PassportJS没有将注册数据传递给数据库，可能是数据库连接问题
我正在使用scotch.io教程为我正在处理的应用程序设置PassportJS本地登录。在设置我的注册/登录页面，MongoDB，PassportJS之后，我尝试进行测试“帐户”，并且......没有任何反应。没有重定向，没有flash消息，没有。似乎没有任何东西被拿起来发布到数据库。我在下面列出了相关的脚本。我试图尽可能忠实于教程布局（来源：https://scotch.io/tutorials/easy-node-authentication-setup-and-local）。
index.js（服务器的入口点）
// load dependencies
var express = require('express');
var app = express();
var path = require('path');
var mongoose = require('mongoose');
var passport = require('passport');
var flash = require('connect-flash');

var morgan = require('morgan');
var cookieParser = require('cookie-parser');

var session = require('express-session');
var configDB = require('./config/database.js');
// setup views
var ejs = require('ejs');
var engine = require('ejs-locals');
//database configuration
mongoose.connect(configDB.url);
require('./config/passport')(passport);
app.use(morgan('dev'));
app.use(cookieParser());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
//view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use('/public', express.static(path.join(__dirname, 'public')));
// required for passport
app.use(session({

}));
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // for flash messages stored in-session
// routes
require('./routes')(app, passport);
app.listen(3000, function () {
console.log('Example app listening on port 3000!')
});
passport.js（护照设置）
var LocalStrategy = require('passport-local').Strategy;
var User = require('../user');
module.exports = function(passport) {
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
passport.use('local-signup', new LocalStrategy({
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true
},
function(req, email, password, done) {
process.nextTick(function() {
User.findOne({ 'local.email': email }, function(err, user) {
if (err)
return done(err);
if (user) {
return done(null, false, req.flash('signupMessage', 'That e-mail address is already taken.'));
} else {
var newUser = new User;
newUser.local.email = email;
newUser.local.password = newUser.generateHash(password);
newUser.save(function(err) {
if (err)
throw err;
return done(null, newUser);
});
}
});
});
}));
passport.use('local-login', new LocalStrategy({
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true
},
function(req, email, password, done) {
User.findOne({ 'local.email': email }, function(err, user) {
if (err)
return done(err);
if (!user)
return done(null, false, req.flash('loginMessage', 'User not found.'));
if(!user.validPassword(password))
return done(null, false, req.flash('loginMessage', 'Invalid password, please try again.'));
return done(null, user);
});
}));
};
/config/database.js
module.exports = {
'url': 'mongodb://localhost:27017/users/'
}
routes.js
module.exports = function(app, passport) {
app.get('/', function (req, res) {
res.render('pages/index');
});
app.get('/login', function (req, res) {
res.render('pages/login', { message: req.flash('loginMessage') });
});
app.get('/signup', function (req, res) {
res.render('pages/signup', { message: req.flash('signupMessage') });
});
app.post('/signup', passport.authenticate('local-signup', {
successRedirect: '/profile',
failureRedirect: '/signup',
failureFlash: true
}));
app.post('/login', passport.authenticate('local-login', {
successRedirect: '/profile',
failureRedirect: '/login',
failureFlash: true
}));
app.get('/profile', isLoggedIn, function(req, res) {
res.render('profile.ejs', {
user: req.user
});
});
app.get('/addroom', function (req, res) {
res.render('pages/addroom.ejs', {
message: req.flash('addroomMessage')
});
});
app.get('/propconfig', function (req, res) {
res.render('pages/propconfig.ejs', {
message: req.flash('propconfigMessage')
});
});
app.get('/logout', function(req, res) {
req.logout();
res.redirect('/');
});
};
// route middleware to ensure a user is logged in
function isLoggedIn(req, res, next) {
if (req.isAuthenticated())
return next();
res.redirect('/');
}
user.js（用户架构）
// load dependencies
var mongoose = require('mongoose');
var bcrypt = require('bcrypt');
// define user schema
var userSchema = mongoose.Schema({
local: {
email: String,
password: String
}
});
// METHODS
// generating a hash
userSchema.methods.generateHash = function(password) {
return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null);
};
// checking if password is valid
userSchema.methods.validPassword = function(password) {
return bcrypt.compareSync(password, this.local.password);
};
// creating model for user to expose to app
module.exports = mongoose.model('User', userSchema);
最后是signup.ejs（注册用户界面的模板）

更新：我注释掉了我正在使用的电子邮件验证脚本，现在发生了POST操作（之前为什么不是，我不知道），但它仍然没有达到数据库。
更新＃2：我尝试在调试模式下运行服务器。控制台返回了这些信息：

2 个答案:
答案 0 :(得分：2)
首先改变你这样的本地策略
passport.use(new LocalStrategy(
{
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true
}, function () {
//LocalStrategy verify callback
}
));
然后改变您的路线/注册
app.post('/signup', function (req, res, next) {
passport.authenticate('local', {failureRedirect: '/login'},
function (req, email, password, done) {
process.nextTick(function () {
User.findOne({'local.email': email}, function (err, user) {
if (err)
return done(err);
if (user) {
return done(null, false, req.flash('signupMessage', 'That e-mail address is already taken.'));
} else {
var newUser = new User;
newUser.local.email = email;
newUser.local.password = newUser.generateHash(password);
newUser.save(function (err) {
if (err){
throw err;}
//res.redirect("/path")
return done(null, newUser);
});
}
});
});
})(req, res, next);
});
您可以像这样
重定向到res.redirect（“/ path”）中的其他页面您在路线中定义的那条路线，即
app.post('/signup', passport.authenticate('local-signup', {
successRedirect: '/profile',
failureRedirect: '/signup',
failureFlash: true
}));
它无法正常工作，因为您无法直接在路由中定义passport.authenticate，并且您的数据库连接正常，它从数据库中获取结果没有数据库连接问题。

在routes.js中，我修改了护照以使用passport.js中定义的local-signup而不是现有的函数：
