如何从DRF序列化程序传递查询参数

from django_filters.rest_framework import DjangoFilterBackend
from .filters import CustomFilter

class MyView(APIView):
    filter_backends = [DjangoFilterBackend]

from django_filters import rest_framework as filters

class CustomFilter(filters.FilterSet):
    # 定义过滤器字段
    field_name = filters.CharFilter(field_name='field_name', lookup_expr='exact')

    class Meta:
        model = MyModel
        fields = ['field_name']

class MyView(APIView):
    filter_backends = [DjangoFilterBackend]
    filterset_class = CustomFilter

from rest_framework import serializers

class MySerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = '__all__'

    def get_queryset(self):
        queryset = super().get_queryset()
        query_params = self.context['request'].query_params

        # 根据查询参数进行过滤
        field_name = query_params.get('field_name')
        if field_name:
            queryset = queryset.filter(field_name=field_name)

        return queryset
