如何在Django rest框架的ViewSet中设置一个方法,不需要身份验证

我有viewset如下:

from rest_framework import viewsets
from paas.serializers import UserSerializer
import logging


logger=  logging.getLogger(__name__)

class UserViewSet(viewsets.ViewSet):
    def list(self,request):
        pass

    def create(self,request):
        logger.info(request.data)
        current_user = UserSerializer.create()

另外,我在代码中使用基于DRF令牌的身份验证。我怎么能简单地说这个create方法不需要身份验证? 如您所知,在使用令牌实现身份验证后,所有请求都应在标头中有Token,而任何没有请求的请求都会出现403错误。

DRF问题跟踪器上的每this issue,最好的方法似乎是创建自定义权限类。视图对象具有action属性,可用于改变您为响应ViewSet的每个子操作而执行的操作。

class IsCreationOrIsAuthenticated(permissions.BasePermission):

    def has_permission(self, request, view):
        if not request.user.is_authenticated():
            if view.action == 'create':
                return True
            else:
                return False
        else:
            return True
