Python的log

关键代码

调用方：

 from Logger import MyLogger
 import logging
 import sys, os

 def getLogger():
     # get the file name
     fileUrl = sys.argv[0]
     filepath, tmpfilename = os.path.split(fileUrl)
     shotname, extension = os.path.splitext(tmpfilename)

     # get the logger object
     logger = MyLogger(logname='log.txt', loglevel=1, logger=shotname).getlog()
     return logger

 logger =getLogger()
 logger.debug("Hoory, show!")

Logger.py

 #开发一个日志系统， 既要把日志输出到控制台， 还要写入日志文件
 import logging

 class MyLogger():
     format_dict = {
         1 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s'),
         2 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s'),
         3 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s'),
         4 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s'),
         5 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
     }

     def __init__(self, logname, loglevel, logger):
         '''
            指定保存日志的文件路径，日志级别，以及调用文件
            将日志存入到指定的文件中
         '''

         # 创建一个logger
         self.logger = logging.getLogger(logger)
         self.logger.setLevel(logging.DEBUG)

         # 创建一个handler，用于写入日志文件
         fh = logging.FileHandler(logname)
         fh.setLevel(logging.DEBUG)

         # 再创建一个handler，用于输出到控制台
         ch = logging.StreamHandler()
         ch.setLevel(logging.DEBUG)

         # 定义handler的输出格式
         formatter = logging.Formatter('%(asctime)s %(name)s %(thread)d %(levelname)s %(message)s')
         fh.setFormatter(formatter)
         ch.setFormatter(formatter)

         # only first time need to add the handler
         if(self.logger.hasHandlers() == False):
             self.logger.addHandler(fh)
             self.logger.addHandler(ch)

     def getlog(self):
         return self.logger

Logger相关属性

可以通过下面的代码来进行设置（基本上不需要这么设置，因为通过getlogger()获取的logger对象并没有集成root的相关配置）：

 logging.basicConfig(filename="log2.txt", level=logging.WARNING)
