#鸿蒙通关秘籍#如何在HarmonyOS NEXT中使用Worker子线程解压文件？

// 创建Worker实例
let workerInstance = new worker.ThreadWorker('@decompressFile/ets/workers/Worker.ets');

// 向Worker线程发送消息
workerInstance.postMessage({ pathDir: this.pathDir, rawfileZipName: rawfileZipName });

// 在Worker.ets中接收消息
workerPort.onmessage = (e) => {
  let pathDir = e.data.pathDir;
  let rawfileZipName = e.data.rawfileZipName;

  fs.access(outFileDir).then((res) => {
    if (!res) {
      fs.mkdirSync(outFileDir);
    }
    zlib.decompressFile(`${pathDir}/${rawfileZipName}`, outFileDir, (errData) => {
      if (errData) {
        logger.error(`${errData.code}, ${errData.message}`);
      } else {
        workerPort.postMessage(outFileDir);
      }
    });
  }).catch((err) => {
    logger.error(`${err.message}, ${err.code}`);
  });
};
