jquery - Get data from AJAX request in NodeJS and store in DB -

i have problem getting data client side in nodejs.

on client side i've prepared json data can see in codepen

on server side i'm trying these data client:

var express = require('express'); var mysql = require('mysql');  var app = express();  app.use('/', express.static('../client/app')); app.use('/bower_components', express.static('../client/bower_components/'));  var server = require('http').createserver(app);  var bodyparser = require('body-parser'); app.jsonparser = bodyparser.json(); app.urlencodedparser = bodyparser.urlencoded({ extended: true });  //mysql connection setup var connection = mysql.createconnection({     host : "localhost",     port: "3306",     user : "root",     password : "",     database : "db",     multiplestatements: true });  app.get("/cities", function(req, res) {      console.log(res.body); //i'm getting nothing      var data= {         city: req.body.city,         country: req.body.country     };      var query = connection.query('insert table set ?', data, function(err, res) {         if (err) {             console.log(err);         } else {             console.log('success');             }     });     console.log(res);  });  server.listen(3000, function () {     'use strict'; }); 

what i'm doing wrong? there way debug nodejs in st? thanks.

please try req.params.city fetch input data. works in project. however, req.body use getting data sent through post method.

app.get - use req.params app.post - use req.body
