手把手教你vue实现动态路由

import Vue from 'vue'
import $cookies from 'vue-cookies'
import VueRouter from 'vue-router'
import store from '../store'​
import staticRoute from './static-route.js'​​​
Vue.use(VueRouter)​​
const router = new VueRouter({
	mode: 'history',
	base: process.env.BASE_URL,
	routes: staticRoute //staticRoute为静态路由，不需动态添加
})​
let isToken = true
router.beforeEach(async (to, from, next) => {
	//定义isToken为true和vuex不为空时添加路由
	if (isToken && store.state.routers.routers.length != 0) {
		//从vuex中获取动态路由
		const accessRouteses = await store.state.routers.routers;
		//动态路由循环解析和添加
		accessRouteses.forEach(v => {
			v.children = routerChildren(v.children);
			v.component = routerCom(v.component);
			router.addRoute(v); //添加
		})
		isToken = false //将isToken赋为 false ，否则会一直循环，崩溃
		next({
			...to, // next({ ...to })的目的,是保证路由添加完了再进入页面 (可以理解为重进一次)
			replace: true, // 重进一次, 不保留重复历史
		})​
	} else {
		if (to.name == null) {
			next("/404")
		} else {
			if (to.meta.title) { //判断是否有标题
				document.title = to.meta.title //给相应页面添加标题
			}
			next()
		}​
	}​
})​
function routerCom(path) { //对路由的component解析
	return (resolve) => require([`@/views/${path}`], resolve);
}​
function routerChildren(children) { //对子路由的component解析
	children.forEach(v => {
		v.component = routerCom(v.component);
		if (v.children != undefined) {
			v.children = routerChildren(v.children)
		}
	})
	return children
