【NodeJS】用NodeJs写一个最简单的http服务器

const http = require('http')

http.createServer(function(req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'})
  res.end('Hello World\n');
}).listen(3000)

console.log('Server Running at http://localhost:3000')

下面是第二种写法：

const http = require('http')

const server = http.createServer()

server.on('request', function(req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'})
  res.end('Hello World\n');
})

server.listen(3000)

console.log('Server Running at http://localhost:3000')
