The following is a sample code for python to implement log log. It has a good reference value and I hope it will be helpful to everyone. Let’s take a look together
# coding=utf-8 import logging import os import time LEVELS={'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")
