文章搭配视频地址：挖洞遇到验证码那些事
# 正文
输入手机号码与账号密码登录的接口都有滑块。区别在于账号密码登录的时候有个加盐密码。流程比手机号码的接口复杂一下，为了省时间。此文章便是根据手机号码的接口去写的，毕竟咱的目的是过滑块嘛。
## 发包逻辑分析
每次刷新验证码，都会发四个数据包下来。第一个数据包用于请求图片。图片链接的拼接就是urlParams加上imgs的值。
第三个数据包是背景图
第四个数据包是缺口图片
正确拼接验证码，短信验证码发送成功
captcha_signature在刷新验证码发下来的数据包里面的sign参数。
captcha_phrase和captcha_ticket在getTicket接口从服务器返回回来的，captcha_phrase是缺口，如果缺口对齐失败的话captcha_ticket是获取不到的。所以得先把getTicket接口的参数补齐拿到ticket。
getTicket的前五个参数直接从getPreHandle接口返回的urlParams获取。
phrase直接用搜索大法就能搜到关键位置
phrase: (x) + ";" + inity + ";" + opt.width + ";" + opt.height
x是缺口识别的x轴,opt.width和opt.height是固定的值
inity也是直接在js文件一搜就能拿到他的关键代码。data.data.inity在getPreHandle接口里面的inity。这段代码就是取那个inity相除相乘再拼接到phrase里头
inity = (data.data.inity / 195 * opt.height);
x直接就是缺口识别然后减去15(因为图片实际大小跟他在网页上面的大小不一样)，懒得缩小了。因为通过训练相同的图片跟缺口其x就相差15，直接减更方便(懒人做法)
图片缺口识别代码：
def detect_captcha_gap(bg, tp): ''' bg: 背景图片 tp: 缺口图片 return:空缺距背景图左边的距离 ''' # 读取背景图片和缺口图片 bg_img = cv2.imread(bg) # 背景图片 tp_img = cv2.imread(tp) # 缺口图片 # 识别图片边缘 bg_edge = cv2.Canny(bg_img, 100, 200) tp_edge = cv2.Canny(tp_img, 100, 200) # 转换图片格式 bg_pic = cv2.cvtColor(bg_edge, cv2.COLOR_GRAY2RGB) tp_pic = cv2.cvtColor(tp_edge, cv2.COLOR_GRAY2RGB) # cv2.imwrite("bg_style.png",bg_pic) # 保存背景轮廓提取 # cv2.imwrite("slide_style.png",tp_pic) # 保存滑块背景提取 # 缺口匹配 res = cv2.matchTemplate(bg_pic, tp_pic, cv2.TM_CCOEFF_NORMED) min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(res) # 寻找最优匹配 th, tw = tp_pic.shape[:2] tl = max_loc # 左上角点的坐标 # 返回缺口的左上角X坐标 br = (tl[0] + tw, tl[1] + th) # 右下角点的坐标 cv2.rectangle(bg_img, tl, br, (0, 0, 255), 2) # 绘制矩形 cv2.imwrite("result_new.png", bg_img) # 保存在本地 # 返回缺口的左上角X坐标 return tl[0] x = detect_captcha_gap("bg.jpg","tp.jpg")-15
mobile加密就是一个rsa加密，没有任何混淆跟难点。
验证码校验接口还有个hexin-v参数
hexin-v硬扣
校验验证码的数据包里面有个加密的header参数hexin-v,他跟cookie的v是一模一样的。有两种方法可以找到关键加密位置，第一种是headers hook,第二种是cookie hook。
cookie hook代码：
(function () { 'use strict'; var cookieTemp = ""; Object.defineProperty(document, 'cookie', { set: function (val) { console.log('Hook捕获到cookie设置->', val); if (val.indexOf('v') != -1) { debugger; } cookieTemp = val; return val; }, get: function () { return cookieTemp; } }); })();
在控制台输入hook的代码
断点断了下来。回溯堆栈找到关键代码加密的地方
w函数便是设置cookie的函数，r就是v加密生成返回的值。那么qn.update()就是v生成的函数了。把断点下到qn.update()那一行然后刷新。由于这个网站的js文件是动态生成的，所以需要重新进入新的js文件在qn.update()那一行重新下个断点刷新。
断点断下之后进入qn.update()看看里面写了啥
