1.日志过滤
import logging
class IgnoreFilter(logging.Filter):
def filter(self,record):
return "girl" not in record.getMessage() #如果girl不在record里，则返回True
# 1.生成logger对象
logger = logging.getLogger("130")
logger.setLevel(logging.DEBUG) #不设置级别，默认最低级别是warning。
logger.addFilter(IgnoreFilter())
# 2.生成handler对象
# 把handler对象绑定到logger
ch = logging.StreamHandler()
# ch.setLevel(logging.DEBUG) #对屏幕和文件分别设置级别
fh = logging.FileHandler("130.log")
# fh.setLevel(logging.ERROR)
logger.addHandler(ch)
logger.addHandler(fh)
# 3.生成formatter对象
# 把formatter对象绑定到handler
file_formatter = logging.Formatter("%(asctime)s %(name)s %(levelname)s %(message)s")
console_formatter = logging.Formatter("%(asctime)s %(name)s %(levelname)s %(lineno)s %(message)s")
ch.setFormatter(console_formatter)
fh.setFormatter(file_formatter)
logger.debug("miss eat")
logger.warning("hello girl")
2.日志截断
2.1 根据日志大小截断
maxBytes 最大字节 backupCount 文件最多存在的个数。
from loggign import handlers
fh = handlers.RotatingFileHandler("130.log",maxBytes=10,backupCount = 5)
2.2 按照时间间隔来截断日志，最多生成五个
when 时间单位，interval 时间间隔。
fh = handlers.TimedRotatingFileHandler("130.log",when = "s",interval = 5,backupCount = 5)
