js加密
function ms(t) { var s = { auth_code: "auth_code=zXOJEnesUft97" }; s.time = (new Date).getTime(), s.time = parseInt(s.time / 1e3), $cookies.get("token") && (t.token = "" + $cookies.get("token")), t.time = "" + s.time, t = function(t) { var s = new Array, a = 0; for (var i in t) s[a] = i, a++; var e = s.sort(), n = {}; for (var i in e) n[e] = t[e]; return n } (t); var a = ""; for (var i in t) a += i + "=" + t + "&"; return t.sign = v()(s.auth_code + "&" + a), ps.a.stringify(t) }这个sign是怎么算出来的?
