使用serialize时多数据传递

class CartList(APIView):

#定义编辑方法

def post(self,request):

username = request.POST.get('username')

# print(username)

 

idlist = cache.get(username)

 

sum = len(idlist)

test_dict = {}

#遍历数组

for key in idlist:

#通过key来计算元素个数

test_dict[key] = test_dict.get(key,0) + 1

 

print(test_dict)

# print(idlist)

for i in idlist:

res = CommoDity.objects.filter(id__in=idlist)

 

print(type(test_dict))

data = serialize('json',res,ensure_ascii=False)

 

return Response([test_dict,data,sum])

 

 

注：Response内用列表形式进行多数据传递  忘谨记
