Issue
I’m trying to send a json to my nodeJs app through POST Method in body.
For that I’m using POSTMAN to create the request, with the proper consnt-type header and body JSON Rows. Tho the message back is "OK" in console the req.body is {} empty.
Would you have an idea what’s wrong in my code?
const bodyParser = require('body-parser');
const { Client } = require('pg');
const express = require('express');
const app = express();
// create application/json parser
const jsonParser = bodyParser.json()
// create application/x-www-form-urlencoded parser
const urlencodedParser = bodyParser.urlencoded({ extended: false })
const hostname = '127.0.0.1';
const port = 3000;
const dbSchema = 'public';
const client = new Client({
user: 'postgres',
host: 'localhost',
database: 'postgres',
password: '123123',
port: 5432,
});
client.connect();
/* =========== Some Initialize staff =============== */
// parse various different custom JSON types as JSON
app.use(bodyParser.json({ type: 'application/*+json' }))
app.use(bodyParser.urlencoded({
extended: true
}));
app.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
/* =========== FROM HERE =============== */
app.post('/post-test', urlencodedParser, (req, res) => {
console.log('Got body:', req.body);
res.sendStatus(200);
});
app.get('/',(req,res)=>{
res.status(200).send('Get Ready for something awesome!\n');
});
Solution
You should use app.use(bodyParser.json());, in your code const jsonParser = bodyParser.json() this is not used.
Update: Or you can apply jsonParser middleware directly to the post route:
app.post("/post-test", jsonParser, (req, res) => {
console.log("Got body:", req.body);
res.json({ ...req.body });
});
