### 导航左-菜单 交互后台 ###

**LeftNav.vue：**

<template>
    	<el-menu  router :default-active="$route.path" default-active="2" class="el-menu-vertical-demo" background-color="#334157" text-color="#fff"
    		active-text-color="#ffd04b" :collapse="collapsed">
    		
    		<div class="logobox">
    			<img class="logoimg" src="../assets/img/logo.png" alt="">
    		</div>
    		<el-submenu v-for="m in menus" :index="'idx'+m.id" :key="'key'+m.id">
    			<template slot="title">
    				<i class="m.icon"></i>
    				<span>{
       {m.text}}</span>
    			</template>
    			<el-menu-item v-for="m2 in m.modules" :index="m2.url" :key="'key'+m2.id">
    				<i class="m2.icon"></i>
    				<span>{
       {m2.text}}</span>
    			</el-menu-item>
    		</el-submenu>
    		
    	</el-menu>
    </template>
    <script>
    	// 从axios中导出数据☞
    	export default {
    		data() {
    			return {
    				// 展开
    				collapsed: false,
    				// 保存了左侧值
    				menus: []
    			}
    		},
    		created() {
    			this.$root.bus.$on('shrink', t => {
    				this.collapsed = t;
    			});
     
    			// 获取到左侧菜单的url
    			let url = this.axios.urls.SYSTEM_MENUS;
    			// 参数传递可以不传
    			this.axios.get(url, {}).then(r => {
    				this.menus = r.data.rows;
    			}).catch(e => {
     
    			});
    		}
     
    	}
    </script>
    <style>
    	.el-menu-vertical-demo:not(.el-menu--collapse) {
    		width: 240px;
    		min-height: 400px;
    	}
     
    	.el-menu-vertical-demo:not(.el-menu--collapse) {
    		border: none;
    		text-align: left;
    	}
     
    	.el-menu-item-group__title {
    		padding: 0px;
    	}
     
    	.el-menu-bg {
    		background-color: #1f2d3d !important;
    	}
     
    	.el-menu {
    		border: none;
    	}
     
    	.logobox {
    		height: 40px;
    		line-height: 40px;
    		color: #9d9d9d;
    		font-size: 20px;
    		text-align: center;
    		padding: 20px 0px;
    	}
     
    	.logoimg {
    		height: 40px;
    	}
    </style>

通过动态路由跳转为当前项内容

router :default-active="$route.path"

#### **定义组件的和路由的关系** ####

**index.js**

import Vue from 'vue'
    import Router from 'vue-router'
    import HelloWorld from '@/components/HelloWorld'
    import AppMain from '@/components/AppMain'
    import LeftNav from '@/components/LeftNav'
    import TopNav from '@/components/TopNav'
    import Login from '@/views/Login'
    import Register from '@/views/Register'
     
    import AddBook from '@/views/book/AddBook'
    import BookList from '@/views/book/BookList'
     
     
    Vue.use(Router)
     
    export default new Router({
    	routes: [{
    			path: '/',
    			name: 'Login',
    			component: Login
    		},
    		{
    			path: '/Register',
    			name: 'Register',
    			component: Register
    		},
    		{
    			path: '/HelloWorld',
    			name: 'HelloWorld',
    			component: HelloWorld
    		},
    		{
    			path: '/AppMain',
    			name: 'AppMain',
    			component: AppMain,
    			children:[{
    				path: '/TopNav',
    				name: 'TopNav',
    				component: TopNav
    			}, {
    				path: '/LeftNav',
    				name: 'LeftNav',
    				component: LeftNav
    			},
    			{
    				path: '/book/AddBook',
    				name: 'AddBook',
    				component: AddBook
    			}, {
    				path: '/book/BookList',
    				name: 'BookList',
    				component: BookList
    			}]
    		}
     
    	]
    })

**action.js**

/**
     * 对后台请求的地址的封装，URL格式如下：
     * 模块名_实体名_操作
     */
    export default {
    	'SERVER': 'http://localhost:8080', //服务器
    	'SYSTEM_USER_DOLOGIN': '/user/userLogin', //登陆
    	'SYSTEM_USER_DOREG': '/user/Register', //注册
    	'SYSTEM_MENUS': '/module/queryRootNode', //左侧菜单树
    	'BOOK_LIST': '/book/queryBookPager', //书籍列表
    	'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用
    		return this.SERVER + this[k];
    	}
    }
