HarmonyOS 鸿蒙Next中文件上传会触发通知栏显示问题

HarmonyOS 鸿蒙Next中文件上传会触发通知栏显示问题 鸿蒙beta3系统手机每次执行文件上传都会触发一次通知栏的上传成功通知显示。调用的api是:request.agent.create的方法

问题:为啥会触发通知栏。怎样能去掉呢？

let config: request.agent.Config = {
  action: request.agent.Action.UPLOAD,
  url: URL_LOG_FILE_UPLOAD, // 需要手动将 url 替换为真实服务器的 HTTP 协议地址 
  title: 'upload', 
  description: 'Sample code for event listening',
  mode: request.agent.Mode.BACKGROUND, 
  overwrite: false,
  method: "POST", 
  data: attachments,
  network: request.agent.Network.ANY,
  metered: false, 
  roaming: true, 
  retry: true, 
  redirect: true,
  index: 0,
  begins: 0, 
  ends: -1, 
  gauge: true, 
  precise: false, 
}; 
let createOnCallback = (progress: request.agent.Progress) => {
  console.info('upload task progress.'+progress.state);
} 
fs.unlink(logFilePath) //上传完成-删除文件 
console.info('上传完成-删除文件:'+logFilePath) 
}; 
try { 
  request.agent.create(getContext(), config)
    .then((task: request.agent.Task) => { 
      task.on('completed', createOnCallback); 
      console.info(`Succeeded in creating a upload task. result: ${task.tid}`);
      task.start(); 
    }).catch((err: BusinessError) => { 
      console.error(`Failed to create a upload task, Code: ${err.code}, message: ${err.message}`);
    });
} catch (err) { 
  console.error(`Failed to create a upload task, err: ${err}`); 
  fs.unlink(logFilePath) 
  console.info('上传异常-删除文件:'+logFilePath)
}
