如何在drf_spectacular (django)中发送带有请求的自定义JSON头？

from rest_framework.views import APIView
from rest_framework.response import Response

class CustomHeaderView(APIView):
    def get(self, request, format=None):
        custom_header = request.META.get('HTTP_X_CUSTOM_HEADER')
        return Response({'custom_header': custom_header})

from rest_framework.test import APITestCase, APIClient

class CustomHeaderTests(APITestCase):
    def setUp(self):
        self.client = APIClient()

    def test_custom_header(self):
        response = self.client.get('/custom-header/', HTTP_X_CUSTOM_HEADER='test_value')
        self.assertEqual(response.status_code, 200)
        self.assertEqual(response.data['custom_header'], 'test_value')

from drf_spectacular.utils import extend_schema, extend_schema_view
from drf_spectacular.types import OpenApiTypes

@extend_schema(request=None, responses={200: {'type': 'object', 'properties': {'custom_header': {'type': 'string'}}}})
@extend_schema_view(get=CustomHeaderView.get)
class CustomHeaderView(APIView):
    def get(self, request, format=None):
        custom_header = request.META.get('HTTP_X_CUSTOM_HEADER')
        return Response({'custom_header': custom_header})
