python - 更改配置后收到意外的日志消息

Question

以前我用过这种日志模式

log = logging.getLogger(__name__)
log.setLevel(logging.DEBUG)
fh = logging.FileHandler("logs.log", 'w', encoding="utf-8")
formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')
fh.setFormatter(formatter)
log.addHandler(fh)

我的日志文件有这些消息:

2019-08-21 11:08:08,271 - INFO - Started
2019-08-21 11:08:08,271 - INFO - Connecting to Google Sheets...
2019-08-21 11:08:11,857 - INFO - Successfuly connected to Google Sheet
2019-08-21 11:08:11,869 - ERROR - Not found: 'TG'
2019-08-21 11:08:11,869 - DEBUG - Getting values from Sheets...
2019-08-21 11:08:12,452 - DEBUG - Got new event row: "Flex - Flex"
2019-08-21 11:08:12,453 - DEBUG - Done. Values: 
...

它看起来很丑，我把它改成了这样:

logging.basicConfig(
   level = logging.DEBUG,
   format = '%(asctime)s - %(levelname)s - %(message)s',
   filename = 'logs.log', filemode = 'w'
 )
log = logging.getLogger()

现在我的日志文件看起来像那样

我收到一些我没有在我的代码中使用的请求调试日志

如何关闭它？ 我发现这是因为请求模块

Answer 1

来自请求模块的所有日志消息的原因是因为下面的代码，

logging.basicConfig(
   level = logging.DEBUG   # This sets the root logger to DEBUG
 )

logging.basicConfig 更改程序中存在的根记录器的记录器配置

由于您在这里使用了 requests 模块，requests 使用 urllib3 来打印那些调试消息。

修复:

您可以使用您的第一个记录器初始化代码来配置您的记录器，您也可以使用下面的代码，

logging.basicConfig(
   format = '%(asctime)s - %(levelname)s - %(message)s',
   filename = 'logs.log', filemode = 'w'
 )
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)   # Here you are changing the level of your logger alone
