Node.js not reading HTML POST request

Question

My node.js script is receiving HTML POST request calls from the google Chrome extension Postman but it's not seeing the key-value pairs. Keeps giving me

TypeError: Cannot read property 'username' of undefined
   at app.get.params.QueueUrl (/home/ec2-user/Outfitr/Server/index.js:45:53)

Here's my code. Let me know if you need anything else

app.post('/bscreateuser', function(request, response) {
  process.stdout.write("Attempted to create a --- BBBSSSSS ---- user  |  ");
  process.stdout.write("request is " + request.url);
  process.stdout.write("username is " + request.body.username);
  process.stdout.write("Password is " + request.body.password);
  bscreateUser(request.query.username, request.body.password);
  response.send('Success' );
});

function bscreateUser(username, password) {
  messageBody = 'create_user("' + username + '","' + password + '")';
  queueUrl = DAO_QUEUE_URL;
  // sys.puts("--- going for BS ---");
  sendSQSMessage(JSON.stringify(messageBody), queueUrl);
}

SUGGESTION: Look at the actual HTTP content. There are many ways to do this, including Wireshark, Telerek Fiddler and the Chrome Developer Tools — FoggyDay
Shouldn't request.query.username be request.body.username? — mscdex

 bscreateUser(request.query.username, request.body.password);

Should be:

 bscreateUser(request.body.username, request.body.password);

A good way to avoid this in the future is:

var body = request.body;
var username = body.username;
var password = body.password

And then just use the var username and var password in your code, much less error prone and a little more readable!
