抓到post包，分析提交的表单
比较多组数据发现只有salt, lts, sign发生变化(说明页面js脚本对其加密)下面要找到该脚本分析加密过程。因为js启动在点击“翻译”时， 说明事件与该button绑定，找到该元素用事件监听找到脚本
打开后发现有九千多行，但问题不大, ctrl+f搜索指定文字去找变量,找变量要找到最后出现的位置，毕竟要倒退分析
salt等值成了r对象的属性再去找r，r = v.generateSaltSign(n);去找v的该方法的定义
再去找r
找到这个小崽子开始对它分析
var r = function(e) {
var t = n.md5(navigator.appVersion)
, r = "" + (new Date).getTime()//时间戳要注意格式
, i = r + parseInt(10 * Math.random(), 10);//将parseInt(10 * Math.random(), 10)扔入控制台
return {
ts: r,
bv: t, //别忘了他是定值
salt: i,
sign: n.md5("fanyideskweb" + e + i + "Y2FYu%TNSbMCxc3t2u^XT")//md5加密hash处理一下
}
这在0到9中抽一个整形分析完了，扔代码。
