# logging模块 ------ 日志 # 为啥写log? # 为了排错 为了做数据分析 操作审计 # 无论想打印日志里面的什么内容,都需要自己写 # basicConfig 进行设置格式 import logging # 输出内容有五个级别 默认 # logging.debug(‘debug message‘) #调试 # logging.info(‘info‘) 信息 # logging.warning(‘warning‘) 警告 # logging.error(‘error‘) 错误 # logging.critical(‘critical‘) 批判性的 # logging.basicConfig函数各参数: # filename:指定日志文件名; # filemode:和file函数意义相同,指定日志文件的打开模式,‘w‘或者‘a‘; # format:指定输出的格式和内容,format可以输出很多有用的信息, # datefmt:指定时间格式,同time.strftime() # # %(levelno)s:打印日志级别的数值 # # %(levelname)s:打印日志级别的名称 # # %(pathname)s:打印当前执行程序的路径,其实就是sys.argv[0] # # %(filename)s:打印当前执行程序名 # # %(funcName)s:打印日志的当前函数 # # %(lineno)d:打印日志的当前行号 # # %(asctime)s:打印日志的时间 # # %(thread)d:打印线程ID # # %(threadName)s:打印线程名称 # # %(process)d:打印进程ID # # %(message)s:打印日志信息 # logging.warning(‘warning message text1‘) # logging.basicConfig( # format=‘%(asctime)s - %(name)s - %(levelname)s[line: %(lineno)d]-%(module)s: %(message)s‘, # datefmt=‘%Y-%M-%d %H:%M:%S %p‘, # #level= logging.DEBUG, # ) # # logging.warning(‘warning message text2‘) # logging.error(‘error message text2‘) # logging.critical(‘cietical message text2‘) # 输出到文件 # logging.basicConfig( # format=‘%(asctime)s - %(name)s - %(levelname)s[line: %(lineno)d]-%(module)s: %(message)s‘, # datefmt=‘%Y-%M-%d %H:%M:%S %p‘, # filename=‘tmp.log‘, # filemode=‘w‘, # level= logging.DEBUG # # ) # # logging.warning(‘warning message text1‘) # logging.error(‘error message text2‘) # logging.critical(‘cietical message text3‘) # 同时输出到屏幕和文件 # fh = logging.FileHandler(‘tmp.log‘,encoding=‘utf-8‘) # fh2 = logging.FileHandler(‘tmp2.log‘,encoding=‘utf-8‘) # # sh = logging.StreamHandler() # logging.basicConfig( # format=‘%(asctime)s - %(name)s - %(levelname)s[line: %(lineno)d]-%(module)s: %(message)s‘, # datefmt=‘%Y-%M-%d %H:%M:%S %p‘, # # level= logging.ERROR, # handlers=[fh,sh,fh2] # ) # # logging.warning(‘warning message text1‘) # logging.error(‘error message text2‘) # logging.critical(‘cietical message text3‘) # 做日志切割 # import time # from logging import handlers # sh = logging.StreamHandler() # rh = handlers.RotatingFileHandler(‘myapp.log‘,maxBytes=1024,backupCount=5) 按照文件大小切割 # fh = handlers.TimedRotatingFileHandler(filename=‘x2.log‘, when=‘s‘, interval=5,encoding=‘utf-8‘) 按照时间切割 # logging.basicConfig( # format=‘%(asctime)s - %(name)s - %(levelname)s[line: %(lineno)d]-%(module)s: %(message)s‘, # datefmt=‘%Y-%M-%d %H:%M:%S %p‘, # # level= logging.DEBUG, # handlers=[fh,rh,sh] # ) # # for i in range(1,100000): # time.sleep(0.1) # logging.error(‘KeyboardInterrupt error %s‘%str(i))
