我正在尝试在测试期间使用 FTP 服务器存根。我不想要控制台输出，但我想将日志记录到文件中。

我希望 FTP 服务器在不同的进程中运行，所以我使用多处理。

我的代码如下将所有日志记录设置为级别WARNING：

from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.handlers import FTPHandler
from pyftpdlib.servers import FTPServer
import pyftpdlib.log as pyftpdliblog
import os
import logging
import multiprocessing as mp

authorizer = DummyAuthorizer()
authorizer.add_user('user', '12345', '.', perm='elradfmwM')
handler = FTPHandler
handler.authorizer = authorizer

pyftpdliblog.LEVEL = logging.WARNING
logging.basicConfig(filename='pyftpd.log', level=logging.INFO)
server = FTPServer(('', 2121), handler)

def main():
    p = mp.Process(target=server.serve_forever)
    p.start()


if __name__ == '__main__':
    main()

如何仅将控制台日志记录设置为 WARNING 级别，或者更好的是完全关闭而不放弃文件日志记录？

所以，在深入挖掘代码之后，我发现了以下提示：

# This is a method of FTPServer and it is called before 
# server.serve_forever
def _log_start(self):
    if not logging.getLogger('pyftpdlib').handlers:
        # If we get to this point it means the user hasn't
        # configured logger. We want to log by default so
        # we configure logging ourselves so that it will
        # print to stderr.
        from pyftpdlib.ioloop import _config_logging
        _config_logging()

所以，我所要做的就是定义我自己的合适的处理程序：

logger = logging.getLogger('pyftpdlib')
logger.setLevel(logging.INFO)
hdlr = logging.FileHandler('pyftpd.log' )
logger.addHandler(hdlr)

现在，有文件日志记录，但控制台日志记录不会启动。

像这样的东西：

import logging

date_format = "%Y/%m/%d %H:%M:%S"
log_file_path = "my_file.txt"

root_logger = logging.getLogger()
root_logger.setLevel(logging.DEBUG)

# own_module_logger = logging.getLogger(__name__)
pyftpdlib_logger = logging.getLogger("pyftpdlib")

# Setup logging to file (Only pyftpdlib)
filehandler = logging.FileHandler(filename = log_file_path)
filehandler.setLevel(logging.DEBUG)
fileformatter = logging.Formatter(fmt = "%(asctime)s - %(levelname)-8s - %(name)s.%(funcName)s - %(message)s",
                                  datefmt = date_format)
filehandler.setFormatter(fileformatter)
pyftpdlib_logger.addHandler(filehandler)
pyftpdlib_logger.propagate = False

# Setup logging to console (All other)
console = logging.StreamHandler()
console.setLevel(logging.INFO)
consoleformatter = logging.Formatter(fmt = "%(asctime)s - %(levelname)-8s - %(name)s.%(funcName)s - %(message)s",
                                     datefmt = date_format)
console.setFormatter(consoleformatter)
root_logger.addHandler(console)

# Do your loggings
a = logging.getLogger()
a.info('root I')
a.debug('root D')

b = logging.getLogger("pyftpdlib")
b.info('P I')
b.debug('P D')

logging.shutdown()

所以 pyftpdlib 的日志记录到文件中。从你的模块到控制台的一切。这里的关键之一是传播！
