I have the following App.js:
var express = require('express'),
app = express(),
engines = require('consolidate'),
MongoClient = require('mongodb').MongoClient,
assert = require('assert'),
bodyParser = require('body-parser')
app.engine('html', engines.nunjucks);
app.set('view engine', 'html');
app.set('views', __dirname + '/views');
app.use(bodyParser.urlencoded({ extended : true }));
// app.use(bodyParser.urlencoded());
// app.use(bodyParser.json());
app.post('/insert_movie', function (req, res) {
var movieName = req.body.movie_name;
console.log(movieName);
});
// No route matching:
app.use(function (req, res) {
res.sendStatus(404);
});
var server = app.listen(3000, function () {
var port = server.address().port;
console.log('Express server listening on port %s.', port);
});
My html page:
<h1> Add new movies</h1>
<form action="/insert_movie" method="POST">
<input type="text" id="movie_name">
<input type="text" id="movie_year">
<input type="text" id="movie_imdb">
<input type="submit" value="Submit" />
</form>
When I enter values into the text boxes and press submit, my post method is hit ('/insert_movie'). However movieName is undefined not only that but req.body is {}
Can someone explain to me what I'm doing wrong here as I've gone through many solutions on this website however they're all pointing the body parser being incorrectly setup, I've tried the following:
app.use(bodyParser.urlencoded({ extended : true }));
app.use(bodyParser.urlencoded());
app.use(bodyParser.json());
Neither of these fix my issue.
You need to add name attribute to the input elements. That's one of the things your body-parser library needs to parse the form.
<h1> Add new movies</h1>
<form action="/insert_movie" method="POST">
<input type="text" name="movie-name" id="movie_name">
<input type="text" name="movie-year" id="movie_year">
<input type="text" name="movie-url" id="movie_imdb">
<input type="submit" value="Submit" />
</form>
try to use this
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({
limit: '500mb',
extended: true,
parameterLimit: 50000
}));
app.use(expressValidator());
app.use(bodyParser.json());
use multer middle ware for req.body
var app = require('express')();
var multer = require('multer);
var upload = multer().any();
//multer().any() upload both array and file
//add the multer middle ware in your router
app.post('/insert_movie',upload, function (req, res) {
var movieName = req.body.movie_name;
console.log(req.body);
console.log(movieName);
});
you can see the official npm blog

edit:guys I'm genually new to all of this. here's the html form I used. should i update this question with something else?
<form action="/pesquisar" method="post">
<input type="text" id="cO">
<input type="text" id="cD">
<input type="submit">
</form>
I'm currently trying to design a simple browser app utilizing express. console.log(req.body) comes back {} and i cant find the solution, been here for the best part of the day lol
Here's my app
var express = require('express');
var path = require('path');
var logger = require('morgan');
var bodyParser = require('body-parser');
var app = express();
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(express.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.get('/', function(req, res){
console.log(req.body);
res.render('index', {
infoVoos: 'acesso_inicial'
});
});
app.post('/pesquisar', function(req,res){
console.log("");
console.log("");
console.log(req.body);
res.send('ok');
});
app.listen(3000);
console.log('############');
console.log('Server on');
console.log('');
module.exports = app;
I changed the parameter of the input tag from "id" to "name" and it's working fine now.
original
<form action="/pesquisar" method="post">
<input type="text" id="cO">
<input type="text" id="cD">
<input type="submit">
</form>
new
<form action="/pesquisar" method="post">
<input type="text" name="cO">
<input type="text" name="cD">
<input type="submit">
</form>
thankx guys
I have made super simple code for the sole purpose of receiving data from the client.
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
app.use(bodyParser.json());
var PORT = 80;
app.get('/',function(req,res){
res.send('<form action="/" method="post"> <input type="text"name="firstname" value="Mickey"><input type="submit" value="Submit"> </form>');
});
app.post('/', function (req, res) {
console.log(req.body.firstname);
res.send('POST request to the homepage');
});
app.listen(PORT, () => console.log("Listening on port "+PORT));
That is it. but when I run it it says that req.body.firstname is undefined.
What am I doing wrong?
To parse form data, you'll have to use the bodyParser.urlencoded middleware.
Add the following to your code, before you handle the POST request:
app.use(bodyParser.urlencoded({ extended: false }));
I am new to nodejs and express in general. I am trying to get a POST value from a html page using body-parser. I tried following several suggestions in SO but unable to make it work for me.
