一、项目技术
基于 Vue + Vant UI组件库 实现网易云音乐
Vant UI (有赞团队打造的移动端Vue组件库)地址:https://vant-contrib.gitee.io/vant/#/zh-CN
共项目共实现四个功能:主页Home、搜索页Search、评论页Comment、播放页Play
网易云手机端地址:https://y.music.163.com/m
二、准备工作
1、初始化Vue项目
① 安装Vue脚手架
npm i @vue/cli -g
② 切换到要创建项目的目录,然后创建music项目
vue create music
③ 启动项目
npm run serve
2、配置Vant UI组件库
① 下载vant ui库
注意项:Vant组件库要下载配合Vue2版本的使用
npm i vant@latest-v2
② 配置按需引入样式
在基于 vue-cli 的项目中使用 Vant 时,可以使用 unplugin-vue-components 插件
,它可以自动引入组件,并按需引入组件的样式。
安装插件
npm i unplugin-vue-components -D
配置插件:在 vue.config.js 文件中配置插件
const { VantResolver } = require('unplugin-vue-components/resolvers');const ComponentsPlugin = require('unplugin-vue-components/webpack');module.exports = { configureWebpack: { plugins: [ ComponentsPlugin({ resolvers: [VantResolver()], }), ], },};
优点:减少代码体积
缺点:使用起来会变得繁琐一些
3、下载并使用vue-router库
① 下载vuex库(vue2中必须使用vue-router3版本)
npm i vue-router@3
② 引入
import VueRouter from "vue-router"
③ 使用VueRouter
Vue.use(VueRouter)
④ 使用VueRouter之后,在创建vm的时候就可以传入一个router配置项
new Vue({//使用VueRouter之后,创建vm的时候可以传入一个router配置项 router, render:h=>h(App),}).$mount("#app")
4、接口API
项目地址:https://neteasecloudmusicapi.js.org/#/
文档地址:https://binaryify.github.io/NeteaseCloudMusicApi/#/
① 安装项目
// 从github上克隆项目到本地git clone git@github.com:Binaryify/NeteaseCloudMusicApi.git// 安装依赖包npm install
② 运行项目
node app.js
③ 本地地址
http://localhost:3000
5、postcss插件
webpack的一个插件,将要px转化为rex插件
中文官网:https://www.postcss.com.cn/
① 安装postcss
npm install postcss
② 安装postcss-pxtorem(最新版本6.0与Vant不兼容,因此安装5.1.1版本)
postcss-pxtorem是postcss插件,把px转换成rem
npm install postcss-pxtorem@5.1.1 --s-d
③ 根目录下创建postcss.config.js文件
module.exports = { plugins: { 'postcss-pxtorem': { rootValue: 37.5, // 已设计稿宽度375px为例 vant用的是375的设计稿 propList: ['*'], }, },};
三、分析页面实现功能
分析:
① 根据项目页面构成,我们要创建4个vue组件,分别是views/Home、views/Search、views/Comment、views/Play
② 页面之间通过路由跳转,因此要创建文件夹 router/index.js
③ 页面所需要的数据是通过发送网络请求获取的,因此要创建untils/request.js文件,api/index.js作为统一出口
④ 首页和搜索页的顶部和底部一样,可以将这部分提取为一个组件,因此要创建views/layout.vue
⑤ 首页最新新闻和搜索页最佳匹配样式结构一样,因此也可以提取出来,创建components/songItem.vue组件
1、路由页面准备
layout属于一级路由,home和search属于二级路由;comment、play属于一级路由
src/router/index.js文件代码
import Vue from "vue";import VueRouter from "vue-router";import Layout from "@/views/Layout";import Home from "@/views/Home";import Search from "@/views/Search";import Play from "@/views/Play";import Comment from "@/views/Comment"Vue.use(VueRouter);export default new VueRouter({ routes:[ { path:"/", redirect:'/layout', }, { path:"/layout", redirect:'/layout/home', component:Layout, children:[ { name:'home', path:'home', component:Home, meta:{ title:'首页' } },{ name:'search', path:'search', component:Search, meta:{ title:'搜索' } } ] }, { name:'play', path:'/play', component:Play, }, { name:'comment', path:'/comment', component:Comment } ]})
2、封装axios网路请求
新建untils/request.js
import axios from "axios";// axios.create()创建一个axios对象const request = axios.create({ //基础路径,发请求的时候,路径当中会出现api,不用你手写baseURL:'http://localhost:3000',//请求时间超过5秒timeout:5000});export default request
3、公共组件
components/songItem.vue组件
<template> <van-cell :id="id" :title="name" :label="autor" @click="getComment(id)"> <template #right-icon> <van-icon name="play-circle-o" class="search-icon" @touchstart ="playFn(id)"/> </template> </van-cell></template><script>export default { name:'SongItem', props:{name:String,autor:String,id:Number}, methods:{ playFn(id){ this.$router.push({ name:'play', query:{ id:id } }); console.log(id); }, getComment(id){ this.$router.push({ name:'comment', query:{ id } }) } }}</script>
