Python基于yaml文件配置logging日志过程解析

with open(file="./loggingconfigyaml.yaml", mode='r', encoding="utf-8")as file:
    logging_yaml = yaml.load(stream=file, Loader=yaml.FullLoader)
    # print(logging_yaml)
    # 配置logging日志：主要从文件中读取handler的配置、formatter（格式化日志样式）、logger记录器的配置
    logging.config.dictConfig(config=logging_yaml)
  # 获取根记录器：配置信息从yaml文件中获取
  root = logging.getLogger()
  # 子记录器的名字与配置文件中loggers字段内的保持一致
  my_module = logging.getLogger("my_module")
  print("rootlogger:", root.handlers)
  print("selflogger", my_module.handlers)
  # print("子记录器与根记录器的handler是否相同：", root.handlers[0] == my_module.handlers[0])
  my_module.error("DUBUG")
  root.info("INFO")
  root.error('ERROR')
  root.debug("rootDEBUG")
