WordPress adds external link go jump function

Method 1: pure code implementation

First, create a go.php file in the root directory of your wordpress website, and enter the following code in go.php

<?php

$t_url = preg_replace('/^url=(.*)$/i','$1',$_SERVER["QUERY_STRING"]);

if(!empty($t_url)) {

preg_match('/(http|https):\/\//',$t_url,$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://mybj123.com/';

$title='参数错误，正在返回首页...';

}

} else {

$title='参数缺失，正在返回首页...';

$url='https://www.mybj123.com/';

}

?>

How to use: After saving, the external link jump form is: {site address}/go.php?{external link address}

Use: When adding an external link, just add a unified jump prefix to the external link: http://website address/go.php?.

In order to prevent spiders from crawling, all spiders are prohibited from crawling the /go?url directory in Robots!

1 2	`Disallow: /go/` `Disallow: /go?url`

Method 2: Plug-in implementation

Some plug-ins can also achieve this external link jump

1. Simple URLs plug-in: easy to set up, just need to set the suffix and target page in the background

2. Link-Hopper plug-in: the base address of the jump link can be set at will

3. Pretty Link Lite plug-in: the background function is very powerful, and there is also a Pro version, but it requires money. It can be used to make a short URL , like t.cn and bit.ly.

4. Affiliate Link Cloaking plug-in: Affiliate link conversion tool , used to promote your Taobao customers and other hidden links, you can use it, with statistics function.

5. WP No External Links plug-in: This one can automatically convert the external links in the blog into internal links, such as http://www.baidu#com, it will be displayed as http://www.mybj123#com/goto/ http://www.baidu#com (# is .), you can try to use this plugin to prevent weight loss.

6. Go Codes plug-in: It is as simple as the previous wordpress external link jump link plug-in setting, with statistics function.

Note: You can try it yourself whether the plug-in is used or not. I won’t explain too much here, and I won’t be responsible for the right or wrong of the plug-in.

Method 3: Netizen recommendation

Create go.php, write:

<?php

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

$t_url = preg_replace('/^url=(.*)$/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=="zhangge" ) {

$t_url="//zhangge.net";

} elseif($t_url=="baidu") {

$t_url="https://www.baidu.com/";

}

//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

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'];

}

?>

//延时1S跳转，可自行修改延时时间

找到模板的functions.php文件添加：

/*文章外链跳转伪静态版

此为新窗口打开，如不想要直接删除下面的tar _ ank（安全问题不能打出来）

*/

add_filter('the_content','link_jump',999);

function link_jump($content){

preg_match_all('//',$content,$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.php?".base64_encode($val)."\" rel=\"nofollow\" target='_blank' ",$content);

}

return $content;

}

nginx 伪静态设置（跳转方式为/go/）：

# 外链跳转伪静态 php版本

rewrite ^/go/(.*)$ /go.php?url=$1 last; #注意go.php的实际路径，默认为网站根目录

以上代码增加了跳转美化效果，代码中已经用 base64 将源链接加密，并且加上了 nofollow，但恐怕蜘蛛还是能爬行，在 Robot s 禁止所有蜘蛛爬行 /go?url 目录！
