Converting ajax to node.js

Question

I've learnt dealing with ajax calls to exchange information from the server to the browser but now I'm having big troubles converting my code to a server-side node compatible JS using http requests. I've read different tutorials but I just can't adapt them to my code. My simple JS / jQuery function is this:

function ajaxCall(data, php, callback) {
    ax = $.ajax({
        type: "POST",
        data: data,
        url: php,
        success: function (raw_data) {
            f = $.parseJSON(raw_data);
            callback(f);
        },
    });
}

And I need to convert it to a pure JS version with http requests to use with node.js. Thanks for any help.

EDIT: I tried and tried, but without success. Here is the code I used, I just get lots of meaningless words on my console.log, perhaps you can correct it:

Version 1

var data = {"action": "update", "tN": 2155};
var request = require("request");

request.post({
    url: 'http://example.com/PHP.php',
    data: data,
    }, function(error, response, body){
    console.log(body);
    }
);

Version 2

var request = require("request");
var options = {
    method: 'POST',
    uri: 'http://example.com/PHP.php',
    data: {"action": "update", "tN": 2155},
};    
request(options, function(error, response, body) {
    if(error){
        console.log(error);
    }else{
        console.log(response);
    }
});

Answer 1

Use request.js

Example:

var request = require('request');
request('http://www.google.com', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body) // Show the HTML for the Google homepage.
  }
})
