使用ptb进行Python日志记录：同一行记录了两次，但只添加了一个处理程序 python:3.6.6 python电报机器人：10.0.2

我有这个问题：我已经定义了一个带有SMTPHandler、timedrotationfilehandler和StreamHandler的python记录器

StreamHandler工作得很好，但当我尝试从python telegram bot处理程序使用它时，该行在标准输出上以两种不同的格式打印了两次，我无法找到如何避免一种格式并保留另一种格式（定时格式）

我已经发现了原因。添加带有CallbackQueryHandler的ConversationHandler时，启动时会显示此消息

WARNING:root:If 'per_message=False', 'CallbackQueryHandler' will not be tracked for every message.

然后每次都会出现未清除的日志行

下面的代码是log_config.py。我还添加了用于测试my_main_file.py和作为多行注释的当前输出的示例代码

config/log\u config.py：

telegram.ext.ConversationHandler

包括几个使用

logging.warning

而不是他们可能应该使用的

self.logger

记录器的日志调用，例如：

logging.warning

和其他模块级日志便利函数调用，如果根日志记录器上没有处理程序，则会向根日志记录器添加处理程序。该处理程序负责处理不需要的数据

INFO:__main__:HELP!

记录输出

使用

logging.warning

而不是

self.logger.warning

可能会被认为是python电报机器人的一个bug。我在他们的网站上看不到关于它的公开问题，所以你可能想提交一份bug报告

同时，或者如果python telegram bot开发人员认为行为正常，则可以向根日志记录器添加null处理程序，以防止

basicConfig

添加自己的处理程序。这必须在创建

ConversationHandler

之前完成，以抢占

basicConfig

：

logging.getLogger().addHandler(logging.NullHandler())

在剥离代码时，请确保剥离的表单在运行时仍会复制错误。对不起。你说得对。当使用来自另一个文件的函数时，它会这样做，但我试图简化所有内容以包括在这里，但没有测试它。我正在编辑。我修改了它。我做得再简单不过了。你用的是什么python电报机器人版本？10.0.2和python是3.6.6
