碎碎念
最近写包，偷懒
想用h5写好，webview加载
然后使用的的事vue3+vite
但是结果打包一直白屏
真是给我整麻了
先说vite那边要做的事，请访问无星的前端之旅（三十）——Vite打包本地预览html

注意文件的放入方式！
要在此处是蓝色文件夹
这样在拆包的时候才会是有文件夹进去
可以通过这个方式查看加载的文件路径无星的前端之旅（十六）——移动端调试技巧/

其中file:///Users/xingwu/Library/Developer/CoreSimulator/Devices/790786D7-9863-4798-8DA8-05D9DAF830A7/data/Containers/Bundle/Application/5D2108CE-F89B-45A6-AB9F-DA3D87F217A6/ComputedMini.app是模拟器中App的路径，右键查看包内容就能看到层级了
如果是非蓝色 文件夹内容引入，所有文件都会在根目录下，所以访问不到白屏！