进入到qn.update()函数内部可以看出他返回了另外一个函数的返回值。
把断点断到R函数这一行进入到R函数内部。
R函数往E对象里面压入一堆值。找找E在哪里生成的。
E对象是在b函数里面被赋值的，但因作用域的原因，他并不是在这里声明的，E声明的地方还得往上面去找。
在945行找到E声明的地方，同时也发现了这一段大的函数是一个自执行的函数。
开始扣代码，就只扣需要的代码，R()是v加密后的值，R函数里面有E对象，E对象是在b函数里面被实例化的。b函数也扣下来，b函数里面调用了C函数。C函数也一并扣下来。因为E对象是全局作用域，其声明的代码在几个函数的外面。
var o = r[40], i = r[37], u = e[26], c = e[121], s = parseInt(Kn(n[80], e[122], t[135]), t[67]), f = n[94], v = r[59], l = e[74], p = n[53], d = parseInt(t[29], t[62]), h = parseInt(n[68], n[134]), g = n[135], m = parseInt(e[123], n[51]), w = parseInt(n[136], e[58]), I = parseInt(e[124], t[136]), _ = parseInt(e[125], e[79]), y = parseInt(n[137], n[134]), A = parseInt(e[126], t[67]), E; function C() { var r = Wn.getCookie(On) || $n.get(Pn); if (r && r[t[59]] == parseInt(n[138], t[62])) { var e = Qn.decode(r); if (e && (E.decodeBuffer(e), E[o] != n[29])) return } E[o] = Gn.random() } function b() { var t = e[31] , a = parseInt(e[127], e[26]) , o = r[52] , u = parseInt(e[128], e[26]); E = new Un([u, u, u, u, t, t, t, o, a, a, a, a, a, a, a, u, a, t]), E[i] = Gn.serverTimeNow(), C(), E[_] = Dn, E[A] = xn, E[y] = n[29], E[c] = Gn.strhash(navigator.userAgent), E[w] = Yn.getBrowserFeature(), E[s] = Yn.getPlatform(), E[f] = Yn.getBrowserIndex(), E[v] = Yn.getPluginNum() } function R() { var n = Y; E[y]++, E[i] = Gn.serverTimeNow(), E[u] = Gn.timeNow(), E[_] = Dn, E[l] = Jn.getMouseMove(), n = q, E[p] = Jn.getMouseClick(), E[d] = Jn.getMouseWhell(), E[h] = Jn.getKeyDown(), E[g] = Jn.getClickPos().x, E[m] = Jn.getClickPos().y; var t = E.toBuffer(); return Qn.encode(t) } console.log(R())
代码运行报错，r未定义。那么e,t,n是否也是未定义。在浏览器运行一下看看是什么呢
在控制台打印r,e,t,n。发现他们都是大数组。直接扣下来就行了

运行报window，document未定义。在开头定义一下为空对象
var window ={}
var document={}
运行报Kn未定义
把断点下到报错代码那一行，进去Kn函数内部
function Kn() { var r = arguments[t[31]]; if (!r) return t[33]; for (var a = e[32], o = n[25], i = n[29]; i < r.length; i++) { var u = r.charCodeAt(i) , c = u ^ o; o = u, a += n[27].fromCharCode(c) } return a }
运行报错Y未定义。
浏览器查看Y是字符串“1”，直接在代码中写固定就行
报这个错的原因是因为没有调用b函数，在R函数的开头调用运行一下b函数。
对象实例化Un函数是未定义的。去浏览器扣。
浏览器扣下来的Un函数
