现有系统是lnmp环境，用到 HTML5、CI
希望实现商品导入功能，以上传文件夹的形式，如果网络断掉了，还可以继续上传商品。怎么实现比较稳妥呢？
/goods.csv 所有商品信息
/category.csv 分类

WEB application does not seem to have a folder upload function. The problem itself does not exist.
If it is uploaded in the form of a compressed package, then the compressed package has not been uploaded completely and it should not be unpacked and imported.
