uniapp使用uni.createInnerAudioContext()实现在app 小程序 h5有声书的播放
实现读书软件的听书功能，适配app，小程序，h5
实现效果展示功能带你包括： 章节，倒计时，上一章，下一章，播放，暂停，倍速：
uniapp官方uni.createInnerAudioContext()的文档地址：官网文档参考地址
首先分步骤介绍功能：
- 章节（这个调取接口遍历数据就可以，弹出层的形式展示）
- 倒计时
- 上一章
- 下一章
- 播放
- 暂停
- 倍速
我这里页面嵌入一个audio的组件 ，组件名称audio
components: {Audio},
data() {
return {
sourceList:[], //章节的数据
bookImg: '', //图书的封面图
bookName:'',//书名
chapterName: '', //章节名称
chapterUrl:'',//播放的章节地址
id: null, //书的id
itemId:'', //章节id
}
},
<template>
<view class="content">
<view class="" v-if="sourceList.length > 0">
<Audio @handleId='handleId' :sourceList='sourceList' :bookResourceId='bookResourceId' :bookName='bookName' :bookImg='bookImg' :id='id' :wxId='id' :chapterName='chapterName' :chapterUrl='chapterUrl'></Audio>

首先进入页面初始化方法：
mounted() {
let that = this
that.initData()
},
initData() {
let that = this
// 页面加载设置当前播放章节的播放信息
this.bgAudioMannager = uni.createInnerAudioContext(); //只创建一次之后都是通过this.bgAudioMannager获取
this.bgAudioMannager.coverImgUrl = this.bookImg
this.bgAudioMannager.title = this.chapterName
this.bgAudioMannager.src = this.chapterUrl
// this.bgAudioMannager.playbackRate = 1.0 默认倍速为1.0
this.newId = this.id
this.duration = this.bgAudioMannager.duration
this.currentTime = this.bgAudioMannager.currentTime
this.currentId = this.id
this.startTime = this.getDate()
this.bgAudioMannager.onPlay(() => {
console.log('开始播放');
});
this.bgAudioMannager.onStop(() => {
console.log('停止播放');
});
this.bgAudioMannager.onPause(() => {
console.log('暂停播放');
});
this.bgAudioMannager.onEnded(() => {
//初始化 需要的参数
console.log('自然播放结束事件');
// this.nextMusic()
});
this.bgAudioMannager.onError((res) => {
console.log(res.errMsg);
console.log(res.errCode);
});
// 重要 缺失 音频进入可以播放状态
this.bgAudioMannager.onCanplay(() => {
this.currentTime = this.bgAudioMannager.currentTime
this.duration = this.bgAudioMannager.duration
console.log("可播放状态")
if (this.bgAudioMannager.duration) {
this.duration = this.bgAudioMannager.duration
console.log(this.bgAudioMannager.duration)
}
})
this.bgAudioMannager.play()
//音频进度更新事件
this.bgAudioMannager.onTimeUpdate(() => {
// console.log("开始监听")
/*
判断是否点击过进度条，若点击过，则不要对当前进度条时间current赋currentTime的值
因为音频进度更新事件运行频率过快，两个时间会引起冲突，
因此需要通过设置开关，判断seek真假，若seek为假则未点击进度条，若seek为真则跳过此次赋值并修改seek值重置为假
*/
if (!this.seek) {
this.currentTime = this.bgAudioMannager.currentTime
} else {
console.log("修改一次进度条")
// this.audio.seek(this.current_tmp)
// this.current = this.current_tmp
console.log(this.currentTime)
this.seek = false
}
if (this.bgAudioMannager.duration) {
this.duration = this.bgAudioMannager.duration
}
})
this.bgAudioMannager.onEnded(() => {
console.log('播放结束')
this.nextMusic()
});
},
如果需要页面返回的时候暂停音频：
onUnload() {
// clearInterval(timeSet); //停止调用
this.bgAudioMannager.pause()
this.newTime = 0;
this.playStatus = false //暂停播放的状态
this.bgAudioMannager.src = '' //当设置了新的 src 时，会自动开始播放
},
destroyed() {
this.bgAudioMannager.pause()
this.endTime = this.getDate()
},
点击进度条跳转到指定位置：
// 点击进度条
clickSeek(val) {
this.currentTime = val
this.bgAudioMannager.seek(val)
},
播放功能
playOrpause() {
//根据播放状态进行播放还是暂停
if (this.playStatus) {
this.bgAudioMannager.pause()
this.playStatus = false
} else {
this.bgAudioMannager.play()
this.playStatus = true
}
},
上一章和下一章，我们的章节目录结构是两层，逻辑是根据点击的进来的章节id去章节数组中找对应的章节，然后取他的上一节点或者下一节点，注意点：要把拿到的id替换掉当前的id
//上一首
lastMusic() {
let that = this
var currentIndex = null
var lastIndex = null
var currentIdx = null
this.bgAudioMannager.pause()
currentIndex = this.sourceList.findIndex((profile) => profile.id == that.id)
if (currentIndex == null || currentIndex == -1) {
this.sourceList.forEach((item, index) => {
//看当前id是否在子章节当中
currentIdx = item.twoLevelChapter.findIndex((item1) => item1.id == this.id)
lastIndex = item.twoLevelChapter.length - 1
//如果在父章节中找到，直接拿当前章节上一章节，通过下标-1的信息
if (currentIdx != -1) {
if (currentIdx != 0) {
this.bgAudioMannager.title = item.twoLevelChapter[currentIdx - 1].chapterName
this.bgAudioMannager.coverImgUrl = item.twoLevelChapter[currentIdx - 1].chapterUrl
this.bgAudioMannager.src = item.twoLevelChapter[currentIdx - 1].chapterUrl
that.newId = item.twoLevelChapter[currentIdx - 1].id
that.$emit('handleId', this.newId)
this.nextPlay = true

this.bgAudioMannager.play()
