更改密钥＆＃x27; python json logger中的名称

Question

我想在我的 python json logger 中更改键的名称：

import logging
from pythonjsonlogger import jsonlogger

def main() -> None:

    logger = logging.getLogger("myLovelyLogger")
    logger.warning("something terrible happened")

if __name__ == "__main__":

    logger = logging.getLogger("myLovelyLogger")
    handler = logging.StreamHandler()
    handler.setLevel(logging.INFO)

    formatter = jsonlogger.JsonFormatter(
        fmt="%(asctime)s %(name)s %(levelname)s %(message)s",
        datefmt="%d/%m/%y[ %H:%M:%S ]",
        json_indent=4
    )

    handler.setFormatter(formatter)
    logger.addHandler(handler)

    main()

当我运行它时，一切都很好，我只想更改一些钥匙的名字：

$ python3 main.py
{
    "asctime": "29/06/22[ 13:44:55 ]", # <--- change "asctime" to "time"
    "name": "myLovelyLogger",
    "levelname": "WARNING",            # <--- change "levelname" to "level"
    "message": "something terrible happened"
}

我该如何实现？

Answer 1

显然，我错过了此选项 在文档中。

    formatter = jsonlogger.JsonFormatter(
        fmt="%(asctime)s %(name)s %(levelname)s %(message)s",
        rename_fields={"asctime": "time", "levelname": "level"}, # <--- added this line
        datefmt="%d/%m/%y[ %H:%M:%S ]",
        json_indent=4
    )

然后，我得到所需的结果
