python logging日志防止重复打印

直接上代码

def getLogging(logFilename='/app/logs/logs.txt'):
    logger = logging.getLogger()
    if not logger.handlers:
        logging.basicConfig(
            level=logging.INFO,
            format='%(asctime)s.%(msecs)03d %(levelname)s | [%(threadName)s] %(name)s [%(lineno)d] | %(filename)s %(funcName)s %(message)s',
            datefmt='%Y-%m-%d %H:%M:%S',
            filename=logFilename,
            filemode='a')
        filehandler = logging.FileHandler(logFilename)
        logger.addHandler(filehandler)
    return logger

logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
logger = logging.getLogger(__name__)

多次调用出现重复打印，在获取logger对象的时候判断是否已有handlers

一点小问题，logger自带%(message)s 的消息输出，自己家的话会换行打印一份，我这里需要同行打印不得不加，可自行更改
