Django Rest Framework
什么是Restful
REST代表的是一种软件架构风格,REST是Representational State Transfer的简称,中文翻译为“表征状态转移”。
REST从资源的角度类审视整个网络,将分布的网络中某个节点的资源通过URL进行标识,客户端应用通过URL来获取资源的表征,获得这些表征只是这些应用转变状态。
所有的数据,无论是通过网络获取的还是操作(增删改查)的数据,都是资源,将一切数据视为资源是REST区别其他架构风格的最本质属性。
对于REST这种面向资源的架构风格,即:面向资源架构(ROA:Resource Oriented Architecture)。
Restful API设计规范
-API与用户的通信协议,总是使用HTTPs协议
-域名
应该尽量将API部署在专用域名之下,如:https://api.example.com
如果确定API很简单也可以放在主域名下:https://example.org/api/
-版本
应将API的版本号放入URL
https://api.example.com/v1/
方法有很多,可将版本号放在HTTP头信息中,但不如放入URL方便和直观
-路径 网络上的任何东西都是资源,均使用名词表示(可复数)
https://api.example.com/v1/zoos
https://api.example.com/v1/animals
-HTTP动词
对资源的具体操作类型,有HTTP动词表示,常用的HTTP动词有下面五种(括号为sql命令)
GET (SELECT):从服务器取出资源(一项或多项)
POST (CREATE):在服务器新建一个资源
PUT (UPDATE):在服务器更新资源(客户端提供改变后的完整资源)
PATCH (UPDATE):在服务器更新资源(客户端提供改变的属性)
DELETE (DELETE):从服务器删除资源
下面是一些例子。
GET /zoos:列出所有动物园
POST /zoos:新建一个动物园
GET /zoos/ID:获取某个指定动物园的信息
PUT /zoos/ID:更新某个指定动物园的信息(提供该动物园的全部信息)
PATCH /zoos/ID:更新某个指定动物园的信息(提供该动物园的部分信息)
DELETE /zoos/ID:删除某个动物园
GET /zoos/ID/animals:列出某个指定动物园的所有动物
DELETE /zoos/ID/animals/ID:删除某个指定动物园的指定动物
-过滤 如果记录数据很多,服务器不可能将它们返回给用户,API应提供参数过滤返回
https://api.example.com/v1/zoos?limit=10:指定返回记录的数量
https://api.example.com/v1/zoos?offset=10:指定返回记录的开始位置
https://api.example.com/v1/zoos?page=2&per_page=100:指定第几页,以及每页的记录数
https://api.example.com/v1/zoos?sortby=name&order=asc:指定返回结果按照哪个属性排序,以及排序顺序
https://api.example.com/v1/zoos?animal_type_id=1:指定筛选条件
参数的设计允许存在冗余,即允许API路径和URL参数偶尔有重复。比如,GET /zoo/ID/animals 与 GET /animals?zoo_id=ID 的含义是相同的
-状态码 服务器向用户返回的状态码和提示信息,常见的有以下一些(方括号中是该状态码对应的HTTP动词)。
200 OK - [GET]:服务器成功返回用户请求的数据,该操作是幂等的(Idempotent)。
201 CREATED - [POST/PUT/PATCH]:用户新建或修改数据成功。
202 Accepted - [*]:表示一个请求已经进入后台排队(异步任务)
204 NO CONTENT - [DELETE]:用户删除数据成功。
400 INVALID REQUEST - [POST/PUT/PATCH]:用户发出的请求有错误,服务器没有进行新建或修改数据的操作,该操作是幂等的。
401 Unauthorized - [*]:表示用户没有权限(令牌、用户名、密码错误)。
403 Forbidden - [*] 表示用户得到授权(与401错误相对),但是访问是被禁止的。
404 NOT FOUND - [*]:用户发出的请求针对的是不存在的记录,服务器没有进行操作,该操作是幂等的。
406 Not Acceptable - [GET]:用户请求的格式不可得(比如用户请求JSON格式,但是只有XML格式)。
410 Gone -[GET]:用户请求的资源被永久删除,且不会再得到的。
422 Unprocesable entity - [POST/PUT/PATCH] 当创建一个对象时,发生一个验证错误。
500 INTERNAL SERVER ERROR - [*]:服务器发生错误,用户将无法判断发出的请求是否成功。
-错误处理
{
code:123456,
error:"error info"
}
-返回结果 针对不同操作,服务器向用户返回的结果应符合以下规范
GET /collection:返回资源对象的列表(数组)
GET /collection/resource:返回单个资源对象
POST /collection:返回新生成的资源对象
PUT /collection/resource:返回完整的资源对象
PATCH /collection/resource:返回完整的资源对象
DELETE /collection/resource:返回一个空文档
-Hypermedia API
RESTful API最好做到Hypermedia,即返回结果中提供链接,连向其他API方法,使得用户不查文档,也知道下一步应该做什么。
比如,当用户向api.example.com的根目录发出请求,会得到这样一个文档。
{"link": {
"rel": "collection https://www.example.com/zoos",
"href": "https://api.example.com/zoos",
"title": "List of zoos",
"type": "application/vnd.yourformat+json"
}}
基于Django实现
