反爬機制：

salt與sign變化加密

解決：js生成

function(e, t) {

var n = e("./jquery-1.7");

e("./utils");

e("./md5");

var r = function(e) {

var t = "" + ((new Date).getTime() + parseInt(10 * Math.random(), 10));

return {

salt: t,

sign: n.md5("fanyideskweb" + e + t + "6x(ZHw]mwzX#u0V7@yfwK")

}

};

salt=t

sign=n.md5("fanyideskweb" + e + t + "6x(ZHw]mwzX#u0V7@yfwK")

t ="" + ((new Data).getTime() + parseInt(10 * Math.random(), 10));

當前時間（毫秒）+ 隨機0-10字串

程式碼實現：
