接下来就是微博的js逆向了，这里需要使用到WebStorm
WebStorm下载

需要使用的库
import base64 import requests import re import os import http.cookiejar as cookielib # import pickle import execjs import time import json from PIL import Image from urllib import parse二、分析过程
- 来到到微博主页微博主页
- F12打开chrome开发者模式，输入账号密码，这里账号密码以13888888888，123456为例
点击登录之后 一眼就看到了login这个接口，和右边一堆的参数
多点几次可以看到
su
servertime
nonce
rsakv
sp
只有这几个在变化，我们需要破解的就只有账号和密码
在看一下其他接口，可以发现这样一个包含su的
我们对这个su分析一下，按下Ctrl+shift+f
直接搜索su这个参数，出现了很多个，可以慢慢去找，最终锁定了下面这个
格式化之后，搜索su：
发现su：d
d = sinaSSOEncoder.base64.encode(urlencode(d));
打上断点开始调试，查看一下，这个就是咱们需要的账号加密
而且这个su是通过base64计算得来的
可以直接通过pycharm来对其编写
self.username是传入的账号 代码如下：
su = base64.b64encode(parse.quote(self.username).encode('utf-8')).decode('utf-8')
print('账号已加密：',su)
运行结果：
直接搞定，而且这个接口里面返回的数据有以下几个：
和第一步对比下来，发现post表单里面需要的参数
su
servertime
nonce
rsakv
那就剩下了sp了，这个sp会不会是密码呢？
依旧Ctrl+shift+f 去搜索sp，出现了很多js文件，都格式化之后搜索sp找到了下面这个
e.sp = b;
发现上面有这么一句
b = f.encrypt([me.servertime, me.nonce].join("t") + “n” + b)
打上断掉调试一下
这里看到是sp的加密之后数据
这下准备扣代码了，打开WebStorm，把这段代码复制上去
这里的三个参数，打印出来看一下
me.rsaPubkey
me.servertime
me.nonce
就是通过su那个接口获取的
在继续看这句加密代码
b = f.encrypt([me.servertime, me.nonce].join("t") + "n" + b)
在调试界面把鼠标放在f.encrypt会显示如下图这样
点进去 f bt(a) 看一下
把这段代码复制到WebStorm里面去，把加密那一段注释掉运行一下
提示ReferenceError: sinaSSOEncoder is not defined
sinaSSOEncoder没有定义的话，在开头定义在运行看一下
接着又是 navigator is not defined
这个的话，我可以直接给大家一个navigator代码，直接写在开头用就行了
navigator = {
// WT-JS_DEBUG
appCodeName: "Mozilla",
appMinorVersion: "0",
appName: "Netscape",
appVersion: "5.0 (Windows NT 10.0; WOW64; Trident/7.0; .NET4.0C; .NET4.0E; .NET CLR 2.0.50727; .NET CLR 3.0.30729; .NET CLR 3.5.30729; InfoPath.3; rv:11.0) like Gecko",

systemLanguage: "zh-CN",

userLanguage: "zh-CN",
vendor: "",
vendorSub: "",
webdriver: false
}, window = global, window.navigator = navigator;
在运行一下没有报错
现在就可以改写加密代码块了
我们要打印密码查看，就要先写一个函数声明
function pwd() {
var f = new sinaSSOEncoder.RSAKey;
f.setPublic(me.rsaPubkey, "10001");
b = f.encrypt([me.servertime, me.nonce].join("t") + "n" + b)
console.log(b)
}
直接运行的话实会报错的，里面的四个参数还没传入
me.rsaPubkey
me.servertime
me.nonce
b
b = f.encrypt([me.servertime, me.nonce].join("t") + "n" + b)
括号里面的b是传入的初始密码，改成p
把另外三个去掉me.最后调用pwd()这个函数
调用的时候，在网页哪里把
me.rsaPubkey
me.servertime
me.nonce
这几个参数数据复制下来
传参的方式写入函数，就成为这个样子
function pwd(p,servertime,nonce,Pubkey) {
var f = new sinaSSOEncoder.RSAKey;
f.setPublic(Pubkey, "10001");
b = f.encrypt([servertime, nonce].join("t") + "n" + p)
console.log(b)
}
pwd('123456',
'1632898111',
'7UMHW2',
'EB2A38568661887FA180BDDB5CABD5F21C7BFD59C090CB2D245A87AC253062882729293E5506350508E7F9AA3BB77F4333231490F915F6D63C55FE2F08A49B353F444AD3993CACC02DB784ABBB8E42A9B1BBFFFB38BE18D78E87A0E41B9B8F73A928EE0CCEE1F6739884B9777E4FE9E88A1BBE495927AC4A799B3181D6442443')
运行结果如下
到这里账号密码就就分析完了
pycharm里面的写完又不一样了
需要通过execjs调用js文件才行
import execjs
在这之前，需要通过预登陆获取以下参数
servertime
nonce
rsakv
pubkey
pcid
预登陆url
'https://login.sina.com.cn/sso/prelogin.php'
部分代码如下：
def pre_login(self):
'''预登陆获取数据，这里有反爬，需要加上“Referer”'''
self.params = {
'entry': 'weibo',
'callback': 'sinaSSOController.preloginCallBack',
'su': self.su,
'rsakt': 'mod',
'client': 'ssologin.js(v1.4.19)',
'_': self.time,
}
response = s.get(self.pre_url,params=self.params,headers = self.headers)
# .content是字节码还要编码，但是.text不是所有时候显示都正常，这是就需要用.content进行手动编码。
# 如何修改编码方式：response.content.decode(“utf8”)
# eval() 函数用来执行一个字符串表达式，并返回表达式的值。
res = eval(response.content.decode('utf-8').replace('sinaSSOController.preloginCallBack', ''))
#print(res)
return res
需要注意的是这里有个反爬机制，headers里面需要加上“Referer”
self.headers = {'Referer': 'https://weibo.com/',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.82 Safari/537.36'}
就能取出下面这几个参数了
pcid = res['pcid'] pubkey = res['pubkey'] rsakv = res['rsakv'] nonce = res['nonce'] servertime = res['servertime']
把之前改写的js代码复制到pycharm里面，pwd()需要改写以下，代码如下：
