flask中的配置文件是一个flask.config.Config对象(继承字典),默认配置为: { ‘DEBUG‘: get_debug_flag(default=False), 是否开启Debug模式 ‘TESTING‘: False, 是否开启测试模式 ‘PROPAGATE_EXCEPTIONS‘: None, ‘PRESERVE_CONTEXT_ON_EXCEPTION‘: None, ‘SECRET_KEY‘: None, ‘PERMANENT_SESSION_LIFETIME‘: timedelta(days=31), ‘USE_X_SENDFILE‘: False, ‘LOGGER_NAME‘: None, ‘LOGGER_HANDLER_POLICY‘: ‘always‘, ‘SERVER_NAME‘: None, ‘APPLICATION_ROOT‘: None, ‘SESSION_COOKIE_NAME‘: ‘session‘, ‘SESSION_COOKIE_DOMAIN‘: None, ‘SESSION_COOKIE_PATH‘: None, ‘SESSION_COOKIE_HTTPONLY‘: True, ‘SESSION_COOKIE_SECURE‘: False, ‘SESSION_REFRESH_EACH_REQUEST‘: True, ‘MAX_CONTENT_LENGTH‘: None, ‘SEND_FILE_MAX_AGE_DEFAULT‘: timedelta(hours=12), ‘TRAP_BAD_REQUEST_ERRORS‘: False, ‘TRAP_HTTP_EXCEPTIONS‘: False, ‘EXPLAIN_TEMPLATE_LOADING‘: False, ‘PREFERRED_URL_SCHEME‘: ‘http‘, ‘JSON_AS_ASCII‘: True, ‘JSON_SORT_KEYS‘: True, ‘JSONIFY_PRETTYPRINT_REGULAR‘: True, ‘JSONIFY_MIMETYPE‘: ‘application/json‘, ‘TEMPLATES_AUTO_RELOAD‘: None, } 方式一: app.config[‘DEBUG‘] = True PS: 由于Config对象本质上是字典,所以还可以使用app.config.update(...) 方式二: app.config.from_pyfile("python文件名称") 如: settings.py DEBUG = True app.config.from_pyfile("settings.py") app.config.from_envvar("环境变量名称") 环境变量的值为python文件名称名称,内部调用from_pyfile方法 app.config.from_json("json文件名称") JSON文件名称,必须是json格式,因为内部会执行json.loads app.config.from_mapping({‘DEBUG‘:True}) 字典格式 app.config.from_object("python类或类的路径") app.config.from_object(‘pro_flask.settings.TestingConfig‘) settings.py class Config(object): DEBUG = False TESTING = False DATABASE_URI = ‘sqlite://:memory:‘ class ProductionConfig(Config): DATABASE_URI = ‘mysql://[email protected]/foo‘ class DevelopmentConfig(Config): DEBUG = True class TestingConfig(Config): TESTING = True PS: 从sys.path中已经存在路径开始写 PS: settings.py文件默认路径要放在程序root_path目录,如果instance_relative_config为True,则就是instance_path目录
下面这种是主流的配置文件,通过类的方式
