python 中logger setlevel没有生效

在logging中，Logger's level 的默认等级为warning

所以虽然在handler中setlervel了，Logger's level 和Handler's Level 但是level取较高的那个（待校验）

所以日志的level 为warning

解决此问题可以采用

logging.root.setLevel(logging.NOTSET)

完整源码如下图：

import logging


class loggerr(object):
    def __init__(self,logger):
        self.logger = logging.getLogger(logger)
        self.fmt=logging.Formatter('%(asctime)s - %(name)s - %(levelname)s -%(message)s ')
        logging.root.setLevel(logging.NOTSET)
        #logging.basicConfig(level=logging.NOTSET)


    def getlog(self):

        ch=logging.StreamHandler()
        sh=logging.FileHandler('log1.log')

        ch.setFormatter(self.fmt)
        sh.setFormatter(self.fmt)

        ch.setLevel(logging.INFO)
        sh.setLevel(logging.INFO)

        self.logger.addHandler(ch)
        self.logger.addHandler(sh)
        return self.logger

if __name__ == '__main__':
    mylog=loggerr('mylog').getlog()
    mylog.info('infolog')
    mylog.debug('debuglog')
    mylog.warning('warninglog')
    mylog.error('errorlog')
