      },
      method: 'post',

        wx.showToast({
          title: "上传成功",

        })
        that.setData({
          avatarUrl: res.data
        })


      },
      fail: function (err) {
        wx.showToast({
          title: "上传失败",
          icon: "none",
          duration: 2000
        })
      },
      complete: function (result) {}
    })
    
  },

3.如果没有弹窗，调整一下版本
