drf-spectacular：使用@extend_schema 指定空负载

问题描述

考虑到我有一个简单的观点，

# serializers.py
class EmptyPayloadResponseSerializer(serializers.Serializer):
    detail = serializers.CharField()


# views.py
from rest_framework.views import APIView
from rest_framework.response import Response
from drf_spectacular.utils import extend_schema
from .serializers import EmptyPayloadResponseSerializer


class EmptyPayloadAPI(APIView):
    @extend_schema(responses=EmptyPayloadResponseSerializer)
    def post(self,request,*args,**kwargs):
        # some actions
        return Response(data={"detail": "Success"})

当我渲染架构时，我收到以下错误响应，

错误 #0：EmptyPayloadAPI：无法猜测序列化程序。这是 APIViews 的优雅回退处理。如果视图在您的控制之下，请考虑使用 GenericAPIView 作为视图基类。暂时忽略视图。

那么，我如何告诉 @extend_schema 装饰器我不打算将任何内容作为有效负载传递？

解决方法

request=None 装饰器中的设置 @extend_schema(...) 可以解决问题！！！

class EmptyPayloadAPI(APIView):
    @extend_schema(request=None,responses=EmptyPayloadResponseSerializer)
    def post(self,request,*args,**kwargs):
        # some actions
        return Response(data={"detail": "Success"})
