python 使用装饰器并记录log的示例代码

# -*- coding: utf-8 -*-
import os
import time
import logging
import sys
log_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
