如何在Flask app中显示喜欢某条帖子的用户列表？

from flask import Flask, jsonify, request
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'your_database_uri'
db = SQLAlchemy(app)

# 定义帖子和用户的喜欢关系表格模型
class Like(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    post_id = db.Column(db.Integer, db.ForeignKey('post.id'))
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'))

# 定义帖子模型
class Post(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    # 添加其他帖子相关的字段...

# 定义用户模型
class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    # 添加其他用户相关的字段...

# 定义API端点
@app.route('/posts/<int:post_id>/likes', methods=['GET'])
def get_liked_users(post_id):
    likes = Like.query.filter_by(post_id=post_id).all()
    user_ids = [like.user_id for like in likes]

    users = User.query.filter(User.id.in_(user_ids)).all()

    user_list = []
    for user in users:
        user_data = {
            'id': user.id,
            'username': user.username,
            # 添加其他用户信息字段...
        }
        user_list.append(user_data)

    return jsonify(user_list)

if __name__ == '__main__':
    app.run()
