req.body.data is undefined in expressjs

Question

I am new to nodejs and express js. I am trying to send a json object to my nodejs app using postman. PFB my app code

var express = require("express");

var bodyParser = require('body-parser');

var app   = express();

app.use(bodyParser.json());



app.post("/game",function(req,res){ 

      console.log(req.body);



      console.log(req.body.gameId);

//var body = req.body;

//game.addGame(req,res,body);



});





 app.listen(setting.port);

 console.log(`The app is listening to port ${setting.port}`);

I send the below json object using postman

{

    "gameID": 4,

    "gameLevel": 3,

    "gameImage": "/3wewe/wewrw",

    "gameName": "Game2",

    "waitTimeForWinny": 30,

    "totalTime": 31,

    "orderSequence": 1,

    "maxPoints": 10

}

Then I got the below output in the console.

{ gameID: 4,

  gameLevel: 3,

  gameImage: '/3wewe/wewrw',

  gameName: 'Game2',

  waitTimeForWinny: 30,

  totalTime: 31,

  orderSequence: 1,

  maxPoints: 10 }

undefined

The json object is coming in the req.body. But I am not able to extract the field from it by useing req.body.gameId

Please help me how to resolve this issue.

Answer 1

You are passing in the id property as gameID, but you are logging gameId (note the lowercase d)
