In the server side:
var express = require('express');
var app = express();
app.listen(8000);
app.configure(function(){
app.use(express.methodOverride());
});
app.put('/update', function (req, res) {
res.send("update!");
})
I want test the put method
in the client side:
<form action="/update">
<input type="hidden" name="_method" value="put"/>
<input type="submit" value="submit">
</form>
but the result is
Cannot GET /update?_method=put
so, what's wrong with my code?
You need to include the bodyParser middleware too:
app.use(express.bodyParser());
app.use(express.methodOverride());
You have a typo: /upadte should be /update.
edit: try using method="post" in your form tag.

How do I post a value which is on the client-side and get it on the server-side.
example:
<form action="/myform" method="POST">
<input type="text" name="mytext" required />
<input type="submit" value="Submit" />
</form>
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.get('/myform', function(req, res){
var myText = req.body.mytext; //mytext is the name of your input box
res.send('Your Text:' +myText);
});
app.listen(3000)
<form action="http://127.0.0.1:3000/myform" method="post">
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true }));
//app.use(express.bodyParser());
app.post('/myform', function(req, res) {
var myText = req.body.mytext; //mytext is the name of your input box
res.send('Your Text:' +myText);
});
Your code seems to be fine, apart from wrong method name. In HTML form you have mentioned POST method but at server you are listening to GET method. So just change, app.get('/myform', to app.post('/myform',.
It should work.
Im using express, node, bodyParser to pull information from a contact form and post it to the terminal. When I run the code and access my demo site through LocalHost:3000, upon submitting, my input items are not showing up in the terminal.
I've tried changing the form attributes action="send" action="/send" action="/"
const express = require('express');
const path = require('path');
const bodyParser = require('body-parser');
const exphbs = require('express-handlebars');
const nodemailer = require('nodemailer');
const app = express();
// View engine setup
app.engine('handlebars', exphbs());
app.set('view engine', 'handlebars');
// Static folder
app.use('/public', express.static(path.join(__dirname, 'public')));
/ Body Parser Middleware
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.get('/', (req, res) => {
res.render('contact', { layout: false });
});
app.post('/send', (req, res) => {
console.log(res.body);
});
//Form HTML code
<form action="send" method="POST">
<input name="name" type="text" id="name" placeholder="NAME: First & Last">
<input name="email" type="text" id="email" placeholder="EMAIL:">
<textarea name="text" id="text" cols="30" rows="10" placeholder="QUESTION OR INQUIRY:"></textarea>
<br>
<button type="submit">Submit</button>
</form>
Have you tried console logging the req instead of the res for the app.post?
If you are doing console.log(req.body) then this should output a long json object. If this is not happening, then you are not hitting the url.
const express = require('express');
const path = require('path');
const bodyParser = require('body-parser');
const exphbs = require('express-handlebars');
const nodemailer = require('nodemailer');
const app = express();
// View engine setup
app.engine('handlebars', exphbs());
app.set('view engine', 'handlebars');
// Static folder
app.use('/public', express.static(path.join(__dirname, 'public')));
// Body Parser Middleware
app.use(bodyParser.urlencoded({extended:false}));
app.use(bodyParser.json());
app.get('/', (req, res) => {
res.render('contact', { layout: false });
});
app.post('/send', (req, res) => {
console.log(res.body);
});
The problem is in your html code. I have made some changes, Try this.
//Form HTML code
<form action="http://localhost:9000/send" method="POST">
<input name="name" type="text" id="name" placeholder="NAME: First & Last">
<input name="email" type="text" id="email" placeholder="EMAIL:">
<textarea name="text" id="text" cols="30" rows="10" placeholder="QUESTION OR INQUIRY:"></textarea>
<br>
<button type="submit">Submit</button>
</form>
I am using:
var express = require("express"),
app = express(),
bodyParser = require("body-parser");
with:
app.use(bodyParser.urlencoded({extended: true}));
Form:
<form action="/[route]" method="GET">
<input type="text" name="[name]">
<input type="submit" value="Show Results">
</form>
Route:
app.get("/[route]", function(req, res){
console.log(req.body.[name]);
});
The issue I am having is when I try to access the req.body.[name of input] it is 'undefined'
It's like the body parser is not working and I am not sure why.
