需求是：進(jìn)入頁(yè)面的時(shí)候是先有背景音樂(lè)，發(fā)送問(wèn)題請(qǐng)求回答的時(shí)候會(huì)返回文字和音頻，前端要把音頻讀出來(lái)，并且把背景音樂(lè)停止，讀完音頻后再打開(kāi)背景音樂(lè)

一開(kāi)始用的直接base64直接拼接在地址后 真機(jī)放不了

const innerAudioContext = wx.createInnerAudioContext();
innerAudioContext.src ='data:audio/mp3;base64,'+ 請(qǐng)求獲取的base64編碼的mp3格式文件;
innerAudioContext.play();

下面這個(gè)方式親測(cè)有效

//背景音樂(lè)playBackground(innerAudioContext, stop) {// const innerAudioContext = uni.createInnerAudioContext();innerAudioContext.autoplay = true;innerAudioContext.loop = true; //循環(huán)播放innerAudioContext.src = 'https://wealthgod.oss-cn-beijing.aliyuncs.com/caishen/backgroundmq3.mp3';innerAudioContext.onPlay(() => {console.log('開(kāi)始播放');});innerAudioContext.onStop((res) => {innerAudioContext.stop()//播放停止，銷毀該實(shí)例innerAudioContext.destroy()});innerAudioContext.onEnded((res) => {innerAudioContext.play();});},
//回答音頻
