如何使用SQLAlchemy将远程mySQL数据库连接到flask应用？

pip install Flask SQLAlchemy mysql-connector-python

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

# 配置数据库URI
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql+mysqlconnector://username:password@hostname:port/database_name'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False

db = SQLAlchemy(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True, nullable=False)
    email = db.Column(db.String(120), unique=True, nullable=False)

    def __repr__(self):
        return '<User %r>' % self.username

with app.app_context():
    db.create_all()

@app.route('/add_user/<username>/<email>')
def add_user(username, email):
    new_user = User(username=username, email=email)
    db.session.add(new_user)
    db.session.commit()
    return 'User added!'

@app.route('/get_users')
def get_users():
    users = User.query.all()
    return {'users': [user.username for user in users]}
