Nodejs之http的表单提交

 //提交表单数据
 var http=require('http');
 var querystring=require('querystring');
 
 var server=http.createServer(function (req,res) {
 //req.url不同则返回的页面不同
 if('/'==req.url){
  res.writeHead(200,{'Content-Type':'text/html'});
  res.write([
  '<form method="post" action="/url">',
  '<h1>My Form</h1>',
  '<fieldset>',
  '<label>Personal Information</label>',
  '<p>What is your name?</p>',
  '<input type="text" name="name">',
  '<button>submit</button>',
  '</form>'
  ].join(''));
  res.end();
 }else if('/url'==req.url&&req.method=='POST'){
  var reqBody='';
  req.on('data',function (data) {
  reqBody += data;
  });
  req.on('end',function () {//用于数据接收完成后再获取
  res.writeHead(200,{'Content-Type':'text/html'});
  res.write('you have sent a '+req.method+' request\n');
  res.write('<p>Content-Type:'+req.headers['content-type']+'</p>'
   +'<p>Data:your name is '+querystring.parse(reqBody).name+'</p>');
  res.end();
  })
 }else{
  res.writeHead(404);
  res.write('Not Found');
  res.end();
 }
 }).listen(3000,function () {
 console.log('server is listening 3000');
 });
