在python-daemon 中用logging写入日志问题

import logging
import daemon

Channe = "/python/YueNan/log/"
channl_name = "yuenan"

logging.basicConfig(filename=Channe + channl_name + ".log",level=logging.INFO,format='%(asctime)s:%(levelname)s:%(message)s')

logging.info("开始关服1")

with daemon.DaemonContext():
    logging.info("开始开服服")

 

这样写时， logging.info("开始开服服")这一句始终写不进日志文件中。

这是运行daemon时把日志IO都关闭了。

这样写就ok了。

 

import logging
import daemon

Channe = "/python/YueNan/log/"
channl_name = "yuenan"

logging.basicConfig(filename=Channe + channl_name + ".log",level=logging.INFO,format='%(asctime)s:%(levelname)s:%(message)s')
 

logger = logging.getLogger()

#得到io地址：[<_io.TextIOWrapper name='/python/YueNan/log/yuenan.log' mode='a' encoding='UTF-8'>]
logger_io= [handler.stream for handler in logger.handlers]
logging.info("开始关服1")

with daemon.DaemonContext(files_preserve = logger_io):
    logging.info("开始开服服")
