5.安装djangorestframework

6.配置

添加rest_framework到INSTALLED_APPS

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'server',
    'rest_framework',

]

server目录下新建一个urls.py作为路由

from django.contrib import admin
from django.conf.urls import url, include
from server import views
urlpatterns = [
    url('test/', views.test)
]

在views.py里新建一个方法

# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.shortcuts import render
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.decorators import api_view
from django.http import JsonResponse, HttpResponseNotAllowed, HttpResponse
# Create your views here.
@api_view(['GET'])
def test(request):
    if request.method == 'GET':
        content = {'msg': 'SUCCESS'}
        return JsonResponse(data=content, safe=False)

修改根目录下面的urls.py

"""myproject URL Configuration

"""
from django.conf.urls import url,include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url('', include('server.urls')),
]
