路由配置

import { createRouter, createWebHistory, RouteRecordRaw } from 'vue-router'
import index from '@/index.vue'
import websiteUsage from '@/components/contentList/usage/websiteUsage.vue'
import galleryUsage from '@/components/contentList/usage/galleryUsage.vue'

const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    name: 'home',
    component: index,
    meta:{
      title:'首页'
    }
  },
  {
    path: '/usageProcess',
    name: 'galleryUsage',
    component: index,
    meta:{
      title:'使用流程'
    },
    children:[
      {
        path: 'websiteUsage',
    name: 'websiteUsage',
    component: websiteUsage,
    meta:{
      title:'网站使用流程'
    }
  },
  {
    path: 'galleryUsage',
name: 'galleryUsage',
component: galleryUsage,
meta:{
  title:'创建图库流程'
}

    ]

    path: '/gallery',
    name: 'gallery',
    component: index,
    meta:{
      title:'创建图库'
    }

const router = createRouter({
  history: createWebHistory(process.env.BASE_URL),
  routes
})
export { routes }
export default router