var Un = function() { var a = r[44] , o = r[45]; function i(a) { this[e[53]] = a; for (var o = r[40], i = a[t[59]]; o < i; o++) this[o] = n[29] } return i[r[46]][r[47]] = function() { for (var o = t[60], i = this[n[47]], u = [], c = -n[30], s = n[29], f = i[Kn(r[48], t[61])]; s < f; s++) for (var v = this[s], l = i[s], p = c += l; u[p] = v & parseInt(a + o, t[62]), --l != e[27]; ) --p, v >>= t[62]; return u } , i[A + E][Xn(e[54], r[49], x)] = function(a) { for (var i = t[63], u = this[T + o + i], c = t[35], s = n[29], f = u[Xn(n[48], r[50])]; s < f; s++) { var v = u[s] , l = r[40]; do { l = (l << r[51]) + a[c++] } while (--v > n[29]);this[s] = l >>> e[27] } } , i }()
运行报Xn未定义，分析代码的作用是把函数赋给对象，那么i后面跟着的肯定是字符串，把函数赋给某某对象原型链下面的某个属性。
替换即可。
运行报Gn未定义，直接进入Gn.serverTimeNow()函数内部查看写了什么。
浏览器扣下来的代码，看看这段代码有什么作用。
function cn() { var n = (s, u, new v[84]); return typeof TOKEN_SERVER_TIME == x + T + C ? I[27] : (time = parseInt(TOKEN_SERVER_TIME), time) }
cn函数有一个三元表达式，TOKEN_SERVER_TIME是数值，x + T + C是"undefined"，TOKEN_SERVER_TIME == x + T + C 是false
所以执行(time = parseInt(TOKEN_SERVER_TIME),time)
这段函数的整体意思是将TOKEN_SERVER_TIME取整赋值给time，再把time值返回。
E[i] = Gn.serverTimeNow()直接改写成E[i] = parseInt(TOKEN_SERVER_TIME)
运行代码报错TOKEN_SERVER_TIME未定义，在浏览器搜索TOKEN_SERVER_TIME。
在第一行就可以看到TOKEN_SERVER_TIME。直接扣下来
运行报错Wn未定义。这段C函数代码要是直接去扣就入坑了，先看看这个C函数有什么作用。
第一行代码就是取cookie名为v的值，如果没取到cookie的v值就去取headers的"hexin-v"值。
var r = Wn.getCookie(On) || $n.get(Pn);
一般情况下都不是第一次运行，那么他就会取得到前面cookie的v值。那么下面的if判断就会成立，就会执行。但是我们总不可能每次运行代码都去取他前面的cookie，那实在是太复杂了。假设，我是说假设。假设我每一次进去这个网站都是第一次，都取不到cookie的v值和headers的hexin-v。那么这段代码又是有什么样的作用呢。
cookie的v和headers的hexin-v都取不到值的话那么if里面的就是null。就直接执行后面的代码
最后C函数的代码就是直接改写成E[o] = Gn.random()
运行报错,直接扣Gn.random()
function rn() { var n = sn; return n = G, Math.random() * parseInt("11111111111111111111111111111111", 2) >>> 0 }
C函数可以值改写成
E[o] =Math.random() * parseInt("11111111111111111111111111111111", 2) >>> 0
Dn报错
Dn是数值0
xn未定义
xn是数值3
报了Gn的错。分析这段代码就是把浏览器指纹ua传进了strhash函数。可以直接取最后的值写固定。
E[c] = 自己浏览器头strhash后的值
后面的报错都是这几个值未定义。
getBrowserFeature—>获得浏览器特性
getPlatform—>获取浏览器平台
getBrowserIndex—>获取当前网页所在浏览器的索引
getPluginNum—>获取当前网页或浏览器环境中已安装或可用的插件数量。
至于改写的话直接取最后的值就行了
b函数都改完之后到R函数报错了。Gn.serverTimeNow()在b函数就已经扣过了
Gn.serverTimeNow()—>parseInt(TOKEN_SERVER_TIME)
Gn.timeNow()未定义
进入Gn.timeNow()函数内部是个on函数
on函数的作用就是取当前时间戳除以1000再无符号右移0位
改写后的代码
E[u] = Date.now()/ 1000
后面的代码都是未定义的
Dn是数值0，n是字符串"DOMMous"
getMouseMove—>获取鼠标当前的横坐标和纵坐标
getMouseClick—>获取鼠标点击时的横坐标和纵坐标，以及所点击的按钮
getMouseWhell—>获取滚轮事件的信息
getKeyDown—>获取按键事件的信息
getClickPos—>获取鼠标点击的坐标，然后进行相应的操作，比如记录点击位置或者根据点击位置执行特定的逻辑。
直接取最后运行完的值
运行Qn.encode未定义
进入函数内部Qn对象总共有4个方法，直接把Qn对象补齐.
