Python的log

關鍵代碼

調用方：

from Logger import MyLogger
import logging
import sys, os

def getLogger():
    # get the file name
    fileUrl = sys.argv[0]
    filepath, tmpfilename = os.path.split(fileUrl)
    shotname, extension = os.path.splitext(tmpfilename)
    
    # get the logger object
    logger = MyLogger(logname='log.txt', loglevel=1, logger=shotname).getlog()
    return logger

logger =getLogger()
logger.debug("Hoory, show!")

 

Logger.py

#開發一個日志系統， 既要把日志輸出到控制台， 還要寫入日志文件  
import logging

class MyLogger():
    format_dict = {
        1 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s'),
        2 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s'),
        3 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s'),
        4 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s'),
        5 : logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    }

    def __init__(self, logname, loglevel, logger):
        '''
           指定保存日志的文件路徑，日志級別，以及調用文件
           將日志存入到指定的文件中
        '''

        # 創建一個logger
        self.logger = logging.getLogger(logger)
        self.logger.setLevel(logging.DEBUG)

        # 創建一個handler，用於寫入日志文件
        fh = logging.FileHandler(logname)
        fh.setLevel(logging.DEBUG)

        # 再創建一個handler，用於輸出到控制台
        ch = logging.StreamHandler()
        ch.setLevel(logging.DEBUG)

        # 定義handler的輸出格式
        formatter = logging.Formatter('%(asctime)s %(name)s %(thread)d %(levelname)s %(message)s')
        fh.setFormatter(formatter)
        ch.setFormatter(formatter)

        # only first time need to add the handler
        if(self.logger.hasHandlers() == False):
            self.logger.addHandler(fh)
            self.logger.addHandler(ch)

   
    def getlog(self):
        return self.logger

 

Logger相關屬性

可以通過下面的代碼來進行設置（基本上不需要這么設置，因為通過getlogger()獲取的logger對象並沒有集成root的相關配置）：

logging.basicConfig(filename="log2.txt", level=logging.WARNING)
