问对象存储时手机用流量无法上传图片，报错：{error：'error', header: {}}？

this.cos.sliceUploadFile({
  Bucket: environment.txyun.bucket,
  Region: environment.txyun.region,
  Key: storeAs,
  Body: file
}, function (err, data) {
  vm.loadingService.hide();
  if (err) {
    console.error(JSON.stringify(err));
    alert(JSON.stringify(err));
    reject('update img error');
  } else {
    const url = `${environment.txyun.urlStr}` + data.Key;
    console.log(url);
    resolve(url);
  }
});
