提示：以下是本篇文章正文内容，下面案例可供参考

一、网站分析

二、代码

扣的js

function fn_o(n) {var t = '';['66', '72', '6f', '6d', '43', '68', '61', '72', '43', '6f', '64', '65']['forEach'](function(n) {t += unescape('%u00' + n)});return String["fromCharCode"](n)
}
function fn_p(t) {t = encodeURIComponent(t)["replace"](/%([0-9A-F]{2})/g, function(n, t) {return fn_o('0x' + t)});try {return btoa(t)// 计算base64} catch (n) {return Buffer['from'](t)['toString']('base64')}
}
function fn_qt(n, t) {for (var e = (n = n['split'](''))['length'], r = t['length'], a = 'charCodeAt', i = 0; i < e; i++)n[i] = fn_o(n[i][a](0) ^ t[(i + 10) % r][a](0));return n['join']('')
}
function fn(t) {var n = undefined;// f || $ != ss = 1079var e, r = +new Date - (s || 0) - 1661224081041, a = [];return undefined === t["params"] && (t["params"] = {}),Object['keys'](t["params"])['forEach'](function(n) {if (n == 'analysis')return false;t["params"]['hasOwnProperty'](n) && a['push'](t["params"][n])}),a = a['sort']()['join'](''),a = fn_p(a),a = (a += "@#" + t["url"]["replace"](t["baseURL"], "")) + ("@#" + r) + ("@#" + 3),e = fn_p(fn_qt(a, 'xyz517cda96efgh')),-1 == t['url']['indexOf']('analysis') && (t['url'] += (-1 != t['url']['indexOf']('?') ? '&' : '?') + 'analysis' + '=' + encodeURIComponent(e)),e
}
// v = fn({
//     baseURL: "https://api.qimai.cn",
//     url: "/indexV2/getIndexRank",
//     params: {
//         "genre": "36",
//         "setting": "0"
//     },
// })
// console.log(v);
