Question

代码如下：

def analysis():
    logging.basicConfig( filename='exception1.log', filemode='a', level=logging.ERROR, format= '%(asctime)s - %(levelname)s - %(message)s')
    logging.FileHandler('/home/aim/top/exception1.log')

    try:
        some_func()
    except Exception as e:
        logging.error("Exception occurred", exc_info=True)
         cur.execute("UPDATE column SET STATUS='FAILED'")
         mydb.commit()
    else:
        cur.execute("UPDATE column SET STATUS='FINISHED'")
        mydb.commit() 
        cur.close()

def analysis1():
    logging.basicConfig( filename='exception2.log', filemode='a', level=logging.ERROR, format= '%(asctime)s - %(levelname)s - %(message)s')
    logging.FileHandler('/home/aim/top-dev/exception1.log')

    try:
        some_func()
    except Exception as e:
        logging.error("Exception occurred", exc_info=True)
         cur.execute("UPDATE column SET STATUS='FAILED'")
         mydb.commit()
    else:
        cur.execute("UPDATE column SET STATUS='FINISHED'")
        mydb.commit() 
        cur.close()


def process():
    if req_type==1:
       analysis()
    if req_type==2:
       analysis1()

运行并获取异常信息后，将正确执行mysql命令，将在两个不同目录中创建日志文件，但在两个文件中的任何一个中均未写入错误。它们是空白。我在做什么错..

Answer 1

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

def setup_logger(name, log_file, level=logging.ERROR):
"""To setup as many loggers as you want"""
    handler = logging.FileHandler(log_file, 'a')        
    handler.setFormatter(formatter)
    logger = logging.getLogger(name)
    logger.setLevel(level)
    logger.addHandler(handler)
    return logger

在每个函数内部调用此函数时，该函数将使用不同的名称为两个函数创建两个单独的日志记录。

def analysis():
logging.basicConfig( filename='logfile.log', filemode='a', level=logging.ERROR, format= '%(asctime)s - %(levelname)s - %(message)s')
logging.FileHandler('/logfile.log')

    try:
        some_func()
    except Exception as e:
        first_logger = setup_logger('first_logger', '/logfile.log')
        first_logger.error("Exception occurred", exc_info=True)
        cur.execute("UPDATE column SET STATUS='FAILED'")
        mydb.commit()
    else:
        cur.execute("UPDATE column SET STATUS='FINISHED'")
        mydb.commit() 
        cur.close()

def analysis1():
    logging.basicConfig( filename='logfile2.log', filemode='a', level=logging.ERROR, format= '%(asctime)s - %(levelname)s - %(message)s')
    logging.FileHandler('/logfile2.log')

    try:
        some_func()
    except Exception as e:
        seccond_logger = setup_logger('second_logger', '/logfile2.log')
        second_logger.error("Exception occurred", exc_info=True)
        cur.execute("UPDATE column SET STATUS='FAILED'")
        mydb.commit()
    else:
        cur.execute("UPDATE column SET STATUS='FINISHED'")
        mydb.commit() 
        cur.close()


def process():
    if req_type==1:
    analysis()
    if req_type==2:
    analysis1()

由于仅为这两个功能创建了一个日志记录实例，所以它不起作用。

Python日志记录未写入日志
