SyntaxError：JSON.parse 中的意外标记 t

Question

I want to use bodyParser on express. My posts.js file has

const express = require('express');
const router = express.Router();

const Post = require('../models/Post');

router.post('/', (req, res) => {
    console.log(req.body);
});

module.exports = router;

On app.js file, the code is like

const express = require('express');
const app = express();
const mongoose = require('mongoose');
const bodyParser = require('body-parser');

app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

const postsRoutes = require('./routes/posts');
// const usersRoutes = require('./routes/users');

app.use('/posts', postsRoutes);
// app.use('/users', usersRoutes);

Dependencies versions are

"body-parser": "^1.19.0",
"dotenv": "^8.2.0",
"express": "^4.17.1",
"mongoose": "^5.9.7",
"nodemon": "^2.0.3"

Server connected successfully but when I pass the data through postman on json mode, the terminal shows error like SyntaxError: Unexpected token t in JSON at position 3 at JSON.parse (<anonymous>)... I used the following code on app.js

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

because now express has buiild-in body-person function but output same here.

What can I do to solve this problem? I need help. Thanks in advance!

In JSON keys must be strings, try the following in the postman payload:

{
    "title": "Title here",
    "Description": "Description here..."
}

Instead of this:

{
    title: "Title here",
    Description: "Description here..."
}
