WordPressPaano i-convert ang mga panlabas na link sa mga panloob na link?

Ang panlabas na link ng artikulo ay awtomatikong na-convert sa panloob na link code

Minsan nag-Google kamiSEOAng pagraranggo, pagbabahagi ng ilang mga website o forum sa ibang bansa na na-block ng Chinese network sa WordPress website, ang mga naturang link ay nasa panganib na ma-block.

Samakatuwid, kailangan naming awtomatikong i-convert ang ilang mga panlabas na link sa artikulo sa mga panloob na link.

Ang bentahe ng pag-convert ng mga panlabas na link sa mga panloob na link

  • Pagpapatigas ng seguridad: Pahusayin ang simpleng proteksyon laban sa mga nakakahamak na kahilingan;
  • Jump mode: gamitin ang noscript tag para taasan ang html js jump mode;
  • Jump encryption: Base64 na naka-encrypt na panlabas na chain, tugma sa hindi naka-encrypt na jump;
  • Ipinagbabawal na isama ang: Nagdagdag ng pahayag ng META na nagbabawal sa mga spider ng search engine na isama at makuha;
  • Ipinagbabawal na Paggamit: Ipagbawal ang ibang mga site sa paggamit ng aming mga pahina sa pag-redirect.

Hakbang 1: I-upload ang file sa root directory ng website

Mayroong 2 bersyon ng code na awtomatikong nagko-convert sa mga panlabas na link ng mga artikulo sa WordPress sa mga panloob na link:

  1. bersyon ng PHP
  2. bersyon ng JS

bersyon ng PHP

I-save ang sumusunod na PHP code bilang go.php at i-upload ito sa root directory ng website.

<?
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=="chenweiliang" ) {
 $t_url="https://www.chenweiliang.com/";
} elseif($t_url=="etufo") {
 $t_url="https://www.etufo.org/";
}
//数据处理
if(!empty($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'];

Pakitandaan ang pagbabago://Ang jump page na ito ay hindi pinapayagang gamitin para sa mga domain name maliban sa site na ito, mangyaring baguhin ang chenweiliang.com sa iyong sariling domain name

Alin ang mas maganda, PHP o JS?

Ang mga pag-andar ng bersyon ng PHP at ang bersyon ng JS ay pareho, ang pagkakaiba ay:

  • Ang bersyon ng PHP ay dynamic at bahagyang na-load ang server;
  • At ang bersyon ng JS ay nangangailangan ng browser na suportahan ang JS upang gumana nang maayos,
  • Ngunit ngayon, sinusuportahan ito ng karamihan sa mga browser!

Tandaan: Kung ang jump code ng pagsubok na bersyon ng JS ay hindi wasto, gamitin ang jump code ng PHP.

Hakbang 2: Magdagdag ng code sa function.php file

Pagkatapos i-upload ang jump page, ang susunod na hakbang ay idagdag ang external link jump code sa function.php file ng WordPress theme.

2-to-1 code:

  • 1) Tumalon ang panlabas na link nang walang pag-encrypt
  • 2) External link jump base64 encryption [inirerekomenda]

Tumalon ang panlabas na link nang walang pag-encrypt

// 外链跳转无加密go.html?url
add_filter('the_content','link_to_jump',999);
 function link_to_jump($content){
 preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$content,$matches);
 if($matches){
 foreach($matches[2] as $val){
 if(strpos($val,'://')!==false && strpos($val,home_url())===false && strpos($val,'chenweiliang.com')===false && strpos($val,'ufo.org.in')===false && strpos($val,'etufo.org')===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\"", "rel=\"nofollow\" target=\"_blank\" href=\"go.html?url=$val\" ",$content);

}
 }
 }
 return $content;
 }

External link jump base64 encryption [inirerekomenda]

// 外链跳转base64加密go.html?url
 add_filter('the_content','link_to_jump',999);
 function link_to_jump($content){
 preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$content,$matches);
 if($matches){
 foreach($matches[2] as $val){
 if(strpos($val,'://')!==false && strpos($val,home_url())===false && strpos($val,'chenweiliang.com')===false && strpos($val,'ufo.org.in')===false && strpos($val,'etufo.org')===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\"", "rel=\"nofollow\" target=\"_blank\" href=\"go.html?url=" .base64_encode($val). "\" ",$content);

}
 }
 }
 return $content;
 }

Hindi kasama ang pagtukoy ng isang panlabas na link na domain name mula sa hindi awtomatikong pag-convert sa isang panloob na link (pangalan ng domainwhitelist):

&& strpos($val,'你的域名')===false

hinaharangan ng robots.txt ang mga gagamba

Upang maiwasan ang pag-crawl ng mga spider ng search engine sa mga jump link, maaari kaming magdagdag ng mga panuntunan upang pagbawalan ang mga spider ng search engine sa pag-crawl sa robots.txt file:

User-agent: *
Disallow: /go.html?url=*
Disallow: /go.php?url=*
