老师，我这边一直没有打印日志，请问怎么回事 我在performance.py文件内容为： import time import logging logger = logging.getLogger(__name__) print(logger) def performance_logger_middleware(get_response): def middleware(request): start_time = time.time() response = get_response(request) duration = time.time() - start_time response["X-Page-Duration-ms"] = int(duration * 1000) logger.info("%s %s %s", duration, request.path, request.GET.dict()) return response return middleware 在base.py中添加日志的代码为： LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'simple': { 'format': '%(asctime)s %(name)-12s %(lineno)d %(levelname)-8s %(message)s' }, }, 'handlers': { 'console': { 'class': 'logging.StreamHandler', 'formatter': 'simple', }, 'mail_admins': { 'level': 'ERROR', 'class': 'django.utils.log.AdminEmailHandler', }, 'file': { #'level': 'INFO', 'class': 'logging.FileHandler', 'formatter': 'simple', 'filename': os.path.join(os.path.dirname(BASE_DIR),'recruitment.admin.log'), }, 'performance':{ 'class': 'logging.FileHandler', 'formatter': 'simple', 'filename': os.path.join(os.path.dirname(BASE_DIR), 'recuritment.performance.log') }, }, 'root': { 'handles': ['console','file'], 'level': 'INFO', }, 'loggers': { "django_python3_ldap": { "handlers": ["console", "file"], "level": "DEBUG", }, "interview.performance": { "handles": ["console","performance"], "level": "INFO", "propagate": False, }, }, }
