1.获取已发布的广告和店铺列表
1.在apps/ad/views.py中编写 获取已发布的广告或店铺列表类GetPubGoods：
class GetPubGoods(APIView):
"""获取已发布的广告或店铺列表"""
renderer_classes = [JSONRenderer] # 渲染器
def get(self,request):
page=request.GET.get('page')

else:
return HttpResponse('tab1参数异常')
else:
return HttpResponse('参数不足')2.在apps/ad/urls.py中配置路由：
from django.urls import path
from .views import GetCategory,CreateAdOrShop,UpLoadImg,GetGoods,GetImgs,GetPubGoods
urlpatterns = [
path('getcategory/',GetCategory.as_view()),
path('createadorshop/',CreateAdOrShop.as_view()),
path('uploadimg/',UpLoadImg.as_view()),
path('getgoods/',GetGoods.as_view()),
path('getimgs/',GetImgs.as_view()),
path('getpubgoods/',GetPubGoods.as_view()),
]2.获取已发布的广告和店铺详情
1.在apps/ad/views.py中编写 获取广告或店铺详情类 GetGoodDesc：
class GetGoodDesc(APIView):
"""获取广告或店铺详情"""
renderer_classes = [JSONRenderer] # 渲染器
def get(self,request):
good_id=request.GET.get('goodid')
if good_id:
good_id=int(good_id)
good=Good.objects.filter(id=good_id).first()
re_good=GoodModelSerializer(good)
img_obj_list=Images.objects.filter(good=good)
img_list=[]
for item in img_obj_list:
img_list.append(HOST+str(item.image))
return Response(data=({'good':re_good.data,'image_list':img_list}))
return HttpResponse('未收到id')2.在apps/ad/urls.py中编写路由：
from django.urls import path
from .views import GetCategory,CreateAdOrShop,UpLoadImg,GetGoods,GetImgs,GetPubGoods,GetGoodDesc
urlpatterns = [
path('getcategory/',GetCategory.as_view()),
path('createadorshop/',CreateAdOrShop.as_view()),
path('uploadimg/',UpLoadImg.as_view()),
path('getgoods/',GetGoods.as_view()),
path('getimgs/',GetImgs.as_view()),
path('getpubgoods/',GetPubGoods.as_view()),
path('getgooddesc/',GetGoodDesc.as_view()),
