class GoodsListView(View):
def get(self, request):
1、方法一：(for in 循环遍历model)
# 定义一个空列表
json_list = []
goods = Goods.objects.all()[:10]
for good in goods:
json_dict = {}
json_dict["name"] = good.name
json_dict["category"] = good.category.name
json_dict["market_price"] = good.market_price
json_dict["add_time"] = good.add_time
json_list.append(json_dict)
from django.http import HttpResponse
import json
# 序列化成json字符串，返给前台
return HttpResponse(json.dumps(json_list), content_type="application/json")
2、方法二：(django自带的serializers序列化model)（推荐使用此方法）
import json
from django.core import serializers
json_data = serializers.serialize('json', goods)
json_data = json.loads(json_data)
from django.http import HttpResponse, JsonResponse
return JsonResponse(json_data, safe=False)
3、方法三：(model_to_dict方法)
from django.forms.models import model_to_dict
for good in goods:
json_dict = model_to_dict(good)
json_list.append(json_dict)
如果遇到无法进行json格式化的格式，例如uuid,需要进行str（）函数转换一下
