python爬虫破解知乎登入加密信息(不使用Selenium模块)

一.分析

仅供学习不要用于商业用途

知乎完成登入的步骤

首先获得cookies(如果不获得后面验证码无法获得)
获得验证码
提交登入相关内容

前两步简单稍微细心寻找规律即可

其中最难的是第三步应该他前端进行了js加密

这里没什么技巧凭感觉因为登入提交的url是https://www.zhihu.com/api/v3/oauth/sign_in

我们进行serch搜索sigin这时候我们会搜索到一条jsmai......js

然后凭身为程序猿的直觉,再获取js代码里搜索encrypt为什么搜这个因为一般程序猿不会瞎命名

然后看着看着我们会发现一条return __g._encrypt(encodeURIComponent(e))

凭感觉这条就可能是,打断点!走起

然后我们随意登入会发现这里的值是

client_id=c3cef7c66a1843f8b3a9e6a1e3160e20&grant_type=password&timestamp=1571641341225&source=com.zhihu.web&signature=628b0f124304c7eb3d7bb12f884666f24fba099c&username=%2B8615757876283&password=11223344&captcha=e7e6&lang=en&utm_source=&ref_source=other_https%3A%2F%2

我的天这个不是我们要的的嘛~~

重复几次失败的登入操作

我们发现client_id参数是不变的,timestamp时间戳猜一猜他尝试一下其实他就是str(int(time.time() * 1000))

唯一难点就是signature

这里还是凭我们程序员的直觉,搜索signature

我们会发现一段js

//这不是告诉我们加密规则了吗
var n = Date.now()
, r = new i.a("SHA-1","TEXT");  //sha1加密方式
return r.setHMACKey("d1b964811afb40118a12068ff74a12f4", "TEXT"),  //盐d1b964811afb40118a12068ff74a12f4
    r.update(e), //提交的参数e,a,n,"com.zhihu.web"
    r.update(a),
    r.update("com.zhihu.web"),
    r.update(String(n)),
    Object.assign({
    clientId: a,  //赤裸裸的告诉我们a是clientId
    grantType: e,   //打断点我们知道他是'password'
    timestamp: n,  //时间戳
    source: "com.zhihu.web",
    signature: r.getHMAC("HEX")    //这里呢可以打断点验证我们想法
}, t)

分析完毕代码走起

二.推理后编写的代码

三.调试时候发生的错误

1.可能会导致错误一(我电脑有环境所有我不清楚)

#这是execjs模块他执行js我们必须给他js能执行的环境,电脑缺环境
#execjs会自动使用当前电脑上的运行时环境（建议用nodejs，与Phantomjs）

2.错误信息二(肯定会报错的哦)

execjs._exceptions.ProgramError: TypeError: __g._encrypt is not a function

我们execjs除了nodejs我们还需要浏览器环境,我们浏览器上还需要document以及window对象所有呢我们要安装环境

移动至项目目录

执行npm install jsdom

代码.py中我们要修改内容

#js_obj = execjs.compile(js_codex)修改成
js_obj = execjs.compile(js_code,cwd='node_modules'),
#也就是导入我们下载完成后的node_modules的文件

然后呢我们在Js_encryption.js

开头添加代码

const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const dom = new JSDOM(`<!DOCTYPE html><p>Hello world</p>`);
window = dom.window;
document = window.document;
XMLHttpRequest = window.XMLHttpRequest;

固定写法别想那么多

3.错误三(解决2之后出来的)

execjs._exceptions.ProgramError: ReferenceError: atob is not defined

百度了一些atob是个window的方法

所有呢我把Js_encryption.js中的atob 全变线成window.atob

运行代码

完美等到了a8H0c79qkLnm2LF0z_pKg9H92Ltxg6O1XGO12rN0cT2tJvS8XLp1DhHKEMVVoBH0sTYhxU9qkLk12LF0z0pMebw1shoYi9omEqYhggHMcvOOsBOB8BF0g6S0gLOfkComBvCmevgqkLP9g9e0zMNmUBHqkLP9nupyEqYhUhe8euofFBF0zLtqoQ90gGoOXqYhyhomogcMUuppkLk0fTFqoTrqcM2pr8tyihYqk4R92LkYJwNm8CSMcrU0g02XNhYqZ9NBFbuBQXSYrR2qGXOqnJLqo7tp2XN8Y_S0Fr9BnBNXNBt9BLfBkvwGUbOYDq3q8Ln8gcgZcUS_iD3ZpvS8Xg9hgqxOcvSMMTYhS0u0k72Xc_FqmMYqr6S0gRo9U9oMzcO1erU0g_xO
