# 第一步，创建一个logger
logger = logging.getLogger()
logger.setLevel(logging.INFO)  # Log等级总开关
# 第二步，创建一个handler，用于写入日志文件
rq = time.strftime('%Y%m%d%H%M', time.localtime(time.time()))
log_path = os.path.dirname(os.getcwd())
log_name = 'test.log'
print(log_name)
logfile = log_name
fh = logging.FileHandler(logfile, mode='a')
fh.setLevel(logging.DEBUG)  # 输出到file的log等级的开关
# 第三步，定义handler的输出格式
formatter = logging.Formatter("%(asctime)s - %(filename)s[line:%(lineno)d] - %(levelname)s: %(message)s")
fh.setFormatter(formatter)
# 第四步，将logger添加到handler里面
logger.addHandler(fh)
# 日志