var Qn; !function(a) { var o = e[55] , i = n[49] , u = n[50] , c = r[52]; function s(a) { var o, i, u; o = i = u = t; var c, s, f; c = s = f = r; var v, p, d; v = p = d = e; var h, g, m; h = g = m = n; for (var w = g[29], I = (en, on, a[d[56]]), _ = []; w < I; ) { var y = l[a.charAt(w++)] << parseInt(p[57], v[58]) | l[a.charAt(w++)] << d[59] | l[a.charAt(w++)] << v[60] | l[a.charAt(w++)]; _.push(y >> parseInt(Vn(f[53], Tn), d[61]), y >> c[51] & parseInt(Xn(X, p[62]), g[51]), y & parseInt(u[64], h[52])) } return _ } function f(n, t, a, i, u) { for (var c = n[o + C]; t < c; ) a[i++] = n[t++] ^ u & parseInt(r[54], e[61]), u = ~(u * parseInt(e[63], r[55])) } for (var v = e[64], l = {}, p = n[29]; p < parseInt(Vn(t[65], r[56]), r[51]); p++) l[v.charAt(p)] = p; function d(n) { for (var a = r[40], o = t[35], i = n[t[59]]; o < i; o++) a = (a << r[57]) - a + n[o]; return a & parseInt(Xn(q, t[66], In), e[61]) } function h(r) { var e = d(r) , a = [c, e]; return f(r, +n[29], a, +t[67], e), g(a) } function g(a) { for (var o = r[40], u = (G, i, a[e[56]]), c = []; o < u; ) { var s = a[o++] << parseInt(b + R, r[51]) | a[o++] << r[51] | a[o++]; c.push(v.charAt(s >> parseInt(e[65], n[53])), v.charAt(s >> parseInt(n[54], t[62]) & parseInt(Xn(e[66], r[58], S), e[61])), v.charAt(s >> r[59] & parseInt(B + i, t[46])), v.charAt(s & parseInt(n[55], r[55]))) } return c.join(Vn(r[26], n[56])) } function m(n) { var t, a, o; t = a = o = r; var i, u, v; i = u = v = e; var l = s(n); if (l[u[27]] != c) return error = i[67], void 0; var p = l[t[37]] , h = []; return f(l, +a[60], h, +i[27], p), d(h) == p ? h : void 0 } a[Vn(r[61])] = g, a[Hn($n, n[57], t[68])] = s, a[k + u] = h, a[O + S] = m }(Qn || (Qn = {}));
运行报错
在浏览器打印o+C是字符串"length"，直接替换
在浏览器打印Vn(r[61])是字符串"100"，直接替换
后面几个都是未定义的，在浏览器找到对应的值替换
a["base64Encode"] = g, a["base64Decode"] = s, a["encode"] = h, a["decode"] = m
直接拿运行之后的结果进行替换
Xn(q, t[66], In)—>"ff"
G—>"w"
Xn(e[66], r[58], S)—>"3f"
B + i—>"3f"
Vn(r[26], n[56])—>""
代码再次执行，值便出来了。
带上值去请求一遍。手机验证码发送成功
hexin-v(js-dom补环境)
在网上看到一堆文章都又说直接用js-dom包补document和window两个环境。
直接把整个js文件复制下来
定义一个全局变量接受v的值,方便后面导出。
运行代码报window未定义
导包
const jsdom = require('jsdom')
const {JSDOM} = jsdom;
const {window} = new JSDOM(``);
运行代码报document未定义
const document = window.document
运行代码报navigator未定义
const navigator = window.navigator
打印值出来了，报错不管他。直接用py调用。也是成功的！
