Vue-template-admin reports error 405 after packaging dist

See if your Vue routing mode is history or hash
1. First change the publicPath under vue.config.js to './'

2. Change the process.env.NODE_ENV under main.js to ===development

if If it is history mode, it needs to cooperate with the backend.
For example, the backend gives you an address that needs to be accessed: /aaa/ Then you modify it under router.js new Router()

const createRouter = () =>
  new Router({
    
    
      mode: 'history', // require service support
      base:'/aaa/',//这是history的路由模式进行添加base  内容和服务器端保持一致
    scrollBehavior: () => ({
    
     y: 0 }),
    routes: constantRoutes,
  });

const router = createRouter();

Then modify the publicPath in vue.config.js

and then ask if there is a problem with the access address of the backend. Find the responsibility of the backend.
