问题描述
我有这个python代码:
I have this python code:
import logging
LOGGER = logging.getLogger(__name__)
LOGGER.info('test')
它没有被写入控制台，所以该记录在哪里?
It does not get written to the console, so where does this get logged?
推荐答案
由于您未配置任何日志记录处理程序，因此该记录不会在任何地方记录.如果未配置处理程序，则日志事件将消失.如果未配置任何处理程序，则如果看到WARNING或更高级别的事件，但您的事件只是INFO级别，则根记录程序会自动添加一个处理程序.
This does not get logged anywhere, because you did not configure any logging handlers. Without a handler configured, the log event goes nowhere. When there are no handlers configured, the root logger gets a handler automatically added if an event at WARNING or above is seen, but your event was just at INFO level.
如果您之前放置过这样的行，那么您将看到它记录到终端:
If you put a line like this before, then you will see it logged to terminal:
logging.basicConfig(level=logging.INFO)
如果没有另外指定，基本配置将在sys.stderr上添加StreamHandler文字.
Basic config will add a StreamHandler writing to sys.stderr if you don't specify otherwise.
