Django REST framework

第1章?簡介

Django rest framework?是一套基于django框架編寫restful風格API的組件

第2章?簡單了解下都有哪些特點

2.1serializers（序列化）

就是將復雜的數據結構json化，支持ORM和非ORM數據源的序列化

2.2authentication（身份認證）

快速實現支持auth2和auth3的方式的權限驗證

2.3request and response（請求與響應）

擴展了常規的HttpResquest和TemplateResponse

2.4viewset and routers（視圖和路由）

第3章?開始一個簡單的項目

3.1創建好Django項目后，修改settings文件

INSTALLED_APPS= [
????…….
????'rest_framework',
????'app',
]

DATABASES = {
????'default': {
????????'ENGINE':?'django.db.backends.mysql',
????????'NAME':?'restful',
????????'USER':?'root',
????????'PASSWORD':?'123465',
????????'HOST':?'local.dev',
????????'PORT':?'3306',
????}
}

?

3.2配置urls文件

from?django.conf .urls?import?url,?include


urlpatterns = [
????path('admin/',?admin.site.urls),
????path(r'^test/',?include('app.urls')),
]

3.3編寫model層：

from?django.dbimport?models

# Create your models here.
class?Restful(models.Model):
????name= models.CharField(max_length=30)
????passwd = models.CharField(max_length=10)

????def__str__(self):
????????returnself.name

3.4初始化數據庫

python manage.py makemigrations

python manage.py migrate

3.5編寫序列化模塊：

from?rest_frameworkimport?serializers
from?.models?import?Restful

class?RestfulSerializer(serializers.ModelSerializer):
????classMeta:
????????model = Restful
????????fields = ("id",?"name",?"passwd")

3.6編寫視圖views.py

from?django.shortcutsimport?render

# Create your views here.
from?rest_framework?import?status,?generics
from?rest_framework.response?import?Response
from?rest_framework.views?import?APIView
from?.models?import?Restful
from?.serializer?import?RestfulSerializer


class?RestfulView(APIView):
????defget(self,?request,?format=None):
????????data = Restful.objects.all()
????????serializer = RestfulSerializer(data,?many=True)
????????returnResponse(serializer.data)

????defpost(self,?request,?format=None):
????????serializer = RestfulSerializer(data=request.data)
????????ifserializer.is_valid():
????????????serializer.save()
????????????returnResponse(serializer.data,?status=status.HTTP_201_CREATED)
????????else:
????????????returnResponse(serializer.data,?status=status.HTTP_400_BAD_REQUEST)

3.7編寫app路由urls.py：

from?django.conf.urlsimport?url
from?.?import?views

urlpatterns = [
????url(r'^api/$',?views.RestfulView.as_view(),?name='restful'),
]

3.8進行測試：

插入數據：

???~ curl -X POST http://localhost:8000/test/api/ -d "name=jiangby&passwd=123456"

{"id":1,"name":"jiangby","passwd":"123456"}%????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

???~ curl -X POST http://localhost:8000/test/api/ -d "name=test&passwd=123456"

{"id":2,"name":"test","passwd":"123456"}%

查看數據：
