python拦截日志记录到电子邮件或短信

Question

我想知道是否可以拦截日志记录调用以根据级别发送电子邮件或短信。

请记住，在电子邮件和短信下，还有可能导致循环的logging.error

import logging, smtplib, urllib2

LOGGER = 'log.out'
FORMAT = '%(asctime)s %(levelname)s %(message)s'
LEVEL = logging.INFO

logging.basicConfig(filename=LOGGER, format=FORMAT, maxBytes=2048, level=LEVEL)

def email(_msg):
    try:
        email_mesg = "Subject:{0}\n\n{1}".format(email_subj, _msg)
        s = smtplib.SMTP(email_host)
        s.sendmail(email_from, email_recv, email_mesg)
        s.quit()
    except smtplib.SMTPException as e:
        logging.error(e)

def sms(_msg):
    try:
        sms_mesg = urllib2.quote(_msg)
        url = "https://smsapi/?username={0}&password={1}&message={2}&orig={3}&number={4}".format(sms_user, sms_pass, sms_mesg, sms_orig, sms_numb)
        req = urllib2.Request(url)
        res = urllib2.urlopen(req)
    except urllib2.URLError as e:
        logging.error(e)

if __name__ == "__main__":
    """
    The following line should log and trigger email
    """
    logging.warning("Something you should know about")

    """
    The following line should log and trigger sms
    """
    logging.error("Something you should know about")

您可以使用Filter :

import sys, logging

class SMSEmailFilter(logging.Filter):
    def filter(self, record):
        if not record.args:
            if record.levelno == logging.WARN:
                email(record.msg)
            elif record.levelno >= logging.ERROR:
                sms(record.msg)
        return True

logging.basicConfig(level=logging.DEBUG, format='%(asctime)s %(levelname)s %(message)s', stream=sys.stdout)
logger = logging.getLogger()
logger.addFilter(SMSEmailFilter())


def email(_msg):
    try:
        print "Sending email..."
    except:
        logger.error('from email', {'a': 1})


def sms(_msg):
    try:
        print "Sending sms..."
    except:
        logger.error('from sms', {'a': 1})


logger.warning('This is a warning')
logger.error('This is an error')
