之前看到网上有些动态设置路由的,但是跟目前的项目不是很匹配,就自己动手实现了一种。主要思路就是:

1.配置路由的时候绑定好id,可后端开发完成后,与后端同步id就行,这id唯一不变,根据此id可找到路由地址及icon。

const routerArr = [
 {
 path: '',
 name: '',
 component: () => import( /* webpackChunkName: "strategiesMaintain" */ '@/components/Layout/Index'),
 meta: {
 requireAuth: true,
 id: 1,
 icon: 'iconzhanghuguanli',
 title: '路由1'
 },
 children: [{ 
 path: '/verificationLog',
 name: 'VerificationLog',
 component: () => import( /* webpackChunkName: "verificationLog" */ '@/views/auditManage/verificationLog'),
 meta: {
 requireAuth: true,
 id: 101,
 icon: 'icon-disanfangyanzhengrizhi',
 title: '路由11'
 }
 }, {
 path: '/systemLog',
 name: 'SystemLog',
 component: () => import( /* webpackChunkName: "systemLog" */ '@/views/auditManage/systemLog'),
 meta: {
 requireAuth: true,
 id: 102,
 icon: 'icon-xitongcaozuorizhi',
 title: '路由12'
 }
 }]
 }
];

export default routerArr;

2.设置本地路由与后端传来的路由的联系,主要是根据id绑定路由地址及iconClass

import routerModules from "@/router/modules";
import {http} from '@/utils/http'
import store from '@/store';
import { Message } from 'element-ui'

const formateResData = (val) =>{ // 格式化路由数据
 const obj = {};
 const fn = (arr)=>{
  for(let i = 0,item;item = arr[i++];){
  obj[item['meta']['id']] = {
   path: item['path'],
   iconClass: item['meta']['icon']
  };
  if(item.children && item.children.length > 0){
   fn(item.children);
  }
  }
 }
 fn(val);
 return obj;
};

const MAPOBJ = formateResData(routerModules);
const dealWithData = (navData) => { // 处理菜单数据
 let firstLink = "";
 const navIdArr = [];
 const fn = (arr) => {
  for (let i = 0,item;item = arr[i++];) {
  item['iconClass'] = MAPOBJ[item.id].iconClass;
  item['linkAction'] = MAPOBJ[item.id].path;
  navIdArr.push(item.id);
  if (!firstLink && !item.subMenu) { // 设置默认跳转
   firstLink = item['linkAction'];
  }
  if (item.subMenu && item.subMenu.length > 0) {
   fn(item.subMenu);
  }
  }
 }
 fn(navData);
 return {navData,navIdArr,firstLink};
};

let navIds = [];

const getNav = async (to={},from={},next=()=>{})=>{ // 获取导航数据
 const {code,data} = await http("/menu/list", {}, "GET"); // 获取菜单数据
 // const data = require("@/mock/api/menuData"); // 使用mock数据
 const {navData,navIdArr,firstLink} = dealWithData(data);
 store.commit('setNavData', navData);
 navIds = navIdArr;
 if(to.fullPath == '/index'){ // 从登录过来 或者是回首页
 next(firstLink);
 }else { // 刷新
 if(navIds.indexOf(to.meta.id) == -1){ // 后端没有返回该菜单
  Message.error('菜单不存在或者没有权限');
  return;
 }
 next();
 }
}

export const setGuard = (to={},from={},next=()=>{}) =>{ // 设置权限
 if(navIds.length === 0){ // 还没有获取菜单数据
 getNav(to,from,next);
 }else { // 获取到菜单数据
 if(navIds.indexOf(to.meta.id) == -1){ // 后端没有返回该菜单
  Message.error('菜单不存在或者没有权限');
  return;
 }
 next();
 }
}

3.在mainjs中引入配置

router.beforeEach((to, from, next) => {
 let token = wlhStorage.get("authorization");
 if (to.path == "/login") {
 storage.clear();// 清空缓存
 next();
 } else {
 if (to.meta.requireAuth && token) { // 登陆
  setGuard(to,from,next);
 } else { // 没有登录
  next("/login");
 }
 }
})

总结
