成品图

1 运行网易云本地接口

 创建脚手架引入包

vue create music
yarn add axios moment vant vue-router
yarn add babel-plugin-import postcss postcss-pxtorem@5.1.1 -D

关闭eslint

配置vant按需引入

 "plugins": [
      ["import", {
        "libraryName": "vant",
        "libraryDirectory": "es",
        "style": true
      }]
    ]

 配置postcss.config.js

module.exports = {

    plugins: {
        'postcss-pxtorem': {
            rootValue: 37.5,
            propList: ['*']
        }
    }
}

创建页面

vant官网引入组件

Vant 2 - Mobile UI Components built on Vue

配置路由:在layout页面上切换home和search

search和home为layout的子路由

 配置van-tabbar route

 实现头部底布名称统一切换

用van-row来布局页面

发请求显示在页面上

把列表数据封装成组件 SongItem.vue

<template>
  <van-cell :title="name" :label="author+name" @click="$router.push({path:'/comment',query:{id:id}})">
    <!-- 使用 right-icon 插槽来自定义右侧图标 -->
    <template #right-icon>
      <van-icon name="play-circle" @click="playFn" />
    </template>
  </van-cell>
</template>

<script>
export default {
  name: "SongItem",
  props:{
    name:String,
    author:String,
        id:Number
  },
  methods:{
  playFn(){
    this.$router.push({
      path:'/play',
      query:{
        id:this.id
      }
    })
  }
}}
</script>

<style scoped>

</style>

配置search页面

用到了防抖

<template>
  <div>
    <van-search v-model="SearchValue" placeholder="请输入搜索关键词" shape="round"/>
    <div class="search_wrap" v-if="this.resultList.length===0">
      <!-- 标题 -->
      <p class="hot_title">热门搜索</p>
      <!-- 热搜关键词容器 -->
      <div class="hot_name_wrap">
        <!-- 每个搜索关键词 -->
        <span v-for="(obj,index) in SearchList" :key="index" class="hot_item"
              @click="btn(obj.first)"> {{ obj.first }}</span>
      </div>
    </div>
    <!-- 搜索结果 -->
    <div class="hot_search" v-else>
      <!-- 标题 -->
      <p class="hot_title">最佳匹配</p>
      <SongItem  v-for="obj in resultList" :key="obj.id"
                 :name="obj.name"
                 :author="obj.ar[0].name +obj.name"
                 :id="obj.id"/>

      const res = await searchResultAPI({
