在Django rest框架中过滤给定距离内的用户

from django.contrib.gis.geos import Point
from django.contrib.gis.db.models.functions import Distance
from rest_framework.views import APIView
from rest_framework.response import Response
from .models import User
from .serializers import UserSerializer

class FilterUsersWithinDistance(APIView):
    def get(self, request):
        # 获取客户端传递的距离参数
        distance = request.query_params.get('distance')

        # 获取客户端传递的位置参数
        latitude = request.query_params.get('latitude')
        longitude = request.query_params.get('longitude')

        # 将位置参数转换为经纬度坐标
        location = Point(float(longitude), float(latitude), srid=4326)

        # 使用Django的查询API进行距离过滤
        users = User.objects.annotate(distance=Distance('location', location)).filter(distance__lte=distance)

        # 序列化过滤后的用户数据
        serializer = UserSerializer(users, many=True)

        return Response(serializer.data)
