# 终端日志输出格式
stdout_fmt = '[<cyan>{time:YYYY-MM-DD HH:mm:ss}</cyan>] ' \
             '[<level>{level: <5}</level>] ' \
             '<blue>{module}</blue>:<cyan>{line}</cyan> - ' \
             '<level>{message}</level>'
# 日志文件记录格式
logfile_fmt = '<light-green>{time:YYYY-MM-DD HH:mm:ss,SSS}</light-green> ' \
              '[<level>{level: <5}</level>] ' \
              '<cyan>{process.name}({process.id})</cyan>:' \
              '<cyan>{thread.name: <18}({thread.id: <5})</cyan> | ' \
              '<blue>{module}</blue>.<blue>{function}</blue>:' \
              '<blue>{line}</blue> - <level>{message}</level>'

logger.remove()    #重置自带的输出格式
#自定义级别和输出样式
logger.level(name='TRACE', color='<cyan><bold>', icon='??')
logger.level(name='DEBUG', color='<blue><bold>', icon='🐞 ')
logger.level(name='INFOR', no=20, color='<green><bold>', icon='??')
logger.level(name='CONFIRM', no=20, color='<green><bold>', icon='??')
logger.level(name='QUITE', no=25, color='<green><bold>', icon='🤫 ')
logger.level(name='ALERT', no=30, color='<yellow><bold>', icon='??')
logger.level(name='ERROR', color='<red><bold>', icon='??')
logger.level(name='MISINFORM', no=50, color='<yellow><bold>', icon='??')
logger.level(name='NONES', no=50, color='<yellow><bold>', icon='??')
logger.level(name='FAILS', no=50, color='<yellow><bold>', icon='??')
# confirm CONFIRM

# 命令终端日志级别默认为INFOR
logger.add(sys.stderr, level='INFOR', format=stdout_fmt, enqueue=True)
# 日志文件默认为级别为DEBUG
logger.add(log_path, level='DEBUG', format=logfile_fmt, enqueue=True, encoding='utf-8')


#测试函数
if __name__ == "__main__":
    # logger.log('CONFIRM', 'You must provide either target or targets parameter')
    id=1
    keyword=1
    status_data=1
    logger.log('CONFIRM',f'{id}{keyword}{status_data}')
