特性：

1、支持任意深度的chm文件解析

2、解析后内容结构转换为tree数据呈现

3、点击树节点可以在html实时查看数据 

4、不依赖任何浏览器端插件，兼容性较好

nodejs端核心代码

module.exports = global.SG.router;

let webRootPath = 'http://127.0.0.1:9999/chm/';//测试环境chm文件根目录

//上传单个文件（all方法支持POST、GET、PUT、PATCH、DELETE传参方式）
let uploadFileName = '';//获取上传后的文件名
router.all(
    "/chm/upload",//接口路径
    $g.dir.upload(
        "./upload",//存储临时上传文件的路径
