install router ：是否安装路由，选择安装就后面我安装步骤就不用执行
Use ESLint to lint your code? (Y/n)：问你是否使用eslint限制语法，新手建议否
Set up unit tests (Y/n):单元测试，新手选否
Setup e2e tests with Nightwatch? (Y/n)：使用Nightwatch设置端到端测试?，选否
Should we run `npm install` for you after the project has been created?：用什么方式运行项目：选npm

vue ui

npm install vue-router

npm install axios

// 导入包
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import ElementUI from 'element-ui'
import axios from 'axios'

Vue.config.productionTip = false
// elementui
Vue.use(ElementUI)
Vue.prototype.$axios = axios

new Vue({
  el: '#app',
  // 路由
  router,
  render: h => h(App),
}).$mount('#app')

import Vue from 'vue'
import Router from 'vue-router'
import Login from '@/components/Login'
import maintry from '@/views/maintry'
import addScore from '@/views/addScore'
import deleteScore from '@/views/deleteScore'
import showScore from '@/views/showScore'
import updateScore from '@/views/updateScore'

// 挂载vue-router
// 将组件添加到router
Vue.use(Router)
export default new Router({
    routes: [
        {
            path: '/',
            redirect: '/login'
        },
        {
            path: '/login',
            name: 'Login',
            component: Login
        },
        {
            path: '/maintry',
            name: 'maintry',
            component: maintry
        },
        {
            path: '/addScore',
            name: 'addScore',
            component: addScore
        },
        {
            path: '/deleteScore',
            name: 'deleteScore',
            component: deleteScore
        },
        {
            path: '/showScore',
            name: 'showScore',
            component: showScore
        },
        {
            path: '/updateScore',
            name: 'updateScore',
            component: updateScore
        }
    ]
})

ps: 需要注意的是，配置好了路由，你还需要在App.vue里进行声明，需要在App.vue
加入<router-view/>代码

<template>
  <div id="app">
      <router-view/>
  </div>
</template>

<script>

export default {
  name: &#39;app&#39;
}
</script>

<style>
#app {

  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
    height: 100%;
}
</style>

import axios from 'axios'

// 创建axios实例
// eslint-disable-next-line no-unused-vars
const service = axios.create({
    // baseURL: '/', // api的base_Url
    // 后端的请求路径
    baseURL: 'http://localhost:8081/student', // api的base_Url
    timeout: 50000 // 请求超时时间
})

// 请求拦截器
axios.interceptors.request.use(
    function (config) {
        // 在发送请求之前做些什么
        return config
    },
    function (error) {
        // 对请求错误做些什么
        return Promise.reject(error)
    }
)

// 响应拦截器
axios.interceptors.response.use(
    function (config) {
        // 对响应数据做点什么
        return config
    },
    function (error) {
        // 对响应错误做点什么
        return Promise.reject(error)
    }
)

export default service

// 导入axios配置
import service from '../utils/request'

// 登录
export function loginTosystem(username, password) {
    return service.get('/login/loginTosystem', {
        headers: { 'Content-Type': 'application/json' },
        params: {
            username: username,
            password: password
        }
    })
}

// 导入axios配置
import service from '../utils/request'

// 注册账号
export function registerAccount (obj) {
    return service.post('/register/registerAccount', JSON.stringify(obj), {
        headers: { 'Content-Type': 'application/json' }
    })
}
