Python(2)封装log方法

作者:互联网

logging模块是Python内置的标准模块,主要用于输出运行日志

logging模块的日志级别

日志等级(level)描述
DEBUG 最详细的日志信息,典型应用场景是 问题诊断
INFO 信息详细程度仅次于DEBUG,通常只记录关键节点信息,用于确认一切都是按照我们预期的那样进行工作
WARNING 当某些不期望的事情发生时记录的信息(如,磁盘可用空间较低),但是此时应用程序还是正常运行的
ERROR 由于一个更严重的问题导致某些功能不能正常运行时记录的信息
CRITICAL 当发生严重错误,导致应用程序不能继续运行时记录的信息
二次封装

本封装实现如下简单的调用方式,将自动在项目下创建log目录并记录日志,err日志会单独进行记录

import ...
log=logger.MyLog()
log.info("this is info")
log.debug("this is debug")
log.error("this is error")
log.warning("this is waring")

完整代码如下

import logging
import os
import time

LEVELS = {
    'debug': logging.DEBUG,
    'info': logging.INFO,
    'warning': logging.WARNING,
    'error': logging.ERROR,
    'critical': logging.CRITICAL
}

logger = logging.getLogger()
level = 'default'


def create_file(filename):
    path = filename[0:filename.rfind('/')]
    if not os.path.isdir(path):
        os.makedirs(path)
    if not os.path.isfile(filename):
        fd = open(filename, mode='w', encoding='utf-8')
        fd.close()
    else:
        pass


def set_handler(levels):
    if levels == 'error':
        logger.addHandler(MyLog.err_handler)
    logger.addHandler(MyLog.handler)


def remove_handler(levels):
    if levels == 'error':
        logger.removeHandler(MyLog.err_handler)
    logger.removeHandler(MyLog.handler)


def get_current_time():
    return time.strftime(MyLog.date, time.localtime(time.time()))


class MyLog:
    path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    log_file = path+'/log/'+time.strftime('%Y_%m_%d')+'_log.log'
    err_file = path+'/log/'+time.strftime('%Y_%m_%d')+'_err.log'
    logger.setLevel(LEVELS.get(level, logging.NOTSET))
    create_file(log_file)
    create_file(err_file)
    date = '%Y-%m-%d %H:%M:%S'

    handler = logging.FileHandler(log_file, encoding='utf-8')
    err_handler = logging.FileHandler(err_file, encoding='utf-8')

    @staticmethod
    def debug(log_meg):
        set_handler('debug')
        logger.debug("[DEBUG " + get_current_time() + "]" + log_meg)
        remove_handler('debug')

    @staticmethod
    def info(log_meg):
        set_handler('info')
        logger.info("[INFO " + get_current_time() + "]" + log_meg)
        remove_handler('info')

    @staticmethod
    def warning(log_meg):
        set_handler('warning')
        logger.warning("[WARNING " + get_current_time() + "]" + log_meg)
        remove_handler('warning')

    @staticmethod
    def error(log_meg):
        set_handler('error')
        logger.error("[ERROR " + get_current_time() + "]" + log_meg)
        remove_handler('error')

    @staticmethod
    def critical(log_meg):
        set_handler('critical')
        logger.error("[CRITICAL " + get_current_time() + "]" + log_meg)
        remove_handler('critical')


if __name__ == "__main__":
    MyLog.debug("This is debug message")
    MyLog.info("This is info message")
    MyLog.warning("This is warning message")
    MyLog.error("This is error")
    MyLog.critical("This is critical message")

the end.
