源码介绍
WordPress防红系统跳转页面和引导跳转页面gophp-html源码美化版，双端自适应。自动文章内的外链加入加密的跳转链接，其他网站也可以用。
使用教程：
1、网站根目录新建go文件夹
2、go目录里新建index.php
3、index.php里的代码如下:
<?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'];
}
?>

function alertSet(e) {document.getElementById("js-alert-box").style.display = "block", document.getElementById("js-alert-head").innerHTML = e;var t = 3,n = document.getElementById("js-sec-circle");document.getElementById("js-sec-text").innerHTML = t, setInterval(function() {//禁止其他网站调用此跳转//var MyHOST = new RegExp("<?php echo $_SERVER['HTTP_HOST']; ?>");//if (!MyHOST.test(document.referrer)) {// location.href="http://" + MyHOST;//}if (0 == t) location.href = "<?php echo $url;?>";else {t -= 1, document.getElementById("js-sec-text").innerHTML = t;var e = Math.round(t / 5 * 735);n.style.strokeDashoffset = e - 735}}, 970)

<script>alertSet("<?php echo $title;?>");</script>
</body>
</html>4、在functions.php里加下面的代码：（注部分主题可能不是这个请自己区别）
/*自动给文章的外部链接添加nofollow属性开始*/
add_filter('the_content','link_jump',999);function link_jump($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nofollow属性结束
/*WordPress外链自动新窗口打开并添加nofollow属性*/
add_filter( 'the_content', 'cn_nf_url_parse');
function cn_nf_url_parse( $content ) {$regexp = "<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>";if(preg_match_all("/$regexp/siU", $content, $matches, PREG_SET_ORDER)) {if( !empty($matches) ) {$srcUrl = get_option('siteurl');for ($i=0; $i < count($matches); $i++){$tag = $matches[$i][0];$tag2 = $matches[$i][0];$url = $matches[$i][0];$noFollow = '';$pattern = '/target\s*=\s*"\s*_blank\s*"/';preg_match($pattern, $tag2, $match, PREG_OFFSET_CAPTURE);if( count($match) < 1 )$noFollow .= ' target="_blank" ';$pattern = '/rel\s*=\s*"\s*[n|d]ofollow\s*"/';preg_match($pattern, $tag2, $match, PREG_OFFSET_CAPTURE);if( count($match) < 1 ) $noFollow .= ' rel="nofollow" '; $pos = strpos($url,$srcUrl); if ($pos === false) { $tag = rtrim ($tag,'>');$tag .= $noFollow.'>';$content = str_replace($tag2,$tag,$content);}}}}$content = str_replace(']]>', ']]>', $content);return $content;
