vue-router动态路由配置

引入路由

import Vue from 'vue'
import Router from 'vue-router'

Vue.use(Router)

动态路由匹配

实现动态路由配置关键是路由嵌套配合router-view(渲染匹配到的路由组件)
例：

export const constantRoutes = [
{
    path: '/', //匹配第一层菜单
    component: Layout,//本条路由映射的组件
    redirect: '/dashboard',
    children: [{  //匹配一级菜单下的二级菜单（匹配的结果会放入<router-view />中）
      path: 'dashboard',
      name: 'Dashboard',
      component: () => import('@/views/dashboard/index'),//二级菜单映射的组件
      meta: { title: 'Dashboard', icon: 'dashboard' }
    }]
  },
  ]


const createRouter = () => new Router({
  // mode: 'history', // require service support
  scrollBehavior: () => ({ y: 0 }),
  routes: constantRoutes
})

const router = createRouter()

// Detail see: https://github.com/vuejs/vue-router/issues/1234#issuecomment-357941465
export function resetRouter() {
  const newRouter = createRouter()
  router.matcher = newRouter.matcher // reset router
}
//暴露路由
export default router
