如何在基于函数的api_view中指定DRF oauth required_scopes？

from rest_framework.decorators import api_view, authentication_classes, permission_classes
from rest_framework.permissions import IsAuthenticated
from oauth2_provider.contrib.rest_framework import OAuth2Authentication

@api_view(['GET'])
@authentication_classes([OAuth2Authentication])
@permission_classes([IsAuthenticated])
def my_view(request):
    # 视图的具体实现

from oauth2_provider.contrib.rest_framework import OAuth2Authentication

class CustomOAuth2Authentication(OAuth2Authentication):
    def get_required_scopes(self, request, view):
        return ['scope1', 'scope2']  # 替换为实际需要的scopes列表

from rest_framework.decorators import api_view, authentication_classes, permission_classes
from rest_framework.permissions import IsAuthenticated
from .custom_auth import CustomOAuth2Authentication

@api_view(['GET'])
@authentication_classes([CustomOAuth2Authentication])
@permission_classes([IsAuthenticated])
def my_view(request):
    # 视图的具体实现
