  },  //开始录音  openRecording: function() {    var that = this;    wx.getSystemInfo({      success: function(res) {        that.setData({          shutRecordingdis: “block”,          openRecordingdis: “none”        })      }    })    const options = {      duration: 60000, //指定录音的时长,单位 ms,最大为10分钟(600000),默认为1分钟(60000)      sampleRate: 16000, //采样率      numberOfChannels: 1, //录音通道数      encodeBitRate: 96000, //编码码率      format: ‘mp3’, //音频格式,有效值 aac/mp3      frameSize: 50, //指定帧大小,单位 KB    }    //开始录音计时       that.recordingTimer();    //开始录音    recorderManager.start(options);    recorderManager.onStart(() => {      console.log(‘。。。开始录音。。。’)    });    //错误回调    recorderManager.onError((res) => {      console.log(res);    })  },  //结束录音  shutRecording: function() {    var that = this;
