vue iview实现动态路由和权限验证功能

//util.js
//生成路由
util.initRouter = function (vm) {
 const constRoutes = [];
 const otherRoutes = [];
 // 404路由需要和动态路由一起注入
 const otherRouter = [{
  path: '/*',
  name: 'error-404',
  meta: {
   title: '404-页面不存在'
  },
  component: 'error-page/404'
 }];
 // 模拟异步请求
 util.ajax('menu.json').then(res => {
  var menuData = res.data;
  util.initRouterNode(constRoutes, menuData);
  util.initRouterNode(otherRoutes, otherRouter);
  // 添加主界面路由
  vm.$store.commit('updateAppRouter', constRoutes.filter(item => item.children.length > 0));
  // 添加全局路由
  vm.$store.commit('updateDefaultRouter', otherRoutes);
  // 刷新界面菜单
  vm.$store.commit('updateMenulist', constRoutes.filter(item => item.children.length > 0));
 });
};
//生成路由节点
util.initRouterNode = function (routers, data) {
 for (var item of data) {
  let menu = Object.assign({}, item);
  menu.component = lazyLoading(menu.component);
  if (item.children && item.children.length > 0) {
   menu.children = [];
   util.initRouterNode(menu.children, item.children);
  }
  //添加权限判断
  meta.permission = menu.permission ? menu.permission : null;
  //添加标题
  meta.title = menu.title ? menu.title : null;
  menu.meta = meta;
 }
};

//lazyLoading.js
export default (url) =>()=>import(`@/views/${url}.vue`)
Store缓存实现
//app.js
 // 动态添加主界面路由，需要缓存
updateAppRouter (state, routes) {
 state.routers.push(...routes);
 router.addRoutes(routes);
},
// 动态添加全局路由，不需要缓存
updateDefaultRouter (state, routes) {
 router.addRoutes(routes);
},
// 接受前台数组，刷新菜单
updateMenulist (state, routes) {
 state.menuList = routes;
}

//main.js
 mounted () {
 // 调用方法，动态生成路由
 util.initRouter(this);
 }

//menu.json，模拟异步请求数据

 "path": "/groupOne",
 "icon": "ios-folder",
 "name": "system_index",

  },

 ]
 }
]

//util.js
//生成路由节点
util.initRouterNode = function (routers, data) {
 for (var item of data) {
  ....
  //添加权限判断
  meta.permission = menu.permission ? menu.permission : null;
  ...
 }
};

//hasPermission.js 

const hasPermission = {
 install (Vue, options) {
  Vue.directive('hasPermission', {
   bind (el, binding, vnode) {
    let permissionList = vnode.context.$route.meta.permission;
    if (permissionList && permissionList.length && !permissionList.includes(binding.value)) {
     el.parentNode.removeChild(el);
    }
   }
  });
 }
};
export default hasPermission;
