#1.导入Django自带的原生的序列化模块
from django.core.serializers import serialize

class CourseView(APIView):
    def get(self,request):
        #获取queryset
        origin_data = Course.objects.all()
        #对queryset进行序列化
        serialized_data = serialize("json",origin_data)
        #将序列化后的数据，响应给客户端
        return HttpResponse(serialized_data)
