将Python客户端连接到节点js服务器

我正在尝试将python客户端连接到Node JS服务器， 我想知道如何设置NodeJS服务器来为Python客户端提供服务

下面是我的Python客户端

import socket

TCP_IP = '127.0.0.1'
TCP_PORT = 8888
BUFFER_SIZE = 1024
MESSAGE = "Hello, World!"

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))
s.send(MESSAGE)
data = s.recv(BUFFER_SIZE)
s.close()

print "received data:", data

在node.js中使用http模块

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain; charset=UTF-8'});
  res.end('Hello World\n');
}).listen(8888, '127.0.0.1');
console.log('Server running at http://127.0.0.1:8888/');
