Posting data with Node.js

Recently i needed to post data using node.js, I was not trying to post a long string of data but rather parameters from a form. But the Node.js help page isn’t too helpful, it just say use request.write() to write data to the streamThis is the first interation i got.

var http=require('http');
var post=http.createClient(80,'localhost');
var request=post.request('POST',/test.php'.{'host':'localhost'});
request.write('test=10'); request.end();
request.on('response',function(response){
response.setEncoding('utf8');
reponse.on('data',function(chunk){ console.log(chunk); } });

test.php is a simple php script that prints out the parameter value.

I got nothing… nothing was printed out. What was wrong?

Using curl and Fiddler, i did a little investigating about what went wrong, what was missing was the Content-Length and the Content-Type which needs to be application/x-www-form-urlencoded.

Adding these 2 parameters to the script, results in

var http=require('http');
var post=http.createClient(80,'localhost');
var request=post.request('POST',/test.php'.{'host':'localhost','Content-Length':'7','Content-Type':'application/x-www-form-urlencoded'});
request.write('test=10');
request.end();
request.on('response',function(response){
response.setEncoding('utf8');
reponse.on('data',function(chunk){
console.log(chunk); } });

And yeah ! It works !
