基本示例

• config.py

定義工廠函數(shù)

from flask import Flask
from config.settings import config
from api.views import api


def create_app(config_name):
    app = Flask(__name__)
    app.config.from_object(config[config_name])
    # 日志
    register_logging(app)
    # 注冊(cè)藍(lán)圖
    register_blueprints(app)
    # 數(shù)據(jù)庫(kù)
    register_database(app)
    # 異常處理
    register_errors(app)
    # 注冊(cè)自定義命令
    register_commands(app)

    return app


def register_logging(app):
    pass


def register_blueprints(app):
    app.register_blueprint(api, url_prefix='/api')


def register_database(app):
    pass


def register_errors(app):
    pass


def register_commands(app):
    pass

• settings.py

不同環(huán)境的配置(測(cè)試/生產(chǎn)/正式)

class BaseConfig:
    TEST = True
    NUM = 10


config = {

    'default': BaseConfig
}

• manage.py

總?cè)肟?/p>

from config.config import create_app


if __name__ == '__main__':

    app = create_app('default') # 默認(rèn)環(huán)境
    print(app.config['NUM']) # 獲取定義變量NUM
    
    app.run()
