Python和JS反爬之解决反爬参数 signKey

u = function(x) {
var d = x[a(_0x371d("0x14c"))]
 , e = x[a(_0x371d("0x14d"))]
 , _ = x[a(_0x371d("0x14e"))]
 , t = void 0 === _ ? 1 : _
 , n = Math[a("0x82")](10 * Math[a(_0x371d("0x14f"))]())
 , i = (new Date)[a(_0x371d("0x150"))]()
 , o = typeof window !== a("0x4") && window[_0x371d("0x151")]
 , s = o[a(_0x371d("0x152"))]
 , u = a(_0x371d("0x153")) + d.toUpperCase() + a("0x87") + i + a(_0x371d("0x154")) + s + _0x371d("0x155") + n + a("0x89") + e + a(_0x371d("0x156")) + t
 , f = a(_0x371d("0x157"));
return {
   timeStamp: i,
   index: n,
   signKey: (0,
   r[a(_0x371d("0x158"))])(u + f),
   channelId: e,
   sVersion: t,
   WEBdriver: c()
}

a(_0x371d("0x158"));
("default");

function() {
var d = e(7)
 这里面好多代码
        , v = u
        , M = f;

        u = m(u, f, s, c, i[l + 2], 17, 606105819),
        c = m(c, u, f, s, i[l + 3], 22, -1044525330),
 这里面好多代码
