searchid的生成参考代码如下：
function a(e, t) {
for (var n = "".concat(e).split("").reverse(), a = "".concat(t).split("").reverse(), r = [], i = n.length, o = a.length, c = 0, s = i + o - 1; c <= s; c++)
r[c] = 0;
for (var l = 0; l < o; l++)
for (var u = 0; u < i; u++)
r[u + l] += parseInt(n[u], 10) * parseInt(a[l], 10),
r[u + 1 + l] += Math.floor(r[u + l] / 10),
r[u + l] = r[u + l] % 10;
return r.reverse(),
0 == r[0] && r.shift(),
r.join("")
}
function r(e, t) {
for (var n = "".concat(e).split("").reverse(), a = "".concat(t).split("").reverse(), r = n.length, i = a.length, o = 0, c = 0, s = 0, l = 0, u = 0, m = Math.max(r, i); u < m; u++)
c = u < r ? parseInt(n[u], 10) : 0,
s = u < i ? parseInt(a[u], 10) : 0,
l = Math.round(c) + Math.round(s) + o,
n[u] = "".concat(l % 10),
o = l >= 10 ? 1 : 0;
return 1 == o && n.push("1"),
n.reverse().join("")
}
function getSearchId(){
const e = 3;
var t = a(e, "18014398509481984")
, n = a(Math.round(Math.random() * parseInt("4194304", 10)), "4294967296")
, i = new Date
, o = 1e3 * (3600 * i.getHours() + 60 * i.getMinutes() + i.getSeconds()) + i.getMilliseconds();
return r(r(t, n), o)
}
console.log(getSearchId())Python爬虫代码如下：
