我正在尝试django-rest-swagger==2.1.1与使用djangorestframework==3.5.3.

该项目有一些基于类的视图和一些基于函数的视图。集成 swagger 后，它显示“基于类的视图”（显然有序列化器）的 POST 请求的输入框，但不显示“基于函数的视图”。这个问题被问了好几次，我尝试了以下解决方案：

解决 方案1 ​​解决方案2

其他人也很少，但对我的情况不起作用。对于“基于函数的视图”是否有任何可能的方法，或者我必须将它们转换为基于类的视图？

YAML 文档字符串解析器在 REST Swagger>=2.0 中已弃用
我所做的是重写 SchemaGenerator 类以按照我自己的约定解析视图的文档字符串。

from rest_framework import exceptions
from rest_framework.permissions import AllowAny
from rest_framework.renderers import CoreJSONRenderer
from rest_framework.response import Response
from rest_framework.schemas import SchemaGenerator
from rest_framework.views import APIView

from rest_framework_swagger import renderers

import yaml
import coreapi
import urlparse

class SchemaGenerator(SchemaGenerator):
    def get_link(self, path, method, view):
        """Custom the coreapi using the func.__doc__ .

        if __doc__ of the function exist, use the __doc__ building the coreapi. else use the default serializer.

        __doc__ in yaml format, eg:

        description: the desc of this api.
        parameters:
            - name: mobile
              desc: the mobile number
              type: string
              required: true
              location: form
            - name: promotion

        if yaml_doc and type(yaml_doc) != str:

        else:
            encoding = None

        if self.url and path.startswith('/'):
            path = path[1:]

        return coreapi.Link(
            url=urlparse.urljoin(self.url, path),

        )

                )

            return Response(schema)

    return SwaggerSchemaView.as_view()

在项目结构中的任何位置创建此模块。get_swagger_view从此模块导入project/urls.py. 然后，从模块 中删除该get_swagger_view方法。django_rest_swagger

您可以使用装饰器：

from rest_framework.decorators import api_view

然后在您的功能上方使用：

@api_view(['POST'])
