注意！！！！某XX网站逆向实例仅作为学习案例，禁止其他个人以及团体做谋利用途！！！

第一步：抓包工具第一次请求页面，得到响应。本次我使用的fiddle进行抓包，可以直接请求得到响应，响应内容一样。发现响应内容是不可直接用的内容，但是有明确的cookie关键词，同时响应里的headers得到了set-cookie的值

第二步：抓包工具第二次请求。将第一次请求拿到的cookie放在请求headers 里再次请求，同时将步骤一里响应内容进行解析。也就是图里的cookie的两个值。（看不懂的等下看代码吧）

第三步：抓包工具第三次请求。可以看到得到了正确的页面响应内容，同时cookie值也和前两次的不一样

第四步：这里将是一段描述梳理一下每次请求的作用

第一次请求：响应内容为混淆后的cookie值，该cookie作用为第二次请求的必要条件；

第二次请求：响应内容为混淆后的cookie值，该cookie作用为最终请求的必要条件；

最终请求：响应内容为我们看到的页面内容。

第五步：解析第一次请求的响应内容。通过正则表达式将cookie内容取出，利用eval() 函数直接在本地或者浏览器的console 就可以直接解析。

第步六：注意啦！！！！这步开始容易猪猪迷惑了。分析并解析第二次请求的响应内容。根据观察响应内容为ob 混淆加密建议找个工具或者用什么方法进行解密。(可以参考JS逆向 | ob混淆一键还原工具_js反混淆还原工具_丁仔.的博客-CSDN博客和GitHub - DingZaiHub/ob-decrypt: ob混淆还原工具，欢迎star！亲测用着还可以).这里可以使用hook方式进行解析，在浏览器中按照图所示进行操作

第七步：将一大坨响应内容进行ob混淆解密操作，没有工具这部可以忽略。为方便分析，我将第二次响应内容存在本地.html 文件。将ob混淆代码另存在.js 文件，使用工具进行解密，成功后把解密后的js代码替换本地.html中的js 内容。

第八步：在 .html 中补充 debugger 关键词，同时将.html 文件复制到第六步新建的文件夹中 。此时浏览器上会自动识别，按图勾选即可。由于我们分析解析目的是为了找cookie，因此和cookie有关的就是document ,所以在替换文件里搜索 document ，找到后打上断点。

第九步：清除浏览器上的cookie重新请求，注意清除cookie后会首先断在debugger处，接着按下F8(蓝色的按钮，执行下一个断点)就可以。执行到document['cookie'] 处可以看到已经被赋值，直接看一下被哪些所赋值，可以看到标红处就是我们需要的cooke

第十一步：找cookie出处。

第十二步：cookie生成包含两个参数，均是从同一个对象中获取的，将该对象进行全局所有找到其出处

最后代码展示

# 注意啦！！！！！！！由于go方法传的参数不是固定值且 “ha”加密方式也不一样。因此代码里才有显示三种方式，目前我只遇到三种。后面有的话在补充。
