django restframework 后端接口权限

REST_FRAMEWORK = {
    'EXCEPTION_HANDLER': 'djangoProject.utils.exception.custom_exception_handler',
    # 在不需要权限就能访问的视图 设置permissions_classes=[] 设为空就可以
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',//全局设置
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.BasicAuthentication',
    ),
}

　以上为django的settings文件，以下为指定的view

class BannerListAPIView(ListAPIView):
    # authentication_classes = [OpenedAuthentication]
    permission_classes = []//局部设置会优先于全局设置
    queryset = Banner.objects.filter(is_show=True, is_deleted=False).order_by("-orders", "-id")[
               :constants.BANNER_LENGTH_LIMIT]
    serializer_class = BannerModelSerializer
