路由配置文件

import Vue from 'vue'
import Router from 'vue-router'
import home from '@/components/home'
import about from '@/components/about'


Vue.use(Router)

export default () => {
  return new Router({
    mode: 'history', //一定要是history模式
    routes: [
      {
        path: '/',
        name: 'home',
        component: home
      },
      {
        path: '/about',
        name: 'about',
        component: about
      }
    ]
  })
} 

Vuex配置文件

import Vue from 'vue';
import Vuex from 'vuex';
import axios from 'axios';
Vue.use(Vuex);

export default function createStore(){
    let store = new Vuex.Store({
        state:{
            homeInfo:''
        },
        actions:{
            getHomeInfo({commit}){
                return new Promise((resolve,reject)=>{
                    axios.get("api地址").then(res=>{
                        commit('setHomeInfo',res.data);
                        resolve();
                    }).catch(reject);
                })
            }

            }
        }
    })
    return store;
}

请求数据的页面

package.json的scripts配置信息

 "scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
    "start": "npm run dev",
    "build": "node build/build.js",
    "server": "webpack --config build/webpack.server.config.js",
    "client": "webpack --config build/webpack.client.config.js"

服务器文件

const Vue = require('vue');
const Koa = require('koa');
const server = new Koa();
const path = require("path");
const koaStatic = require('koa-static');
const router = require('koa-router')();


//创建服务端渲染器
const renderer = require("vue-server-renderer").createRenderer();
const createApp = require('./dist/bundle.server.js')['default'];

//设置静态资源目录
server.use(koaStatic(path.resolve(__dirname,"./dist")))

const  clientBundleFileUrl = "/bundle.client.js";


router.get('/text',async ctx=>{
    ctx.body={
        code:1,
        message:"我是服务器返回的测试内容！"
    }
})

router.get('*',async ctx=>{
    const context = { url:ctx.request.url };
    try{
