做门户型网站要多少钱上海网站推广公司

需求是：进入页面的时候是先有背景音乐，发送问题请求回答的时候会返回文字和音频，前端要把音频读出来，并且把背景音乐停止，读完音频后再打开背景音乐

一开始用的直接base64直接拼接在地址后 真机放不了

const innerAudioContext = wx.createInnerAudioContext();
innerAudioContext.src ='data:audio/mp3;base64,'+ 请求获取的base64编码的mp3格式文件;
innerAudioContext.play();

下面这个方式亲测有效

//背景音乐playBackground(innerAudioContext, stop) {// const innerAudioContext = uni.createInnerAudioContext();innerAudioContext.autoplay = true;innerAudioContext.loop = true; //循环播放innerAudioContext.src = 'https://wealthgod.oss-cn-beijing.aliyuncs.com/caishen/backgroundmq3.mp3';innerAudioContext.onPlay(() => {console.log('开始播放');});innerAudioContext.onStop((res) => {innerAudioContext.stop()//播放停止，销毁该实例innerAudioContext.destroy()});innerAudioContext.onEnded((res) => {innerAudioContext.play();});},
//回答音频			
playerAnswer(url) {const backgroundAudioManager = wx.getBackgroundAudioManager()var number = Math.random()const audioPath = wx.env.USER_DATA_PATH + '/new' + number + '.mp3'const fs = wx.getFileSystemManager();fs.writeFile({filePath: audioPath,data: url,encoding: 'base64',success(res) {backgroundAudioManager.title = '财神'backgroundAudioManager.src = audioPathbackgroundAudioManager.onEnded((res) => {backgroundAudioManager.src = 'https://wealthgod.oss-cn-beijing.aliyuncs.com/caishen/backgroundmq3.mp3';});},})},this.playBackground(uni.createInnerAudioContext())this.playerAnswer(surl)//surl是背景地址

//manifest.json中/* 小程序特有相关 */"mp-weixin" : {     "requiredBackgroundModes" : [ "audio" ],},
