I have a simple form for login, the problem is when i press "Submit", the request.body on server side is empty.I saw that bodyParser is a fundamental part but in my case it's declared before the routes, so i think the problem is another. this is my server page App.js
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', index);
app.use('/users', users);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
app.listen(3000);
module.exports = app;
this is index.js
var express = require('express');
var router = express.Router();
function Login(req, res){
var mongoClient = require('mongodb').MongoClient;
mongoClient.connect('mongodb://localhost:27017/squaredDB', function(err, db) {
if(err) throw err;
db.collection('users').find({email: req.body.email}, function(err, data){
console.log(req.body);
});
});
}
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
router.post('/', function(req, res, next) {
Login(req, res);
res.render('app-home', { title: '' });
});
module.exports = router;
this is my jade template form:
form(method="post" action="/")
label Email
input(type="text" placeholder="Email")
label Password
input(type="password" placeholder="Password")
input(type="submit" value="login")
You're missing name attributes for your input fields in your template. Without those the browser won't submit them in the form.
Add a name attribute to your input field it will now be able to access the field via request like req.body.name
<form action="/", method="POST">
<input type="text" placeholder="name" name="name">
<button type="submit">Submit</button>
</form>

I'm trying to make a simple file upload system but everytime I submit my uploaded file I get a 404 error. I've tried various different names and paths but all of them fail instantly. When I press submit, the browser tries to redirect to /upload then returns the 404 error. I'm new to node.js so it may as well be very simple to solve but I couldn't find it.
I've tried 2 different modules, formidable and express-fileupload. Both return the same error.
./views/test2.ejs

you used app.use('/test2', test2); for the /upload routing
So form action should be "/test2/upload"

In my index page there is a link which link which directs user to a signup page. When I click on the link which is supposed to direct me to "http://localhost:3000/signup", it shows Error 404 Not found error. I am new to NodeJs. Any help is much appreciated. Thank you.
Changed the link in index.ejs to
Sign Up Here
Added this handler to users.js
router.get('/signup',function(req,res,next){

First of all, to use req.body you need to use body-parser or busboy, connect-busboy, multiparty, connect-multiparty, formidable, multer etc. - see:
https://github.com/expressjs/body-parser
Also, what is this route supposed to be:
router.post('#', function(req, res, next) {
This character is not valid in the URL path amd needs to be URL-encoded on the client side to work. Are you sure that this is the route your need?
If you are thinking about the fragment part of the URL (as in http://host/path#fragment) then it is not sent during the HTTP request at all. See:
https://en.wikipedia.org/wiki/Fragment_identifier
I created two Mongoose schemas and want to test them with Postman.
When I send a post HTTP request my parameters doesn't change the default value from the AnimalSchema nor does at StorySchema.
var mongoose = require('mongoose');
var AnimalSchema = new mongoose.Schema({
name: {type : String, default: ""},
audio: {type : String, default: ""},
image: {type : String, default: ""}
});
mongoose.model('Animal', AnimalSchema);
var mongoose = require('mongoose');
var express = require('express');
var router = express.Router();
var Animal = mongoose.model('Animal');
var Story = mongoose.model('Story');
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
router.get('/animals', function(req, res, next){
Animal.find(function(err, animals){
if(err){
return next(err);
}
res.json(animals);
});
});
router.post('/animals', function(req, res, next){
var animal = new Animal(req.body);
animal.save(function(err,animal){
if(err){return next(err);}
res.json(animal);
});
});
router.get('/stories', function(req, res, next){
Story.find(function(err, stories){
if(err){return next(err);}
res.json(stories);
});
});

I think I made an error in my app.js file. But not sure where it is.
Anyone knows what I did wrong?
I would do something like
{*(Model)}.findById(id, function(err, animal) {
if (err) console.log(err);
{update new values here in animal with the ones you are receiving in the request}
animal.save(function(err) {
if (err) console.log(err);
});
});
I am using express and I have a catch all route
router.use('*',function(){...});
and a root route
router.use('/', function(){...});
I have this route placed after the
app.use(express.static(path.join(__dirname, 'public')));
this causes my routes to not fire when placed below the previous line. however if I put my routes above it my catch all is also called on static asset requests. is there a way I can catch all requests except for the assets in my public folder including the route '/'? I don't want to resort to using regex and having to update it every time a directory is added to the public directory.
