Node.js Question

Express + Postman, req.body is empty

I know this has been asked multiple times, but I have been looking around and still can't find an answer to my problem.

Here is my code, I make sure to use and configure body parser before defining the routes. I'm only using .json() with bodyParser because right now I'm only testing a POST function, but I've even tried with app.use(bodyParser.urlencoded({ extended: true }));

var express = require('express'),
bodyParser = require('body-parser'),
app = express();

app.use(bodyParser.json());
app.set('port', (process.env.PORT || 5000));

app.listen(app.get('port'), function() {
console.log("Node app is running at localhost:" + app.get('port'))
});

app.post('/itemSearch', function(req, res) {
//var Keywords = req.body.Keywords;
console.log("Yoooooo");
console.log(req.headers);
console.log(req.body);
res.status(200).send("yay");
});


Here is how I use Postman to test this route.
enter image description here

and here is the response I receive

Node app is running at localhost:5000
Yoooooo
{ host: 'localhost:5000',
connection: 'keep-alive',
'content-length': '146',
'cache-control': 'no-cache',
origin: 'chrome-extension://fhbjgbiflinjbdggehcddcbncdddomop',
'content-type': 'multipart/form-data; boundary=----WebKitFormBoundarynJtRFnukjOQDaHgU',
'user-agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36',
'postman-token': '984b101b-7780-5d6e-5a24-ad2c89b492fc',
accept: '*/*',
'accept-encoding': 'gzip, deflate',
'accept-language': 'en-GB,en-US;q=0.8,en;q=0.6' }
{}


At this point I would really appreciate any help. Thanks.

Answer

AFAIK you need to use the Body-Parser : https://github.com/expressjs/body-parser

bodyParser = require('body-parser').json();
app.post('/itemSearch', bodyParser, function(req, res) {
  //var Keywords = req.body.Keywords;
  console.log("Yoooooo");
  console.log(req.headers);
  console.log(req.body);
  res.status(200).send("yay");
});

Then try with PostMan setting the body as raw json:

{
  "test": "yay"
}
