如何使用Passport.js成功登录后刷新用户的用户名？

npm install passport passport-local express-session

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

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

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

passport.use(new LocalStrategy(
  function(username, password, done) {
    // 在此处进行用户名和密码的验证逻辑
    // 如果验证成功，调用done(null, user)；如果验证失败，调用done(null, false)
  }
));

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

passport.deserializeUser(function(id, done) {
  // 根据用户id从数据库或其他存储中获取用户对象，并调用done(null, user)
});

app.post('/login', passport.authenticate('local', {
  successRedirect: '/profile',
  failureRedirect: '/login',
}));

app.get('/profile', function(req, res) {
  res.send('Welcome, ' + req.user.username);
});
