点击播放按钮，iOS端播放，onError回调里报错如下：

{errMsg: "playerErrCode:6, systemErrCode:403, domain:com.tencent.KSAudioPlayer.HTTP, description:未能完成操作。（com.tencent.KSAudioPlayer.HTTP错误403。）", errCode: 10002, src: "https://private-examine.oss-cn-shanghai.aliyuncs.com/digitcure/Sds/HJYY03.mp3"}

BackgroundAudioManager 已经设置referrerPolicy='origin',开发工具和微信安卓客户端上，防盗链音频可以播放成功，微信iOS客户端上播放不成功。
