如何在python日志消息中将“levelname”重命名为“level”?

我有一个python日志记录配置,如下所示:

LOGGING_CONFIG:
    version: 1
    formatters:
        human:
            class: logging.Formatter
            format: '[%(asctime)s]:[%(levelname)s]: %(message)s'
        json:
            class: pythonjsonlogger.jsonlogger.JsonFormatter
            format: '%(asctime)s %(levelname)s %(message)s'
    handlers:
        console:
            class: logging.StreamHandler
            level: DEBUG
            formatter: json  # change this to 'human' when you run it locally, json in production
        file:
            class: logging.FileHandler
            filename: logfile.log
            level: DEBUG
            formatter: json
    root:  # Logging for 3rd party stuff
        level: INFO
        handlers:
            - console
            - file
    project_name:  # Logging this module
        level: DEBUG
        handlers:
            - console
            - file

对于另一个系统,我需要结构化日志记录有一些固定的名称。一个例子是它不应该 levelname 但是 level . 如何重命名日志字段?

我所拥有的:

{"asctime": "2018-10-22 14:50:19,923", "levelname": "info", "message": "foobar"}

我想要的是:

{"asctime": "2018-10-22 14:50:19,923", "level": "info", "message": "foobar"}
