mock.js的使用以及主界面搭建

mock.js模拟响应ajax请求

安装mock.js依赖

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

右击打spa项目所在目录shift+右击选择命令窗口

成功：

如果失败就删掉spa项目重新下载

配置开发环境及生产环境
为了只在开发环境使用mock，而打包到生产环境时自动不使用mock，我们可以在env中做一个配置
决定使不使用

dev.env

'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')

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

prod.env

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

点击：资料的分享
放入要用的图片

导入main.js引用（此用的是工具包，资料有分享）

//开发环境下才会引入mockjs
process.env.MOCK && require('@/mock')
import 'element-ui/lib/theme-chalk/index.css' //在css上面引用
import App from './App'

一定放在APP之前

main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
process.env.MOCK && require('@/mock')
import 'element-ui/lib/theme-chalk/index.css'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'
import axios from '@/api/http'   
// import axios from 'axios'     
import VueAxios from 'vue-axios'

Vue.use(ElementUI)
Vue.use(VueAxios,axios)
Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

注1：import是ES6标准中的模块化解决方案，require是node中遵循CommonJS规范的模块化解决方案
后者支持动态引入，也就是require(${path}/xx.js)

mock的使用

在src目录下创建mock目录，定义mock主文件index.js，并在该文件中定义拦截路由配置，
      /src/mock/index.js
      
      导入公共模块及mockjs全局设置
      import Mock from 'mockjs' //引入mockjs，npm已安装
      import action from '@/api/action' //引入封装的请求地址
 
      //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
      })

注1：index.js文件的作用很显然,就是将分散的xxx-mock文件集合起来.后面再添加新的mock文件,都需要在这里引入

去App.vue运行测试结果：

后台主界面搭建

结构

导入组件（上面资料有分享）

路由配置src/router/index.js

import AppMain from '@/components/AppMain'

新增映射

{
			path: '/AppMain',
			name: 'AppMain',
			component: AppMain
		}

修改Login.vue的登录成功时跳主界面

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

AppMain.vue为主界面，重载着LeftNav.vue和TopNav.vue组件

AppMain.vue

界面不报错，箭头样式出现向左边，功能后面才实现

点击退出可退出返回登录界面：

Vue总线的概念及使用

目的：
点击TopNav中的图片按钮，改变左侧LeftNav的样式，也就是改变该组件中的属性值，并且改变AppMain组件中的属性值
分析：
TopNav/LeftNav/AppMain这三个组件的关系
可以看出TopNav与LeftNav是兄弟组件，他们要传值，如果通过组件通信的方式去做，是相当麻烦的，所以就出现Vue总线的概念

main.js

	  return {
		  Bus:new Vue({
			  
		  })
	  }
