[Python知识库]Python使用yaml配置logging日志+根据当前时间创建日志名称

1、用yaml配置文件来配置logging日志
2、以当前日期（ex.年月日时分）作为日志文件名

代码目录结构如下：

py
  |-- config
    |--config.yaml
  |--logger.py

# config.yaml
version: 1
disable_existing_loggers: False

formatters:
    simple:
        format: '[%(asctime)s] [%(levelname)s] %(message)s'
    upgrade:
        format: "[%(asctime)s] [%(filename)s] [Pid:%(process)d] [%(levelname)s] %(message)s"
handlers:
    console:
        class: logging.StreamHandler
        level: DEBUG
        formatter: simple
        stream: ext://sys.stdout
    file_handler:
        class: logging.handlers.RotatingFileHandler
        level: DEBUG
        formatter: upgrade
        filename: ./logs/all_log.log
        maxBytes: 10485760 # 10MB
        backupCount: 50 #保留50个log文件
        encoding: utf8
root:
    level: DEBUG
    handlers: [console, file_handler]

# logger.py
# _*_ coding: utf-8 _*_
import logging
import os.path
import time
import yaml
import logging.config

project_path = 'py'  #定义项目目录

class Logger(object):
    def __init__(self):
        # 获取当前文件所在目录路径
        current_path=os.path.dirname(os.path.abspath(project_path))
        #指定分隔符对字符串进行切片  
        path1=current_path.split(project_path)  
        path2=[path1[0], project_path]
        # 日志目录路径
        log_path=''.join(path2) + '/logs/'
        # 配置文件路径
        config_path=''.join(path2) + '/config/config.yaml'

        # 获取当前时间(年月日)作为下级目录名称
        dir_time = time.strftime('%Y%m%d', time.localtime(time.time())) 
        # 获取当前时间作为日志文件名称
        current_time=time.strftime('%Y%m%d%H%M',time.localtime(time.time() )) 
        # 定义日志文件路径以及名称
        log_name = log_path  + dir_time + '/' + current_time + '.log'  
            
        if not os.path.exists(log_path + dir_time):
            os.makedirs(log_path + dir_time)

        try:
            with open(file=config_path, mode='r', encoding="utf-8")as file:
                logging_yaml = yaml.load(stream=file, Loader=yaml.FullLoader)
                logging_yaml['handlers']['file_handler']['filename'] = log_name
            # 配置logging日志
            logging.config.dictConfig(config=logging_yaml)
            # 创建一个logger(初始化logger)
            self.log = logging.getLogger()
        except Exception as e:
            print(e)

    # 日志接口
    def debug(cls, msg):
        cls.log.debug(msg)
        return

    def info(cls,msg):
        cls.log.info(msg)
        return

    def error(cls, msg):
        cls.log.error(msg)
        return


if __name__ == '__main__':
    logger = Logger()
    logger.info('This is info')
    logger.debug('This is debug')
    logger.error('This is error')
