python 使用装饰器并记录log的示例代码

# -*- coding: utf-8 -*-import osimport timeimport loggingimport syslog_dir1=os.path.join(os.path.dirname(os.path.dirname(__file__)),"logs")today = time.strftime('%Y%m%d', time.localtime(time.time()))full_path=os.path.join(log_dir1,today)if not os.path.exists(full_path): os.makedirs(full_path)log_path=os.path.join(full_path,"facebook.log")def get_logger():  # 获取logger实例，如果参数为空则返回root logger  logger = logging.getLogger("facebook")  if not logger.handlers:   # 指定logger输出格式   formatter = logging.Formatter('%(asctime)s %(levelname)-8s: %(message)s')    # 文件日志   file_handler = logging.FileHandler(log_path,encoding="utf8")   file_handler.setFormatter(formatter) # 可以通过setFormatter指定输出格式    # 控制台日志   console_handler = logging.StreamHandler(sys.stdout)   console_handler.formatter = formatter # 也可以直接给formatter赋值    # 为logger添加的日志处理器   logger.addHandler(file_handler)   logger.addHandler(console_handler)    # 指定日志的最低输出级别，默认为WARN级别   logger.setLevel(logging.INFO)  # 添加下面一句，在记录日志之后移除句柄  return logger
