Passport在NodeJS后端无法正常工作

npm install passport passport-local

const express = require('express');
const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;

const app = express();

passport.use(new LocalStrategy(
  function(username, password, done) {
    // 这里进行用户验证逻辑
  }
));

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

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

passport.deserializeUser(function(id, done) {
  // 这里根据用户ID查找用户对象
  User.findById(id, function(err, user) {
    done(err, user);
  });
});

app.post('/login', 
  passport.authenticate('local', { failureRedirect: '/login' }),
  function(req, res) {
    res.redirect('/');
  });

const session = require('express-session');

app.use(session({
  secret: 'your_secret_key',
  resave: false,
  saveUninitialized: false
}));

const GoogleStrategy = require('passport-google-oauth20').Strategy;

passport.use(new GoogleStrategy({
    clientID: GOOGLE_CLIENT_ID,
    clientSecret: GOOGLE_CLIENT_SECRET,
    callbackURL: "http://localhost:3000/auth/google/callback"
  },
  function(accessToken, refreshToken, profile, done) {
    // 这里处理用户信息
  }
));
