REST与技术无关，代表的是一种软件架构风格，REST是Representational State Transfer的简称，中文翻译为“表征状态转移”或“表现层状态转化”。
urls
urlpatterns = [url(r'^users', Users.as_view()),
]
view(视图)
from django.views import View
from django.http import JsonResponseclass Users(View):def get(self, request, *args, **kwargs):result = {'code': 0,'data': 'response data'}return JsonResponse(result, status=200)def post(self, request, *args, **kwargs):result = {'code': 0,'data': 'response data'}return JsonResponse(result, status=200)
基于Django REST Framework框架实现
**在settings中注册 'rest_framework',**```
from django.conf.urls import url, include
from web.views.s1_api import TestViewurlpatterns = [url(r'^test/', TestView.as_view()),
]
```
视图
from rest_framework.views import APIView
from rest_framework.response import Responseclass TestView(APIView):def dispatch(self, request, *args, **kwargs):"""请求到来之后，都要执行dispatch方法，dispatch方法根据请求方式不同触发 get/post/put等方法注意：APIView中的dispatch方法有好多好多的功能"""return super().dispatch(request, *args, **kwargs)def get(self, request, *args, **kwargs):return Response('GET请求，响应内容')def post(self, request, *args, **kwargs):return Response('POST请求，响应内容')def put(self, request, *args, **kwargs):return Response('PUT请求，响应内容')
上述就是使用Django REST framework框架搭建API的基本流程，重要的功能是在APIView的dispatch中触发。
在django自定义 RESTful
在页面中写<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>home</title>
</head>
<body><form action="http://127.0.0.1:8989/index/" method="post"><input type="text" name=username><input type="submit">
</form>
<button id="b1">点我发跨域请求</button>
<div id="box1"></div>
<script src="jquery-3.3.1.min.js"></script>
<script>function func(data) {console.log(data);console.log(data.name);//ok}
</script><script src="http://127.0.0.1:8989/index/"></script>
<script>$('#b1').click(function () {$.ajax({url:'http://127.0.0.1:8989/index/',type:'get',success:function (response_ret) {console.log(response_ret);console.log(response_ret.name);}})})
</script>
</body>
</html>
在视图中
```
data = {'name': 'bigc', 'age': 18}
def index(request):# 获取form post请求的数据if request.method == 'POST':print(request.POST.get('username'))return HttpResponse('func({})'.format(json.dumps(data)))
```
在中间件中写入如下
from django.utils.deprecation import MiddlewareMixin
class Cors(MiddlewareMixin):def process_response(self, request, response):# 指定的ip可以发送跨域请求# response['Access-Control-Allow-Origin'] = 'http://localhost:63342'# 所有的跨域访问都响应response['Access-Control-Allow-Origin'] = '*'if request.method == 'OPTIONS':# 给contentType 为application/json的放行response['Access-Control-Allow-Headers'] = 'Content-Type'# 给PUT,DELETE,放行response['Access-Control-Allow-Methods'] = 'PUT, DELETE'return response
