做开发离不开日志,以下是工作中写Django项目常用的logging配置。
BASE_LOG_DIR = os.path.join(BASE_DIR, "log") LOGGING = { ‘version‘: 1, ‘disable_existing_loggers‘: False, ‘formatters‘: { ‘standard‘: { ‘format‘: ‘[%(asctime)s][%(threadName)s:%(thread)d][task_id:%(name)s][%(filename)s:%(lineno)d]‘ ‘[%(levelname)s][%(message)s]‘ }, ‘simple‘: { ‘format‘: ‘[%(levelname)s][%(asctime)s][%(filename)s:%(lineno)d]%(message)s‘ }, ‘collect‘: { ‘format‘: ‘%(message)s‘ } }, ‘filters‘: { ‘require_debug_true‘: { ‘()‘: ‘django.utils.log.RequireDebugTrue‘, }, }, ‘handlers‘: { ‘console‘: { ‘level‘: ‘DEBUG‘, ‘filters‘: [‘require_debug_true‘], # 只有在Django debug为True时才在屏幕打印日志 ‘class‘: ‘logging.StreamHandler‘, ‘formatter‘: ‘simple‘ }, ‘SF‘: { ‘level‘: ‘INFO‘, ‘class‘: ‘logging.handlers.RotatingFileHandler‘, # 保存到文件,根据文件大小自动切 ‘filename‘: os.path.join(BASE_LOG_DIR, "xxx_info.log"), # 日志文件 ‘maxBytes‘: 1024 * 1024 * 50, # 日志大小 50M ‘backupCount‘: 3, # 备份数为3 xx.log --> xx.log.1 --> xx.log.2 --> xx.log.3 ‘formatter‘: ‘standard‘, ‘encoding‘: ‘utf-8‘, }, ‘TF‘: { ‘level‘: ‘INFO‘, ‘class‘: ‘logging.handlers.TimedRotatingFileHandler‘, # 保存到文件,根据时间自动切 ‘filename‘: os.path.join(BASE_LOG_DIR, "xxx_info.log"), # 日志文件 ‘backupCount‘: 3, # 备份数为3 xx.log --> xx.log.2018-08-23_00-00-00 --> xx.log.2018-08-24_00-00-00 --> ... ‘when‘: ‘D‘, # 每天一切, 可选值有S/秒 M/分 H/小时 D/天 W0-W6/周(0=周一) midnight/如果没指定时间就默认在午夜 ‘formatter‘: ‘standard‘, ‘encoding‘: ‘utf-8‘, }, ‘error‘: { ‘level‘: ‘ERROR‘, ‘class‘: ‘logging.handlers.RotatingFileHandler‘, # 保存到文件,自动切 ‘filename‘: os.path.join(BASE_LOG_DIR, "xxx_err.log"), # 日志文件 ‘maxBytes‘: 1024 * 1024 * 5, # 日志大小 50M ‘backupCount‘: 5, ‘formatter‘: ‘standard‘, ‘encoding‘: ‘utf-8‘, }, ‘collect‘: { ‘level‘: ‘INFO‘, ‘class‘: ‘logging.handlers.RotatingFileHandler‘, # 保存到文件,自动切 ‘filename‘: os.path.join(BASE_LOG_DIR, "xxx_collect.log"), ‘maxBytes‘: 1024 * 1024 * 50, # 日志大小 50M ‘backupCount‘: 5, ‘formatter‘: ‘collect‘, ‘encoding‘: "utf-8" } }, ‘loggers‘: { ‘‘: { # 默认的logger应用如下配置 ‘handlers‘: [‘SF‘, ‘console‘, ‘error‘], # 上线之后可以把‘console‘移除 ‘level‘: ‘DEBUG‘, ‘propagate‘: True, }, ‘collect‘: { # 名为 ‘collect‘的logger还单独处理 ‘handlers‘: [‘console‘, ‘collect‘], ‘level‘: ‘INFO‘, } }, }
