如何使用nodejs filestream从NAPI (node-addon)接口读取文件并写入不同的文件

const fs = require('fs');
const addon = require('./addon'); // NAPI附加模块

function processFile(inputFilePath, outputFilePath) {
  const readStream = fs.createReadStream(inputFilePath);
  const writeStream = fs.createWriteStream(outputFilePath);

  readStream.on('data', (chunk) => {
    writeStream.write(chunk);
  });

  readStream.on('end', () => {
    writeStream.end();
    console.log('文件处理完成！');
  });
}

const inputFilePath = addon.getInputFilePath();
const outputFilePath = addon.getOutputFilePath();

processFile(inputFilePath, outputFilePath);
