1，创建菜单所以对应的页面

2，创建页面所对应的路由

这里使用了一个插件 coderwhy

npm i coderwhy -g

使用这个命令符可以快速搭建出上述页面

//    coderwhy add3page 文件名 -d 对应目录路径                       
coderwhy add3page dashboard -d src/views/main/analysis/dashboard

3，创建map-menus.ts文件

image.png

import { RouteRecordRaw } from 'vue-router'

export function mapMenusToRoutes(userMenus: any[]): RouteRecordRaw[] {
  const routes: RouteRecordRaw[] = []
  const allRoutes: RouteRecordRaw[] = []

  const routeFiles = require.context('../router/main', true, /\.ts/)
  // console.log('routeFiles', routeFiles.keys())
  //拿到所有页面文件的路径
  routeFiles.keys().forEach((key: any) => {
    //根据路径拿到所有页面文件
    const route = require('../router/main' + key.split('.')[1])
    allRoutes.push(route.default) //default这个属性对应的就是export default 的 default，如果你写成 export xx = {} 那这里就取route.xx
    //也就是说我们把每个文件中导出的对象都push到allRoutes中了
  })

  const _recurseGetRoute = (menus: any[]) => {
    for (const menu of menus) {
      if (menu.type === 2) {
        //根据给的权限菜单 匹配出所需要的菜单的文件
        const route = allRoutes.find((route) => route.path === menu.url)
        if (route) {
          routes.push(route)
        }
      } else {
        _recurseGetRoute(menu.children)
      }
    }
  }
  _recurseGetRoute(userMenus)

  return routes
}

然后在你对应想要获取路由表的地方使用map-menus.ts文件中导出的mapMenusToRoutes函数就可以得到路由表，我的首页叫做mian

  //动态获取路由
      const routes = mapMenusToRoutes(userMenus)
 // 将routes => router.main.children
      routes.forEach((route) => {
        router.addRoute('main', route)
      })

参考：

import { createRouter, createWebHashHistory, RouteRecordRaw } from 'vue-router'
import localCache from '@/utils/cache'

const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    redirect: 'main'
  },
  {
    path: '/login',
    name: 'login',
    component: () =>
      import(/* webpackChunkName: "about" */ '@/views/login/index.vue')
  },
  {
    path: '/main',
    name: 'main',
    component: () => import('@/views/main/index.vue')
  }
]


const router = createRouter({
  history: createWebHashHistory(),
  routes
})

router.beforeEach((to) => {
  if (to.path !== '/login') {
    return localCache.getItem('token') ? true : '/login'
  }
})

export default router

然后菜单组件：

<template>
  <div class="nav-menu">
    <div class="logo">
      <img class="img" src="~@/assets/img/logo.svg" alt="logo" />
      <span v-if="!collapse" class="title">Vue3+TS</span>
    </div>
    <el-menu
      default-active="1"
      class="el-menu-vertical"
      :collapse="collapse"
      background-color="#0c2135"
      text-color="#b7bdc3"
      active-text-color="#0a60bd"
    >
      <template #title>
        <i class="el-icon-delete"></i> <span>Navigator One</span>
      </template>
      <!-- 有子菜单 -->
      <template v-for="menuItem in userMenus" :key="menuItem.id">
        <template v-if="menuItem.type === 1">
          <el-sub-menu :index="menuItem.id + ''">
            <template #title>
              <i v-if="menuItem.icon" :class="menuItem.icon"></i>
              <span>{{ menuItem.name }}</span>
            </template>

            <template v-for="menu in menuItem.children" :key="menu.id">
              <el-menu-item
                :index="menu.id + ''"
                @click="handleMenuItemClick(menu)"
              >
                <i v-if="menu.icon" :class="menu.icon"></i>
                <span>{{ menu.name }}</span>
              </el-menu-item>
            </template>
          </el-sub-menu>
        </template>
        <!-- 无子菜单 -->
        <template v-else-if="menuItem.type === 2">
          <el-menu-item :index="menuItem.id + ''">
            <i v-if="menuItem.icon" :class="menuItem.icon"></i>
            <span> {{ menuItem.name }}</span>
          </el-menu-item>
        </template>
      </template>
    </el-menu>
  </div>
</template>

<script lang="ts">
import { defineComponent, computed } from 'vue'
import { useStore } from '@/store'
import router from '@/router'

export default defineComponent({
  name: 'nav-menu',
  props: {
    collapse: {
      type: Boolean,
      default: false
    }
  },
  setup() {
    const store = useStore()
    const userMenus = computed(() => store.state.login.userMenus)

    const handleMenuItemClick = (menu: any) => {//在点击menu-item的时候push对应路由就行啦~
      router.push(menu.url)
    }
    return {
      userMenus,
      handleMenuItemClick
    }
  }
})
</script>

<style scoped lang="less">
.el-menu {
  width: 250px;

  background-color: #001529;

      color: white;
    }
  }

  .el-menu {
    border-right: none;
  }

  // 目录
  .el-submenu {
    background-color: #001529 !important;
    // 二级菜单 ( 默认背景 )
    .el-menu-item {
      padding-left: 50px !important;
      background-color: #0c2135 !important;

  }

数据返回是这样哒：
