[Python] 纯文本查看 复制代码 6.51 logging模块的四类对象
logger:负责产生日志
logger1=logging.getLogger('xxx')
filter:过滤日志(不常用)
handler:控制日志打印到文件or终端
fh1=logging.FileHandler(filename='a1.log',encoding='utf-8')
fh2=logging.FileHandler(filename='a2.log',encoding='utf-8')
sh=logging.StreamHandler()
formatter:控制日志的格式
formatter1=logging.Formatter(
fmt='%(asctime)s - %(name)s - %(levelname)s -%(module)s: %(message)s',
datefmt='%Y-%m-%d %H:%M:%S %p',
)
formatter2=logging.Formatter(fmt='%(asctime)s - %(message)s',)
logger ---->多个file handler <----多个formatter
绑定关系:
1.为logger1对象绑定handler:
logger1.addHandler(fh1)
logger1.addHandler(fh2)
logger1.addHandler(sh)
2.为handler对象绑定日志格式
fh1.setFormatter(formatter1)
fh2.setFormatter(formatter1)
sh.setFormatter(formatter2)
设定日志级别: 两层关卡,必须都通过,日志才能正常记录
logger1.setLevel(10)
fh1.setLevel(10)
fh2.setLevel(10)
sh.setLevel(10)
#调用logger1对象下的方法,产生日志,然后交给不同的handler,控制日志记录到不同的地方
logger1.debug('调试信息') #调用logger1,产生日志
日志的继承
import logging
logger1=logging.getLogger('xxx')
logger2=logging.getLogger('xxx.son')
logger3=logging.getLogger('xxx.son.grandson')
sh=logging.StreamHandler()
formatter2=logging.Formatter(fmt='%(asctime)s - %(message)s',)
sh.setFormatter(formatter2)
logger1.addHandler(sh)
logger2.addHandler(sh)
logger3.addHandler(sh)
logger1.setLevel(10)
logger2.setLevel(10)
logger3.setLevel(10)
sh.setLevel(10)
logger1.debug('测试。。。。')
logger2.debug('测试。。。。')
logger3.debug('测试。。。。')
