使用Django REST以JSON格式从外部URL获取数据

from rest_framework import serializers
from rest_framework import viewsets
from django.shortcuts import render
import requests

class MyDataSerializer(serializers.Serializer):
    field1 = serializers.CharField()
    field2 = serializers.IntegerField()
    # 可以根据实际需要添加更多的字段

class MyDataViewSet(viewsets.ViewSet):
    def list(self, request):
        # 发起外部URL的请求
        response = requests.get('https://example.com/api/data')
        
        # 根据返回的状态码判断请求是否成功
        if response.status_code == 200:
            data = response.json()  # 将响应转换为JSON格式的数据
            serializer = MyDataSerializer(data=data)
            
            # 对获取的数据进行序列化
            if serializer.is_valid():
                return Response(serializer.data)
        return Response(status=status.HTTP_400_BAD_REQUEST)

from django.urls import include, path
from rest_framework.routers import DefaultRouter

router = DefaultRouter()
router.register(r'data', MyDataViewSet, basename='mydata')

urlpatterns = [
    path('', include(router.urls)),
]
