Javascript app.get（"；/api/current_user"；。在passport.js经过身份验证后不触发。节点

我是NodeJS新手，我正在尝试创建一个简单的web服务器。 我现在只使用NodeJS和Passport.js（使用谷歌策略）

目前，所有app.get（“”）调用在我未经身份验证时都能正常工作，但一旦我通过google身份验证并发生回调，我就无法再访问任何app.get路由。我尝试在arrow函数中设置一个断点，但它永远不会被调用，并且在使用auth cookie从浏览器加载时挂起

这是我目前的代码：

Index.js

const express = require('express');
const mongoose = require('mongoose');
const cookieSession = require("cookie-session");
const passport = require("passport");
const keys = require('./config/keys');
require('./models/User');
require('./services/passport');

mongoose.connect(keys.mongoURI);

const app = express();

app.use(
    cookieSession({
        maxAge: 30 * 24 * 60 * 60 * 1000,   //30 days
        keys: [keys.cookieKey]
    })
);

app.use(passport.initialize());
app.use(passport.session());

require('./routes/authRoutes')(app);

const PORT = process.env.PORT || 5000;
app.listen(PORT);

authrouts.js

   const passport = require('passport');

   module.exports = (app) => {
    app.get(
        "/auth/google",
        passport.authenticate('google', {
            scope: ['profile', 'email']
        })
    );

    app.get(
        '/auth/google/callback',
        passport.authenticate('google')
    );

    app.get("/api/logout", (req, res) => {
        req.logout();
        res.send(req.user);
    });

    app.get("/api/current_user", (req, res) => {
            res.send("test");//req.user);   //Tried as a test, is called when    
                                           //not authenticated, but does not get 
                                          //called when authenticated
    });
   }

passport.js

const passport = require('passport');
const googleStrategy = require('passport-google-oauth20');
const mongoose = require('mongoose');
const keys = require('../config/keys');
const User = mongoose.model("users");

passport.serializeUser((user, done) => {
 done(null, user.id);
});

passport.deserializeUser((id, done)=> {
    User.findById(id)
    .then(user =>{
        doen(null, user);
    });
});

passport.use(new googleStrategy({
    clientID: keys.googleClientID,
    clientSecret: keys.googleclientSecret,
    callbackURL: '/auth/google/callback'
    },
    (accessToken, refreshToken, profile, done) => {
        User.findOne({ googleId: profile.id })
        .then((existingUser) => {
            if (existingUser){
                //we already have a user
                done(null, existingUser);
            }
            else{
                new User({ googleId: profile.id })
                .save()
                .then (user => done(null, user));                
            }
        });
    })
);

这可能不会帮助任何人，除了检查打字错误

我在这里发现了我的问题：

passport.deserializeUser((id, done)=> {
    User.findById(id)
    .then(user =>{
        doen(null, user);
    });
});

注意不应该这样做

在这一点上，我没有收到帮助我的错误消息
