记录一种日志封装

logger.py

import os
import logging
 
 
class AppLogger:
    def __init__(self, name, level=logging.DEBUG, stdout=False, tofile=None):
        # 创建一个logger
        self.logger = logging.Logger(name)
        self.logger.setLevel(level)
 
        # 定义日志输出格式
        formatter = logging.Formatter('%(asctime)s [%(levelname)5s] %(filename)s:%(lineno)d %(message)s')
 
        if tofile:
            # 创建一个handler，用于写入日志文件
            log_path = os.path.join(tofile)
            fh = logging.FileHandler(log_path)
            fh.setFormatter(formatter)
            self.logger.addHandler(fh)
 
        if stdout:
            # 再创建一个handler，用于输出到控制台
            ch = logging.StreamHandler()
            ch.setFormatter(formatter)
            self.logger.addHandler(ch)
 
    def getlog(self):
        return self.logger
 
 
if __name__ == '__main__':
    applog = AppLogger('applog', stdout=True).getlog()
    applog.info('this is a info log')
