python里的logging怎么写多个文件

Answer 1

an example:

# coding: utf-8
# filename: cfg/logger.yml

version: 1
formatters:
  simple:
    format: '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
  consolefmt:
    format: '%(name)s - %(levelname)s - %(message)s'
handlers:
  console:
    class : logging.StreamHandler
    formatter: consolefmt
    level   : WARNING
    stream  : ext://sys.stdout
  ownerloggerfile:
    class : logging.handlers.RotatingFileHandler
    formatter: simple
    level   : INFO
    filename: log/billingcodeowner.log
    maxBytes: 1048576
    backupCount: 3
  phnloggerfile:
    class : logging.handlers.RotatingFileHandler
    formatter: simple
    level   : INFO
    filename: log/phnparser.log
    maxBytes: 1048576
    backupCount: 3
loggers:
  billingcodeowner:
    level: DEBUG
    handlers: [ownerloggerfile]
    propagate: no
  phoneparser:
    level: DEBUG
    handlers: [console, phnloggerfile]
    propagate: no
root:
  level: DEBUG
  handlers: [console,phnloggerfile]

usage in python application:

import logging
import logging.config
import codecs
import yaml

logging.config.dictConfig(codecs.open("cfg/logger.yml", 'r', 'utf-8').read())
logger = logging.getLogger("billingcodeowner")
