护照: req.isAuthenticated()不是一个函数，req.user也不是由护照设置的

Question

我正在使用MERN栈创建一个web应用程序，我想为其实现google OAuth和passport.js，并为此使用“快速会话”和“passport.js”。一切似乎都如期而至，但我得到了一个error: req.isAuthenticated isn't function。另外，the value of req.user is "undefined"但是，cookie正在生成，并成功地存储在MongoDB中。我对节点和护照都是新手，所以我找不到问题。另外，对于以前问到的关于同样错误的问题的解决方案对我来说是行不通的。

这是错误

我还添加了代码以供参考。

代码( server.js )

const dotenv = require("dotenv");
dotenv.config();
const express = require("express");
const cors = require("cors");
const bodyParser = require("body-parser");
const mongoose = require("mongoose");
const passport = require("passport");
const session = require("express-session");
const MongoStore = require("connect-mongo");
const authRouter = require("./routes/auth");
const Info = require("./models/Info");

const { User, userSchema } = require("./models/Users");
const GoogleStrategy = require("passport-google-oauth20").Strategy;
const startDB = require("./models/db");

const app = express();
const PORT = process.env.PORT || 8000;

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.use(
    cors({
        origin: "http://localhost:3000",
        methods: "GET,POST,PUT,DELETE",
        credentials: true,
    })

app.use(
    session({
        secret: "some random string",
        resave: false,
        saveUninitialized: false,
        store: MongoStore.create({
            mongoUrl: "mongodb://0.0.0.0:37017/budgetDB",
        }),
    })
);

startDB();

app.use("/auth", authRouter);
app.use("/dashboard", recordsRouter);

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

require("./passport")(passport);

app.listen(PORT, () => {
    console.log(`Server started listening on port ${PORT}.....`);
});

代码( passport.js )

const { User } = require("./models/Users");
const GoogleStrategy = require("passport-google-oauth20").Strategy;

module.exports = function (passport) {
    passport.serializeUser((user, done) => {
        console.log(`From passport.js serializeUser: ${user}`);
        return done(null, user.id);
    });

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

    passport.use(
        new GoogleStrategy(
            {
                clientID: process.env.CLIENT_ID,
                clientSecret: process.env.CLIENT_SECRET,
                callbackURL: "http://localhost:8000/auth/google/callback",
                userProfileURL: "https://www.googleapis.com/oauth2/v3/userinfo",
            },

            async (accessToken, refreshToken, profile, done) => {
                const newUser = new User({
                    name: profile.displayName,
                    googleId: profile.id,
                });

                try {
                    const user = await User.findOne({ googleId: profile.id });
                    if (!user) {
                        user = await User.create(newUser);
                    }
                    return done(null, user);
                } catch (err) {
                    console.log(`Error From 'passport.js': ${err}`);
                    return done(err);
                }
            }
        )
    );
};

代码( auth.js )

const router = require("express").Router();
const passport = require("passport");

const CLIENT_URL = "http://localhost:3000";

router.get("/login/failed", (req, res) => {
    console.log(res);
    res.status(401).json({
        message: "login failed",
    });
});

router.get("/logout", (req, res) => {
    req.logout();
    res.redirect(CLIENT_URL);
});

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

router.get(
    "/google/callback",
    passport.authenticate("google", {
        failureRedirect: "/login/failed",
        successRedirect: CLIENT_URL + "/Dashboard",
    })
);

module.exports = router;

用户模型中的代码

const mongoose = require("mongoose");

const userSchema = new mongoose.Schema({
    name: String,
    googleId: String,
});

const User = mongoose.model("User", userSchema);

module.exports = { User, userSchema };

中间件订单是很重要的。将.use(passport...)放在.use(router...)之前
