为什么我在记录日志时 FastAPI 不创建日志文件

这是我使用的代码

from fastapi.logger import logger as fastapi_logger
from logging.handlers import RotatingFileHandler
import logging

formatter = logging.Formatter(
        "[%(asctime)s.%(msecs)03d] %(levelname)s [%(thread)d] - %(message)s", "%Y-%m-%d %H:%M:%S")
handler = RotatingFileHandler('logfile.log', backupCount=0)
logging.getLogger("fastapi")
fastapi_logger.addHandler(handler)
handler.setFormatter(formatter)

fastapi_logger.info('****************** Starting Server *****************')

与 Flask 不同，文件“logfie.log”不会自动生成。还有其他配置吗？

我想使用 Flask-talisman 来保护我的应用程序

我有一个带有“date_created”列的熊猫数据框

该列的格式为 YYYY-MM-DD。例如：2017-10-05

我想按 MM/YYYY 分组

我用过这个，但它包括 DD

frame['date_created'].value_counts() 

无论如何使用YYYY和MM查询它
