vue3 bug

• 新建菜单的路由地址不能重复，否则上一个会404

vue2bug

• npm run build:prod 打线上包之后报错
  
  
• 原因：webpack 版本问题，webpack4 不支持变量方式的动态 import ，新版本的使用 require() 来解决此问题
• 修改
  
src/store/modules/permission.js


// src/store/modules/permission.js
export const loadView = (view) => {
  if (process.env.NODE_ENV === "development") {
    return (resolve) => require([`@/views/${view}`], resolve);
  } else {
    // 使用 import 实现生产环境的路由懒加载
    // return () => import(`@/views/${view}`)
    return (resolve) => require([`@/views/${view}`], resolve);
  }
};

bug：个人中心 — 上传图像报错

• 微服务版本：后台提示没有接收到文件扩展名，可以后台手动写死一个，或者前端加一个新字段
• 前后端分离版：图像上传成功但无法显示，因为后台返回的半截路径，需要拼接一个imgUrl

修改域名 vue.config.js 中代理域名

	proxy: {
      // detail: https://cli.vuejs.org/config/#devserver-proxy
      [process.env.VUE_APP_BASE_API]: {
        target: `http://192.168.2.81:8080`,
        changeOrigin: true,
        pathRewrite: {
          ['^' + process.env.VUE_APP_BASE_API]: ''
        }
      }
    },

菜单点击跳转全屏页面

• 1、新建菜单screen，然后再路由文件再定义一遍
• 2、新建菜单，直接跳转外部链接，加上线上测试地址，会新打开一个窗口

// 公共路由
export const constantRoutes = [
  {
    path: "/screen",
    component: () => import("@/views/screen/index"),
    hidden: true,
  },
]

新增自定义样式

• 在index.scss中引入

@import './ququ.scss';

• ququ.scss
