Send Data from Drupal to node.js

Question

I'm a newbie with drupal.

I was trying to send data from drupal to node.js function and save the data from node into mongo.

I wrote a function in php

function sample_working_submit($form, &$form_state) { //Function to connect with node and save into Mongo using node
  $Name = check_plain($form_state['values']['Name']);
  $Age = check_plain($form_state['values']['Age']);
  $request_url = "http://10.20.5.112:3001/save/$Name/$Age ";
  $response = drupal_http_request($request_url);
}

This is working as long as there is no 'space' between the names(input). How can save the input with spaces.Why does this issue came?

How can i rewrite the function as post?

<?php
$url = http://localhost:8080/myservlet;

$data = array (
    'name' => check_plain($form_state['values']['Name']),
    'age' => check_plain($form_state['values']['Age'])
    );

$response = drupal_http_request($url, $headers, 'POST', json_encode($data));
?>

This would POST data to URL. Note that you need to change logic in server side as well to receive POST data instead of GET data.

I was trying this but I'm getting error Warning: http_build_query(): Parameter 1 expected to be Array or Object. I included $headers = array(); – Okky Jun 04 '13 at 04:20
$options = array( 'method' => 'POST', 'data' => $jsonData, 'timeout' => 15, 'headers' => array('Content-Type' => 'application/x-www-form-urlencoded'), ); $result = drupal_http_request($request_url, $options); – Okky Jun 04 '13 at 04:38

If the space between the names is the issue, try using urlencode().

The code will be something like:

$Name = urlencode(check_plain($form_state['values']['Name']));

But in this case its saved in the database with a '+'. Is there any way to avoid that? – Okky Jun 03 '13 at 11:54
Where does the `+` come from ?! – Muhammad Reda Jun 03 '13 at 11:55
@MuhammadReda Node.js application logic most probably. Sreekesh, you're going to need to alter this on the Node.js side of things. – Clive Jun 03 '13 at 11:57
When I input name as 'sreekesh okky' its send to the node as 'sreekesh+okky' – Okky Jun 03 '13 at 11:57
@SreekeshOkky Perhaps then you should splitup the parameters, or stil better use JSON, instead of relying on GET. – GoodSp33d Jun 03 '13 at 12:02
@2-Stroker I tried that. But i got confused in how to send JSON. Can you help me out with a sample. – Okky Jun 03 '13 at 12:17

For POST requests I use SimpleBrowser instead of drupal_http_request(). It's easy to use and you'll be able to pass strings in any form.
