京东的h5st看着吓人一打开f12就显示

本页面由 京东-主站前端团队 开发维护                       -- JDC

其实过程很明显，经过了6,7个平坦流才可以拿到结果

主要细心一点，相信你一定也可以


1.定位位置 搜h5st能打的地方都打上断点 下滑看看在哪里断住

2.参数分析

由于当前的时间点可以发发现第1段和第7段其实用了一种形式的转换

第2.3.4段先固定，当前文章不做分析

主要要解决的就是第5,8,9段后你就可以拿到数据了

3.怎么能解决VMP的纯算呢？最简单的办法就是跟栈，找到主要的位置插装

为了细致的知道所有内容，本文建议在跟栈在call的地方和平坦流位置进行插装，可以跟栈时候详细的看到所有内容

下面直接正文

o = {
    "page": 2,
    "pagesize": 25,
    "area": "1_72_0_0",
    "source": "pc-home"
}
没有魔改的SHA256算法
r = {
    "appid": "www-jd-com",
    "body": "6a18875f3dd265575c69fe1bd6388b05d78387d7fe86518a660a1201eb2f2714",
    "clientVersion": "1.0.0",
    "client": "pc",
    "functionId": "pc_home_feed",
    "t": 1726120971200
}
window.PSign.sign(r)

可以先查看入参和结果在这里是一个异步操作，这里等待的时候是pending，完成的时候是fullfill就可以看到h5st的生成

接下来进行跟栈

第一层
 

进入到for (var a, s, c, i, u, l = n, f = o, g = [], p = 1030; ; ) vmp
插装分析 找到 call 堆栈 
'case',f[p],'g-->',g
重点过程
[
    {
        "key": "appid",
        "value": "www-jd-com"
    },
    {
        "key": "body",
        "value": "6a18875f3dd265575c69fe1bd6388b05d78387d7fe86518a660a1201eb2f2714"
    },
    {
        "key": "client",
        "value": "pc"
    },
    {
        "key": "clientVersion",
        "value": "1.0.0"
    },
    {
        "key": "functionId",
        "value": "pc_home_feed"
    },
    {
        "key": "t",
        "value": 1726120971200
    }
]
case 62 时候(2)[ƒ, te] 生成第8部分
te就是这部分内容
{
    "_storagetokenKey": "WQ_dy_tk_s_b5216_4.7",
    "_storageAlgnKey": "WQ_dy_algo_s_b5216_4.7",
    "_storageFpKey": "WQ_vk1_b5216_4.7",

    "algos": {},
    "_version": "4.7",

}
生成结果是：

当发现是通过函数来执行的时候如果通过日志没法清楚地知道里面的过程,就是点进去跟栈，接下来进入到第二层

跟进进入
key: $,
	value: function() {
		for (var e, t, a, s, c, i = n, u = o, l = [], h = 821; ; )
这个vmp
'case',u[h],'l-->',l
观察日志
case 28 l--> [{…}]
case 45 l--> (5) [ƒ, undefined, {…}, null, 2]看入参
{
    "sua": "Windows NT 10.0; Win64; x64",
    "pp": {},
    "extend": {
        "wd": 0,

}
这个函数    var zw = function(e, t, r) {
        return Dw(Mw.JSON.stringify, null, arguments)
    }
得到结果
'{\n  "sua": "Windows NT 10.0; Win64; x64",\n  "pp": {},\n  "extend": {\n    "wd": 0,\n    "l": 0,\n    "ls": 5,\n    "wk": 0,\n    "bu1": "0.1.4",\n    "bu2": -1,\n    "bu3": 35,\n    "bu4": 0,\n    "bu5": 0,\n    "bu6": 23,\n    "bu7": "",\n    "bu8": 0\n  },\n  "pf": "Win32",\n  "random": "jRHedsNrt_x",\n  "v": "h5_file_v4.7.4",\n  "canvas": "d98dce374ca197fa2c2826390808089d",\n  "webglFp": "a3e19bf2c47e1ad07028cb74d487f910",\n  "ccn": 8,\n  "fp": "m95mtygin5m66mm6"\n}'

case 93 l-->  把 "_M6Y?dvfN40VMF[X"  parse一下
parse: function(e) {
	return d.parse(unescape(encodeURIComponent(e)))
}
结果{

