我已经用express和node.js创建了2个服务器，现在我想在同一个端口localhost：8000上用不同的端点运行这两个服务器。如何做到这一点？
附加服务器代码以供参考：-

服务器1：-

const express = require("express");
const cors = require("cors");
const app = express();
const axios = require('axios');

app.use(cors());
process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0;
const PORT = 8000;

app.get("/WeatherForcast", function (req, res) {
  axios.get('https://localhost:7173/WeatherForecast')
  .then(response => {
    res.status(200).json({ success: true, data: response.data});
  })
  .catch(error => {
    console.log(error);
  });
});

app.listen(PORT, function () {
  console.log(`Server is running on ${PORT}`);
});

服务器2：-

const express = require("express");
const cors = require("cors");
const app = express();
const axios = require('axios');

app.use(cors());
process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0;
const PORT = 8000;

app.get("/UserData", function (req, res) {
  axios.get('https://localhost:7173/UserData')
  .then(response => {
    res.status(200).json({ success: true, data: response.data});
  })
  .catch(error => {
    console.log(error);
  });
});

app.listen(PORT, function () {
  console.log(`Server is running on ${PORT}`);
});

当前运行时，一台服务器运行，另一台服务器显示端口8000已在使用中的错误。
