• Vue(七)整合vue-router&Vuex&Axios


    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.jsHome.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=" 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 count = data.hour24.length
                                resolve({

                            // 请求失败处理
