from flask import Flask from flask_sqlalchemy import SQLAlchemy # 创建 Flask 应用程序实例 app = Flask(__name__) HOSTNAME = "#" PORT = 3306 USERNAME = "#" PASSWORD = "#" DATABASE = "#" # 配置数据库 URI app.config[ "SQLALCHEMY_DATABASE_URI"] = f'mysql+pymysql://{USERNAME}:{PASSWORD}@{HOSTNAME}:{PORT}/{DATABASE}?charset=utf8mb4' # 配置 SQLAlchemy 引擎选项 app.config['SQLALCHEMY_ENGINE_OPTIONS'] = {'pool_recycle': 280} # 初始化 SQLAlchemy db = SQLAlchemy(app) with app.app_context(): # 在应用上下文中执行数据库操作 # 尝试创建一个新的表格 try: db.create_all() # db.drop_all() print("数据库连接成功!") except Exception as e: print("数据库连接失败:", e) # 你的代码......
