Passport.js记得我的function

https://github.com/jaredhanson/passport-remember-me

passport.use(new RememberMeStrategy( function(token, done) { Token.consume(token, function (err, user) { if (err) { return done(err); } if (!user) { return done(null, false); } return done(null, user); }); }, function(user, done) { var token = utils.generateToken(64); Token.save(token, { userId: user.id }, function(err) { if (err) { return done(err); } return done(null, token); }); } )); 

岗位

 app.post('/login', passport.authenticate('local', { failureRedirect: '/login', failureFlash: true }), function(req, res, next) { // issue a remember me cookie if the option was checked if (!req.body.remember_me) { return next(); } var token = utils.generateToken(64); Token.save(token, { userId: req.user.id }, function(err) { if (err) { return done(err); } res.cookie('remember_me', token, { path: '/', httpOnly: true, maxAge: 604800000 }); // 7 days return next(); }); }, function(req, res) { res.redirect('/'); }); 

我试图实现记住我function（上面）到我现有的应用程序，但我不能做到这一点。 当我将RememberMeStrategy添加到我的login.js中时，它会抛出

ReferenceError：RememberMeStrategy没有定义

错误。 这里缺less什么？

index.js

 var rendering = require('../util/rendering'); var express = require('express'); var router = express.Router(); exports.home = function(req, res) { res.render('index/index'); }; exports.userHome = function(req, res) { res.render('index/user-home'); }; 

login.js

 var crypto = require('crypto'), passport = require('passport'), passportRememberMe = require('passport-remember-me'), passportLocal = require('passport-local'), data = require('../models/auth')(); exports.registerPage = function (req, res) { res.render('login/register', {username: req.flash('username')}); }; exports.registerPost = function (req, res) { var vpw = req.body.vpw; var pwu = req.body.pw; var un = req.body.un; req.flash('username', un); if (vpw !== pwu) { req.flash('error', 'Your passwords did not match.'); res.redirect('/register'); return; } req.checkBody('un', 'Please enter a valid email.').notEmpty().isEmail(); var errors = req.validationErrors(); if (errors) { var msg = errors[0].msg; req.flash('error', msg); res.redirect('/register'); return; } var new_salt = Math.round((new Date().valueOf() * Math.random())) + ''; var pw = crypto.createHmac('sha1', new_salt).update(pwu).digest('hex'); var created = new Date().toISOString().slice(0, 19).replace('T', ' '); new data.ApiUser({email: un, password: pw, salt: new_salt, created: created}).save().then(function (model) { passport.authenticate('local')(req, res, function () { res.redirect('/home'); }) }, function (err) { req.flash('error', 'Unable to create account.'); res.redirect('/register'); }); }; exports.loginPage = function (req, res) { res.render('login/index', {username: req.flash('username')}); }; exports.checkLogin = function (req, res, next) { passport.authenticate('local', function (err, user, info) { if (err || !user) { req.flash('username', req.body.un); req.flash('error', info.message); return res.redirect('/login'); } req.logIn(user, function (err) { if (err) { req.flash('error', info.message); return res.redirect('/login'); } req.flash('success', 'Welcome!'); return res.redirect('/home'); }); })(req, res, next); }; exports.logout = function (req, res) { req.logout(); req.flash('info', 'You are now logged out.'); res.redirect('/login'); }; 

routes.js

 var rendering = require('./util/rendering'), indexController = require('./controllers/index'), loginController = require('./controllers/login'); module.exports = function (app, passport) { // Home app.get('/', indexController.home); app.get('/home', ensureAuthenticated, indexController.userHome); // Auth app.get('/register', loginController.registerPage); app.post('/register', loginController.registerPost); app.get('/login', loginController.loginPage); app.post('/login', loginController.checkLogin); app.get('/logout', loginController.logout); // 'rendering' can be used to format api calls (if you have an api) // into either html or json depending on the 'Accept' request header app.get('/apitest', function(req, res) { rendering.render(req, res, { 'data': { 'test': { 'testsub': { 'str': 'testsub hello world' }, 'testsub2': 42 }, 'test2': 'hello world' } }); }) // Auth Middleware function ensureAuthenticated(req, res, next) { if (req.isAuthenticated()) { return next(); } res.redirect('/login'); } } 

server.js

 var dbConfig; try { // Look for dev conf for local development dbConfig = require('./config/db.dev.conf.js'); } catch(e) { try { // production conf? dbConfig = require('./config/db.conf.js'); } catch(e) { console.log('Startup failed. No db config file found.'); return false; } } var knex = require('knex')({ client: 'mysql', connection: dbConfig }), express = require('express'), bodyParser = require('body-parser'), cookieParser = require('cookie-parser'), cookieSession = require('cookie-session'), serveStatic = require('serve-static'), expressValidator = require('express-validator'), flash = require('connect-flash'), swig = require('swig'), passport = require('passport'), passportRememberMe = require('passport-remember-me'), passportLocal = require('passport-local'), crypto = require('crypto'), Bookshelf = require('bookshelf'), messages = require('./util/messages'); var app = express(); Bookshelf.mysqlAuth = Bookshelf(knex); app.use(cookieParser('halsisiHHh445JjO0')); app.use(cookieSession({ keys: ['key1', 'key2'] })); app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json()); app.use(expressValidator()); app.use(passport.initialize()); app.use(passport.session()); app.use(passport.authenticate('remember-me')); app.use(flash()); app.use(serveStatic('./public')); //app.use(express.favicon(__dirname + '/public/images/shortcut-icon.png')); app.use(messages()); app.engine('html', swig.renderFile); app.set('view engine', 'html'); app.set('views', __dirname + '/views'); require('./util/auth')(passport); require('./routes')(app, passport); app.listen(process.env.PORT || 3000); console.log('Listening on port 3000'); 

Answer 1

这个错误只是说你在调用它之前没有定义过RememberMeStrategy函数（你正在使用new但是在Javascript中只是用一个叫做this的特殊variables来调用一个函数）。 您需要首先require模块，在这种情况下：

 var RememberMeStrategy = require('passport-remember-me').Strategy; 

Answer 2

只需要在variablesRememberMeStrategy

 var RememberMeStrategy= require('passport-remember-me').Strategy;
