到这里，基本的代码已经编写完成，webpack打包配置文件基本和官方保持不变，接下来可以尝试启动本地的项目服务，这里简要的使用网易严选首页作为demo示例，结果如下：

第三部分 mockjs和axios配合使用
1、前言
上一节大致介绍了服务端和客户端入口文件代码内容，现在已经可以正常运行你的后端渲染脚手架了，这一节，跟大家分享下如何使用axios做ajax请求，如何使用mockjs做本地假数据，跑通本地基本逻辑，为以后前后端连调做准备。
2、前期准备
需要用npm安装axios，mockjs依赖包,由于mockjs只是代码开发的辅助工具，所以安装的时候我会加--save-dev来区分，具体可以根据自己的需求来定，当然，如果有mock服务平台的话，可以直接走mock平台造假数据，本地直接访问mock平台的接口，例如可以使用阿里的Rap平台管理工具生成。


npm install axios --save
npm install mockjs --save-dev


3、简要介绍axios
其他请求方式，代码示例如下：


axios.request(config);
axios.get(url[,config]);
axios.delete(url[,config]);
axios.head(url[,config]);
axios.post(url[,data[,config]]);
axios.put(url[,data[,config]])
axios.patch(url[,data[,config]])


具体详细可以点击查看axios基本使用介绍
api.js完整代码如下：


import axios from 'axios'
import qs from 'qs'
import Q from 'q'
/**
 * 兼容 不支持promise 的低版本浏览器
 */
require('es6-promise').polyfill();
import C from '../conf'

axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8'
axios.defaults.withCredentials = true

function ajax(url, type, options) {

 return Q.Promise((resolve, reject) => {
 axios({
  method: type,
  url: C.HOST + url,
  params: type === 'get' "htmlcode">

module.exports = {
 HOST: "http://www.xxx.com",
 DEBUGMOCK: true
};


2、在views/index根目录下新建conf.js，定义组件mock的请求路径，并且定义是否开始单个组件使用mock数据还是线上接口数据，代码如下：


const PAGEMOCK = true;
const MODULECONF = {
 index: {
 NAME: '首页',
 MOCK: true,
 API: {
  GET: '/api/home',
 }
 }
};



3、在组件内部定义mockjs来编写mock假数据，代码如下：


import Mock from 'mockjs';
const mData = {
 index: {
 API: {
  GET: {
  "code": 200,
  "data": {
   "pin": 'wangqi',
   "name": '王奇'
  }
  }
 }
 }
}


以上就是基本的流程，如果有更好更灵活的使用方案，希望能够参与沟通并且分享，项目工作流已经在github上分享，并且会继续维护更新， 点击查看详情，希望对大家的学习有所帮助，也希望大家多多支持。
