问题描述
I have a logger that has a RotatingFileHandler.
I want to redirect all Stdout and Stderr to the logger.
How to do so?
解决方案
Not enough rep to comment, but I wanted to add the version of this that worked for me in case others are in a similar situation.
class LoggerWriter:
def __init__(self, level):
# self.level is really like using log.debug(message)
# at least in my case
self.level = level
def write(self, message):
# if statement reduces the amount of newlines that are
# printed to the logger
if message != '
':
self.level(message)
def flush(self):
# create a flush method so things can be flushed when
# the system wants to. Not sure if simply 'printing'
# sys.stderr is the correct way to do it, but it seemed
# to work properly for me.
self.level(sys.stderr)
and this would look something like:
log = logging.getLogger('foobar')
sys.stdout = LoggerWriter(log.debug)
sys.stderr = LoggerWriter(log.warning)
