bae扩展服务日志等级区分

CRITICAL = 50
FATAL = CRITICAL
ERROR = 40
WARNING = 30
WARN = WARNING
INFO = 20
DEBUG = 10
NOTSET = 0

_levelNames = {
CRITICAL : ‘CRITICAL’,
ERROR : ‘ERROR’,
WARNING : ‘WARNING’,
INFO : ‘INFO’,
DEBUG : ‘DEBUG’,
NOTSET : ‘NOTSET’,
‘CRITICAL’ : CRITICAL,
‘ERROR’ : ERROR,
‘WARN’ : WARNING,
‘WARNING’ : WARNING,
‘INFO’ : INFO,
‘DEBUG’ : DEBUG,
‘NOTSET’ : NOTSET,
}

调试了好久，debug的信息死活不给输出，看源码没看懂，各种等级都试过了都不行
