django-rest-swagger的优化使用

requirements.txt

django==1.10.5

djangorestframework==3.5.3

django-rest-swagger==2.1.1

参考英文文档：

http://django-rest-swagger.readthedocs.io/en/latest/

使用swagger工具结合Django-rest-framework进行restful API的管理以及可视化显示的时候，由于swagger2.1以后不再使用yaml文档描述api，改而使用json描述，虽然swagger有着自动适配url扫描生成文档的能力，可是自动生成的文档并不详细，然而完全通过json文件描述所有的api，工作量比较大，且有的api也不需要详细描述，因而需要自定义api的json描述和自动扫描生成相结合。

实现如下:

swagger_views.py

# -*- coding: utf-8 -*-

import json
from collections import OrderedDict

from openapi_codec import OpenAPICodec
from openapi_codec.encode import generate_swagger_object
from coreapi.compat import force_bytes

from django.conf import settings

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.schemas import SchemaGenerator

from rest_framework_swagger.renderers import (
    SwaggerUIRenderer,
    OpenAPIRenderer
)


class SwaggerSchemaView(APIView):
    renderer_classes = [
        OpenAPIRenderer,
        SwaggerUIRenderer
    ]

def load_swagger_json(self, doc):
"""
 加载自定义swagger.json文档
 """
        data = generate_swagger_object(doc)
with open(settings.API_DOC_PATH) as s:
            doc_json = json.load(s, object_pairs_hook=OrderedDict)

        data['paths'].update(doc_json.pop('paths'))
        data.update(doc_json)
return OpenAPICodec().decode(force_bytes(json.dumps(data)))

def get(self, request):
        generator = SchemaGenerator(title='后端API文档',
                                    urlconf='chess_user.urls')
        schema = generator.get_schema(request=request)
        document = self.load_swagger_json(schema)

return Response(document)

urls.py

from django.conf.urls import url, include
from django.conf.urls.static import static
from .swagger_views import SwaggerSchemaView


urlpatterns = [
    url(r'^api-doc/$', SwaggerSchemaView.as_view(), name='docs'),

settings.py

SWAGGER_SETTINGS = {
'JSON_EDITOR': True,
'LOGIN_URL': 'login',
'LOGOUT_URL': 'logout',
}

API_DOC_PATH = os.path.join(BASE_DIR, "api-doc/swagger.json")

api-doc/swagger.json

{
    "paths": {
 "v1/user/profile/": {
 "get": {
 "tags": [
"v1"
 ],
 "description": "用户profile\n",
 "responses": {
 "200": {
 "description": "OK",
 "schema": {
 "title": "User",
 "type": "object",
 "properties": {
 "username": {
 "type": "string"
},
 "email": {
 "type": "string"
},
 "phone_number": {
 "type": "string"
}
}
}
}
}
}
}

}
}
