做网站有用吗武汉seo顾问
一、数据接口分析
主页地址：天某云
1、抓包
通过抓包可以发现登录接口是account/login
2、判断是否有加密参数
- 请求参数是否加密？
通过“载荷”模块可以发现password、comParam_signature、comParam_seqCode是加密的
- 请求头是否加密？
无 - cookie是否加密？
无 - 响应数据是否加密？
无
二、加密位置定位
1、password
（1）查看启动器
查看启动器发现里面包含异步，所以无法正确找到加密位置
（2）搜索关键字
搜索关键字password:发现有一处位置类似加密位置
在此处打上断点，再次点击登录，返现可以断住，并且a.value是明文，断点的一行是加密的，所以可以断定密码是在此处加密的
2、comParam_signature和comParam_seqCode
直接搜索comParam_signature可以发现只有一处位置有，并且是在请求拦截器中
在此处打断点，然后点击登录，发现可以断住，并且生成方法在这一行上方
三、扣js代码
将上方找到的加密位置代码扣出，缺啥补啥即可

var CryptoJS = require('crypto-js')function desEncrypt(text, n) {var key = CryptoJS.enc.Utf8.parse(n),srcs = CryptoJS.enc.Utf8.parse(text),// CBC 加密模式，Pkcs7 填充方式encrypted = CryptoJS.TripleDES.encrypt(srcs, key, {mode: CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});return encrypted.toString();
