定义获取 logger 的公共方法
def get_logger():
# create logger
logger = logging.getLogger(os.path.basename(__file__))
logger.setLevel(logging.DEBUG)
# create console handler and set level to debug
ch = logging.FileHandler(filename='mylog.log', encoding="utf-8")
ch.setLevel(logging.DEBUG)
# create formatter
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
# add formatter to ch
ch.setFormatter(formatter)
# add ch to logger
logger.addHandler(ch)
return logger
