python logging模块默认日志_python中的logging记录日志?

import logging
from logging.handlers import TimedRotatingFileHandler
def setup_log():
    # 定义日志输出格式
    fmt_str = '%(asctime)s[level-%(levelname)s][%(name)s]:%(message)s'
    logging.basicConfig(level=logging.INFO)
    # when可设置月、日、时、分、秒等; interval: n个when更新一次; backupCount: 保留m个文件
    files_handle = TimedRotatingFileHandler(path_log, when='S', interval=5, backupCount=7)  # when S M H D midnight
    # 注意时间的格式，区别 - 和 _ , 格式不对影响日志的删除
    files_handle.suffix = "%Y-%m-%d_%H-%M-%S.txt"
    # 设置日志输出级别和格式
    # files_handle.setLevel(logging.DEBUG)
    formatter = logging.Formatter(fmt_str)
    files_handle.setFormatter(formatter)
    # 添加到日志处理对象集合
    logging.getLogger('').addHandler(files_handle)


if __name__ == '__main__':
    setup_log()
    logging.info("程序开始启动")

非主线进程无法保存logging，没找到怎么设置，选择了一种简单粗暴的方式

在进程中将想要保存的日志信息存入队列中，在主线中使用while循环从队列中取出日志信息，使用logging写入文件

示例代码：

q_logs = multiprocessing.Queue()

def log_test():
    for i in range(10):
        q_logs.put(("DEBUG", "DEBUG"))
        q_logs.put(("INFO", "INFO！"))
        q_logs.put(("WARNING", "WARNING!！"))
        q_logs.put(("ERROR", "ERROR!!！"))
        q_logs.put(("CRITICAL", "CRITICAL!!!！"))
        time.sleep(5)
    
def log_write():  
    while True:
        log_leval, log_info = q_logs.get()
        if log_leval == "INFO":
            logging.info(log_info)
        elif log_leval == "WARNING":
            logging.warning(log_info)
        elif log_leval == "ERROR":
            logging.error(log_info)
        elif log_leval == "CRITICAL":
            logging.critical(log_info)
        elif log_leval == "DEBUG":
            logging.debug(log_info)

if __name__ == '__main__':
    # setup_log()
    logging.info("程序开始启动")
    m_test = multiprocessing.Process(target=log_test)
    m_test.start()
    log_write()
