2 导出项目依赖

# 在虚拟环境中，进到项目根路径，执行
pip freeze > requirements.txt

3 返回格式

1 在common_response.py中：
	from rest_framework.response import Response
	
	
	# APIResponse()
	# APIResponse(result=[{}, {}])
	# APIResponse(token=lin, username=liw)
	# APIResponse(token=fsadfas, username=lin, status=201, headers={'xx': 'xx'})
	class APIResponse(Response):
	    def __init__(self, code=100, msg='成功', status=None,
	                 template_name=None, headers=None,
	                 exception=False, content_type=None, **kwargs):
	        data = {'code': code, 'msg': msg}
	        if kwargs:
	            data.update(kwargs)
	        super().__init__(data=data, status=status, headers=headers, template_name=template_name,
	                         exception=exception, content_type=content_type)
	        # Response(data=data, status=status, headers=headers)

2 在common_mixin.py中：
	from rest_framework.mixins import ListModelMixin
	
	from utils.common_response import APIResponse
	
	
	class CommonListModeMixin(ListModelMixin):
		# 重写list方法
	    def list(self, request, *args, **kwargs):
	        res = super(CommonListModeMixin, self).list(request, *args, **kwargs)
	        return APIResponse(result=res.data)
        
3.在views.py中：
	from rest_framework.mixins import ListModelMixin  # 继承这个路由类缺一个视图类
	from rest_framework.generics import GenericAPIView  # 上述需要配上这个视图
	
	from rest_framework.generics import ListAPIView  # 视图
	
	from rest_framework.viewsets import ViewSetMixin, GenericViewSet  # 自动生成路由
	
	from .models import Banner
	from .serializer import BannerSerializer
	
	from django.conf import settings
	
	from utils.common_mixin import CommonListModeMixin
	
	
	# class BannerView(ViewSetMixin, ListAPIView):
	# class BannerView(ViewSetMixin, GenericAPIView, ListModelMixin):
	
	# 注意：ViewSetMixin, GenericAPIView可以简写成
	# class BannerView(GenericViewSet, ListModelMixin):  # 自动生成路由
	
	class BannerView(GenericViewSet, CommonListModeMixin):  # 自动生成路由
	    # 查询没有删除的和可以展示的，并且按照orders排序, 然后进行切片显示
	    queryset = Banner.objects.filter(is_delete=False, is_show=True).order_by('orders')[:settings.BANNER_COUNT]
	    serializer_class = BannerSerializer
	
	    # 抽取出去生成common_mixin
	    # def list(self, request, *args, **kwargs):
	    #     res = super().list(request, *args, **kwargs)
	    #     return APIResponse(result=res.data)
