Question

我有一个python软件包，其中包含一个主脚本（main.py）和另一个模块（apirequests.py）。主脚本调用子模块以发出REST API请求。

对于日志记录，我已经在 init .py：

中的一个函数中启动了一个10KB的旋转日志文件处理程序。

import logging
from logging.handlers import RotatingFileHandler

try:
    from http.client import HTTPConnection  # py3
except ImportError:
    from httplib import HTTPConnection  # py2

def setup_logger(name=__name__, log_file=None, level=logging.INFO):
    formatter = logging.Formatter('%(asctime)s: %(name)s: [%(levelname)s]: %(message)s')
    handler = RotatingFileHandler(log_file, maxBytes=10*1024, backupCount=5)
    handler.setFormatter(formatter)
    logger = logging.getLogger(name)
    logger.setLevel(level)
    logger.addHandler(handler)
    logger.propagate = True

    return logger

我试图将来自main.py和apirequests.py的消息记录到同一日志文件（log.log）中，并将所有HTTP请求消息记录到单独的日志文件（localhost.log）中。

但是每当log.log文件尝试进行翻转时，执行都会中断，因为它试图这样做，而软件包中的模块之一仍在尝试对其进行写操作。

这是 main.py 调用日志记录功能的方式：

logger = setup_logger(__name__, log.log)

logger.info('Program begins') # This goes to Log.log file
.
.
.call apirequests() module's functions
.
.

这是 apirequests.py 调用记录器的方式：

logger1 = setup_logger(__name__, log.log)
logger2 = setup_logger('urllib3', localhost.log, logging.DEBUG)

logger1.info('Start making REST calls')  # # This goes to log.log file
.
.
<make some REST API calls whose logging goes to localhost.log file>
.
.

错误：

  File "C:\Python27\Lib\logging\handlers.py", line 77, in emit
    self.doRollover()
  File "C:\Python27\Lib\logging\handlers.py", line 142, in doRollover
    os.rename(self.baseFilename, dfn)

从多个模块登录到同一日志文件时发生翻转失败
