vue router 动态路由清除

重置matcher可达到路由还原效果

在用户退出时调用 resetRouter(router) 即可还原路由

import Vue from 'vue'
import Router from 'vue-router'
import { constantRouterMap } from '...' //导入初始化router

// 传入当前router
export function resetRouter (router) {
  const createRouter = () =>
    new Router({
      mode: 'history'
      routes: constantRouterMap
    })
  // 用初始化的matcher替换当前router的matcher
  router.matcher = createRouter.matcher 
}
