Sequelize:如何将解密的值与req.body进行比较

const Sequelize = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql' // 根据你使用的数据库类型进行设置
});

const User = sequelize.define('User', {
  username: Sequelize.STRING,
  password: Sequelize.STRING
});

app.post('/login', async (req, res) => {
  const decryptedValue = // 获取解密的值
  const { username, password } = req.body;

  try {
    const user = await User.findOne({ where: { username } });
    if (user && user.password === decryptedValue) {
      // 登录成功
      res.status(200).send('Login successful');
    } else {
      // 登录失败
      res.status(401).send('Invalid username or password');
    }
  } catch (error) {
    // 处理错误
    res.status(500).send('Internal server error');
  }
});
