Using Express 4.14 I have a simple html form accepting username and password. I want to pass that info to a function that inserts it into my psql database. But first I verify if that user is already in the db. I keep getting the error at "let uname = req.body.name;"
Thanks for the help.
HMTL form:
<div>
<form class="" action="/register" method="post">
<input class="text-input" type="text" name="user[username]" value="" placeholder="Username">
<input class="text-input" type="password" name="user[password]" value="" placeholder="Password">
<input type="submit" value="Sign up">
</form>
</div>
my function to insert into db:
verifyUser(req, res, next) {
let uname = req.body.name;
db.any(`SELECT * FROM users WHERE name = uname LIMIT 1`)
.then(() => {
next();
})
my server setup:
'use strict'
require('dotenv').config({ silent: true });
const bodyParser = require('body-parser');
const express = require('express');
const logger = require('morgan');
const path = require('path');
const app = express();
const authRouter = require('./routes/auth/auth.js');
const loginRouter = require('./routes/login/login.js');
const apiRouter = require('./routes/api/apiRoute.js');
const profileRouter = require('./routes/profile/profile.js');
const regRouter = require('./routes/register/register.js');
const PORT = process.argv[2] || process.env.port || 3000;
app.use(logger('dev'));
app.use(express.static(path.join(__dirname, 'dist')));
app.use(express.static(path.join(__dirname, 'public')));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.listen(PORT, () => { console.log('app is listening on 3k')});
app.get('/', (req, res) => {
res.sendFile(path.join(__dirname, 'public/landing.html'));
});
app.get('/login', (req, res) => {
res.sendFile(path.join(__dirname, 'public/login.html'));
});
app.get('/signup', (req, res) => {
res.sendFile(path.join(__dirname, 'public/signup.html'));
});
app.use('/api', apiRouter);
app.use('/auth', authRouter);
app.use('/login', loginRouter);
app.use('/register', regRouter);
app.use('/profile', profileRouter);
regRouter: None of those console.logs actually return anything. So, there's that.
const regRouter = require('express').Router();
const { createUser } = require('../../models/user_model');
regRouter.get('/', (req, res) => {
console.log('register line 5')
res.render('register');
});
regRouter.post('/', createUser, (req, res) => {
console.log('register line 10')
res.render('landing');
});
module.exports = regRouter;
createUser:
function createUser(req, res, next) {
console.log('create user line 10');
let uname = req.body.name;
console.log('body', req.body);
let encryption = bcrypt.hashSync(req.body.password, SECRET);
db.any(`INSERT INTO users
(name, password)
VALUES ($1, $2);` [uname, encryption])
.then(() => {
next();
})
.catch(error => next(error));
};
In your html there isn't any input field with name attribute set to "name" or "password.
<input class="text-input" type="text" name="name" value="" placeholder="Username">
<input class="text-input" type="password" name="password" value="" placeholder="Password">

you can send put request to the given route because you don't have any put method attached to that route you are trying to access.
you have to have an
app.put("/",async(req,res)=>{
//code
})
or you can use
// this will be accessible by all HTTP methods
app.use("/",async(req,res)=>{
//code
})
in your code to be able to send a put request to the server.
I'm a newbie so be kind. I've been trying to learn passport via an online tutorial (this one, github here) and as far as I can tell I've recreated the code verbatim but I'm getting an error that the localhost didn't send any data. My full code is here. I'm pasting some code below but I'm honestly unsure which piece of code to post since I don't know where the error is occurring.
