整体思路（模型特殊不考虑，别人封装不具备参考性）

图片上传采用单独的组件，其他三种类型采用一个上传组件（仅仅文件格式不同）
文件上传采用前端直接上传阿里云的方式
图片预览使用elementUI自带的image预览
dwg预览采用 kkfileview 方式，需要后台部署，前端使用 npm install js-base64 ，应该支持所有文件的预览，我们这里仅用作CAD文件的预览
文档类型的直接在浏览器打开预览，如果不支持需要拼接前缀 "https://view.officeapps.live.com/op/view.aspx?src="
图片下载为压缩包
文档类的相同方法下载

上传

在这里插入图片描述
