NodeJS does not respond to CURL Request

Question

Im using NodeJS to perform som Queries to a MongoDB. I've set up the routing so when

     http://127.0.0.1:8888/GetAllCities

is called, a function name GetAllCities will run on the server and perform a MongoDB query and return the result. This works just fine when I try to visit the page directly in my browser. But when I try to make a CURL request the response is empty.

This is my jquery Ajaxcall

    function makeCall(urlToCall, method)
    {
        var params = "url=" + urlToCall + method;
        if(app === "PHP")
        {
            params += "&PHP=PHP";
        }

        $.ajax({
            type: "POST",
            url: "phpProxy.php",
            data: params,
            beforeSend: function()
            {
                document.write(app + ' -- Starting round ' + (i+1) + "<br />");
                document.write('URL: ' + params + "<br />");
                startTime = new Date().getTime();
            },
            success: function(data) {
                endTime = new Date().getTime();
                totalTime = endTime - startTime;
                if(totalTime > highest)
                {
                    highest = totalTime;
                }
                if(totalTime < lowest)
                {
                    lowest = totalTime;
                }
                var row = {};
                row.app = app;
                row.operation = method;
                row.totalTime = totalTime;
                row.run = i+1;
                row.date = new Date();
                document.write('\tTotal time: <strong>' + totalTime + 'ms</strong>' + "<br />");
                times.push(row);
                document.write(data + "<br />");
                document.write('Round done\n' + "<br />" + "<br />");
            },
            error: function(err) {
                console.log('Error');
                console.log(err);
            },
            complete: function()
            {
                i++;
                if(i < 50)
                {
                    makeCall(urlToCall, method);
                }
                else
                {
                    var sum = 0;
                    for(var j = 0; j < times.length; j++)
                    {
                        sum += parseInt(times[j].totalTime);
                    }
                    var avg = sum/times.length;
                    $('body').prepend('<h3>Slowest: ' + highest + 'ms</h3>');
                    $('body').prepend('<h3>Fastest: ' + lowest + 'ms</h3>');
                    $('body').prepend('<h3>Average: ' + avg + 'ms</h3>');

                    myApp.saveToDb(times);
                }
            }
        });
    } 

And this is my PHPPROXY FILE:

$method = $_SERVER['REQUEST_METHOD'];

$url = $_POST['url'];

$curl=curl_init();
curl_setopt($curl,CURLOPT_URL, $url);
curl_setopt($curl,CURLOPT_POST, TRUE);

if(isset($_POST['PHP']))
{
    $params = array('a' => 'php');
    curl_setopt($curl, CURLOPT_POSTFIELDS, $params);
}
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);

$result = curl_exec($curl);
curl_close($curl);

echo $result;

And this is my NODEJS requesthandlerfile.

var Db = require('mongodb').Db;
var Server = require('mongodb').Server;
var querystring = require("querystring");



function GetAllCities(response)
{
  console.log('Request recieved');
  var databaseUrl = "exjobb";
  var collections = ["cities"]
  var db = require("mongojs").connect(databaseUrl, collections);
  db.cities.find(function(err, cities) {
    response.writeHead(200, {"Content-Type": "application/json"});
    response.write(cities.length + " rows selected from the Database");
    response.end();
    db.close();
  });
}

function GetAllCitiesWhere(response)
{

  var databaseUrl = "exjobb";
  var collections = ["cities"]
  var db = require("mongojs").connect(databaseUrl, collections);
  db.cities.find({state: "AL"}, function(err, cities) {
  response.writeHead(200, {"Content-Type": "application/json"});
  response.write(cities.length + " rows selected from the Database");
  response.end();
  }); 
}

exports.start = start;
exports.GetAllCities = GetAllCities;
exports.GetAllCitiesWhere = GetAllCitiesWhere;

TLDR; My code works on a direct GET when visiting the page in a browser, but not when making ajax request, why? You can find all code here

This is solved as noted in the comments.

The problem was this line in my curl request.

curl_setopt($curl,CURLOPT_POST, TRUE);

I changed my PHP proxy to the following settings:

$method = $_SERVER['REQUEST_METHOD'];   
$url = $_POST['url'];   
$curl=curl_init();      
curl_setopt_array($curl, array(CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => $url,CURLOPT_USERAGENT => 'Josefs PHPPROXY'));
$result = curl_exec($curl);
curl_close($curl);
echo $result;
