同样的是因为小程序官网不保护audio组件了

音频组件的要求与限度

  1. 点击播放或者暂停
  2. 显示播放进度及总时长
  3. 通过图标变动显示以后音频所处状态（暂停/播放/加载中）
  4. 页面音频更新时刷新组件状态
  5. 全局有且只有一个音频处于播放状态
  6. 来到页面之后要主动进行播放并销毁音频实例

资料/属性/办法

让咱们开始吧????

uni-app Vue

  • 同样的先结构DOM构造
<view class="custom-audio">  <image v-if="audioSrc !== undefined && audioSrc !== null && audioSrc !== ''" @click="playOrStopAudio" :src="audioImg" class="audio-btn" />  <text v-else @click="tips" class="audio-btn">无音源</text>  <text>{{ fmtSecond(currentTime) }}/{{ fmtSecond(duration) }}</text></view>
  • 定义承受的组件
props: {  audioSrc: {    type: String,    default: ''  },},
  • 定义CustomAudio组件的初始化相干的操作，并给innerAudioContext的回调增加一些行为（之前Taro那篇咱们踩过的坑这里就间接上代码了）
import { formatSecondToHHmmss, afterAudioPlay, beforeAudioRecordOrPlay } from '../../lib/Utils'const iconPaused = '../../static/images/icon_paused.png'const iconPlaying = '../../static/images/icon_playing.png'const iconStop = '../../static/images/icon_stop.png'const iconLoading = '../../static/images/icon_loading.gif'// ...data() {  return {    audioCtx: null, // 音频上下文    duration: 0, // 音频总时长    currentTime: 0, // 音频以后播放的时长    audioImg: iconLoading, // 默认状态为加载中  }},watch: {  audioSrc: {    handler(newSrc, oldSrc) {      console.log('watch', newSrc, oldSrc)      this.audioImg = iconLoading      this.currentTime = 0      this.duration = 0      if (this.audioCtx === undefined) {        this.audioCtx = uni.createInnerAudioContext()        this.onTimeUpdate = this.audioCtx.onTimeUpdate        this.bindAuidoCallback(this.audioCtx)      } else {        this.audioCtx.src = newSrc      }      if (this.audioCtx.play) {        this.audioCtx.stop()        getApp().globalData.audioPlaying = false      }    }  }},mounted() {  this.audioCtx = uni.createInnerAudioContext()  this.audioCtx.src = this.audioSrc  this.audioCtx.startTime = 0  this.bindAuidoCallback(this.audioCtx)},methods: {  bindAuidoCallback(ctx) {    ctx.onTimeUpdate((e) => {      this.onTimeUpdate(e)    })    ctx.onCanplay((e) => {      this.onCanplay(e)    })    ctx.onWaiting((e) => {      this.onWaiting(e)    })    ctx.onPlay((e) => {      this.onPlay(e)    })    ctx.onPause((e) => {      this.onPause(e)    })    ctx.onEnded((e) => {      this.onEnded(e)    })    ctx.onError((e) => {      this.onError(e)    })  },  tips(){    uni.showToast({      title: '有效音源,请先录音',      icon: 'none'    })  },  playOrStopAudio() {    if (this.audioCtx === null) {      this.audioCtx = uni.createInnerAudioContext()      this.audioCtx.src = this.audioSrc      this.bindAuidoCallback(this.audioCtx)    }    if (this.audioCtx.paused) {      if (beforeAudioRecordOrPlay('play')) {        this.audioCtx.play()        this.audioImg = iconPlaying      }    } else {      this.audioCtx.pause()      afterAudioPlay()      this.audioImg = iconPaused    }  },  onTimeUpdate(e) {    console.log('onTimeUpdate', this.audioCtx.duration, this.audioCtx.currentTime)    if (this.audioCtx.currentTime > 0 && this.audioCtx.currentTime <= 1) {      this.currentTime = 1    } else if (this.currentTime !== Math.floor(this.audioCtx.currentTime)) {      this.currentTime = Math.floor(this.audioCtx.currentTime)    }    const duration = Math.floor(this.audioCtx.duration)    if (this.duration !== duration) {      this.duration = duration    }  },  onCanplay(e) {    if (this.audioImg === iconLoading) {      this.audioImg = iconPaused    }    console.log('onCanplay', e)  },  onWaiting(e) {    if (this.audioImg !== iconLoading) {      this.audioImg = iconLoading    }  },  onPlay(e) {    console.log('onPlay', e, this.audioCtx.duration)    this.audioImg = iconPlaying    if (this.audioCtx.duration > 0 && this.audioCtx.duration <= 1) {      this.duration = 1    } else {      this.duration = Math.floor(this.audioCtx.duration)    }  },  onPause(e) {    console.log('onPause', e)    this.audioImg = iconPaused  },  onEnded(e) {    console.log('onEnded', e)    if (this.audioImg !== iconPaused) {      this.audioImg = iconPaused    }    afterAudioPlay()  },  onError(e) {    uni.showToast({      title: '音频加载失败',      icon: 'none'    })    throw new Error(e.errMsg, e.errCode)  },  fmtSecond(sec) {    const { min, second } = formatSecondToHHmmss(sec)    return `${min}:${second}`  }},

同样的scss文件

<style lang="scss" scoped>.custom-audio {  border-radius: 8vw;  border: #CCC 1px solid;  background: #F3F6FC;  color: #333;  display: flex;  flex-flow: row nowrap;  align-items: center;  justify-content: space-between;  padding: 2vw;  font-size: 14px;  .audio-btn {    width: 10vw;    height: 10vw;    white-space: nowrap;    display: flex;    align-items: center;    justify-content: center;  }}</style>
