## vue-cli中使用ajax请求 ##

### 创建好vue-cli项目，命令行在该路径下运行以下命令 ###

npm install --save axios

### 在main.js中添加标记行import axios from ‘axios’ ###

import Vue from 'vue'
    import App from './App'
    import router from './router'
    import axios from 'axios'
    
    Vue.config.productionTip = false
    
    /* eslint-disable no-new */
    new Vue({
      el: '#app',
      router,
      components: { App },
      template: '<App/>'
    })

### router/index.js作用解释 ###

import Vue from 'vue'
    //导入路由
    import Router from 'vue-router'
    //导入页面组件
    import Login from '@/components/Login'
    import Manage from '@/components/Manage'
    //使用路由
    Vue.use(Router)
    
    export default new Router({
    //不显示#符号的url
      mode:'history',
      routes: [
      //登录页面对应的url，如：localhost:8080/login
        {
          path: '/login',
          name: 'Login',
          component: Login
        },
        //首页页面对应的url，如：localhost:8080
      		{
      		  path: '/',
      		  name: 'Manage',
      		  component: Manage,
      		}
      ]
    })

### assets文件夹用于放图片文件 ###

### config/index.js ###

'use strict'
    // Template version: 1.3.1
    // see http://vuejs-templates.github.io/webpack for documentation.
    
    const path = require('path')
    
    module.exports = {
      dev: {
    
        // Paths
        assetsSubDirectory: 'static',
        assetsPublicPath: '/',
        //设置同源访问，不然不能够访问后台接口
        proxyTable: {
    		'/api': {  //使用"/api"来代替"http://f.apiplus.c" 
    			target: 'http://10.18.45.66:8000', //源地址 
    			changeOrigin: true, //改变源 
    			pathRewrite: { 
    			  '^/api': 'http://10.18.45.66:8000' //路径重写 
    			  } 
    		  } 
    	},
    
        // Various Dev Server settings
        //设置访问主机
        host: '10.18.45.66', // can be overwritten by process.env.HOST
        port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined

    }

### components用于放页面组件 ###

//html页面
