Python 记录到配置文件中初始化的 MemoryHandler

Question

我正在尝试将 python MemoryHandler 添加到日志记录配置文件中。我正在使用与之前工作的文件处理程序类似的结构。我对收到的错误有点困惑，并且无法弄清楚我缺少什么才能将日志记录保存到内存中。下面包含了必要的信息。我们将不胜感激。

log_settings.conf

[loggers]
keys=root

[handlers]
keys=memHandler, consoleHandler

[formatters]
keys=fileFormatter, consoleFormatter

[logger_root]
level=DEBUG
handlers=memHandler, consoleHandler

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

[handler_memHandler]
class=handlers.MemoryHandler
formatter=fileFormatter
args=(10, DEBUG, '%(logfilename)s')

[formatter_fileFormatter]
format=[%(asctime)s] [%(levelname)8s] --- (%(filename)15s:%(lineno)4s) %(message)s
datefmt=%Y-%m-%d %H:%M:%S

[formatter_consoleFormatter]
format=%(message)s

build.py

logging.config.fileConfig('../scripts/logging/log_settings.conf', defaults={'logfilename': '../scripts/logging/log.log'})
logging.info('Starting the FGPA build script')

改用此配置文件:

[loggers]
keys=root

[handlers]
keys=memHandler, consoleHandler

[formatters]
keys=fileFormatter, consoleFormatter

[logger_root]
level=DEBUG
handlers=memHandler

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

[handler_memHandler]
class=handlers.MemoryHandler
formatter=fileFormatter
args=(10, DEBUG)
target=consoleHandler

[formatter_fileFormatter]
format=[%(asctime)s] [%(levelname)8s] --- (%(filename)15s:%(lineno)4s) %(message)s
datefmt=%Y-%m-%d %H:%M:%S

[formatter_consoleFormatter]
format=%(message)s

请注意，您不应将 consoleHandler 包含在根记录器的处理程序列表中。此外，您需要使用 target= 行设置目标，并且它需要引用目标处理程序的键。使用以下内容进行配置:

logging.config.fileConfig('logging.ini')
