內容管理系統前端實現

一 創建相關文件

1 api

2 頁面組件

3 路由配置

  // 內容管理
  {
    path: '/ad',
    component: Layout,
    redirect: '/ad/list',
    name: 'Ad',
    meta: { title: '內容管理' },
    children: [
      {
        path: 'list',
        name: 'AdList',
        component: () => import('@/views/ad/list'),
        meta: { title: '廣告推薦' }
      },
