Python日志记录:禁用输出到stdout

Question

我正在尝试使程序仅使用SysLogHandler实例进行日志记录而不使用其他处理程序.我希望它不会记录到任何文件或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)

但是通过这种设置,它继续在运行时将线路吐出到标准输出 python srcipt.py

您有不同的方法:

-set logger.propagate为false.

• 你可以创建自己的游戏流,像这样:

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

并将它交给你的记录器.

logging.StreamHandler(stream=None)
