Vue 实现音乐播放功能

基础播放器实现

使用HTML5的<audio>标签结合Vue的响应式特性实现基础播放功能。在模板中添加<audio>元素并绑定ref：

<template>
  <audio ref="audioPlayer" :src="currentSong.url"></audio>
  <button @click="togglePlay">{{ isPlaying ? '暂停' : '播放' }}</button>
</template>

在Vue组件中控制播放状态：

export default {
  data() {
    return {
      currentSong: {
        url: 'https://example.com/song.mp3'
      },
      isPlaying: false
    }
  },
  methods: {
    togglePlay() {
      const player = this.$refs.audioPlayer
      this.isPlaying ? player.pause() : player.play()
      this.isPlaying = !this.isPlaying
    }
  }
}

进度条与时间显示

添加进度条显示和控制功能，使用<input type="range">绑定音频当前时间：

<input 
  type="range" 
  v-model="currentTime" 
  :max="duration"
  @input="seekTime"
>
<span>{{ formatTime(currentTime) }} / {{ formatTime(duration) }}</span>

在组件中添加相关逻辑：

data() {
  return {
    currentTime: 0,
    duration: 0
  }
},
mounted() {
  const player = this.$refs.audioPlayer
  player.addEventListener('timeupdate', () => {
    this.currentTime = player.currentTime
  })
  player.addEventListener('loadedmetadata', () => {
    this.duration = player.duration
  })
},
methods: {
  seekTime(e) {
    this.$refs.audioPlayer.currentTime = e.target.value
  },
  formatTime(seconds) {
    const mins = Math.floor(seconds / 60)
    const secs = Math.floor(seconds % 60)
    return `${mins}:${secs < 10 ? '0' : ''}${secs}`
  }
}

音量控制

添加音量控制滑块：

<input 
  type="range" 
  v-model="volume" 
  min="0" 
  max="1" 
  step="0.01"
  @input="setVolume"
>

组件中添加音量控制逻辑：

data() {
  return {
    volume: 0.7
  }
},
mounted() {
  this.$refs.audioPlayer.volume = this.volume
},
methods: {
  setVolume() {
    this.$refs.audioPlayer.volume = this.volume
  }
}

播放列表功能

实现多歌曲切换功能，创建播放列表数组：

data() {
  return {
    playlist: [
      { id: 1, title: '歌曲1', url: 'url1.mp3' },
      { id: 2, title: '歌曲2', url: 'url2.mp3' }
    ],
    currentIndex: 0
  }
},
computed: {
  currentSong() {
    return this.playlist[this.currentIndex]
  }
},
methods: {
  playSong(index) {
    this.currentIndex = index
    this.$nextTick(() => {
      this.$refs.audioPlayer.play()
      this.isPlaying = true
    })
  }
}

高级功能扩展

添加音频可视化效果需要Web Audio API：

setupVisualizer() {
  const audioCtx = new (window.AudioContext || window.webkitAudioContext)()
  const analyser = audioCtx.createAnalyser()
  const source = audioCtx.createMediaElementSource(this.$refs.audioPlayer)
  source.connect(analyser)
  analyser.connect(audioCtx.destination)

  const bufferLength = analyser.frequencyBinCount
  const dataArray = new Uint8Array(bufferLength)

  const draw = () => {
    requestAnimationFrame(draw)
    analyser.getByteFrequencyData(dataArray)
    // 使用Canvas绘制可视化效果
  }
  draw()
}

第三方库集成

考虑使用现成的Vue音频播放器库如vue-aplayer：

npm install vue-aplayer

基础用法示例：

import VueAplayer from 'vue-aplayer'

export default {
  components: {
    VueAplayer
  },
  data() {
    return {
      song: {
        title: '示例歌曲',
        artist: '艺术家',
        src: 'song.mp3',
        pic: 'cover.jpg'
      }
    }
  }
}

<vue-aplayer :music="song" autoplay/>

移动端适配

针对移动端浏览器需要特殊处理自动播放限制：

mounted() {
  document.addEventListener('click', this.initAudio, { once: true })
},
methods: {
  initAudio() {
    // 用户交互后初始化音频
    this.$refs.audioPlayer.load()
  }
}
