node.js - Passport.js 记住我功能

Question

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);
    });
  }
));

帖子

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('/');
  });

我正在尝试将“记住我”功能(上面)实现到我现有的应用程序中，但我无法做到。当我将 RememberMeStrategy 添加到我的 login.js 中时，它会抛出

ReferenceError: RememberMeStrategy is not defined

错误。这里缺少什么？

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');
};

登录.js

    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) {

        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);

    // 'rendering' can be used to format api calls (if you have an api)
    // into either html or json depending on the 'Accept' request header

该错误只是说您在调用 RememberMeStrategy 函数之前没有定义它(您正在使用 new 但在 Javascript 中，这只是用称为 this 的特殊变量)。您需要首先require该模块，在本例中:

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