Here's the server app:
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var exphbs = require('express-handlebars');
var expressValidator = require('express-validator');
var flash = require('connect-flash');
var session = require('express-session');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var mongo = require('mongodb');
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/loginapp');
var db = mongoose.connection;
var routes = require('./routes/index');
var users = require('./routes/users');
//Init app
var app = express();
//View engine
app.set('views', path.join(__dirname, 'views'));
app.engine('handlebars', exphbs({defaultLayout: 'layout'}));
app.set('view engine', 'handlebars');
//body parser middleware
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.use(cookieParser());
//set static folder
app.use(express.static(path.join(__dirname, 'public')));
//express session middleware
app.use(session({
secret: 'secret',
saveUninitialized: true,
resave: true
}));
//passport init
app.use(passport.initialize());
app.use(passport.session());
//validator middleware-- this code is straight from the validator github page
app.use(expressValidator({
errorFormatter: function(param, msg, value) {
var namespace = param.split(',')
, root = namespace.shift()
, formParam = root;
while(namespace.length) {
formParam += '[' + namespace.shift() + ']';
}
return {
param : formParam,
msg : msg,
value : value
};
}
}));
//connect flash middleware
app.use(flash());
//global variables for flash messages
app.use(function (req, res, next) {
res.locals.success_msg = req.flash('success_msg');
res.locals.error_msg = req.flash('error_msg');
res.locals.error = req.flash('error');
res.locals.user = req.user || null;
next();
});
app.use('/', routes);
app.use('/users', users);
//set port
app.set('port', (process.env.PORT || 3000));
app.listen(app.get('port'), function() {
console.log('Server started on port ' + app.get('port'));
});
Here's the form:
<h2 class="page-header">Register</h2>
<form method="post" action="/users/register">
<div class="form-group">
<label>Name</label>
<input type="text" class="form-control" placeholder="Name" name="name">
</div>
<div class="form-group">
<label>Username</label>
<input type="text" class="form-control" placeholder="Username" name="username">
</div>
<div class="form-group">
<label>Email</label>
<input type="email" class="form-control" placeholder="Email" name="email">
</div>
<div class="form-group">
<label>Password</label>
<input type="password" class="form-control" placeholder="Password" name="password">
</div>
<div class="form-group">
<label>Confirm Password</label>
<input type="password" class="form-control" placeholder="Password" name="password2">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
And here's the user js:
var express = require('express');
var router = express.Router();
//register
router.get('/register', function(req, res) {
res.render('register');
});
//login
router.get('/login', function(req, res) {
res.render('login');
});
//register user
router.post('/register', function(req, res) {
var name = req.body.name;
var email = req.body.email;
var username = req.body.username;
var password = req.body.password;
var password2 = req.body.password2;
});
module.exports = router;
First things first: you are actually not doing anything on the post('/register'..)
You should save your model and return it if successful, something like this:
var schema = new mongoose.Schema({ name: 'string', email: 'string' });
var User = mongoose.model('User', schema);
//register user
router.post('/register', function(req, res) {
var name = req.body.name;
var email = req.body.email;
var user = new User({ name: name, email: email});
user.save(function (err) {
if (err) throw err;
res.send(user);
});
});
Of course you would define your model on a separate folder and import it to where it fits.
I want to save the information captured from an html form in a MongoDB database, I have the following code:
<!DOCTYPE html>
<html>
<head>
<title>Intro to Node and MongoDB</title>
</head>
<body>
<h1>Into to Node and MongoDB</h1>
<form method="post" action="/addname">
<label>Enter Your Name</label><br>
<input type="text" name="firstName" placeholder="Enter first name..." required>
<input type="text" name="lastName" placeholder="Enter last name..." required>
<input type="submit" value="Add Name">
</form>
</body>
</html>
And the following javascript code would be my app.js
var express = require("express");
var app = express();
var port = 3000;
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
var mongoose = require("mongoose");
/*
mongoose.Promise = global.Promise;mongoose.connect("mongodb://localhost:27017/node-demo");
*/
var promise = mongoose.connect('mongodb://localhost:27017/node-demo', {
useMongoClient: true,
/* other options */
});
var nameSchema = new mongoose.Schema({
firstName: String,
lastName: String
});
var User = mongoose.model("User", nameSchema);
app.use("/", (req, res) => {
res.sendFile(__dirname + "/index.html");
});
app.post("/addname", (req, res) => {
var myData = new User(req.body);
myData.save()
.then(item => {
res.send("item saved to database");
})
.catch(err => {
res.status(400).send("unable to save to database");
});
});
app.listen(port, () => {
console.log("Server listening on port " + port);
});
Apparently the post request is working, filling in the fields and pressing the input type submit, however when checking the database is empty, just as it was when it was created. Does anyone know why I do not save the information?
I run your code here and the app.post was not called. It's because you're using app.use to send the index.html. app.use is used to bind middleware to your application. Instead, you should use app.get, which tells express to listen for requests to / and run the function when it sees one.
app.get("/", (req, res) => {
res.sendFile(__dirname + "/index.html");
});
