Django REST framework
restful 协议
1.一切皆是资源
2.book表增删改查
-------- 一切皆是资源操作的只是请求方式
/books/ books
/books/add/ addbook
/book/(\d+)/change/ changebook
/book/(\d+)/delete/ delbook
-------- book表增删改查
/books/ -----get books
/books/add/ -----post addbook
/book/(\d+)/change/ -----put changebook
/book/(\d+)/delete/ -------delete delbook
class Books(View)
def get(self,request):
pass # 查看所有书籍
def post(self,request):
pass # 添加书籍
# 其他请求方法
class Books(View)
def get(self,request):
pass # 查看具体书籍
def put (self,request,id):
pass # 更新某本书籍
def post(self,request,id):
pass # 添加书籍
def delete(self,request,id):
pass # 删除某本书籍
from django.contrib import admin
from django.urls import path,re_path
from app01 import views
urlpatterns = [
re_path(r‘^admin/‘, admin.site.urls),
re_path(‘^/index‘, views.index),
re_path(‘^/publishes‘, views.PublishView.as_view()),
]基于fbv的写法：
from django.shortcuts import render
from django.views import View
# Create your views here.
def index(request):
return render(request,"index.html")
class PublishView(View):
def get(self,request):
pass
def post(self,request):
passDjango REST framework介绍
现在前后端分离的架构设计越来越流行，业界甚至出现了API优先的趋势。
显然API开发已经成为后端程序员的必备技能了，那作为Python程序员特别是把Django作为自己主要的开发框架的程序员，我十分推荐Django REST framework（DRF）这个API框架。
Django REST framework（DRF）框架文档齐全，社区较稳定，而且由于它是基于Django这个十分全面的框架而设计开发的，能够让开发者根据自己的业务需要，使用极少的代码量快速的开发一套符合RESTful风格的API，并且还支持自动生成API文档。

反序列化方法
class PublishView(View):
def get(self, request):
# 序列化方式1
# pulish_list = list(models.Publisher.objects.all().values("name","addr"))
# return HttpResponse(json.dumps(pulish_list))
# 序列化方式2
# pulish_list=models.Publisher.objects.all()
# tem=[]
# for obj in pulish_list:
# # 循环一个对象的时候可以这样取值
# tem.append({
# "name":obj.name,
# "addr":obj.addr,
# })
#
# return HttpResponse(json.dumps(tem))
# 序列化方式3
# from django.forms.models import model_to_dict
# pulish_list = models.Publisher.objects.all()
# tem = []
# for obj in pulish_list:
# # model_to_dict 可以直接把一个queyset 对象变成字典
# # {‘id‘: 1, ‘name‘: ‘mark的自我修养‘, ‘addr‘: ‘富士康‘}, {‘id‘: 2, ‘name‘: ‘汨汨的自我修养‘, ‘addr‘: ‘湖南‘}
# tem.append(model_to_dict(obj))
#
# print(tem)
# return HttpResponse(json.dumps(tem))
# 序列化方式4:
from django.core import serializers
pulish_list = models.Publisher.objects.all()
ret=serializers.serialize("json",pulish_list)
return HttpResponse(ret)
