DRF补充数据库异常和Redis异常
(1)在项目适当位置新建exceptions.py,内容如下:
from rest_framework.views import exception_handler as drf_exception_handler
import logging
from django.db import DatabaseError
from redis.exceptions import RedisError
from rest_framework.response import Response
from rest_framework import status
# 获取在配置文件中定义的logger,用来记录日志
logger = logging.getLogger('django')
def exception_handler(exc, context):
"""
自定义异常处理
:param exc: 异常
:param context: 抛出异常的上下文
:return: Response响应对象
"""
# 调用drf框架原生的异常处理方法
response = drf_exception_handler(exc, context)
if response is None:
view = context['view']
if isinstance(exc, DatabaseError) or isinstance(exc, RedisError):
# 数据库异常
logger.error('[%s] %s' % (view, exc))
response = Response({'message': '服务器内部错误'}, status=status.HTTP_507_INSUFFICIENT_STORAGE)
return response
(2)在配置文件中配置如下内容:
REST_FRAMEWORK = {
# 异常处理
'EXCEPTION_HANDLER': 'meiduo_mall.utils.exceptions.exception_handler', # 路径需要修改
}
