01 Sekiro服务器部署和第一个示例部署成功，js逆向和加解密

只狼 做穿透部署过程，用于js/android加解密等

第一步： 访问git  ： https://github.com/virjar/sekiro

第二步：访问：demoServer编译和部署 · Sekiro系统文档

第三步：部署服务器   Go HTTP File Server

第四步：访问

​​​快速上手 · Sekiro系统文档

第五步 ：打开浏览器，f12 在source 标签中，找到   snipets，在脚本 中写入

https://sekiro.virjar.com/sekiro-doc/assets/sekiro_web_client.js    复制这里的内容，粘贴到下面的框里。

 下面的示例也一同粘贴到上面框里。

 就是如下代码

第六步：运行浏览器中的脚本

第七步：在浏览器中 访问： http://127.0.0.1:5620/business-demo/invoke?group=ws-group&action=clientTime

得到如下的返回 信息就算成功了。

// http://127.0.0.1:5620/business-demo/invoke?group=ws-group&action=clientTime
