Question

我有一个记录器，如果在调用logger.debug时未提供log_line，则只会添加log_line

class UrlLogger(logging.Logger):
    def _log(self, level, msg, args, exc_info=None, extra=None):
        if extra is None:
            extra = {'log_line':' '}
        super(UrlLogger, self)._log(level, msg, args, exc_info, extra)

我大约需要添加20个不同的模块

logging.setLoggerClass(UrlLogger)

如何在设置中将此设置为默认值？

我的设置当前如下所示：

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'verbose': {
            'format': '%(levelname)s %(name)s %(asctime)s %(module)s %(process)d %(thread)d %(pathname)s@%(lineno)s: %(message)s'
        },
        'simple': {
            'format': '[%(levelname)8s] [%(asctime)s] %(module)10s/%(filename)s:%(log_line)s - %(message)s',
            'datefmt': '%d-%m-%Y %H:%M:%S'
        },
    },

    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
            'level': LOG_LEVEL,
            'formatter': 'simple'
        },
    },
    'loggers': {
        '': {
            'level': LOG_LEVEL,
            'handlers': ['console'],
            'class': ['UrlLogger'],
    },

如您所见，我尝试在此处进行设置，但由于我仍然遇到错误，因此我认为这不起作用。

Message: 'Not Found: %s'

--- Logging error ---

    return fmt.format(record)

    s = self.formatMessage(record)

    return self._style.format(record)
  File "/usr/local/lib/python3.6/logging/__init__.py", line 391, in format
    return self._fmt % record.__dict__
KeyError: 'log_line'

当前端对django后端进行失败的API调用（错误的uri）时，会发生此错误。我以为失败的api调用会在不使用我的UrlLogger的情况下记录错误（否则，除非Logger类中存在错误，否则不会出现关键错误）。

我在这里做什么错了？
