# coding=utf-8import loggingimport osimport timeLEVELS={'debug':logging.DEBUG,\  'info':logging.INFO,\  'warning':logging.WARNING,\  'error':logging.ERROR,\  'critical':logging.CRITICAL,}  logger=logging.getLogger()level='default'def createFile(filename): path=filename[0:filename.rfind('/')] if not os.path.isdir(path):  os.makedirs(path) if not os.path.isfile(filename):#创建并打开一个新文件  fd = open(filename,mode='w',encoding='utf-8')  fd.close()class MyLog: 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 def debug(log_message):  setHandler('debug')  logger.debug("[DEBUG "+getCurrentTime()+"]"+log_message)  removerhandler('debug') @staticmethod def info(log_message):  setHandler('info')  logger.info("[INFO "+getCurrentTime()+"]"+log_message)  removerhandler('info')  @staticmethod def warning(log_message):  setHandler('warning')  logger.warning("[WARNING "+getCurrentTime()+"]"+log_message)  removerhandler('warning') @staticmethod def error(log_message):  setHandler('error')  logger.error("[ERROR "+getCurrentTime()+"]"+log_message)  removerhandler('error') @staticmethod def critical(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。def setHandler(level): if level=='error':  logger.addHandler(MyLog.errhandler) #handler=logging.FileHandler(log_filename) #把logger添加上handler logger.addHandler(MyLog.handler)def removerhandler(level): if level=='error':  logger.removeHandler(MyLog.errhandler) logger.removeHandler(MyLog.handler)def getCurrentTime(): return time.strftime(MyLog.dateformat,time.localtime(time.time()))if __name__=="__main__": MyLog.debug("This is debug message") MyLog.info("This is info message") MyLog.warning("This is warning message") MyLog.error("This is error message") MyLog.critical("This is critical message")
