Python 日志记录:禁用输出到标准输出 [英] Python logging: disable output to stdout

问题描述

我试图让程序只使用 SysLogHandler 实例进行日志记录，而不使用其他处理程序.我希望它不会登录到任何文件或标准输出.

I'm trying to make a program use only the SysLogHandler instance for logging and no other handlers. I expect it to not log to any files or stdout.

    self.logger = logging.getLogger(self.name)

    syslog_handler = logging.handlers.SysLogHandler(
        socktype=socket.AF_UNIX,
        address='/dev/log',
        facility=logging.handlers.SysLogHandler.LOG_LOCAL4,
    )

    # Check if there is a handler attached
    if len(self.logger.handlers) > 0:

        # If there is a handler attached
        # ensure it is a SysLogHandler instance

        handler = self.logger.handlers[0]
        if not (handler.__class__ == logging.handlers.SysLogHandler):
            # If is was something else but a SysLogHandler instance,
            # remove it and attach the syslog_handler

            self.logger.handlers = []
            self.logger.addHandler(syslog_handler)
    else:
        # If no handlers attached,
        # attach syslog_handler

        self.logger.handlers = []
        self.logger.addHandler(syslog_handler)

但是使用此设置，当使用 python srcipt.py

But with this setup it continues to spit lines out to stdout when run with python srcipt.py

推荐答案

你有不同的方法来做到这一点:

You have different ways to do so:

-将 logger.propagate 设置为 false.

-set logger.propagate to false.

• 您可以创建游览自己的流，如下所示:

• you can create tour own stream, like this:

https://docs.python.org/2/library/io.html#io.StringIO

并将其交给您的记录器.

And give it to your logger.

logging.StreamHandler(stream=None)
