cn/page.aspx?c=referral&u=9023'),
array("360scan",'http://webscan.360.cn/index/checkwebsite/url/www.aeink.com')
);

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'];
}

}
}, 970)
}
</script>
<script>alertSet("<?php echo $title;?>");</script>
</body>
</html>

第二步

找到你当前使用的主题目录,通常路径为

wp-content/themes/你的主题名称/functions.php

在functions.php中追加下面代码,此代码主要是替换已有链接为你的内链。

支持文章,评论作者链接和评论内容链接的替换。

//WordPress外链新窗口打开并使用php页面go跳转
add_filter('the_content','link_jump',99); // 文章正文外链转换
add_filter('get_comment_text', 'link_jump'); // 评论内容的链接转换
//add_filter('comment_text','link_jump',99); // 新版本评论根本无效
add_filter('get_comment_author_link','link_jump',99); // 访客的链接转换
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()."/goto/".base64_encode($val)."\"",$content);
			}
		}
	}
	return $content;
}

第三步

这是为了能成功跳转

编辑伪静态nginx

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

Apache服务器修改根目录.htaccess文件,添加以下代码

RewriteRule ^go/(.*)$ /go/$1 [L]
RewriteRule ^goto/(.*)$ /go.php?url=$1 [L]

最后编辑robots.txt文件告诉各搜索引擎,排除爬行以下两个目录

robots一般在你网站根目录下,没有的话,自创内容如下

Disallow: /wp-admin/
Disallow: /goto/
Disallow: /go/
Sitemap: https://www.freebasic.cn/sitemap.php

说明一下,

add_filter('comment_text','link_jump',99);

comment_text 过滤评论字符和网址 使用方法网络上的教程都不对,不要浪费时间。
改用

add_filter('get_comment_text', 'link_jump');
