使用nodejs获取数字总和并导入text / csv文件

Question

尝试在nodejs服务器上的文本文件（11,22,33,44）中对数字进行求和，我通过在url中输入一系列数字让它们如下图所示，但是我需要它能够输入/读取文件，如html中的输入标签，然后在浏览器中打印结果..这在节点中是否可行？甚至在url中键入文件路径/名称

s.js文件

const http = require('http')
const fs = require('fs')

let inFile = process.argv[2]
let outFile = process.argv[3]
console.log(inFile, outFile)

function sum (allNumbers) {
  return allNumbers.reduce( (s,x) => s += x)
}

const server = http.createServer(function(request, response) {
  response.writeHead(200, {"Content-Type": "text/html"})

  // INPUT PROCESSING
  response.write('<h1>Hello!</h1><p>You asked for <code>' + request.url + '</code></p>')
  console.log(request.url)
  // find characters after ?
  let dataStart = request.url.indexOf('?') + 1
  let dataString = request.url.slice(dataStart)
  // transform to array at the commas
  let arrayOfStrings = dataString.split(',')
  // convert to numbers
  let arrayOfNumbers = arrayOfStrings.map(s => Number(s))

  // CALCULATIONS
  let s = sum(arrayOfNumbers)

  // OUTPUT  PROCESSING
  response.write( arrayOfNumbers + "<p>");
  response.write( 'sum=' + s + '<p>')

  let result = {'data': arrayOfNumbers, 'sum': s}
  result = JSON.stringify(result)
  response.write(result)
  response.write('bye for now');
  response.end();
})

server.listen(8000);
