Using AJAX Post and Node.js Express

I am trying to send data from my html for node.js Express using a post method.

Using this code on my html file:

function readfile() {
var data = {};
data.path = '/home/test/pgadmin.txt';
data.ext = '.txt';
console.log(data);
  $.ajax({
    url: '/read_file',
    type: 'POST',
    contentType: 'application/json',
    data: JSON.stringify(data),
    success: function(data) {
      console.log(data);
    }
  });
}

And this is the code that I'm using on server side.

var express = require('express')
var path = require('path')
var app = express()

app.post('/read_file', function(req, res) {
   console.log(req.data.path) //?
   console.log(req.data.ext) //?
   //I dont know how to get the values of my data: here

})

Is there some way to get those data values without using bodyparser?
