node.js vanilla服务器中的重置请求队列

Question

我有一个程序，可以接受包含数字的机构的发布请求。我的程序检查是身体中的数字是否是质数。一切都是第一次，但是每次之后，该程序都会记住过去的帖子也请求检查。 如何重置请求队列，以便我的程序只会检查最新的帖子请求？

这是代码：

import { createServer } from "http";
import { parse } from "querystring";
import { url } from "inspector";
import { port } from "./config.js";
let body = "";
let checkNumber = true;
const PORT = process.env.PORT || port;

const server = createServer(async (req, res) => {
  res.statusCode = 200;
  res.setHeader("Content-Type", "text/html");
  const FORM_URLENCODED = "application/x-www-form-urlencoded";
  const POST_PATH = "api/numbers/prime/validate";
  const GET_PATH = "api/numbers/prime";

  if (req.headers["content-type"] === FORM_URLENCODED) {
    //console.log(req.method);
    if (req.method === "POST") {
      req.on("data", (chunk) => {
        body += chunk.toString();
      });
  }

  if (req.url === `/${POST_PATH}`) {
    let re = parse(body);

    await checkValuesInObject(re);
    console.log(checkNumber);
    res.end(`${checkNumber}`);
  }
  res.end();
});

server.listen(PORT, () => {
  console.log(`listening on port ${PORT}`);
});

async function checkIfFirstNumber(number) {
  if (number == 1) {
    return false;
  } else {
    for (let i = 2; i < number - 1; i++) {
      if (number % i === 0) {
        return false;
      }
    }
    return true;
  }
}

async function checkValuesInObject(obj) {
  const amount = Object.keys(obj);

  for (let i = 0; i < amount.length; i++) {
    let valueAmount = obj[Object.keys(obj)[i]];
    for (let j = 0; j < valueAmount.length; j++) {
      checkIfFirstNumber(valueAmount[j]).then((answer) => {
        console.log(`answer: ${answer}`);
        if (!answer) {
          checkNumber = false;
        }
      });
    }
  }
  checkNumber = true;
}

async function printPrime(number) {
  let numbers = "";
  for (let i = 2; i <= number; i++) {
    const check = await checkIfFirstNumber(i);
    if (check) {
      numbers += i + " ";
    }
  }
  return numbers;
}