1 路由系统 2 urlpatterns = [ 3 url(r'^users', Users.as_view()), 4 ] 5 CBV视图 6 from django.views import View 7 from django.http import JsonResponse 8 9 class Users(View): 10 def get(self, request, *args, **kwargs): 11 result = { 12 'status': True, 13 'data': 'response data' 14 } 15 return JsonResponse(result, status=200) 16 17 def post(self, request, *args, **kwargs): 18 result = { 19 'status': True, 20 'data': 'response data' 21 } 22 return JsonResponse(result, status=200)

7.url路由控制
自定义路由
1 from django.conf.urls import url, include 2 from web.views import s11_render 3 urlpatterns = [ 4 url(r'^test/$', s11_render.TestView.as_view()), 5 url(r'^test\.(?P<format>[a-z0-9]+)$', s11_render.TestView.as_view()), 6 url(r'^test/(?P<pk>[^/.]+)/$', s11_render.TestView.as_view()), 7 url(r'^test/(?P<pk>[^/.]+)\.(?P<format>[a-z0-9]+)$', s11_render.TestView.as_view()) 8 ] 9 10 from rest_framework.views import APIView 11 from rest_framework.response import Response 12 from .. import models 13 class TestView(APIView): 14 def get(self, request, *args, **kwargs): 15 print(kwargs) 16 print(self.renderer_classes) 17 return Response('...')
半自动路由
1 from django.conf.urls import url, include 2 from web.views import s10_generic 3 4 urlpatterns = [ 5 url(r'^test/$', s10_generic.UserViewSet.as_view({'get': 'list', 'post': 'create'})), 6 url(r'^test/(?P<pk>\d+)/$', s10_generic.UserViewSet.as_view( 7 {'get': 'retrieve', 'put': 'update', 'patch': 'partial_update', 'delete': 'destroy'})), 8 ] 9 10 from rest_framework.viewsets import ModelViewSet 11 from rest_framework import serializers 12 from .. import models 13 14 class UserSerializer(serializers.ModelSerializer): 15 class Meta: 16 model = models.UserInfo 17 fields = "__all__" 18 19 class UserViewSet(ModelViewSet): 20 queryset = models.UserInfo.objects.all() 21 serializer_class = UserSerializer
全自动路由
1 from django.conf.urls import url, include 2 from rest_framework import routers 3 from web.views import s10_generic 4 5 6 router = routers.DefaultRouter() 7 router.register(r'users', s10_generic.UserViewSet) 8 9 urlpatterns = [ 10 url(r'^', include(router.urls)), 11 ] 12 13 from rest_framework.viewsets import ModelViewSet 14 from rest_framework import serializers 15 from .. import models 16 17 18 class UserSerializer(serializers.ModelSerializer): 19 class Meta: 20 model = models.UserInfo 21 fields = "__all__" 22 23 24 class UserViewSet(ModelViewSet): 25 queryset = models.UserInfo.objects.all() 26 serializer_class = UserSerializer
8.分页组件(可在setting全局配置)
根据页码进行分页
1 from rest_framework.pagination import PageNumberPagination 2 class ResultsPagination(PageNumberPagination): 3 page_size = 2 #默认每页显示多少条数据 4 page_size_query_param = "page_size" #获取URL参数设置的每页显示数据条数 5 page_query_param = "page" #获取URL参数中传入的页码 6 max_page_size = 1 #最大支持的每页显示的数据条数 7 8 class BookView(APIView): 9 def get(self,request): 10 book_list=Book.objects.all() 11 # 实例化分页对象,获取数据库中的分页数据 12 paginator = ResultsPagination() 13 page_user_list = paginator.paginate_queryset(book_list,request,self) 14 #把实例化得数据传入序列化组件 15 bs=BookModelSerializers(page_user_list,many=True,context={'request': request}) 16 return Response(bs.data)
