我正在使用 scotch.io 教程为我正在开发的应用程序设置 PassportJS 本地登录。在设置了我的注册/登录页面、MongoDB、PassportJS 之后，我尝试创建一个测试“帐户”，然后……没有任何反应。没有重定向，没有 Flash 消息，什么都没有。似乎没有任何东西可以发布到数据库。我在下面包括了相关的脚本。我尽量忠实于教程布局(来源:https://scotch.io/tutorials/easy-node-authentication-setup-and-local)。

index.js(服务器入口点)

// 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 LocalStrategy = require('passport-local').Strategy;

var morgan = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-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({ 
    secret: 'ilovescotchscotchyscotchscotch',
    resave: true,
    saveUninitialized: true
}));
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( Passport 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/'
}

路由.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(用户模式)

// 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 UI 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 POST 操作正在发生(为什么之前没有，我不知道)，但它仍然没有到达数据库。

更新 #2:我尝试在 Debug模式下运行服务器。控制台返回此信息:

GET /signup 304 34.791 ms - -
  express:router dispatching POST /signup +28s
  express:router query  : /signup +0ms

与此同时，浏览器停留在 “等待本地主机...” 大约 2 或 3 分钟(没有崩溃或超时)，然后最终返回“本地主机页面不工作

localhost 没有发送任何数据。 ERR_EMPTY_RESPONSE”

最佳答案

首先像这样改变你的本地策略

passport.use(new LocalStrategy(
    {
        usernameField: 'email',
        passwordField: 'password',
        passReqToCallback: true
    }, function () {
        //LocalStrategy verify callback
    }
));

然后像这样改变你的路线/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);
});

你可以像这样从 res.redirect("/path") 重定向到其他页面

您在 route 定义的路线即

app.post('/signup', passport.authenticate('local-signup', {
    successRedirect: '/profile',
    failureRedirect: '/signup',
    failureFlash: true
}));

它没有工作，因为你不能直接在你的路由中定义 passport.authenticate，而且你的数据库连接工作正常，它从数据库中获取结果，数据库连接没有问题。

关于javascript - PassportJS 没有将注册数据传递到数据库，可能是数据库连接问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42743705/
