记录处理程序为空-为什么记录TimeRoatingFileHandler不起作用 [英] Logging Handlers Empty - Why Logging TimeRoatingFileHandler doesn't work

问题描述

因此，我执行logging.config.fileConfig来从具有控制台和文件处理程序的文件配置中设置日志记录.然后，我执行logging.getLogger(name)来获取记录器和日志.在某些时候，我想更改文件处理程序的文件名，即日志旋转(由于Windows平台存在一些问题，我无法使用时间旋转器)，因此我将其称为logger.handlers-它显示了一个空列表，因此我无法关闭它们!!但是，当我逐步通过调试器时，它显然不是空的(当然，如果没有它，我将无法正确登录)

So I do logging.config.fileConfig to setup my logging from a file config that has console and file handler. Then I do logging.getLogger(name) to get my logger and log. At certain times I want the filehandler's filename to change i.e. log rotate (I can't use time rotator because of some issues with Windows platform) so to do that I call logger.handlers - it shows an empty list, so I cant close them!! However when I step through the debugger, its clearly not empty (well of course without it I wouldn't be able to log right)

不知道这是怎么回事，我缺少任何陷阱吗?

Not sure whats going on here, any gotchas that I'm missing?

感谢任何帮助.谢谢.

推荐答案

似乎您需要正确获取root记录器:

It seems you need to correctly get the root logger:

logger = logging.getLogger(__name__)
handlers = logger.handlers[:]
print('module {}'.format(handlers))
print('module {}'.format(logger.hasHandlers()))

logger = logging.getLogger('root')
handlers = logger.handlers[:]
print('root {}'.format(handlers))
print('root {}'.format(logger.hasHandlers()))

logger = logging.getLogger()
handlers = logger.handlers[:]
print('blank {}'.format(handlers))
print('blank {}'.format(logger.hasHandlers()))

输出:

模块[]

module []

模块True

根[]

为True的

空白[<logging.handlers.RotatingFileHandler object at 0x108d82898>, <logging.StreamHandler object at 0x108d826d8>]

blank [<logging.handlers.RotatingFileHandler object at 0x108d82898>, <logging.StreamHandler object at 0x108d826d8>]

空白为真
