WordPress:利用go.php给网站添加外链跳转效果

这是魔效源码在网上发现的一个访问外链实现自动进行内部跳转效果的代码,在原来的基础上做了一些修改,这个代码不仅让网站的用户体验度增加,而且更加显得正规化,还可以避免自己网站权重的流失,符合SEO优化规则,当然有些部分主题是自带有外链跳转效果的就不说了。 下面直入主题

WordPress纯代码外链跳转效果的实现步骤

1、新建go.php文件

新建 go.php 文档,添加以下PHP代码,并且上传到网站根目录。

<?php
/**
 * 自动跳转页面
 * @copyright (c) Emlog All Rights Reserved
 */
//自定义跳转地址
$cars = array(
    array("moxiao",'http://www.moxiaoseo.com/'),
    array("moxiao",'http://www.moxiaoseo.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'];
}
?>

2、使用方法-手动添加

可以在添加外链的时候手动添加跳转,同时跳转样式可以自行修改。

可用的外链跳转形式为: {本站地址}/go.php?{外链地址} 或 {本站地址}/go.php?url={外链地址}

在文章添加外链的时候,只要按照以上格式添加即可

3、自动识别外链自动添加跳转

在functions.php文件中加入以下代码,这样就可以自动进行外链替换,无需第2点说到的必须以人工方式替换…

//给外部链接加上跳转  
add_filter('the_content','the_content_nofollow',999);  
function the_content_nofollow($content)  
{  
    preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$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)){  
                $content=str_replace("href=\"$val\"", "href=\"".home_url()."/go/?url=$val\" ",$content);  
            }  
        }  
    }  
    return $content;  
}
// 下载外链跳转
 function links_nofollow($url) {
     if(strpos($url,'://')!==false && strpos($url,'guihet.com')===false && !preg_match('/(ed2k|thunder|Flashget|flashget|qqdl):\/\//i',$url)) {
 $url = str_replace($url, home_url()."/go/".base64_encode($url),$url);
      }
     return $url;
 }

要查看实际效果点击本站之前文章内的任意一个外站的链接即可。