根据位置和个数进行分页
1 from rest_framework.pagination import LimiOffsetPagination 2 class ResultsPagination(LimitOffsetPagination): 3 # 默认每页显示的数据条数 4 default_limit = 10 5 # URL中传入的显示数据条数的参数 6 limit_query_param = 'limit' 7 # URL中传入的数据位置的参数 8 offset_query_param = 'offset' 9 # 最大每页显得条数 10 max_limit = None 11 12 class BookView(APIView): 13 def get(self,request): 14 book_list=Book.objects.all() 15 # 实例化分页对象,获取数据库中的分页数据 16 paginator = ResultsPagination() 17 page_user_list = paginator.paginate_queryset(book_list,request,self) 18 #把实例化得数据传入序列化组件 19 bs=BookModelSerializers(page_user_list,many=True,context={'request': request}) 20 return Response(bs.data)
9.版本
基于url的get传参方式
1 REST_FRAMEWORK = { 2 'DEFAULT_VERSION': 'v1', # 默认版本 3 'ALLOWED_VERSIONS': ['v1', 'v2'], # 允许的版本 4 'VERSION_PARAM': 'version' # URL中获取值的key 5 } 6 7 from django.conf.urls import url, include 8 from web.views import TestView 9 urlpatterns = [ 10 url(r'^test/', TestView.as_view(),name='test'), 11 ] 12 13 #!/usr/bin/env python 14 # -*- coding:utf-8 -*- 15 from rest_framework.views import APIView 16 from rest_framework.response import Response 17 from rest_framework.versioning import QueryParameterVersioning 18 class TestView(APIView): 19 versioning_class = QueryParameterVersioning 20 def get(self, request, *args, **kwargs): 21 # 获取版本 22 print(request.version) 23 # 获取版本管理的类 24 print(request.versioning_scheme) 25 # 反向生成URL 26 reverse_url = request.versioning_scheme.reverse('test', request=request) 27 print(reverse_url) 28 return Response('GET请求,响应内容') 29 def post(self, request, *args, **kwargs): 30 return Response('POST请求,响应内容') 31 def put(self, request, *args, **kwargs): 32 return Response('PUT请求,响应内容')
基于url正则方式
1 urls 2 from django.conf.urls import url, include 3 from web.views import TestView 4 5 urlpatterns = [ 6 url(r'^(?P<version>[v1|v2]+)/test/', TestView.as_view(), name='test'), 7 ] 8 9 views 10 11 from rest_framework.views import APIView 12 from rest_framework.response import Response 13 from rest_framework.versioning import URLPathVersioning 14 class TestView(APIView): 15 versioning_class = URLPathVersioning 16 17 def get(self, request, *args, **kwargs): 18 # 获取版本 19 print(request.version) 20 # 获取版本管理的类 21 print(request.versioning_scheme) 22 23 # 反向生成URL 24 reverse_url = request.versioning_scheme.reverse('test', request=request) 25 print(reverse_url) 26 27 return Response('GET请求,响应内容') 28 29 def post(self, request, *args, **kwargs): 30 return Response('POST请求,响应内容') 31 32 def put(self, request, *args, **kwargs): 33 return Response('PUT请求,响应内容') 34 35 setting 36 REST_FRAMEWORK = { 37 'DEFAULT_VERSION': 'v1', # 默认版本 38 'ALLOWED_VERSIONS': ['v1', 'v2'], # 允许的版本 39 'VERSION_PARAM': 'version' # URL中获取值的key 40 }
基于 accept 请求头方式
