js逆向七麦数据

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 || $ != s
    s = 1079
    var 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);
