使用Passport在Google OAuth中出错

Question

我正在使用Passport.js尝试通过Google OAuth 2.0登录Node.js中的东西，但它给了我以下错误：

  

ReferenceError：在passport.js中未定义id

无法检测来自auth / google / callback的配置文件对象的id属性，这可能是导致此错误的原因之一。请提供帮助。

passport.js

const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;
const GoogleStrategy=require( 'passport-google-oauth2' ).Strategy;
const User = require('../models/User');
const configAuth = require('./auth');

module.exports = function(passport) {

    // used to serialize the user for the session
    passport.serializeUser(function(user, done) {
        done(null, user.id);
    });

    // used to deserialize the user
    passport.deserializeUser(function(id, done) {
        User.findById(id, function(err, user) {
            done(err, user);
        });
    });

/**
 * Sign in with Google.
 */
 passport.use(new GoogleStrategy({

         clientID        : configAuth.googleAuth.clientID,
         clientSecret    : configAuth.googleAuth.clientSecret,
         callbackURL     : configAuth.googleAuth.callbackURL,
         passReqToCallback: true
       },function(token, refreshToken, profile, done) {
      process.nextTick(function() {

        User.findOne({ 'google.id': profile.id }, function(err, user) {
          if (err)
            return done(err);
          if (user) {
            return done(null, user);
          } else {
            var newUser = new User();
            newUser.google.id = profile.id;
            newUser.google.token = token;
            newUser.google.name = profile.displayName;
            newUser.google.email = profile.emails[0].value;
            newUser.save(function(err) {
              if (err)
                throw err;
              return done(null, newUser);
            });
          }
        });
      });
    }));

routes.js

router.get('/profile',isLoggedIn, function(req, res) {
        res.render('profile.ejs', {
            user : req.user // get the user out of session and pass to template
        });
    });

  router.get('/auth/google', passport.authenticate('google', { scope : ['profile', 'email'] }));

// the callback after google has authenticated the user
router.get('/auth/google/callback',
passport.authenticate('google', {
  successRedirect: '/profile',
  failureRedirect: '/',
   }));
