Flask工厂函数

官网

我的目录结构

flask_project-- config-- __init__.py-- config.py-- settings.py-- other_app...-- manage.py

基本示例

• config.py

定义工厂函数

from flask import Flask
from config.settings import config
from api.views import apidef create_app(config_name):app = Flask(__name__)app.config.from_object(config[config_name])# 日志register_logging(app)# 注册蓝图register_blueprints(app)# 数据库register_database(app)# 异常处理register_errors(app)# 注册自定义命令register_commands(app)return appdef register_logging(app):passdef register_blueprints(app):app.register_blueprint(api, url_prefix='/api')def register_database(app):passdef register_errors(app):passdef register_commands(app):pass

• settings.py

不同环境的配置(测试/生产/正式)

class BaseConfig:TEST = TrueNUM = 10config = {'default': BaseConfig
}

• manage.py

总入口

from config.config import create_appif __name__ == '__main__':app = create_app('default') # 默认环境print(app.config['NUM']) # 获取定义变量NUMapp.run()
