　　django-rest-framework,是一套基于Django 的 REST 框架，是一个强大灵活的构建 Web API 的工具包。

3.1.2 DjangoRESTframework依赖Django；

官方文档：http://www.django-rest-framework.org/

pip install djangorestframework
pip install markdown
pip install django-filter

3.1.3 settings.py中修改数据库指向为为MySQL；

DATABASES = {    'default': {        'ENGINE': 'django.db.backends.mysql',        'NAME': 'MxShop',        'USER': 'root',        'PASSWORD': 'Tqtl911!@#)^',        'HOST': '127.0.0.1',        'PORT': '3306',        'OPTIONS': {'init_command': 'SET default_storage_engine =INNODB;'},    }}

3.1.4 pip3 install mysqlclient 代替python-mysql；

报错信息：

    'Did you install mysqlclient or MySQL-python?' % e
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named 'MySQLdb'.
Did you install mysqlclient or MySQL-python?

4-1 restful API介绍

4.1.1 RESTful API详解；

https://www.runoob.com/w3cnote/restful-architecture.html

4.1.2 前后端分离的优缺点，为什么要进行前后端分离；

1、PC、APP、PAD等多端以及Android、IOS适应；
2、SPA开发模式流程，SPA，single page即单页面——后端提供API接口；
3、前后端开发职责不清楚，模板语言DTL、Jinja2应该由谁来写？
4、PHP和Java的模本可以写比较复杂的语法；
5、开发效率的问题，前后端岗位互等；
6、前端一直配置着后端，能力受限；
7、后台开发语言和模板高度耦合，导致开发语言依赖严重；

1、前后端学习门槛增加；

2、数据依赖导致文档重要性增加；

3、前端工作量加大；

4、SEO的难度加大-爬虫拿到的数据将减少；如果不考虑SEO，那么前后端分离将成为必然；

5、后端开发模式迁移成本增加；

4.1.3 RESTful API是目前前后端分离的最佳实践-即约定好的标准；

轻量，直接通过http，不需要额外的协议，post、get、put、delete的操作；
面向资源，一幕了然，具有自解释性；比如商品、课程；
数据描述简单，一般通过json或者xml做数据通信；

4-2 Vue的基本概念介绍

4.2.1 概念初识；

前端工程化；
数据双向绑定——mvvm；
组件化开发；

4.2.2 Node.js以及webpack出来之后，带动了js的飞速发展；

vue.js：https://cn.vuejs.org/v2/guide/

4.2.3 Vue开发的几个概念；

webpack-将所有东西变成一个js文件；
vue、vuex、vue-router、axios（发送Ajax请求）；
ES6、babel；基于ES6开发，babel是一个将ES6转换为ES5的转换器；

4-3 Vue源码结构介绍

4.3.1 Vue项目目录结构介绍；

5-1 Django的view实现商品列表页

5.1.1 Chrome浏览器添加JsonView插件；

views_base.py;

#!/usr/bin/python3

5-3 apiview方式实现商品列表页-1

5.3.1 使用drf代替Django REST framework的读法；

pip3 install coreapi djangorestframework markdown django-filter django-guardian

5.3.2 为什么使用Django REST framework来代替Django + serializer呢？

5.3.3 一定要在settings.py中配置rest_framework;

5-4 apiview实现商品列表页-2

5.4.1 报错处理TypeError: str returned non-string (type NoneType)；

https://blog.csdn.net/WangXJ101010/article/details/78458481

goods/views.py;

from django.shortcuts import render# Create your views here.
from .serializers import GoodsSerializer
from rest_framework.views import APIView
from rest_framework.response import Responsefrom .models import Goodsclass GoodsListView(APIView):"""List all goods"""def get(self, request, format=None):goods = Goods.objects.all()[:10]goods_serializer = GoodsSerializer(goods, many=True)return Response(goods_serializer.data)

5-5 drf的modelserial实现商品列表页功能

5.5.1 Bug处理将name改为username；

5.5.2 rest_framework中的状态码；

5-6 GenericView方式实现商品列表页和分页功能介绍
