设置控制台脚本中的日志记录 [英] settings up logging in console script

问题描述

我有一个python控制台脚本，我不想修改该源.

I have a python console script, which source I don't want to modify.

但是我想修改由脚本及其库完成的日志记录.

But I want to modify the logging which is done by the script and its libraries.

示例:

• 我希望将错误级别为ERROR的邮件邮寄到[e-mail]
• 我希望忽略文件foo.py的INFO消息.
• 我想在日志消息中包含PID.

该脚本使用此记录器:

import logging
logger=logging.getLogger(__name__)
del(logging)

如果我不想修改控制台脚本的源代码，该如何配置日志记录?

How can I configure the logging, if I don't want to modify the sources of the console script?

推荐答案

您可以使用包装脚本来加载它.在包装器中，根据需要设置日志记录配置(例如logging.basicConfig()或根据需要添加日志记录处理程序)，然后运行脚本. 如果脚本具有主要功能(在脚本中查找if __name__ == "__main__":)，则只需导入文件并运行该功能:

You can load it using a wrapper script. In the wrapper, set the logging configuration as desired (e.g. logging.basicConfig(), or add logging handlers as desired), and then run the script.
If the script has a main function (look for if __name__ == "__main__": in the script), you can simply import the file and run the function:

import sys
import logging
logging.basicConfig(...)
import my_console_script
sys.exit(my_console_script.main())

如果它没有这样的功能，则只需将其导入即可运行其内容(您可以省略sys.exit()调用).

If it doesn't have such a function, then simply importing it will run its contents (you can omit the sys.exit() call).
