import logging.config

LOGGING_CONFIG = {
    # version - 表示版本，该键值为从1开始的整数。该key必选，除此之外，其它key都是可选。
    "version": 1,
    # formatters - 日志格式化器，其value值为一个字典，该字典的每个键值对都代表一个Formatter
    "formatters": {

    "handlers": {

            "filename": "./log.txt",

    },
    "disable_existing_loggers": True,
    "root": {
        "handlers": ["console"],
        # 取root level和console的level最严格的日志等级，下面输出为INFO等级
        "level": "DEBUG"
    },
}

# 运行测试
logging.config.dictConfig(LOGGING_CONFIG)
logger = logging.getLogger("console_logger")
logger.debug('debug message')

logger = logging.getLogger("root")
logger.debug('debug message')
logger.info('info message')
logger.warning('warning message')
logger.error('error message')
logger.critical('critical message')
