如何在django-rest-framework中获取特定索引内的数组数据

from rest_framework import serializers

class MySerializer(serializers.Serializer):
    my_array = serializers.ListField(child=serializers.CharField())

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

class MyView(APIView):
    def get(self, request, index):
        data = [...]  # 获取原始数据
        serializer = MySerializer(data=data)
        serializer.is_valid(raise_exception=True)
        my_array = serializer.validated_data['my_array']
        if index < len(my_array):
            return Response(my_array[index])
        else:
            return Response("Index out of range")
