1. 可以看到返回数据是加密的
下边我们用xhr断点来调试分析，附：xhr断点介绍：XHR断点对于大多数初学者来说，可能不知道什么是xhr，但一般都听说过ajax，对的，就是指的在发送ajax(xhr)请求的时候进行阻断的断点，这个是全局断点，可以不提前指定要断哪一个xhr请求，也可以提前指定url，所有的或被选定的xhr请求会在发送之前被阻断。 设置方式为打开sources选项卡，一般在右侧如图画红线的地方。
2. 复制productListVip，粘贴在 XHR.fetch Breakpoints，然后刷新网页
首次相应就像这种内容，好像没什么有用的，不急，我们一步步往下点击，点那个半圆形箭头
3. 一直点击，途中会出现 加密后的数据
然后继续，一步步点击
4. 直到出现 e.encrypt, 感觉好像就是加密的
，我们在 console 里执行以下，会发现显示出明文数据，那就说明就是这个函数里。此时，点击 ↓， 跳到函数里边
5. 会出现，看下return的结果，正是需要的数据
会发现是s函数返回的，它需要6个参数，只有第二个a.a.decode(t)是变化的
6. 此时我们鼠标放到这上边，弹出小框框后，里边有个函数，用鼠标点进去，会出现
7. 以上找见了我们所需要的三个函数，都复制出来，放到pycharm里，直接右键运行新建的js文件，会直接报错，根据报错提示，在网页对应函数的附近找到所需的变量或方法，调整本地js文件，最后完美运行
