python 日志 按日期或大小归档

随着回调的事件与越来越多，如果每个事件都写一个方法，这就显得代码的冗余，所以，今天将日志都归档，分类

事件日志，看情况，我们一般保留10天，至于错误日志，一般不会报错，所以我们按文件的大小进行分类

# 按日期进行分类import loggingimport logging.handlers as handlersclass InfoLog(object):    def __init__(self, file_name):        formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')        self.logHandler = handlers.TimedRotatingFileHandler(file_name, when='D', interval=1, backupCount=10)        self.logHandler.setLevel(logging.INFO)        self.logHandler.setFormatter(formatter)        self.file_name = file_name        self.cons = logging.basicConfig(format='%(asctime)s: %(message)s', level=logging.INFO)    def send_msg(self, msg):        logger = logging.getLogger(self.file_name)        logger.setLevel(logging.INFO)        logger.addHandler(self.logHandler)        logger.info(msg)callback = InfoLog("callback.log")callback.send_msg("33")

# 按大小进行分类import loggingimport logging.handlers as handlersclass ErrLog(object):    def __init__(self, file_name):        formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')        self.errorLogHandler = handlers.RotatingFileHandler(file_name, maxBytes=5000, backupCount=0)        self.errorLogHandler.setLevel(logging.INFO)        self.errorLogHandler.setFormatter(formatter)        self.file_name = file_name        self.cons = logging.basicConfig(format='%(asctime)s: %(message)s', level=logging.INFO)    def send_msg(self, msg):        logger = logging.getLogger(self.file_name)        logger.setLevel(logging.INFO)        logger.addHandler(self.errorLogHandler)        logger.info(msg)err = ErrLog("err.log")err.send_msg("44")

# 对其中出现的参数进行说明# backupCount 备份的数量# filename 文件完整路径# formatter 要使用的日志格式# level 日志级别# interval 增量的频率
