python中添加日志记录到文件

1、实现python日志功能

2、只输出到文件，不输出到控制台

import logging
from common import path_util

logging_level=logging.INFO
fileHandler = logging.FileHandler(path_util.get_abs_path("log","all.log"))
fileHandler.setLevel(logging_level)
formatter = logging.Formatter('%(asctime)s - %(levelname)s %(message)s')
fileHandler.setFormatter(formatter)
logger=logging.getLogger('')
logger.addHandler(fileHandler)

def __get_logger():
    return logger

def info(module_name,message):
    logger.info(get_msg(module_name,message))

def error(module_name,message):
    logger.error(get_msg(module_name,message))

def debug(module_name,message):
    logger.debug(get_msg(module_name,message))

def warn(module_name,message):
    logger.warn(get_msg(module_name,message))

def get_msg(module_name,message):
    return "[MODULE]:{module} :{msg}" .format(module=module_name,msg=message).decode("utf-8")
