python logging的应用

1. logger = logging.getLogger(log_name) 是根据log_name返回一个文件流，不通线程中应该传入不通log_name

如果在一个进程中中出现多次创建同一个log_name的文件流也不会报错，并且会重复打印和记录多次，如下：

logger = logging.getLogger(log_name)

import logging
import os
from logging.handlers import TimedRotatingFileHandler


def get_new_logger(log_dir, log_name, output_level=logging.INFO, file_level=logging.INFO, stream_flag=False):
    if not os.path.exists(log_dir):
        os.makedirs(log_dir)
    log_file_path = '%s/%s' % (log_dir, log_name)
    _logger = logging.getLogger(log_name)
    _logger.setLevel(output_level)
    formatter = logging.Formatter('[LOG_INFO] %(asctime)s - %(levelname)s: - %(message)s', datefmt='%Y-%m-%d %H:%M:%S')
    fh = TimedRotatingFileHandler(filename=log_file_path, when="D", interval=1, backupCount=10)
    fh.setLevel(file_level)
    fh.setFormatter(formatter)
    if stream_flag:
        ch = logging.StreamHandler()
        ch.setLevel(output_level)
        ch.setFormatter(formatter)
        _logger.addHandler(ch)
    _logger.addHandler(fh)
    return _logger

class Smoke():
    def __init__(self, orin_type, log_dir, s_update, m_update):
        self.orin_type = orin_type
        self.log_dir = log_dir
        self.name = ('log_' + self.orin_type + '_{}.log').format(date)
        self.logger = get_new_logger(self.log_dir, self.name, output_level=logging.INFO, file_level=logging.INFO,stream_flag=True)


def run(self):
    self.logger.info("run info")
    self.logger.error("run error")
