问题
I am trying to login my user in the node application, using OrientDB as the database and node js and express. I have imported passport actually adopted the solution from one of my mongo db projects.
The Problem is that when I try to login I get [object, object] but no errors.
This is what my code looks like:
user model file:
var db = require('../utils/oriento.js');
const OrientDB = require('orientjs');
var User = function (data) {
this.data = {
name: data.name,
email: data.email,
password: data.password,
id: data.id,
rid: data.rid
};
}
User.prototype.data = {}
User.findByID = function(id, callback){
db.select().from('Account').where({id: id}).one()
.then(function (user) {
if (user === undefined) {
return callback(false);
} else {
callback(new User(user));
}
});
}
module.exports = User;
So in OrientDB I have a class called Account, it has properties name, email, password and id. Currently my routes for login and register are in the app.js (to be changed later).
I am able to register, my password is successfully hashed and a new user is create.
My app.js file:
const express = require('express');
const path = require('path');
const exphbs = require('express-handlebars');
const methodOverride = require('method-override');
const flash = require('connect-flash');
const session =require('express-session');
const bodyParser = require('body-parser');
const bcrypt = require('bcryptjs');
const passport = require('passport');
const OrientDB = require('orientjs');
const app = express();
// Load routes
const users = require('./routes/users');
// Passport config
require('./config/passport')(passport);
// Handlebars middleware
app.engine('handlebars', exphbs({
defaultLayout: 'main'
}));
app.set('view engine', 'handlebars');
// Body Parser middleware
app.use(bodyParser.urlencoded({ extended: false}));
app.use(bodyParser.json());
// static folder
app.use(express.static(path.join(__dirname, 'public')));
//method override middleware
app.use(methodOverride('_method'));
// Express Session middleware
app.use(session({
secret: 'secret',
resave: true,
saveUninitialized: true,
}));
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());
// global variables
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();
});
// index route
app.get('/', (req, res)=>{
const title = 'welcome1';
res.render('index', {
title: title
});
});
// About route
app.get('/about', (req, res)=>{
res.render('about');
});
// User login Route
app.get('/users/login', (req, res) => {
res.render('users/login');
});
// User Register Route
app.get('/users/register', (req, res) => {
res.render('users/register');
});
// Login Form Post
app.post('/users/login', (req, res, next) => {
passport.authenticate('local', {
successRedirect: '/',
failureRedirect: '/users/login',
failureFlash: true
})(req, res, next);
});
// Register Form Post
app.post('/users/register', (req, res) => {
var ODatabase = require('orientjs').ODatabase;
var db = new ODatabase({
host: '192.168.0.107',
port: 2424,
username: 'admin',
password: 'admin',
name: 'paas1'
});
let name = req.body.name;
let email = req.body.email;
let password = req.body.password;
let status = 'ACTIVE';
bcrypt.genSalt(10, (err, salt) => {
bcrypt.hash(password, salt, (err, hash) => {
if(err) throw err;
password = hash;
const queryString = 'insert into Account (name, password, status, email) values ' + '(' + '"' + name + '"' +',' + ' "' + password + '"' + ',' + ' "' + status + '"' + ',' + '"' + email + '"' + ')';
console.log(queryString);
db.open().then(function(){
return db.query(queryString);
});
});
req.flash('success_msg', 'You are now registered');
res.redirect('/users/login');
});
});
const port = 5000;
app.listen(port, () => {
console.log(`Server started on port ${port}`);
});
The oriento.js file is simply there to create a Database connection between my app and the OrientDB database. Following is the code:
// instantiate it once and share in multiple places(models), since it offers
// connection pooling
// Connect to Database
var Oriento = require('orientjs');
var orientserver = Oriento({
host: '192.168.0.107',
port: 2424,
username: 'root',
password: 'mypassword'
});
var db = orientserver.use({
name: 'paas1',
username: 'admin',
password: 'admin'
});
console.log('Using database: ' + db.name);
module.exports = db;
Lastly this is my passport.js file:
const LocalStrategy = require('passport-local').Strategy;
const OrientDB = require('orientjs');
const bcrypt = require('bcryptjs');
const express = require('express');
const session =require('express-session');
const bodyParser = require('body-parser');
const db = require('../utils/oriento.js');
User = require("../models/user.js");
const Schema = OrientDB.Schema
// Load user model
//const User = mongoose.model('users');
module.exports = function(passport){
passport.use(new LocalStrategy({usernameField: 'email'}, (email, password, done) => {
// Match user
db.select().from('Account').where({
email: email
}).one().then(user => {
if(!user){
return done(null, false, {message: 'No user found'});
}
// Match password
bcrypt.compare(password, user.password, (err, isMatch) => {
if(err) throw err;
if(isMatch){
return done(null, user);
}else{
return done(null, false, {message: 'Password incorrect'});
}
})
})
}));
passport.serializeUser(function(user, done){
console.log('serializeUser: ' + user.id)
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.findByID(id, function(err, user){
console.log(user)
if(!err) done(null, user);
else done(err, null)
})
});
}
As you can see from the code, I am able to successfully get all the fileds for the user in the serializeUser function, but nothing in the deserializeUser. I am guessing the problem is not with my database connection since I am able to create new users, get their properties to the point of serialize user.
But it is not storing the user in the session i think and the desirializeUser just returns [object, object] on a blank web page instead of taking me to the index route as defined in the app.js
// Login Form Post
app.post('/users/login', (req, res, next) => {
passport.authenticate('local', {
successRedirect: '/',
failureRedirect: '/users/login',
failureFlash: true
})(req, res, next);
});
Please advise what am I doing wrong. Thanks in advance.
回答1:
var db = require('../utils/oriento.js');
const OrientDB = require('orientjs');
var User = function (data) {
return this.data = {
name: data.name,
email: data.email,
password: data.password,
id: data.id, rid: data.rid
};
}
User.prototype.data = {} ...
