DRF框架的安装与使用

DRF框架的安装与配置

"""
1）安装
>: pip install djangorestframework

2）在settings中注册（为什么要注册，后期会讲）
INSTALLED_APPS = [
    # ...
    'rest_framework',
]

3）在settings中自定义drf配置
    REST_FRAMEWORK = {}
注：drf配置查找顺序，自定义settings的REST_FRAMEWORK配置字典 => drf默认settings的DEFAULTS

4）drf的封装特点：特点功能在特点模块下
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.request import Request

基于restful接口规范的接口设计

urlpatterns = [
    # 资源books接口的设计
    url(r'^books/$', views.BookAPIView.as_view()),  # 群查、单增
    url(r'^books/(?P\d+)/$', views.BookAPIView.as_view()),  # 单查、单删、单(整体|局部)改
]
