微信小程序音乐播放器开发

 <view class='audiosBox'>
  <view class="audioOpen" bindtap="listenerButtonPlay" wx:if="{{!isOpen}}">
   <image class='image2' src="/UploadFiles/2021-04-02/play.png">

js部分注意了：bug ios 播放时必须加title 不然会报错导致音乐不播放


//index.js
//获取应用实例
const bgMusic = wx.getBackgroundAudioManager()
const app = getApp()
 
Page({
 data: {
  isOpen: false,//播放开关
  starttime: '00:00', //正在播放时长
  duration: '06:41',  //总时长
  src:"http://ws.stream.qqmusic.qq.com/M500001VfvsJ21xFqb.mp3"
 },
 // 播放
 listenerButtonPlay: function () {
  var that = this
  //bug ios 播放时必须加title 不然会报错导致音乐不播放
  bgMusic.title = '此时此刻' 
  bgMusic.epname = '此时此刻'
  bgMusic.src = that.data.src;
  bgMusic.onTimeUpdate(() => { 
   //bgMusic.duration总时长 bgMusic.currentTime当前进度
   console.log(bgMusic.currentTime)
   var duration = bgMusic.duration; 
   var offset = bgMusic.currentTime; 
   var currentTime = parseInt(bgMusic.currentTime);
   var min = "0" + parseInt(currentTime / 60);
   var max = parseInt(bgMusic.duration);
   var sec = currentTime % 60;
   if (sec < 10) {
    sec = "0" + sec;
   };
   var starttime = min + ':' + sec;  /* 00:00 */
   that.setData({
    offset: currentTime,
    starttime: starttime,
    max: max,
    changePlay: true
   })
  })
  //播放结束
  bgMusic.onEnded(() => {
   that.setData({
    starttime: '00:00',
    isOpen: false,
    offset: 0
   })
   console.log("音乐播放结束");
  })
  bgMusic.play();
  that.setData({
   isOpen: true,
  })
 },
 //暂停播放
 listenerButtonPause(){
   var that = this
  bgMusic.pause()
  that.setData({
   isOpen: false,
  })
 },
 listenerButtonStop(){
  var that = this
  bgMusic.stop()
 },
 // 进度条拖拽
 sliderChange(e) {
  var that = this
  var offset = parseInt(e.detail.value);
  bgMusic.play();
  bgMusic.seek(offset);
  that.setData({
   isOpen: true,
  })
 },
 // 页面卸载时停止播放
 onUnload() {
  var that = this
  that.listenerButtonStop()//停止播放
  console.log("离开")
 },
})