继续case93 拼接字符串[01,02,03,04,05,06,07,08]
'0102030405060708'
case 93
l[l.length - 2]['parse']('0102030405060708')

迷糊了不知道是哪个方法的可以去打印$_可以观察出来到底是什么方法

这样在看日志的时候就会大概可以看出到底是运行的什么算法

生成了完整的h5st

跟进去看看
value: function(e, t) {
    for (var a, s, c, i, u, l, h, f, g, p, v, b, d = n, k = o, y = [], w = 536; ; )
这个堆栈
同样的方法
'case',k[w],'y-->',y

case 59 y-(4) [ƒ, undefined, 1726126134444, 'yyyyMMddhhmmssSSS']
这个就是要生成第一段 通过nx
1726126134444--->20240912152854444

有个坑
case 66 y--> 20240912152854444 + 47 = 2024091215285444447

接下来会有一个test函数
case 32:
    y[y.length - 7] = d.call(y[y.length - 7], y[y.length - 6], y[y.length - 5], y[y.length - 4], y[y.length - 3], y[y.length - 2], y[y.length - 1]),
    y.length -= 6;

传参数有

    ƒ test(tk,fp,ts,ai,algo),//接口来的
    {

进入VM

(function anonymous() {
return function test(tk,fp,ts,ai,algo){
    var rd='q1sbyQS0w5iV';
    var str="".concat(tk).concat(fp).concat(ts).concat(ai).concat(rd);
    return algo.HmacMD5(str,tk);}
    }
)

可以发现他会随机生成六种算法HmacMD5，HmacShA256, MD5, SHA256....所有算法均被魔改

最主要的就是能抠出来他的算法，抠出来你就已经成功一大半了

魔改HmacMD5

toString后 
'2663ffb9b684fd5f22c34a705d63889d'

继续到了

看一看f 是什么
到了这个vmp
同样的方法插装分析
key: u,
value: function(e, t) {
    for (var a, s, c, i, u = n, l = o, h = [], f = 272; ; )
'case',l[f],'h-->',h

注意打断点74 要打两层

对这个做运算不知道是啥 断点忘打了
就跟一下栈，你会发现是什么算法
结果是

然后tostring 此段为第5段结果

结果为'8929557aa3e1087dd2143db6d4bea789'

进入这个vmp
key: l,
value: function(e, t) {
	for (var a, s, c, i, u, l, h = n, f = o, g = [], p = 355; ; )
先有一个filter 
过滤 appid 和 functionId
提取
['appid:www-jd-com', 'functionId:pc_home_feed']
join
'appid:www-jd-com&functionId:pc_home_feed'

"2663ffb9b684fd5f22c34a705d63889dappid:www-jd-com&functionId:pc_home_feed2663ffb9b684fd5f22c34a705d63889d"
然后
case 30:
		null != g[g.length - 2] ? (g[g.length - 3] = h.call(g[g.length - 3], g[g.length - 2], g[g.length - 1]),
		g.length -= 2) : (l = g[g.length - 3],
		g[g.length - 3] = l(g[g.length - 1]),
跟一下看看是MD5 破案了
 var f = l.MD5 = o.extend({
                    _doReset: function() {
                        this._hash = new a.init([1732584193, 4023233417, 2562383102, 271733878])
                    },
变成

toString'dd8668be86d1090ed5b0f36ce63f5869'
这个就是a9的值

最后把这些值拿一下

致辞所有参数完毕，看看是如何拼接的

最后把这些值拿一下
