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'
,)

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(

logging.StreamHandler()
formatter2

logging.Formatter(fmt
