如何在node.js sequalize中编写连接查询？

const Sequelize = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql', // 根据实际情况选择适当的数据库类型
});

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

const Post = sequelize.define('Post', {
  title: Sequelize.STRING,
  content: Sequelize.TEXT,
});

User.hasMany(Post); // 定义一对多关系
Post.belongsTo(User); // 定义多对一关系

User.findAll({
  include: [Post], // 包含关联模型Post
}).then(users => {
  users.forEach(user => {
    console.log(user.username);
    user.Posts.forEach(post => {
      console.log(post.title);
    });
  });
}).catch(err => {
  console.error('查询失败：', err);
});
