python实现log日志的示例代码
源代码:
#coding=utf-8 importlogging importos importtime LEVELS={'debug':logging.DEBUG,\ 'info':logging.INFO,\ 'warning':logging.WARNING,\ 'error':logging.ERROR,\ 'critical':logging.CRITICAL,} logger=logging.getLogger() level='default' defcreateFile(filename): path=filename[0:filename.rfind('/')] ifnotos.path.isdir(path): os.makedirs(path) ifnotos.path.isfile(filename): #创建并打开一个新文件 fd=open(filename,mode='w',encoding='utf-8') fd.close() classMyLog: log_filename='E:/quality/it/pyrequest-master/log/itest.log' err_filename='E:/quality/it/pyrequest-master/log/err.log' dateformat='%Y-%m-%d%H:%M:%S' logger.setLevel(LEVELS.get(level,logging.NOTSET)) createFile(log_filename) createFile(err_filename) #注意文件内容写入时编码格式指定 handler=logging.FileHandler(log_filename,encoding='utf-8') errhandler=logging.FileHandler(err_filename,encoding='utf-8') @staticmethod #静态方法 defdebug(log_message): setHandler('debug') logger.debug("[DEBUG"+getCurrentTime()+"]"+log_message) removerhandler('debug') @staticmethod definfo(log_message): setHandler('info') logger.info("[INFO"+getCurrentTime()+"]"+log_message) removerhandler('info') @staticmethod defwarning(log_message): setHandler('warning') logger.warning("[WARNING"+getCurrentTime()+"]"+log_message) removerhandler('warning') @staticmethod deferror(log_message): setHandler('error') logger.error("[ERROR"+getCurrentTime()+"]"+log_message) removerhandler('error') @staticmethod defcritical(log_message): setHandler('critical') logger.critical("[CRITICAL"+getCurrentTime()+"]"+log_message) removerhandler('critical') #logger可以看做是一个记录日志的人,对于记录的每个日志,他需要有一套规则,比如记录的格式(formatter), #等级(level)等等,这个规则就是handler。使用logger.addHandler(handler)添加多个规则, #就可以让一个logger记录多个日志。 defsetHandler(level): iflevel=='error': logger.addHandler(MyLog.errhandler) #handler=logging.FileHandler(log_filename) #把logger添加上handler logger.addHandler(MyLog.handler) defremoverhandler(level): iflevel=='error': logger.removeHandler(MyLog.errhandler) logger.removeHandler(MyLog.handler) defgetCurrentTime(): returntime.strftime(MyLog.dateformat,time.localtime(time.time())) if__name__=="__main__": MyLog.debug("Thisisdebugmessage") MyLog.info("Thisisinfomessage") MyLog.warning("Thisiswarningmessage") MyLog.error("Thisiserrormessage") MyLog.critical("Thisiscriticalmessage")
