解密不了。只能根据网址访问获取进一步数据。有2种情况返回200: 目标网址通过javascript 或 meta 跳转

<meta content="always" name="referrer">
<script>
try{if(window.opener&&window.opener.bds&&window.opener.bds.pdc&&window.opener.bds.pdc.sendLinkLog){window.opener.bds.pdc.sendLinkLog();}}catch(e) {};

var timeout = 0;
if(/bdlksmp/.test(window.location.href)){var reg = /bdlksmp=([^=&]+)/,matches = window.location.href.match(reg);timeout = matches[1] ? matches[1] : 0};setTimeout(function(){window.location.replace("http://www.moe.gov.cn/")},timeout);window.opener=null;</script>

返回302: 这个一般是推广的广告返回，抓取Location就可以了，可以获取关键词。假如要提取网址，再访问Location页面，
