Node.js实现一个HTTP服务器的方法示例

if (request.url === '/') {
 fs.readFile('./login.html', function (err, data) {
  if (!err) {
   response.writeHead(200, { "Content-Type": "text/html;charset=UTF-8" });
   response.end(data)
  } else {
   throw err;
  }
 });
}

if (!request.headers.cookie) {
 response.writeHead(301, { 'Location': '/' })
 response.end()
}

window.location.href = '/index'

let input = {
 name: document.querySelector('.input').value
}
let request = new XMLHttpRequest(); // 新建XMLHttpRequest对象
request.open('POST', '/login', true)
request.send(JSON.stringify(input))

let input = {
 name: document.querySelector('.input').value
}
let request = new XMLHttpRequest(); // 新建XMLHttpRequest对象
request.open('POST', '/login', true)
request.send(JSON.stringify(input))

if (request.url === '/getHead') {
 response.writeHead(200);
 response.end()
}
