改进python tornado中的日志记录方法

Question

我正在尝试在函数中记录操作，并且我编写了以下函数来根据响应类型（即信息、错误、调试和警告）记录对不同文件的响应。

logging.basicConfig(filename='indivi_service.log',
                    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s' )
def setup_logger(logger_name, log_file, level=logging.DEBUG):
    l = logging.getLogger(logger_name)
    formatter = logging.Formatter()
    fileHandler = logging.FileHandler(log_file)
    fileHandler.setFormatter(formatter)
    handler = TimedRotatingFileHandler(logger_name,
                               when="d",
                               interval=1,
                               backupCount=100)


l.setLevel(level)
l.addHandler(fileHandler)
l.addHandler(handler)


setup_logger('debug', r'debug')
setup_logger('error', r'error')
setup_logger('warning', r'warning')
setup_logger('info', r'info')
debug = logging.getLogger('debug')
error = logging.getLogger('error')
warning = logging.getLogger('warning')
info = logging.getLogger('info')


class Info(APIHandler):
    @gen.coroutine
    def post(self):
        req = json.loads(self.request.body)
        resp, content = client(item_id=req['item_id'])
        debug.debug(content)
        info.info(hello world)
        warning.warn('warning message')
        error.error('error message')

我面临的问题是每次调用函数时都会打印两次响应。

例如： 信息日志

hello world hello world

谁能告诉我为什么会这样。所有日志文件都是这种情况。

谢谢

尝试：

import logging
import logging.handlers

logging.basicConfig(filename='indivi_service.log',
                    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s' )
def setup_logger(logger_name, log_file, level=logging.DEBUG):
    l = logging.getLogger(logger_name)
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    handler = logging.handlers.TimedRotatingFileHandler(str(log_file)+'.log', when="d", interval=1, backupCount=100)
    handler.setFormatter(formatter)

    l.setLevel(level)
    l.addHandler(handler)


setup_logger('debug', r'debug')
setup_logger('error', r'error')
setup_logger('warning', r'warning')
setup_logger('info', r'info')
debug = logging.getLogger('debug')
error = logging.getLogger('error')
warning = logging.getLogger('warning')
info = logging.getLogger('info')


if __name__ == "__main__":
    info.info('hello world')
    error.info('hello world')

运行此脚本后，文件 info.log 有一个“hello world”，而error.log 也只有一个“hello world”。
