对python日志logging进行类封装

python logging模块的四大组件：日志器、处理器、过滤器、格式器。

class FrameLog:
    def __init__(self):
        #创建日志器
        self.logger = logging.getLogger()

        # 设置日志路径以及日志文件名
        self.log_time = time.strftime('%Y_%m_%d %H_%M_%S')
        self.log_path = project_path() + '\Logs/'
        self.log_name = self.log_path + self.log_time + 'log.log'
        self.format = logging.Formatter(fmt='%(asctime)s %(filename)s %(lineno)d %(levelname)s %(message)s', datefmt='%Y-%m-%d %H:%M:%S %a')

    def set_filehandler(self):
        # 创建文件处理器

        # 处理器添加格式器
        self.file_handler.setFormatter(self.format)
        # 日志器添加文件处理器
        self.logger.addHandler(self.file_handler)
        # 关闭打开的文件
        self.file_handler.close()

    log.critical('严重级别')
