在您看来：

假设您在employee_id

中获得request.data

from rest_framework.views import APIView
from rest_framework.response import Response
from myapp.serializers import EmployeeProfileSerializer
from myapp.models import EmployeeProfile


class MyView(APIView):

    def get(self, request, *arga, **kwargs)
        e_profiles = EmployeeProfile.objects.filter(employee__pk=request.GET.get('employee_id'))

        # Then call you serializer

        e_serialized = EmployeeProfileSerializer(e_profiles, many=True)
        return Response(e_serialized.data)
