• 当前 Bug 的表现（可附上截图）

开发好的功能，在2019-01-08那天在真机上还能正常播放，今天不能在真机上正常播放了。但是目前在微信开发者工具中正常播放

• 预期表现

希望正常播放

• 复现路径

• 提供一个最简复现 Demo

playAudio() {

let audioCtx = wx.createInnerAudioContext();

let src = this.data.tempPath;

console.log(src);

audioCtx.src = src;

this.setData({

‘audioCtx’: audioCtx,

‘currentDuration’: ‘00:00’,

‘percentage’: 0

});

audioCtx.play();

audioCtx.onPlay(() => {

let totalTime = this.data.duration;

let count = 0;

this.setData({

‘play’: true

});

let audio = setInterval(() => {

if (count >= totalTime) {

audioCtx.pause();

clearInterval(audio);

this.setData({

‘play’: false,

‘percentage’: 100

});

} else {

let showDuration;

count++;

let min = parseInt(count / 60);

let senconds = Math.ceil(count % 60);

let newMin, newSenconds;

if (min < 10) {

newMin = ‘0’ + min;

} else {

newMin = min;

}

if (senconds < 10) {

newSenconds = ‘0’ + senconds;

} else {

newSenconds = senconds;

}

showDuration = newMin + ‘:’ + newSenconds;

this.setData({

‘currentDuration’: showDuration,

‘percentage’: (count / totalTime) * 100

});

}

}, 1000);

this.setData({

‘audioInterval’: audio

});

})

},
