vue-element-template实战 获取后端路由表动态生成权限

Posted 2020-12-12 windok

主要思路如下：

• 用户登录login获取token
• 拿着token请求用户信息，同时后端返回一个路由表
• 前端解析后动态添加路由表，同时存储到本地localstorage
• 刷新页面或者退出登录或者登录过期等时，会进行相应的判断，重新渲染路由

1、在src/router文件夹下新建_import.js，用于匹配组件，代码如下：

export default file => {
    return map[file] || null
  }
  const map = {
    ‘Layout‘: () => import(‘@/layout‘),
    ‘table‘: () => import(‘@/views/table/index‘),
    ‘tree‘: () => import(‘@/views/tree/index‘),
    ‘form‘: () => import(‘@/views/form/index‘),
    ‘menu1‘: () => import(‘@/views/nested/menu1/index‘),
    ‘menu1-1‘: () => import(‘@/views/nested/menu1/menu1-1‘),
    ‘menu1-2‘: () => import(‘@/views/nested/menu1/menu1-2‘),
    ‘menu1-2-1‘: () => import(‘@/views/nested/menu1/menu1-2/menu1-2-1‘),
    ‘menu1-2-2‘: () => import(‘@/views/nested/menu1/menu1-2/menu1-2-2‘),
    ‘menu1-3‘: () => import(‘@/views/nested/menu1/menu1-3‘),
    ‘menu2‘: () => import(‘@/views/nested/menu2/index‘)
  }
