使用passport.js身份验证的静态管理员？

npm install passport passport-local

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

// 定义静态管理员的用户名和密码
const adminUsername = 'admin';
const adminPassword = 'password';

// 使用本地策略进行身份验证
passport.use(new LocalStrategy(
  function(username, password, done) {
    if (username === adminUsername && password === adminPassword) {
      return done(null, { username: adminUsername });
    } else {
      return done(null, false, { message: 'Invalid credentials' });
    }
  }
));

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

app.get('/admin', (req, res) => {
  if (req.isAuthenticated()) {
    // 已通过身份验证，执行相应操作
    res.send('Welcome, admin!');
  } else {
    // 未通过身份验证，重定向到登录页面
    res.redirect('/login');
  }
});
