在setting.py下:

  1 python
  2 BK_LOG_DIR = os.environ.get(‘BK_LOG_DIR‘, ‘/data/paas/apps/logs/‘)
  3 LOGGING_DIR = os.path.join(BASE_DIR, ‘logs‘, APP_ID)
  4 LOG_CLASS = ‘logging.handlers.RotatingFileHandler‘
  5 LOG_LEVEL = ‘ERROR‘
  6 if RUN_MODE == ‘DEVELOP‘:
  7 LOG_LEVEL = ‘DEBUG‘
  8 elif RUN_MODE == ‘TEST‘:
  9 LOGGING_DIR = os.path.join(BK_LOG_DIR, APP_ID)
 10 LOG_LEVEL = ‘INFO‘
 11 elif RUN_MODE == ‘PRODUCT‘:
 12 LOGGING_DIR = os.path.join(BK_LOG_DIR, APP_ID)
 13 LOG_LEVEL = ‘ERROR‘
 14 
 15 # 自动建立日志目录
 16 if not os.path.exists(LOGGING_DIR):
 17 try:
 18 os.makedirs(LOGGING_DIR)
 19 except:
 20 pass
 21 
 22 LOGGING = {

使用:

test.py下

import logging

logger = logging.getLogger("django")
#几种种模式,记录不同等级的日志
#最后一种用于try,except报错记录日志
logger.debug("test")
logger.info("test")
logger.warning("test")
logger.error("wrong1")
logger.exception("wrong2")
