我正在使用 DJANGO-REST-FRAMEWORK 構建 API。我試圖使用傳遞給請求正文的參數來過濾后端，這是我的設置：views.pyfrom .models import UsStatesGfrom .serializer import UsStatesSerializerfrom rest_framework import viewsetsfrom rest_framework.response import Responsefrom rest_framework.decorators import actionclass StatesViewSet(viewsets.ModelViewSet):    queryset = UsStatesG.objects.all()    serializer_class = UsStatesSerializer    @action(detail=False)    def get_by_id(self, request):        body = request.body.decode('utf-8')        body = json.loads(body)        state_list = UsStatesG.objects.filter(st_abbr__in=body['id'])        serializer = self.get_serializer(state_list, many=True)        return Response(serializer.data)models.pyclass UsStatesG(models.Model):    st_fips = models.CharField(primary_key=True, max_length=2, unique=True)    geom = models.MultiPolygonField(blank=False, null=False)    objectid = models.BigIntegerField(blank=False, null=False)    st_name = models.CharField(max_length=50, blank=False, null=False)    st_abbr = models.CharField(max_length=2, blank=False, null=False, unique=True)    class Meta:        managed = False        db_table = 'US_States_G'urls.pyfrom django.contrib import adminfrom django.urls import include, path, re_pathfrom api import viewsfrom rest_framework.routers import DefaultRouterrouter = DefaultRouter()router.register(r'states', views.StatesViewSet)router.register(r'states/q', views.StatesViewSet.get_by_id, basename='UsStatesG')urlpatterns = [    path('api/location/v1/', include(router.urls)),    serializer.pyfrom rest_framework_gis.serializers import GeoFeatureModelSerializerfrom .models import UsStatesG我想在請求正文中傳遞參數（隱私問題）即正文 {"id": ["TX", "CA"]}因為我對 DRF 還很陌生：1-這是一個好方法嗎？我是否使用了正確的視圖類（視圖集？）？2-過濾模型傳遞從請求正文中獲取的值的最佳（推薦方法）是什么？注意：我正在處理地理空間數據，一個 PostgreSQL-PostGIS Back-end 。我也在使用rest_framework_gis示例代碼將不勝感激，特別推薦 urls.py 和views.py 的代碼
