结构

先来看看页面结构

    
    

<view class="tab">
  <view class="tab-item {{tab==0?'active':''}}" bindtap="changeItem" data-item="0">音乐推荐view>

其中一些代码可以使用 wx:for 循环创建，这边为了简单明了就没有循环创建

核心代码

音乐数据

🆗，接下来创建播放列表数据

data: {
    item: 0,
    tab: 0,
    // 播放列表数据
    playlist: [{
      id: 1,
      title: 'Always Online',
      singer: '林俊杰',
      src: 'http://localhost:3000/林俊杰 - Always Online.mp3',
      coverImgUrl: '/images/jj.jpeg'
    }, {
      id: 2,
      title: '不得不爱',
      singer: '潘玮柏、弦子',
      src: 'http://localhost:3000/潘玮柏、弦子 - 不得不爱.mp3',
      coverImgUrl: '/images/pwb.jpg'
    }, {
      id: 3,
      title: '大城小爱',
      singer: '王力宏',
      src: 'http://localhost:3000/王力宏 - 大城小爱.mp3',
      coverImgUrl: '/images/wlh.jpeg'
    }, {
      id: 4,
      title: '偏爱',
      singer: '张芸京',
      src: 'http://localhost:3000/张芸京 - 偏爱.mp3',
      coverImgUrl: '/images/pa.jpeg'
    }],
    state: 'paused',
    playIndex: 0,
    play: {
      currentTime: '00:00',
      duration: '00:00',
      percent: 0,
      title: '',
      singer: '',
      coverImgUrl: '/images/cover.jpg',
    }
  },

切换功能

来实现一些页面之间简单的切换

 // 页面切换
  changeItem: function (e) {
    this.setData({
      item: e.target.dataset.item,
    })
  },
  // tab切换
  changeTab: function (e) {
    this.setData({
      tab: e.detail.current
    })
  },

播放功能

// 实现播放器播放功能
  audioCtx: null,
  onReady: function () {
    this.audioCtx = wx.createInnerAudioContext()
    // 默认选择第1曲
    this.setMusic(0)
    var that = this
    // 播放进度检测
    this.audioCtx.onError(function () {
      console.log('播放失败：' + that.audioCtx.src)
    })
    // 播放完成自动换下一曲
    this.audioCtx.onEnded(function () {
      that.next()
    })
    // 自动更新播放进度
    this.audioCtx.onPlay(function () {})
    this.audioCtx.onTimeUpdate(function () {
      that.setData({
        'play.duration': formatTime(that.audioCtx.duration),
        'play.currentTime': formatTime(that.audioCtx.currentTime),
        'play.percent': that.audioCtx.currentTime / that.audioCtx.duration * 100
      })
    })
    // 格式化时间
    function formatTime(time) {
      var minute = Math.floor(time / 60) % 60;
      var second = Math.floor(time) % 60
      return (minute < 10 ? '0' + minute : minute) + ':' + (second < 10 ? '0' + second : second)
    }
  },
  // 音乐播放
  setMusic: function (index) {
    var music = this.data.playlist[index]
    this.audioCtx.src = music.src
    this.setData({
      playIndex: index,
      'play.title': music.title,
      'play.singer': music.singer,
      'play.coverImgUrl': music.coverImgUrl,
      'play.currentTime': '00:00',
      'play.duration': '00:00',
      'play.percent': 0
    })
  },

  // 播放按钮
  play: function () {
    this.audioCtx.play()
    this.setData({
      state: 'running'
    })
  },

  // 暂停按钮
  pause: function () {
    this.audioCtx.pause()
    this.setData({
      state: 'paused'
    })
  },

  // 下一曲按钮
  next: function () {
    var index = this.data.playIndex >= this.data.playlist.length - 1 ? 0 : this.data.playIndex + 1
    this.setMusic(index)
    if (this.data.state === 'running') {
      this.play()
    }
  },

接下来就是一些必不可少的小功能了

// 滚动条调节歌曲进度
  sliderChange: function (e) {
    var second = e.detail.value * this.audioCtx.duration / 100
    this.audioCtx.seek(second)
  },

  // 播放列表换曲功能
  change: function (e) {
    this.setMusic(e.currentTarget.dataset.index)
    this.play()
  }

🆗，最后的就剩下node服务了，这边node服务只是为了挂载音乐文件这些静态资源。
这边我也会将服务端上传到本篇博客，把自己需要的MP3或MP4格式文件放入到htdocs中即可。
这边怕引起版权纠纷和维权问题就不把歌曲文件放入其中
在这里插入图片描述

node 下面代码存放在 index.js 中请记得使用 yarn 或者 npm 安装以下的引入文件

var express = require('express')
var serveIndex = require('serve-index')
var serveStatic = require('serve-static')
var multiparty = require('multiparty')
var finalhandler = require('finalhandler')
var util = require('util')

var LOCAL_BIND_PORT = 3000
var app = express()

app.post('/upload', function (req, res) {
  var form = new multiparty.Form()
  form.encoding = 'utf-8'
  form.uploadDir = './htdocs/upfile'
  form.maxFilesSize = 4 * 1024 * 1024
  form.parse(req, function (err, fields, files) {
    if (err) {
      console.log('parse error: ' + err)
    } else {
      console.log('parse files: ' + JSON.stringify(files))
    }
    res.writeHead(200, { 'content-type': 'text/plain;charset=utf-8' })
    res.write('received upload')
    res.end()
  })
})

var serve = serveStatic('./htdocs')
app.use('/', serveIndex('./htdocs', { 'icons': true }))

app.get('/*', function (req, res) {
  serve(req, res, finalhandler(req, res))
});

// console.log(`Start static file server at ::${LOCAL_BIND_PORT}, Press ^ + C to exit`)
console.log('启动成功')

app.listen(LOCAL_BIND_PORT)
// 监听3000端口
// app.listen(3000, () => {
//   console.log('server running at http://127.0.0.1:3000')
// })

最后附上完整代码

// pages/index/index.js
Page({

  /**

  data: {
    item: 0,
    tab: 0,
    // 播放列表数据

      title: '不得不爱',
      singer: '潘玮柏、弦子',
      src: 'http://localhost:3000/潘玮柏、弦子 - 不得不爱.mp3',

    }, {

      })
    })
    // 格式化时间
    function formatTime(time) {
      var minute = Math.floor(time / 60) % 60;
      var second = Math.floor(time) % 60

  },

  // 播放按钮
  play: function () {

  // 暂停按钮
