某航空网站promise异步定位js逆向解析

本次目标地址如下，使用base64解码获得

打开网址，抓包分析后，发现响应结果在该请求中：
在这里插入图片描述
我们跟栈进去查找，从右边的堆栈调用过程中发现，这是典型的axios请求

针对这种请求，一般加密都是在请求拦截器中，通常定位到加密的有两种方式，找到响应拦截器，因为响应拦截器一般和请求拦截器在一块地方，第二种就是找到请求拦截器，这里就简单讲第一种方式
在这里插入图片描述
如上图，找到处理响应结果的地方，通过跳出当前函数这一功能，点击两次后，就找响应拦截器的位置了
并且上方这块就是请求拦截器了，也能找到加密的位置，加密的参数来自于A函数

跳转到A函数之后, 发现就是用一些随机字符串和时间戳，以及一些固定加密参数去使用标准加密算法进行加密，因为加密代码没有任何混淆，所以，破解也很容易
在这里插入图片描述
这里可以直接把A函数扣下来，把一些环境补齐，如下
