并不能搜索到链接明文数据说明数据是动态渲染的。 查看发包有一个getData很可疑返回加密数据 添加XHR断点切换页面触发函数 一步步走找到密文数据 继续跟找到明文数据说明解密函数就在其中 进一步分析可以找到解密处json parse之后就从密文变成了明文可见这就是解密函数

out_data JSON[parse](_0x58b5da(ori_code))
console.log(out_data)下面就是缺什么补什么直接搜索加进去就好了
有一点需要注意的是出现 ReferenceError: window is not defined的情况 这是浏览器环境缺失只要在开头添加一个 var window global;
成功拿到明文数据