四、具体页面实现
1、Layout组件相关
views/Layout/index.vue
<template> <div> <van-nav-bar :title="activeTitle" fixed/> <div class="main"> <keep-alive include="Home,Search"> <router-view></router-view> </keep-alive> </div> <van-tabbar v-model="active"> <van-tabbar-item icon="home-o" to="/layout/home">首页</van-tabbar-item> <van-tabbar-item icon="search" to="/layout/search">搜索</van-tabbar-item> </van-tabbar> </div></template><script>import { ref } from 'vue';export default { name:'Layout', data(){ return { activeTitle:this.$route.meta.title, } }, setup() { const active = ref(0); return { active, }; }, // 通过监听路由切换 watch:{ $route(){ this.activeTitle = this.$route.meta.title } }}</script><style scoped> .main { padding-top: 56px; padding-bottom: 66px; }</style>
2、Home组件相关
① 封装home相关axios请求
api/home.js
import request from "@/untils/request";// 推荐音乐export const hotMusic = (params)=>request({url:'/personalized',params})// 最新音乐export const newMusic = (params)=>request({url:'/personalized/newsong',params})
② Home组件代码
views/Home/index.vue
<template> <div> <p class="title">推荐歌单</p> <van-row gutter="10" > <van-col span="8" v-for="m in hotMusic" :key="m.id"> <van-image width="100%" height="3rem" :src="m.picUrl"/> <p class="song_name">{{m.name}}</p> </van-col> </van-row> <p class="title">最新音乐</p> <SongItem v-for="n in newMusic" :key="n.id" :name="n.name" :autor="n.song.artists[0].name + n.name" :id="n.id"></SongItem> </div></template><script>import SongItem from "@/components/songItem.vue";import {hotMusicAPI,newMusicAPI} from "@/api";export default { name:'Home', data(){ return { hotMusic:[], newMusic:[], } }, components:{SongItem}, async created(){ // 获取推荐歌曲 const resHot= await hotMusicAPI({limit:6}) this.hotMusic = resHot.data.result; // 获取最新音乐 const resNew = await newMusicAPI({limit:20}); this.newMusic = resNew.data.result; },}</script><style>/* 标题 */.title { padding: 0.266667rem 0.24rem; margin: 0 0 0.24rem 0; background-color: #eee; color: #333; font-size: 15px;}/* 推荐歌单 - 歌名 */.song_name { font-size: 0.346667rem; padding: 0 0.08rem; margin-bottom: 0.266667rem; word-break: break-all; text-overflow: ellipsis; display: -webkit-box; /** 对象作为伸缩盒子模型显示 **/ -webkit-box-orient: vertical; /** 设置或检索伸缩盒对象的子元素的排列方式 **/ -webkit-line-clamp: 2; /** 显示的行数 **/ overflow: hidden; /** 隐藏超出的内容 **/}</style>
3、Search组件相关

5、Play组件相关
① 封装play相关axios请求
import request from "@/untils/request";//获取音乐播放地址export const getSongById = (params)=>request({url:"/song/url/v1",params});//获取歌词export const getLyricById = (params)=>request({url:'/lyric',params});//获取歌曲详情export const getMusicById = (params)=>request({url:'/song/detail',params})
②Play组件代码

6、API统一出口
API/index.js
// 统一出口import {hotMusic,newMusic} from "@/api/home";import {hotSearch,keywordSearch} from "@/api/search";import { getSongById,getLyricById,getMusicById} from "@/api/play";import {getComment} from "@/api/comment";//导出推荐歌单方法export const hotMusicAPI = hotMusic//导出新歌方法export const newMusicAPI = newMusic//导入热搜export const hotSearchAPI = hotSearch;//导入关键词搜索export const keywordSearchAPI = keywordSearch;//播放音乐export const getSongByIdAPI = getSongById;//获取歌词export const getLyricByIdAPI = getLyricById;//获取歌曲详情export const getMusicByIdAPI = getMusicById;//获取评论export const getCommentAPI = getComment;
五、Play和Comment组件详解
在做项目的过程中,感觉Play组件歌词同步逻辑有点复杂,还有Comment组件上拉和下拉刷新也有点难,因此专门写了两篇详解,可以看一下~~~
