How to get post parameters in Node.js

I am not able to get the post parameters in my node js ,when I put console it says undefined but when I post parameters from postman it is working.Can anyone suggest help, please?

exports.login = function( req, res ) {
console.log(req.body)
  var query = 'select * from profile where email = ? and password = ?'; 
 connection.query(query,[req.body.email,req.body.password],function(error,result,rows,fields){
    if(!!error){console.log(error)
      console.log('fail');
    }else{
      console.log(result);
      res.send(result);
    }
  // }

  });}

My Express code,

    var express = require('express')
  , cors = require('cors')
  , app = express(); 

var admin = require('../controller/user'); 
 router.post('/login',cors(), admin.login);

Always put body-parser before all route. Like this

  var app=express();
  app.use(bodyParser.json());
  app.use(bodyParser.urlencoded({ extended: true }));

Other wise always get undefined body value if you use it before any route since body not parsed yet.

You forgot to use bodyParser. First install it using command

npm install body-parser --save

Then add the following to your app

var bodyParser = require('body-parser');
app.use(bodyParser.json()); // support json encoded bodies
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies

After that you can use req.body
