python 日志模块

在自己的项目根路径下新建util包

util包下面新建两个文件

log.py

"""操作日志记录
"""
import time
from loguru import logger
from pathlib import Path
from util.pathutil import Pathutil
# project_path = Path.cwd().parent
pathutil = Pathutil()
project_path = pathutil.rootPath
log_path = Path(project_path, "log")
t = time.strftime("%Y_%m_%d")


class Loggings:
    __instance = None
    logger.add(f"{log_path}/interface_log_{t}.log", rotation="500MB", encoding="utf-8", enqueue=True,
               retention="10 days")

    def __new__(cls, *args, **kwargs):
        if not cls.__instance:
            cls.__instance = super(Loggings, cls).__new__(cls, *args, **kwargs)

        return cls.__instance

    def info(self, msg):
        return logger.info(msg)

    def debug(self, msg):
        return logger.debug(msg)

    def warning(self, msg):
        return logger.warning(msg)

    def error(self, msg):
        return logger.error(msg)


loggings = Loggings()
if __name__ == '__main__':
    loggings.info("中文test")
    loggings.debug("中文test")
    loggings.warning("中文test")
    loggings.error("中文test")

    logger.info('If you are using Python {}, prefer {feature} of course!', 3.6, feature='f-strings')
    n1 = "cool"
    n2 = [1, 2, 3]
    logger.info(f'If you are using Python {n1}, prefer {n2} of course!')

 

 

pathutil.py

import sys
import os


class Pathutil(object):
    """路径处理工具类"""

    def __init__(self):
        # 判断调试模式
        debug_vars = dict((a, b) for a, b in os.environ.items() if a.find('IPYTHONENABLE') >= 0)

        # 根据不同场景获取根目录
        if len(debug_vars) > 0:
            """当前为debug运行时"""
            self.rootPath = sys.path[2]
        elif getattr(sys, 'frozen', False):
            """当前为exe运行时"""
            self.rootPath = os.getcwd()
        else:
            """正常执行"""
            self.rootPath = sys.path[1]

        # 替换斜杠
        self.rootPath = self.rootPath.replace("\\", "/")

    def getPathFromResources(self, fileName):
        """按照文件名拼接资源文件路径"""
        filePath = "%s/resources/%s" % (self.rootPath, fileName)
        return filePath

 

使用方式：

main.py

from util import log
log = log.Loggings()


if __name__ == '__main__':
    log.info("fafa")