Here is the code. Any pointers will be highly appreciated. Thanks in advance.
Server.js
var express = require('express');
var mongoose = require('mongoose');
var bodyParser = require('body-parser');
var Subscribe = require('./models/subscribe');
mongoose.connect('CREDENTIALS');
var app = express();
app.use(bodyParser.json(), bodyParser.urlencoded({ extended: false }));
var port = 3000;
var router = express.Router();
router.get('/', function(req, res) {
res.json({ message: 'Test...' });
});
var subscribeRoute = router.route('/subscribe');
subscribeRoute.post(function(req, res) {
var subscribe = new Subscribe();
subscribe.email = req.body.email_notify;
console.log(subscribe);
subscribe.save(function(err) {
if (err)
res.status(500).send(err);
res.status(200);
});
});
app.use('/api', router);
app.listen(port);
index.html
<form action="http://localhost:3000/api/subscribe/" method="POST" enctype="application/json">
<input type="text" onfocus="if (this.value=='E-mail Address') this.value = ''" onblur="if (this.value=='') this.value = 'E-mail Address'" value="E-mail Address" id="email_notify" name="email_notify" />
<button id="notify_me" ontouchstart="">Notify Me!</button><br/>
</form>
Thanks

change this
app.use(bodyParser.json(), bodyParser.urlencoded({ extended: false }));
To this
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
Make <input type='submit'> instead of the <button> and remove enctype form the form.
Also in Chrome open developer tools, network tab and check that the request is sent to your server at all
I am trying to get data from a form using express js.But i will get an undefined error in my console.
here is my html
<form action="/login" method="post">
<label>Username</label>
<input type="text" name="username" value=""><br><br>
<label>Password</label>
<input type="password" name="password" value=""><br><br>
<input type="submit" name="" value="Login">
</form>
index.js
var app = require('express')();
var url = require('url');
var server = require('http').Server(app);
var io = require('socket.io')(server);
var mongoose=require('mongoose');
var path = require('path');
var express = require('express');
var bodyParser = require('body-parser');
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
// for login
app.post('/login',function(req,res){
console.log("server"+req.body.username+req.body.password);
});
I will get undefined error in my console,also i have installed body-parser in my application.
I'm not having issue with this code:
var app = require('express')();
var server = require('http').Server(app);
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.post('/login',function(req,res){
console.log(req.body);
console.log("server"+req.body.username+req.body.password);
});
var server = app.listen(3000);
And testing with:
curl 'http://127.0.0.1:3000/login' --data 'username=zetg&password=zetgze'
I don't know what is wrong with your code, but try going slowly step by step, and including your functionalities one by one.
I want to receive data from client, so I use express 4 and middleware body-parser.
But I input url:localhost:5555/book, page show the message: Name: undefined,
and I input url:localhost:5555/book/form.html, page show the message Cannot POST /book/form.html.
Here is my code.
form.html
<form action='./book' method='post'>
<input type='text' name='name' value='fred'>
<input type='text' name='tel' value='0926xxx572'>
<input type='submit' value='Submit'>
</form>
server.js
var express = require('express');
var bodyParser = require('body-parser')
var app = express();
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(bodyParser.json());
app.post('/book', function(req,res){
console.log(req.body.name);
console.log(req.body.tel);
res.send('Name: '+req.body.name);
res.send('country: '+req.body.tel);
res.end();
});
app.listen(5555);
From what I see, you're doing a app.post on the route /book so express expects a POST request.
But when you go to the url http://localhost:5555/book you are doing a GET request, thus the error.
There should be one page (a GET request therefore a app.get) for displaying the form and one page for accepting post requests.
I don't use html ，I replaced by jade.
And I use app.route().
form.jade
form(action='./book' method='post')
input(type='text' name='name' value='fred')
input(type='text' name='tel' value='0926xxx572')
input(type='submit' value='Submit')
server.js
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.set('views', './views');
app.set('view engine', 'jade');
app.engine('jade', require('jade').__express);
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(bodyParser.json());
app.route('/book')
.get(function(req, res) {
//res.send('Get a random book');
res.render('form');
})
.post(function(req, res) {
res.send('Name: '+req.body.name +'<br>'+ 'tel: '+req.body.tel);
})
app.listen(5555);
