某点数据k值计算

const axios = require('axios');

//-----------------------conent参数的生成---------------------------------------------
//生成conent的第一个函数
function one(s, t, path, e) {
    return [s, t, e, path].join("(&&)")
}

//生成content的第二个函数,two的返回值为one函数第一个参数s
//这个函数的作用是直接把传进来的参数对象的值取出来，全部推送到一个列表,然后后排序和join()
function two(t) {
    var r = [];
    for (var c in t) {
        r.push(t[c]);
    }
    r.sort()
    return r.join("")
}

//生成one函数的第二个参数t
function generateT() {
    return parseInt((new Date).getTime() / 1e3) - 655876800
}

//-----------------------conent参数的生成---------------------------------------------

// 匿名函数y
function y(content, t, e) {
    for (var a = Array.from(content), n = Array.from(t), r = a.length, o = n.length, c = String.fromCodePoint, i = 0; i < r; i ++)
        a[i] = c(a[i].codePointAt(0) ^ n[(i + e) % o].codePointAt(0));
    return a.join("")
}

//y函数的调用链t和e都为固定值，剩余的的就是看content是怎么计算的
var t = "17*cmvw0$)";
var e = 10;

//content的计算步骤
var path = "/v1/rank";

// var content = one(two(two_t), generateT(), path, "dd")
// console.log(content);
//
// y_res = y(content, t, e);
// console.log(y_res)
//
// base64_result = Buffer.from(y_res, "utf-8").toString("base64")
// console.log(base64_result)
