import logging

# 设置输出文件、文件格式和日志级别

logging.basicConfig(filename='example.log', level=logging.INFO,

                    format='%(asctime)s %(message)s', datefmt='%m/%d/%Y %I:%M:%S %p')

# 开始打印日志信息

logging.debug('This message should go to the log file')

logging.info('So should this')

logging.warning('And this, too')

logging.warning("user [kobe] attempted wrong password more than 3 times")

logging.critical("Server is down...")

# 、创建logger 谁去发日志

logger = logging.getLogger('TEST-LOG')  # 先获取logger对象

logger.setLevel(logging.DEBUG)  # 设置全局日志级别

# 、创建Handler 发给屏幕

ch = logging.StreamHandler()  # 在屏幕上打印

ch.setLevel(logging.DEBUG)  # 设置在屏幕上打印日志的全局级别

# 、创建Handler 文件

fh = logging.FileHandler("access.log")

fh.setLevel(logging.WARNING)  # 日志局部级别

fh_err = logging.FileHandler("error.log")

fh_err.setLevel(logging.ERROR)

# 、创建formatter输出格式

formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

formatter_for_file = logging.Formatter('%(asctime)s - %(filename)s - %(levelname)s - %(message)s')

# 、分别设置格式

ch.setFormatter(formatter)

fh.setFormatter(formatter_for_file)

fh_err.setFormatter(formatter)

# 、向logger注册

logger.addHandler(ch)

logger.addHandler(fh)

logger.addHandler(fh_err)

# 、打印

logger.debug('debug message')

logger.info('info message')

logger.warn('warn message')

logger.error('error message')

logger.critical('critical message')
