Vue实现仿音乐播放器11-实现访问百度音乐API实现播放音乐功能

时间：2020-02-25 10:18:13

场景

从今日推荐页面点击某首歌曲会将这首歌曲的songid通过路由传递到播放界面，

播放界面调用百度音乐接口实现数据的获取以及音乐的播放。

效果

实现

配置路由

首先在pages目录下新建musicplay.vue作为音乐播放的页面，

然后在router下的index.js中中配置路由。

routes: [{path:"/musicplay",name:"MusicPlay",component:MusicPlay},

来到今日推荐页面，配置页面跳转

跳转到音乐播放组件并将当前音乐的songid通过路由参数传递过去。

<div class="scroller"><router-link tag="div" :to="{name:'MusicPlay',params:{songid:item.song_id}}" class="card url" v-for="(item,index) in todayRecommend" :key="index"><div class="album"><img :src="item.pic_big" :alt="item.title"><div class="name">{{ item.title }}</div></div></router-link></div>

同理将其他页面，要实现播放的页面组件也配置跳转到音乐播放组件，并将要播放的音乐组件的songid传递过去。

实现音乐播放界面

百度音乐API播放说明：

例：method=baidu.ting.song.play&songid=877578

例：method=baidu.ting.song.playAAC&songid=877578

参数：songid = 877578 //歌曲id

注：关于使用file_link不能播放的问题，是因为百度使用Http中的Referer头字段来防止盗链，在HTML文件中

加上 <meta name=”referrer” content=”never”>这一句让发送出去的Http包都不含Referer字段

来到musicplay.vue

CSS样式

页面布局

实现歌词滚动功能

在components目录下新建LRC.vue

<template lang="html"><div class="lrcContainer"><div class="lrc" ref="lrc">{{ getAllKey }}<pclass="lrc-p":class="{active:parseInt(currentTime) >= keyArr[index] && parseInt(currentTime) < keyArr[index+1]}"v-for="(item,key,index) in lrcData":key="index">{{ item }}{{ srcollLrc(key,index) }}</p></div></div></template><script>export default {name:"lrc",data(){return{lrc:{},lrcData:{},keyArr:[]}},props:{songid:{type:[String,Number],default:""},currentTime:{type:[String,Number],default:0},durationTime:{type:[String,Number],default:0}},mounted(){const LRCUrl = this.HOST+"/v1/restserver/ting?method=baidu.ting.song.lry&songid="+this.songid;this.$axios.get(LRCUrl).then(res => {this.lrc = res.data// 数据格式处理var lyrics = res.data.lrcContent.split("\n");var lrcObj = {};for(var i = 0 ;i<lyrics.length;i++){var lyric = decodeURIComponent(lyrics[i]);var timeReg = /\[\d*:\d*((\.|\:)\d*)*\]/g;var timeRegExpArr = lyric.match(timeReg);if(!timeRegExpArr)continue;var clause = lyric.replace(timeReg,'');for(var k = 0,h = timeRegExpArr.length;k < h;k++) {var t = timeRegExpArr[k];var min = Number(String(t.match(/\[\d*/i)).slice(1)),sec = Number(String(t.match(/\:\d*/i)).slice(1));var time = min * 60 + sec;lrcObj[time] = clause;}}this.lrcData = lrcObj;}).catch(error => {console.log(error);})},computed:{getAllKey(){for(var i in this.lrcData){this.keyArr.push(i);}}},methods:{srcollLrc(key,index){const lrcDiv = this.$refs.lrcif(key < this.currentTime && key > this.currentTime - (this.keyArr[index+1] - this.keyArr[index])){lrcDiv.style.top = -((index-2)*30)+"px"}}}}</script><style scoped>.lrcContainer{width: 100%;height: 150px;overflow: hidden;position: relative;}.lrc{width: 100%;position: absolute;top: 0;}.active{color: red !important;}.lrc-p{height: 30px;line-height: 30px;}.up30{margin-top: -30px;}</style>

在musicplay.vue显示歌词滚动

<div class="song-info-img"><img :src="currentUrl.songinfo.pic_big"><LRC :durationTime="durationTime" :currentTime="currentTime" :songid="this.$route.params.songid"/></div>

在musicplay.vue异步操作

// 异步操作const LRC = ponent("lrc",(resolve)=>require(["../components/LRC"],resolve))添加监听methods:{addEventListeners(){this.$refs.player.addEventListener('timeupdate', this._currentTime),this.$refs.player.addEventListener('canplay', this._durationTime)},removeEventListeners: function () {this.$refs.player.removeEventListener('timeupdate', this._currentTime)this.$refs.player.removeEventListener('canplay', this._durationTime)},_currentTime(){this.currentTime = this.$refs.player.currentTime// currentTime是audio标签提供的获取当前播放时间的方法},_durationTime(){this.durationTime = this.$refs.player.duration// duration是audio标签提供的获得歌曲播放整体时间的方法}}

实现下载功能

百度音乐API下载说明：

例：method=baidu.ting.song.downWeb&songid=877578&bit=24&_t=1393123213

参数： songid = 877578//歌曲id

bit = 24, 64, 128, 192, 256, 320 ,flac//码率

_t = 1430215999,, //时间戳

我们在请求百度音乐的API后输出返回的数据可以看到

歌曲的链接为：

返回数据下的bitrate下的show_link

所以我们几将audio的src属性设为

<div class="song"><audio ref="player" :src="currentUrl.bitrate.show_link" controls autoplay></audio></div>

所以我们点击播放组件的右边的三个点，选择下载，就可以实现下载了。
