整合vue-router&Vuex
先创建工程
vue create vue-axios
然后选择
勾选
回车，出现是否使用history mode？选择y，代表URL地址里面不会出现#。选择n，代表URL里面带有#。这里我们选择n，看自己需要了。
回车，出现ESLint，直接选第一个即可
回车，勾选默认

回车，选择把配置放在package.json文件里
回车，最后一个选项，问你是否要存储当前的配置为预设配置。你根据需要选择即可。
回车之后开始安装了。
Vuex 用法：修改store.js 和 Home.vue
import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex) export default new Vuex.Store({ state: { // 定义一个状态，并赋值 name: '待改名' }, mutations: { // 接受 state 作为第一个参数，你可以传入额外的参数，即 mutation 的 载荷（payload）。在大多数情况下，载荷应该是一个对象，这样可以包含多个字段并且记录的 mutation 会更易读 setName(state, payload) { state.name = payload.name; } }, actions: {} })
Home.vue
<template> <div class="home"> <h1>{{globalName}}</h1> <div> <button @click="changeStatus">更改状态</button> </div> <img alt="Vue logo" src="../assets/logo.png"> <HelloWorld msg="Welcome to Your Vue.js App"/> </div> </template> <script> // @ is an alias to /src import HelloWorld from '@/components/HelloWorld.vue' export default { name: 'home', components: { HelloWorld }, computed: { // 从 store 实例中读取状态最简单的方法就是在计算属性中返回某个状态 globalName: function () { return this.$store.state.name; } }, methods:{ // 更改 Vuex 的 store 中的状态的唯一方法是提交 mutation;你不能直接调用一个 mutation handler,要唤醒一个 mutation handler，你需要以相应的 type 调用 store.commit 方法 changeStatus: function () { this.$store.commit('setName',{ name: '阿猫阿狗' }); } } } </script>

整合Axios
你可以进入工程目录执行以下命令，或者用WebStorm打开后，在Terminal里执行以下命令来安装Axios。
$ npm install axios
测试运行
先看一下工程目录结构
然后修改文件 main.js
加入
import Axios from 'axios' // 引入Axios Vue.prototype.$axios = Axios; // 全局变量
再修改 About.vue，内容如下（由于懒得写接口测试了，直接调用的墨迹天气，然后由于跨域问题，无法访问，所以我把catch块中写了死数据）
<template> <div class="about"> <table style="width: 300px;margin: 0 auto;"> <tbody> <tr v-for="w in dataList.hour24" :key="w.Fpredict_hour"> <td>{{w.Fpredict_date}}</td> <td>{{w.Fpredict_hour}}点</td> <td>{{w.Fcondition}}</td> </tr> <tr> <td colspan="3">一共{{totalCount}}条数据</td> </tr> </tbody> </table> </div> </template> <script> export default { name: 'about', data: ()=> ({ dataList: {}, totalCount: 0 }), mounted: function () { let me = this; me.getDataForTable() .then(data => { me.dataList = data.data me.totalCount = data.count }) }, methods: { getDataForTable () { let me = this; return new Promise((resolve, reject) => { // 额外的参数，比如headers // let options = { // headers: { // 'token': '00000' // } // } // 参数 let params = {}; me.$axios.post('http://tianqi.moji.com/index/getHour24',params/*,options*/) // 请求成功后 .then(function (response) { let data = response.data; let count = data.hour24.length resolve({ data, count }) }) // 请求失败处理 .catch(function (error) { console.log(error); let data = { "hour24": [ { "Fpredict_date": "2019-06-18", "Ficon_id": 2, "Fcondition_id": 13, "Ftemp": 28, "Fwspd": 16.92, "Fwind_dir_id": 8,
