python日志库loguru使用教程封装自定义工具类自定义日志格式化控制台输出和日志写入

loguru的git网址,点我去
先看二次封装loguru后的结果如何.

• 控制台输出

• 日志写入

而默认的输出模式是这样的

我更改了其输出的格式使我们可以利用编辑器快速定位到问题所在
说明:loguru的格式化输出,控制台和日志写入是不同的,分开设置的.


以pycharm为例,我们鼠标选中模块名和方法名,Ctrl+Shift+N 即可在ALL中找到该方法,然后根据行号快速定位到日志出题所在.

下面直接上代码,如何修改控制台日志输出和日期写入的格式

前置条件:

pip install loguru

import sys

from loguru import logger


class MyLogger:
    def __init__(self):
        self.logger = logger
        # 清空所有设置
        self.logger.remove()
        # 添加控制台输出的格式,sys.stdout为输出到屏幕;关于这些配置还需要自定义请移步官网查看相关参数说明
        self.logger.add(sys.stdout,
                        format="{time:YYYYMMDD HH:mm:ss} | "  # 颜色>时间
                               "{process.name} | "  # 进程名
                               "{module}.{function}"  # 模块名.方法名
                               ":{line} | "  # 行号
                               "{level}: "  # 等级
                               "{message}",  # 日志内容
                        )
        # # 输出到文件的格式,2022年4月20日09:18:44 关闭日志输出到文件,这里的add和上面的不冲突,两个add控制两个输出
        # self.logger.add(log_file_path, level='DEBUG',
        #                 format='{time:YYYYMMDD HH:mm:ss} - '
        #                        '{module}.{function}:{line} - {level} -{message}',
        #                 rotation="10 MB")

    def get_logger(self):
        return self.logger


my_logger = MyLogger().get_logger()


def ss():
    my_logger.info(2222222)
    my_logger.debug(2222222)
    my_logger.warning(2222222)
    my_logger.error(2222222)
    my_logger.exception(2222222)


if __name__ == '__main__':
    ss()
