如何使用node js express将变量传递给函数[不同的文件

// data.js
const myVariable = 'Hello, World!';

module.exports = myVariable;

// app.js
const express = require('express');
const myVariable = require('./data.js');

const app = express();

app.get('/', (req, res) => {
  myFunction(myVariable);
  res.send('Variable passed to function successfully.');
});

function myFunction(variable) {
  console.log(variable);
  // 这里可以对变量进行处理或执行其他操作
}

app.listen(3000, () => {
  console.log('Server running on port 3000');
});
