Node(6) Accessing GET and POST data using http.ServerRequest

http.ServerRequest or simply request contains information from GET or POST

Get objects are in url

querystring.parse() turn the post data into an object

GET

GET example:

var http = require( 'http' );
var url = require( 'url' );
var util = require( 'util');
var querystring = require( 'querystring' );
var server = http.createServer( function( request, response ){

if( request.method === 'GET' ){
//parse the url
var parts = url.parse( request.url )

//write the GET details to response
response.writeHead( 200,  {'content-type': 'text/plain'});
response.write( 'path => ' + parts.path + '\n');
response.write( 'query => ' + parts.query + '\n');
response.write( 'foo => ' + querystring.parse( parts.query ).foo + '\n' );

response.end('Done!');
}
});

server.listen( 9000 );
console.log( 'server started' );

Without connect middleware

Post objects are in received in chunks,.

using data and end event

var http = require('http');
var querystring = require( 'querystring');
var util = require('util');
var form = require('fs').readFileSync('form.html');
var maxData = 2*1024*1024; //prevent mass post data

http.createServer( function(request, response){
if( request.method === 'POST' ){
//the post data is received by chunks
var postData = '';
request.on('data', function(chunk){
postData += chunk;
if( postData.length > maxData ){
pstData = '';
this.pause;//stop further data
response.writeHead(413);
response.end( 'Request too large');
}
}).on( 'end', function(){
if( !postData ){ response.end(); return; }//prevent empty post
var postDataObject = querystring.parse(postData);

//print postData to console
console.log('User Posted: \n', postData );

//response with postDataObject
response.end( 'You Posted: \n' + util.inspect( postDataObject));
});
}
if( request.method === 'GET' ){
response.writeHead(200, {
'Content-Type':'text/html'
});
response.end(form);
}
}).listen(9000);

Acess POST data using connect module 

request.body

var util = require( 'util');
var connect = require( 'connect');
var form = require( 'fs').readFileSync( 'form.html');

//connect.bodyParser allow connect to retrieve POST data
connect( connect.limit('64kb'), connect.bodyParser(),
function( request, response ){
if( request.method === 'POST'){
console.log( 'User posted:\n', request.body);
//request.body is the post object
response.end('You Posted:\n'+ util.inspect( request.body));
}
if( request.method === 'GET'){
response.writeHead(200, {
'Content-Type': 'text/html'
});
response.end(form);
}
}).listen( 9000 );
