from .models import Publish
from rest_framework.views import APIView
class PublishView(APIView):
def get(self,request):
#序列化方式4rest_framework
from rest_framework.response import Response
publish_list = Publish.objects.all()
ps = PublishSerializers(publish_list, many=True)
return Response(ps.data)
def post(self,request):
return HttpResponse(‘POST‘)
二、序列化
API返回结果的形式，json是非常流行的。但是我们在序列化结果时，有多种方式，每种方式实现的方式不同。
1、原生json方式
import json
publish_list = list(Publish.objects.all().values())
return HttpResponse(json.dumps(publish_list))
使用json方式对结果进行强转，先把结果强转成列表的方式，然后通过json的dumps方式对结果进行格式化。
注意：
这种方式实现最简单，也可以自定制需要返回的字段。
2、model_to_dict方法
#序列化方式2
# from django.forms.models import model_to_dict
# publish_list = Publish.objects.all()
# data = []
# for obj in publish_list:
# data.append(model_to_dict(obj))
# return HttpResponse(data)
通过models自带的model_to_dict方法直接把obj对象转换成字典的形式，然后返回。缺点：需要把每个对象再次进行处理。
3、django自带的serializers方法
#序列化方式3
# from django.core import serializers
# publish_list = Publish.objects.all()
# data = serializers.serialize("json", publish_list)
# return HttpResponse(data)
4、rest-framework自带serializers方法
from rest_framework import serializers
class PublishSerializers(serializers.Serializer):
name=serializers.CharField(max_length=32)
email=serializers.CharField()
from rest_framework.views import APIView
视图函数继承APIView方法
#序列化方式4rest_framework
from rest_framework.response import Response
publish_list = Publish.objects.all()
ps = PublishSerializers(publish_list, many=True)
return Response(ps.data)
