如何从Python中的请求模块中完全删除任何日志记录 [英] How can I completely remove any logging from requests module in Python

问题描述

如何在Python中从请求模块中完全删除任何日志记录?我甚至不需要设置关键级别.像这样

How can I completely remove any logging from requests module in Python? I don't need to set even CRITICAL level. Smth like this

import logging
requests_log = logging.getLogger("requests")
requests_log.setLevel(logging.CRITICAL)

但没有任何消息，甚至是严重的.

but without any messages, even CRITICAL.

推荐答案

首先，requests 不记录任何内容；仅requests依赖的urllib3库起作用.该库仅记录INFO和DEBUG级别的消息，因此将日志级别设置为logging.CRITICAL 会禁用所有已经存在的消息

First of all, requests doesn't log anything; only the urllib3 library that requests depends on does. That library only logs messages at INFO and DEBUG levels, so setting the log level to logging.CRITICAL disables all messages already:

urllib3_log = logging.getLogger("urllib3")
urllib3_log.setLevel(logging.CRITICAL)

您还可以仅禁用传播:

logging.getLogger("urllib3").propagate = False

这足以完全禁用urllib3库所做的所有日志记录.

That's enough to completely disable all logging that the urllib3 library does.

urllib3项目已安装 NullHandler() 项目根记录器上的处理程序对象，可确保 lastResort处理程序不会用于未处理的消息，即使传播已被禁用.

The urllib3 project has installed a NullHandler() handler object on the project root logger, which ensures that the lastResort handler is not used for unhandled messages, even when propagation has been disabled.

也就是说，如果您不相信requests的将来版本不会将sys.maxint用作日志级别，而同时又忽略了设置NullHandler()，那么请务必添加您的在项目根记录器对象上拥有NullHandler()，然后在此处禁用传播:

That said, if you don't trust that future versions of requests won't use sys.maxint as a log level, and at the same time neglect to set a NullHandler(), then by all means add your own NullHandler() on the project root logger object, and then disable propagation there:

import logging

requests_log = logging.getLogger("requests")
requests_log.addHandler(logging.NullHandler())
requests_log.propagate = False

现在，requests层次结构中的所有日志记录都将定向到NullHandler()实例，并且propagate设置为False时，日志记录将在此处停止.您可以使用此选项使层次结构中的任何记录器保持静音.

Now all logging within the requests hierarchy will be directed to the NullHandler() instance, and with propagate set to False logging stops there. You can use this to silence any logger in the hierarchy.

我认为这太过分了，到目前为止，没有发布任何requests版本使用日志记录，并且该项目配备了有能力的开发人员，如果他们确实添加了日志记录，则他们不太可能会错误地配置日志记录设置.

In my opinion, that's overkill, no requests release made so far uses logging, and the project is staffed with capable developers that are unlikely to misconfigure the logging setup if they ever did add logging.
