- 当前 Bug 的表现（可附上截图）

- 预期表现

- 复现路径

- 提供一个最简复现 Demo

function getImageInfo(url) {

  return new Promise((resolve, reject) => {

    wx.getImageInfo({

      src: url,

      success: resolve,

      fail: reject,

    })

  })

} //----------------------这个地址这样获取的----------------

  wx.cloud.getTempFileURL({

          fileList: [this.data.bgfileID],

          success: res => {

            // get temp file URL

            console.log("dowload file OK222!!!!>>>>")

            console.log(res.fileList[0].tempFileURL)

            console.log("dowload file OK222!!!!>>>>")

            this.setData({

              mydrawbg: res.fileList[0].tempFileURL,  //切换分享的背景

            })

          },

          fail: err => {

            // handle error

          }

        })

      }

是要设軒不较验域吗
