wx.getBackgroundAudioManager的referrerPolicy设置线上不生效，开发者工具和开发版在真机都是OK的

audioCtx.value = wx.getBackgroundAudioManager();
    audioCtx.value.referrerPolicy = 'origin';
    audioCtx.value.title = audio.value.name;
    audioCtx.value.coverImgUrl = props.coverImgUrl;
    audioCtx.value.src = audio.value.url;
    audioCtx.value.play();