I have an express app that takes basic user input data. All of my get routes work fine but when submit a post request to the server I get a 404 on the url I'm posting to even though I have this page in my views folder.
app.js:
var express = require('express');
var path = require('path');
var consolidate = require('consolidate');
var bodyParser = require('body-parser');
var database = require('./database/database');
var Patient = require('./models/models').Patient;
var morgan = require('morgan');
var routes = require('./routes');
var app = express();
app.engine('html', consolidate.nunjucks);
app.set('view engine', 'html');
app.set('views', './views');
app.use(morgan('dev'));
//app.use(app.router);
app.use(routes);
app.use(bodyParser.urlencoded({ extended: false }));
app.listen(3055);
module.exports = app;
routes/index.js:
const express = require('express');
var bodyParser = require('body-parser');
var Patient = require('../models/models').Patient;
const router = express.Router();
router.get('/', function(req, res, next){
res.render('index.html');
});
router.post('/addsubject', function(req, res, next){
Patient.create(req.body).then(function(patient){
res.redirect('/profile');
}).catch(function(err){
if(error.name === "SequelizeValidationError"){
} else {
return next(err);
}
}).catch(function(error){
res.send(500, error);
});
});
router.get('/profile', function(req, res, next){
res.render('./profile.html');
});
router.get('/addsubject', function(req, res, next){
// .... do something here ..
});
module.exports = router;
I have the <form action="/addsubject" method="post"> in my index.html file.
index.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>dabl Demographic</title>
<body>
<h2>Add Subject</h2>
<form action="/addsubject" method="post">
<label for="fname">First Name: </label>
<input type="text" name="fname" id="fname">
<br>
<label for="sname">Second Name: </label>
<input type="text" name="sname" id="sname">
<br>
<label for="dob">dob: </label>
<input type="text" name="dob" id="dob">
<br>
<label for="laterality">Laterality: </label>
<input type="text" name="laterality" id="laterality">
<br>
<button>Submit</button>
</form>
</body>
</html>
You pass wrong function (error handling function) to the POST route.
Just remove first "err" param from the function like this:
router.post('/addsubject', function(req, res, next){
Use body-parser middleware before app.router
...
app.use(bodyParser.urlencoded({ extended: false }));
app.use(morgan('dev'));
//app.use(app.router);
app.use(routes);
...
Problem solved:
}).catch(function(err){
if(error.name === "SequelizeValidationError"){
next(err); //next(err); called inide this block no more 404 error
}
User input is now succesfully passed through the body-parser.
login.html(I have converted it to jade) is my login page which is opened at localhost:3000.
I send the form details to index.js(server).
Problem:
On console.log(username) I get output as undefined. Please help.
Have I used body-parser correctly ?
var express= require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var bodyParser = require('body-parser');
app.use(express.static('./Public'));
app.set('views', __dirname + '/tpl');
app.set('view engine', "jade");
app.engine('jade', require('jade').__express);
app.get("/", function(req, res){
res.render("login");
});
app.use(bodyParser.urlencoded({
extended : false
}));
app.use(bodyParser.json());
app.post('/', function(req,res) {
var username = req.body.name;
console.log(username);
});
http.listen(3000, function(){
console.log('listening on *:3000');
});
html code: (login.html)
<html>
<body>
<form action="/" method="post" enctype="multipart/form-data">
<fieldset>
<label for="name">Name:</label>
<input type="text" id="name" name="name" placeholder="Enter your full name" />
<br />
<label for="email">Email:</label>
<input type="email" id="email" name="email" placeholder="Enter your email address" />
<br />
<input type="submit" value="Create Profile" />
</fieldset>
</form>
<script>
var socket = io.connect("http://loacalhost:3000");
</script>
</body>
</html>
If you look documentation of body-parser you can notice this:
This does not handle multipart bodies, due to their complex and
typically large nature. For multipart bodies, you may be interested in
the following modules:
busboy and connect-busboy multiparty and connect-multiparty formidable
multer
So you have to either change enctype="multipart/form-data" to for example enctype="application/json" or to use some other module.
Hope that I have helped you.
