按住录音 startRecode: function () { const options = { duration: 10000,//指定录音的时长，单位 ms sampleRate: 16000,//采样率 numberOfChannels: 1,//录音通道数 encodeBitRate: 96000,//编码码率 format: ‘mp3’, frameSize: 50,//指定帧大小，单位 KB } recorderManager.start(options); }, endRecode:function() { recorderManager.stop(); var s = this; recorderManager.onStop((res) => { let audioFilePath = res.tempFilePath console.log(res) console.log(audioFilePath) setTimeout(function(){ wx.uploadFile({ url: config.service.uploadUrl, filePath: audioFilePath, header: { miniProgram: “ios” }, name: ‘file’, success: function (res) { var data = res.data; console.log(res); if (data.states == 1) { var cEditData = s.data.editData; cEditData.recodeIdentity = data.identitys; s.setData({ editData: cEditData }); } else { wx.showModal({ title: ‘提示’, content: data.message, showCancel: false, success: function (res) {

            }
          });
        }
        wx.hideToast();
      },
      fail: function (res) {
        console.log(res);
        wx.showModal({
          title: '提示',
          content: "网络请求失败，请确保网络是否正常",
          showCancel: false,
          success: function (res) {

          }
        });
        wx.hideToast();
      }
    });
  },2000)
})

}, 最后会报"Cannot read property ‘mime’ of null"这个错误 请问这是为何啊
