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 urlvar parts = url.parse( request.url )//write the GET details to responseresponse.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 datahttp.createServer( function(request, response){if( request.method === 'POST' ){//the post data is received by chunksvar postData = '';request.on('data', function(chunk){postData += chunk;if( postData.length > maxData ){pstData = '';this.pause;//stop further dataresponse.writeHead(413);response.end( 'Request too large');}}).on( 'end', function(){if( !postData ){ response.end(); return; }//prevent empty postvar postDataObject = querystring.parse(postData);//print postData to consoleconsole.log('User Posted: \n', postData );//response with postDataObjectresponse.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 dataconnect( connect.limit('64kb'), connect.bodyParser(),function( request, response ){if( request.method === 'POST'){console.log( 'User posted:\n', request.body);//request.body is the post objectresponse.end('You Posted:\n'+ util.inspect( request.body));}if( request.method === 'GET'){response.writeHead(200, {'Content-Type': 'text/html'});response.end(form);}}).listen( 9000 );
