uni.createInnerAudioContext() 这个音频要放在接口前，IOS才能发出声音

let src = '/static/ok.mp3'; //扫码成功
let src2 = '/static/no.mp3'; //扫码错误
let src3 = '/static/phwc.mp3'; //配货完成
let src4 = '/static/cfph.mp3'; //重复配货
let src5 = '/static/hpcl.mp3'; //货配错了
const Audio = uni.createInnerAudioContext();
Audio.autoplay = true;

uni.request({
