一、mock的使用

1、安装mockjs依赖

  npm install mockjs -D              #只在开发环境使用

 下载完可以在 package.json里看到

2、引入到main.js中使用

dev.env ：

module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
   MOCK: 'true'
      })

prod.env：

module.exports = {
NODE_ENV: '"production"',
MOCK: 'false'
      }

3、添加默认接口数据

我们需要准备好mock文件夹

 然后造数据

 4、绑定接口数据

mock/inde.js:

import Mock from 'mockjs' //引入mockjs，npm已安装
import action from '@/api/action' //引入请求地址
 
//全局设置：设置所有ajax请求的超时时间，模拟网络传输耗时
Mock.setup({
	// timeout: 400  //延时400s请求到数据
	timeout: 200 - 400 //延时200-400s请求到数据
})
 
//引登陆的测试数据，并添加至mockjs
import loginInfo from '@/mock/json/login-mock.js'
let s1 = action.getFullPath('SYSTEM_USER_DOLOGIN')
Mock.mock(s1, "post", loginInfo)
// Mock.mock(s1, /post|get/i, loginInfo)

二、主界面搭建&左侧树收缩功能 

主界面布局：

1、导入图片
2、导入AppMain.vue / LeftMav.vue / TopNav.vue
3、AppMain.vue中注册使用组件
4、router/index.js中添加路由和组件的映射
5、修改添加组件中需要用到的变

AppMain.vue：

<template>
	<el-container class="main-container">
		<el-aside v-bind:class="asideClass">
			<LeftNav></LeftNav>
		</el-aside>
		<el-container>
			<el-header class="main-header">
				<TopNav></TopNav>
			</el-header>
			<el-main class="main-center">Main</el-main>
		</el-container>
	</el-container>
</template>
 
<script>
	// 导入组件
	import TopNav from '@/components/TopNav.vue'
	import LeftNav from '@/components/LeftNav.vue'
 
	// 导出模块
	export default {
		components:{
      TopNav,LeftNav
    },
    data(){
      return {
        asideClass:'main-aside'
      }
    },
    created() {
      //从总线上取出this.collapsed变量
      this.$root.Bus.$on("collapsed-side",v => {
        this.asideClass = v ? 'main-aside-collapsed' : 'main-aside';
      })
    }
	};
</script>
<style scoped>
	.main-container {
		height: 100%;
		width: 100%;
		box-sizing: border-box;
	}
 
	.main-aside-collapsed {
		/* 在CSS中，通过对某一样式声明! important ，可以更改默认的CSS样式优先级规则，使该条样式属性声明具有最高优先级 */
		width: 64px !important;
		height: 100%;
		background-color: #334157;
		margin: 0px;
	}
 
	.main-aside {
		width: 240px !important;
		height: 100%;
		background-color: #334157;
		margin: 0px;

	.main-header,
	.main-center {

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";

Vue.use(Router)
 
export default new Router({
  routes: [
    {
      path: '/',
      name: 'Login',
      component: Login
    },
    {
      path: '/Login',

三、退出功能 

exit(){
        this.$router.push({path:'/Login'})
      }
