I thought vue-router was very simple and easy to understand, and I really used it. I found two problems:
1, the vue-router routing page cannot be added with .html, otherwise there will be no routing page
2, after the code build is deployed on the server, the page cannot be refreshed, and the page will be refreshed directly on 404. This official website seems to need backend configuration.
how to understand these two questions well?. Furthermore, can it be solved through some front-end settings of vue-router?
