下面模拟的是网页登陆的过程，当我们请求一个链接时，，会获得一个表单，然后再表单中填入相应的值，然后提交登陆。
var http = require('http');var querystring = require('querystring');http.createServer(function (request, response) {var responseString = '';response.writeHead(200, {'content-type': 'text/html'}); // 如果是get请求var postData = "";if (request.method == "GET") {responseString = '<!doctype html><html lang="en">\&;head><meta charset="UTF-8" />\&;title>Document</title>\&;/head>\&;body>\&;form action="/" method="post">\&;input type="text" name="name" value="xulidong" />\&;input type="text" name="password" value="123456" />\&;input type="text" name="code" value="abc123" />\&;input type="submit" value="submit" />\&;/form>\&;/body>\&;/html>';response.write(responseString);response.end();} else if (request.method == "POST") {request.setEncoding("utf8");request.addListener("data", function (postDataChunk) {postData += postDataChunk;});request.addListener("end", function () {var objectPostData = querystring.parse(postData);for (var i in objectPostData) {responseString += i + " => " + objectPostData[i] + "<br>";}response.write(responseString);response.end();});}}).listen(8080, '192.168.33.98');打开浏览器输入：:8080/，192.168.33.98是我电脑的IP，会得到如图的网页：
这个网页是我们在处理GET请求的代码中生成的，默认都填入的相应的值，我们可以修改或者直接点击submit按钮提交，然后得到如下的结果：
