如何使用 python 的 fileConfig 进行日志记录并配置日志文件文件名

问题描述

我有一个用于记录到控制台的日志配置文件和一个具有不同格式和级别的文件.在我的 python 脚本中，我可以加载这个配置，基本上控制台和文件输出都可以.

I have a logging configuration file for logging to console and a file with different formats and levels. In my python script I can load this configuration and basically console and file output are ok.

我在config文件中设置文件名如下图.

I set the file name in the config file as shown below.

是否可以在 python 脚本本身中设置该文件名?

Is it possible to set that file name in the python script itself?

python 代码:

# set up logging
logging.config.fileConfig(loginipath)
logger = logging.getLogger('sLogger')

# log something
logger.debug('debug message')
logger.info('info message')
logger.warn('warn message')
logger.error('error message')
logger.critical('critical message')

日志记录配置文件:

[loggers]
keys=root,sLogger

[handlers]
keys=consoleHandler,fileHandler

[formatters]
keys=fileFormatter,consoleFormatter

[logger_root]
level=DEBUG
handlers=consoleHandler

[logger_sLogger]
level=DEBUG
handlers=consoleHandler,fileHandler
qualname=sLogger
propagate=0

[handler_consoleHandler]
class=StreamHandler
level=WARNING
formatter=consoleFormatter
args=(sys.stdout,)

[handler_fileHandler]
class=FileHandler
level=DEBUG
formatter=fileFormatter
args=('logfile.log',)

[formatter_fileFormatter]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
datefmt=

[formatter_consoleFormatter]
format=%(levelname)s - %(message)s
datefmt=

推荐答案

像这样改变你的 handler_fileHandler 部分:

Change your handler_fileHandler section like so:

[handler_fileHandler]
class=FileHandler
level=DEBUG
formatter=fileFormatter
args=('%(logfilename)s',)

然后在 fileConfig 调用中添加一个 defaults 参数

and then add a defaults argument to the fileConfig call

logging.config.fileConfig(loginipath, defaults={'logfilename': '/var/log/mylog.log'})
