NavBar.vue:
1.插槽slot可以对应填充内容

<template>
  <div class="nav-bar">
      <div class="left"><slot name="left"></slot></div>
      <div class="center"><slot name="center"></slot></div>
      <div class="right"><slot name="right"></slot></div>
  </div>
</template>
<script>

export default {
  name: 'NavBar',
}
</script>

Recommend.vue:
1.父组件请求数据，然后传给子组件显示
2.子组件根据数据生成相应内容

<template>
  <div class="recommend">
    <div v-for="item in recommends" class="recommend-item">
      <a :href="item.link">
        <img :src="item.image" alt="">
        <div>{{item.title}}</div>
      </a>
    </div>
  </div>
</template>

<script>
  export default {
    name: "RecommendView",
    props: {
      recommends: {
        type: Array,
        default() {
          return []
        }
      }
    }
  }
</script>

Feature.vue:
仅仅是一张图片套了一个a标签

<template>
  <div class="feature">
    <a href="https://act.mogujie.com/zzlx67">
      <img src="~assets/img/home/recommend_bg.jpg" alt="">
    </a>
  </div>
</template>

<script>
  export default {
    name: "FeatureView"
  }
</script>

TabControl.vue:
1.实现局部的商品刷新
2.点击对应类别传递不同商品参数
3.

<template>
  <div class="tab-control">
    <div v-for="(item, index) in titles"
         class="tab-control-item"
         :class="{active: index === currentIndex}"
         @click="itemClick(index)">
      <span>{{item}}</span>
    </div>
  </div>
</template>

<script>
  export default {
    name: "TabControl",
    props: {
      titles: {
        type: Array,
        default() {
          return []
        }
      }
    },
    data() {
      return {
        currentIndex: 0
      }
    },
    methods: {
      itemClick(index) {
        this.currentIndex = index;
        this.$emit('tabClick', index)
      }
    }
  }
</script>

request.js:
1.使用axios插件请求数据

import axios from 'axios'

export function request(config) {
    // 1.创建axios的实例
    const instance = axios.create({
        baseURL: 'http://152.136.185.210:7878/api/m5',
        timeout: 5000
    })

    // 2.axios的拦截器
    // 2.1.请求拦截的作用
    instance.interceptors.request.use(config => {
        return config
    }, err => {
        // console.log(err);
    })

    // 2.2.响应拦截
    instance.interceptors.response.use(res => {
        return res.data
    }, err => {
        console.log(err);
    })

    // 3.发送真正的网络请求
    return instance(config)
}

home.js:
1.home首页的数据请求

import { request } from "./request";

export function getHomeMultidata() {
    return request({
        url: '/home/multidata'
    })
}

export function getHomeGoods(type, page) {
    return request({
        url: '/home/data',
        params: {
            type,
            page
        }
    })
}

利用封装好的swiper、better-scroll、back-top渲染页面功能
