Twilio statusCallback implementation running into trouble - node.js

Question

I am a beginner to Twilio. I understand that I can get the status of the SMS send by having a statusCallback, so that the POST will happen to the callbackurl with the status of the message. But I am having troubles in creating that particular POST endpoint.
Here is what I have :
// Twilio API CALL
client.sendMessage({
to:userId,
from: metadata.myTwilioNumber,
body: message,
StatusCallback:'POST URL'
}, function(err, responseData) {
if (!err) {
} else {
logger.info(err);
}
My POST endpoint is a simple node js (request, response) endpoint.
var server = http.createServer ( function(request,response){
response.writeHead(200,{"Content-Type":"text\plain"});
if(request.method == "GET")
{
response.end("received GET request.")
}
else if(request.method == "POST")
{
console.log(request.CallStatus);
console.log(response);
console.log('receivedRequest');
response.end("received POST request.");
}
else
{
response.end("Undefined request .");
}
});
server.listen(4445);
Can someone help me in getting the status and messageID of the response? Currently, the POST is getting invoked but i am unable to get the message details and status.

Twilio developer evangelist here.
You are using the basic Node.js standard library http module which is going to make it a lot of work to extract the information from the POST request. Can I recommend you try something like express with body-parser instead.
You can do so by installing the two modules with npm:
npm install express body-parser
Then you can rewrite your incoming message application like this:
const express = require('express');
const bodyParser = require('body-parser');
const app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.post('/', (req, res) => {
console.log(req.body.CallStatus);
res.sendStatus(200);
});
app.listen(4445, () => {
console.log('Application running on localhost:4445');
});
All the parameters that Twilio sends will be available on the req.body object.
