javascript - 将数据从承诺传递到工作线程

Question

嗨，我在将数据从承诺传递到工作线程时遇到问题。

我想将“数据”传递给工作线程并从工作线程传递给主线程。

我收到此错误：UnhandledPromiseRejectionWarning: TypeError [ERR_INVALID_ARG_TYPE]：“数据”参数必须是字符串类型或 Buffer、TypedArray 或 DataView 的实例。收到未定义。

下面是我的代码：

const { isMainThread, parentPort, Worker } = require("worker_threads");
const fs = require("fs");
const crypto = require("crypto");
const { join } = require("path");

const workLoad = async () => {
  return new Promise((resolve, reject) => {
    try {
      const firstArg = process.argv[2];
      const secondArg =
        process.argv[3] ?? Math.random().toString(36).substring(8) + ".txt";

      const encodedSha256 = crypto
        .createHash("sha256")
        .update(firstArg)
        .digest("hex");
      const base64 = Buffer.from(secondArg).toString("base64");

      const encodeData = `${encodedSha256}\n${base64}`;

      fs.writeFileSync(join(firstArg, secondArg), encodeData, {
        encoding: "utf-8",
      });
      const data = fs.readFileSync(join(firstArg, secondArg), {
        encoding: "utf-8",
      });
      resolve(data);
    } catch (error) {
      reject(error);
    }
  });
};

if (isMainThread) {
  const worker = new Worker(__filename);
  worker.on("message", (message) => console.log(message));
} else {
  workLoad().then((res) => parentPort.postMessage(res));
}
