利用目录下新建一个serializer.py 例如:/home/serializer.py
from rest_framework import serializersfrom . import modelsclass BannerModelSerializer(serializers.ModelSerializer): class Meta: # 指定轮播图数据模型 model = models.Banner # 指定须要返回的数据，例如只须要 title, link, img_url字段的数据 fields = ['title', 'link', 'img_url']class NavModelsSerializer(serializers.ModelSerializer): class Meta: # 指定导航数据模型 model = models.Nav # 指定须要返回的数据 fields = ['id', 'title', 'link', 'is_site']编写视图层代码：/home/views.py
from rest_framework.generics import ListAPIViewfrom . import modelsfrom .serializer import BannerModelSerializer, NavModelsSerializer# banner轮播图class BannerView(ListAPIView): queryset = models.Banner.objects.filter(is_show=True, is_delete=False).order_by('orders')[0:contains.BANNER_LENGTH] serializer_class = BannerModelSerializer# 顶部导航栏class NavTopView(ListAPIView): queryset = models.Nav.objects.filter(is_show=True, is_delete=False, position=1).order_by('orders')[0:contains.NAV_TOP_LENGTH] serializer_class = NavModelsSerializer路由层代码：/home/urls.py
from django.urls import pathfrom . import viewsurlpatterns = [ # banner接口 path(r'banner/', views.BannerView.as_view()), # 导航栏接口 path(r'nav/top/', views.NavTopView.as_view()),]至此，就写好了两个接口；拜访/banner/和/nav/top/查看返回的数据:
