如何创建可靠的flask-SQLAlchemy与服务器端事件的交互？

from flask_sqlalchemy import SQLAlchemy

db = SQLAlchemy()

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(50), nullable=False)
    email = db.Column(db.String(50), unique=True, nullable=False)

from flask import Flask

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'database://username:password@localhost/db_name'
db.init_app(app)

@app.route('/create_tables')
def create_tables():
    db.create_all()
    return 'Tables created successfully!'

from flask import Blueprint

events = Blueprint('events', __name__)

@events.route('/event_handler', methods=['POST'])
def event_handler():
    # 处理事件逻辑
    return 'Event handled successfully!'

app.register_blueprint(events, url_prefix='/events')

// 前端代码示例
fetch('/events/event_handler', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ /* 事件数据 */ })
})

from flask import request

@events.route('/event_handler', methods=['POST'])
def event_handler():
    data = request.json
    new_user = User(name=data['name'], email=data['email'])
    db.session.add(new_user)
    db.session.commit()
    return 'Event handled successfully!'
