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?

Answer 1

<?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.

Answer 2

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.

Answer 3

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']));
