Quickstart

序列化

创建一个序列化类

简单使用

开发我们的Web API的第一件事是为我们的Web API提供一种将代码片段实例序列化和反序列化为诸如json之类的表示形式的方式。我们可以通过声明与Django forms非常相似的序列化器（serializers）来实现。

models部分:

复制代码
from django.db import models

# Create your models here.


class Book(models.Model):

title=models.CharField(max_length=32)

price=models.IntegerField()

pub_date=models.DateField()

publish=models.ForeignKey("Publish")

authors=models.ManyToManyField("Author")

def str(self):

return self.title


class Publish(models.Model):

name=models.CharField(max_length=32)

email=models.EmailField()

def str(self):

return self.name


class Author(models.Model):

name=models.CharField(max_length=32)

age=models.IntegerField()

def str(self):

return self.name

复制代码

views部分：

复制代码
from rest_framework.views import APIView
from rest_framework.response import Response
from .models import *
from django.shortcuts import HttpResponse
from django.core import serializers

from rest_framework import serializers


class BookSerializers(serializers.Serializer):

title=serializers.CharField(max_length=32)

price=serializers.IntegerField()

pub_date=serializers.DateField()

publish=serializers.CharField(source="publish.name")

#authors=serializers.CharField(source="authors.all")

authors=serializers.SerializerMethodField()

def get_authors(self,obj):

temp=[]

for author in obj.authors.all():

temp.append(author.name)

return temp


class BookViewSet(APIView):


</span><span style="color: #0000ff;">def</span> get(self,request,*args,**<span style="color: #000000;">kwargs):
    book_list</span>=<span style="color: #000000;">Book.objects.all()

    <span style="color: #008000;">#</span><span style="color: #008000;"> return HttpResponse("ok")</span>

    <span style="color: #008000;">#</span><span style="color: #008000;"> 序列化方式2:</span>
    <span style="color: #008000;">#</span><span style="color: #008000;"> data=serializers.serialize("json",book_list)</span>
    <span style="color: #008000;">#</span><span style="color: #008000;"> return HttpResponse(data)</span>

    <span style="color: #008000;">#</span><span style="color: #008000;"> 序列化方式3:</span>
    bs=BookSerializers(book_list,many=<span style="color: #000000;">True)
    </span><span style="color: #0000ff;">return</span> Response(bs.data)</pre>



复制代码

ModelSerializer

class BookSerializers(serializers.ModelSerializer):
      class Meta:
          model=Book
          fields="__all__"
          depth=1

提交post请求

复制代码
  def post(self,request,*args,**kwargs):

    bs</span>=BookSerializers(data=request.data,many=<span style="color: #000000;">False)
    </span><span style="color: #0000ff;">if</span><span style="color: #000000;"> bs.is_valid():
        </span><span style="color: #008000;">#</span><span style="color: #008000;"> print(bs.validated_data)</span>



            bs.save()

return Response(bs.data)

else:

return HttpResponse(bs.errors)

复制代码

重写save中的create方法

复制代码
class BookSerializers(serializers.ModelSerializer):

使用通用的基于类的视图

通过使用mixin类，我们使用更少的代码重写了这些视图，但我们还可以再进一步。REST框架提供了一组已经混合好（mixed-in）的通用视图，我们可以使用它来简化我们的views.py模块。

复制代码
from rest_framework import mixins
from rest_framework import generics

class BookViewSet(generics.ListCreateAPIView):


queryset </span>=<span style="color: #000000;"> Book.objects.all()
serializer_class </span>=<span style="color: #000000;"> BookSerializers



class BookDetailViewSet(generics.RetrieveUpdateDestroyAPIView):

queryset = Book.objects.all()

serializer_class = BookSerializers


class PublishViewSet(generics.ListCreateAPIView):


queryset </span>=<span style="color: #000000;"> Publish.objects.all()
serializer_class </span>=<span style="color: #000000;"> PublshSerializers



class PublishDetailViewSet(generics.RetrieveUpdateDestroyAPIView):

queryset = Publish.objects.all()

serializer_class = PublshSerializers

复制代码

在views.py中：

from app01.service.throttles import *

class BookViewSet(generics.ListCreateAPIView):

throttle_classes = [VisitThrottle,]

queryset = Book.objects.all()

serializer_class = BookSerializers

全局视图throttle

REST_FRAMEWORK={
    "DEFAULT_AUTHENTICATION_CLASSES":["app01.service.auth.Authentication",],
    "DEFAULT_PERMISSION_CLASSES":["app01.service.permissions.SVIPPermission",],
    "DEFAULT_THROTTLE_CLASSES":["app01.service.throttles.VisitThrottle",]
}

内置throttle类

在app01.service.throttles.py修改为：

class VisitThrottle(SimpleRateThrottle):

scope</span>=<span style="color: #800000;">"</span><span style="color: #800000;">visit_rate</span><span style="color: #800000;">"</span>
<span style="color: #0000ff;">def</span><span style="color: #000000;"> get_cache_key(self, request, view):

    </span><span style="color: #0000ff;">return</span> self.get_ident(request)</pre>

settings.py设置：

复制代码
REST_FRAMEWORK={
    "DEFAULT_AUTHENTICATION_CLASSES":["app01.service.auth.Authentication",],
    "DEFAULT_PERMISSION_CLASSES":["app01.service.permissions.SVIPPermission",],
    "DEFAULT_THROTTLE_CLASSES":["app01.service.throttles.VisitThrottle",],
    "DEFAULT_THROTTLE_RATES":{
        "visit_rate":"5/m",
    }
}
