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 logging
    import logging.handlers as handlers
    
    
    class 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 logging
    import logging.handlers as handlers
    
    
    class 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
