using postman 
req.body
contains key-value pairs of data submitted in request body. default, undefined, , populated when use body-parsing middleware such body-parser , multer.
the following example shows how use body-parsing middleware populate req.body.
var app = require('express')(); var bodyparser = require('body-parser'); var multer = require('multer'); // v1.0.5 var upload = multer(); // parsing multipart/form-data app.use(bodyparser.json()); // parsing application/json app.use(bodyparser.urlencoded({ extended: true })); // parsing application/x-www-form-urlencoded app.post('/profile', upload.array(), function (req, res, next) { console.log(req.body); res.json(req.body); }); please read link: http://expressjs.com/en/api.html#req.body
