HarmonyOS 鸿蒙Next 未什么taskpool和worker线程中无法获取宿主线程中的数据

代码如下。

@Entry
@Component
struct Index {
  @State message: string = ‘Hello World’;

  aboutToAppear(): void {
    // 线程
    // const workerInstance = new worker.ThreadWorker(‘entry/ets/workers/Worker.ets’);
    // Info.deviceId = “123456789”
    // workerInstance.postMessage(Info.deviceId);
    // workerInstance.onmessage = (data: MessageEvent<string>): void => {
    //   console.log(data.data.toString());
    // }
  }

  build() {
    Row() {
      Button(“测试线程”).onClick(() => {
        // try {
        //   const downloadPath = Environment.getUserDownloadDir();
        //   console.info(Success to getUserDownloadDir: ${downloadPath});
        //   let fileList: string[] = fileIo.listFileSync(downloadPath);
        //   fileList.forEach((file, index) => {
        //     console.log(file);
        //   })
        // } catch (e) {
        //   console.error(异常：${e.message});
        //   ToastUtil.showToast(${e.message});
        // }
        try{
          Info.deviceId = “123456789”
          let task: taskpool.Task = new taskpool.Task(taskSum, 1, 2);
          taskpool.execute(task);
          console.info(执行完成);
        }catch(e) {
          console.error(失败：${e.message})
        }
        console.info(“主线程不阻塞”);
      })
    }.height(‘100%’)
  }
}

@Concurrent
function taskSum(num1: number, num2: number) {
  setTimeout(() => {
    let sum = num1 + num2;
    console.info(总计：${sum}, deviceId: ${Info.deviceId});
  }, 2000);
}

打印Info.deivceId时是空值。
