Posting data to an endpoint which is working fine when I select raw and send json.
I am not receiving anything when I select form-data. I have already defined them in my server.js.
server.js config:
const express = require("express");
const bodyParser = require("body-parser");
const cors = require("cors");
const app = express();
var corsOptions = {
origin: "http://localhost:8081"
};
app.use(cors(corsOptions));
app.use(express.static('app/uploaded'));
// parse requests of content-type - application/json
app.use(bodyParser.json());
// parse requests of content-type - application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: true }));
Here is the postman request.
hi for parsing different form of data you have to add different middleware to access it
here is the code for parsing response:
var express = require('express');
var bodyParser = require('body-parser');
var multer = require('multer');
var upload = multer();
var app = express();
// for parsing application/json
app.use(bodyParser.json());
// for parsing application/xwww-
app.use(bodyParser.urlencoded({ extended: true }));
//form-urlencoded
// for parsing multipart/form-data
app.use(upload.array());
refer this doc for more detail documentation of body-parser with form data
let me know if its help

I am having this problem in express.js I have been searching how to solve it but stilln nothing. I'm sending a base64 in the body of a pdf of about 130kb.
This is my index and. I added the limit in the app.use(express.urlencoded())
const express = require('express');
const db = require('./config/config');
const adminDb = require('./config/config');
const cors = require('cors')
const app = express();
app.use(cors());
app.options('*', cors()); // enable pre-flight
app.use(express.json());
//added this ↓↓↓↓↓↓↓↓
app.use(express.json({limit: '2500mb'}));
app.use(express.urlencoded({limit: '2500mb',extended: false, parameterLimit: 100000}));
I got this error "Cannot GET /api/data"
it s working good on my local host , but when I upload it to server it show me this error,
this is a simple code for testing that also show me the same .
my index page
const express = require('express');
const bodyparser = require('body-parser');
const mysql = require('mysql');
const port = 4000;
const route = require('route');
const data = require('./routes/data.js');
const app = express();
app.use(bodyparser.json());
// parse application/x-www-form-urlencoded
app.use(bodyparser.urlencoded({ extended: false }));
// parse the raw data
app.use(bodyparser.raw());
// parse text
app.use(bodyparser.text());
app.use('/data', data);
app.listen(port, () => {
console.log("working");
});
/routes/data.js file
const express = require('express');
const router = express.Router();
const add = require('../classes/insert');
const bodyparser = require('body-parser');
var con = require('../Modules/connection');
const app = express();
app.use(bodyparser.json());
// parse application/x-www-form-urlencoded
app.use(bodyparser.urlencoded({ extended: false }));
// parse the raw data
app.use(bodyparser.raw());
// parse text
app.use(bodyparser.text());
app.get("/",(req, res)=>{
res.send("hello");
});
module.exports = router;
app.use('/data', data)
This will only work on /data route. If you want this work on /api/data, use the following snippet.
app.use('/api/data', data)
this error may be comming because of the file path. Try using __dirname in spite of ./ and also check your file structure.
Hope this works.
When do I use bodyparser in my code?
const express = require('express');
const bodyparser = require('body-parser');
const app = express();
app.set('views',__dirname+'/public/pages/');
app.set('view engine','twig');
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
// parse application/json
app.use(bodyParser.json())
app.get('/',(req, res)=>{
res.render('index',{title:"create user"})
})
app.post('/',(req, res)=>{
console.log(req.body.username);
})
app.listen(8000, ()=>console.log('server is running at:http://localhost:8000'));
when I run this code:Errorenter image description here
you have const bodyparser = require('body-parser'); in lowercase ,then you use it with camelCase
bodyParser.urlencoded({ extended: false })
There is a spelling mistake just change bodyparser to bodyParser in second line of your code.
When do i use bodyparser in my code ?
npm page for the module says, "Node.js body parsing middleware.
Parse incoming request bodies in a middleware before your handlers, available under the req.body property."

Question
I'm trying build a Node.js API, when write my server.js file, my code looks like this:
var express = require('express');
var express = require('body-parser');
var app = express();
app.use(bodyParser.json());
app.get('/api/posts', function(req,res) {
res.json([
{
username: 'oscar',
body: 'hello'
}
])
})
app.listen(3000, function() {
console.log('Server Listening on', 3000)
})
However, in the command prompt I am getting this error:
body-parser deprecated bodyParser: use individual json.urlencoded
middlewares server.js:4:11
body-parser deprecated undefined extended: provide extended option
node_modules\body-parser\index.js:85:29
I tried changing this to :
app.use(bodyParser.urlencoded({ extended: true }));
and
app.use(bodyParser.urlencoded({ extended: false }))
like other posts suggest, but it still gives the same error. Not sure what to do now! Please help.
Thanks!
var app = express();
// configure body-parser
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());
I had similar deprecated warning. Here's my original code:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
Adding {extended: true} fixed the warning for me. Here's changed code:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
Unless you have a typo, change:
var express = require('body-parser');
var app = express();
app.use(bodyParser.json());
to:
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser());
Do have a look at what the request and response objects do here
You don't actually need the line app.use(bodyParser.urlencoded({extended: true}));
I've got it to work with the following code:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.json());
As log as you have app.user(bodyParser.json()); you shouldn't get the error.
You don't need body-parser module any more with current express.js versions (≥ 4.16).
Instead, use the json parser already included in express:
app.use(express.json())
Source: https://expressjs.com/en/changelog/4x.html#4.16.0
Don't use body-parser
In new versions of express, body parsing is now builtin. So, you can simply use
app.use(express.json()) //For JSON requests
app.use(express.urlencoded({extended: true}));
from directly express
You can uninstall body-parser using npm uninstall body-parser
Then you can simply get the POST content from req.body
app.post("/yourpath", (req, res)=>{
var postData = req.body;
//Or for string JSON body, you can use this
var postData = JSON.parse(req.body);
});
The relevant part of my app.js is as follows
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
var routes = require('./config/routes);
app.use('/', routes);
My route file is:
var express = require('express');
var router = express.Router();
var upgradesController = require('../../app/controllers/upgrades.server.controller');
// This should receive POST requests
router.post('/api/upgrades/device', upgradesController.create);
module.exports = router;
And finally my controller is
exports.create = function(req, res) {
res.send(req.body);
}
But this sends nothing. It's always an empty JSON value. I'm using PostMan for testing:
What is happening?
You're sending form-data, switch to x-www-form-urlencoded instead. You can also send "raw", and input valid JSON.
