yaml文件是python中比较常用的一种配置文件

yaml文件：

version: 1
# 将信息传播到配置文件的根日志记录器中
disable-exiting-loggers: False
formatters:
  simple:
    format: "%(asctime)s - %(filename)s - %(name)s - %(levelname)s - %(message)s"

handlers:
  console:
    class: logging.StreamHandler
    level: DEBUG
    formatter: simple
    stream: ext://sys.stdout

  info_file_handler:
    class: logging.handlers.RotatingFileHandler
    level: DEBUG
    formatter: simple
    filename: ../log/info.log
    maxBytes: 10485760 # 10MB
    backupCount: 20
    encoding: utf8

#  error_file_handler:
#    class: logging.handlers.RotatingFileHandler
#    level: ERROR
#    formatter: simple
#    filename: ../log/info.log
#    maxBytes: 10485760 # 10MB
#    backupCount: 20
#    encoding: utf8

#loggers:
#  normal:
#    level: ERROR
#    handlers: [ console ]

root:
  level: DEBUG
  handlers: [ console, info_file_handler ]

python调用

import logging.config
import time

import yaml
from utils.file_util import FileUtil


class LogUtil(object):
    def __init__(self):
        self.root_path = FileUtil().get_root_path()
        with open(file=self.root_path + 'config\\yaml\\log.yaml', mode='r', encoding='utf-8') as f:
            self.log_yaml = yaml.load(stream=f, Loader=yaml.FullLoader)
            # 根据日期生成文件名称
            file = time.strftime('%Y%m%d', time.localtime(time.time())) + '.log'
            self.log_yaml['handlers']['info_file_handler']['filename'] = FileUtil().get_root_path() + 'log\\' + file

    def m_get_logger(self):
        logging.config.dictConfig(self.log_yaml)
        m_log = logging.getLogger()
        return m_log


if __name__ == '__main__':
    LogUtil().m_get_logger().debug('debug')
    LogUtil().m_get_logger().error('error')
    LogUtil().m_get_logger().critical('critical')

运行结果

python通过yaml文件配置日志_配置文件
