一、响应器作用:
根据用户请求URL或者用户可接受的类型,筛选出合适的渲染组件
用户的请求URL:
http://127.0.0.1:8000/test/?format=json
http://127.0.0.1:8000/test.json
二、内置渲染器
显示Json格式:
显示json格式:JSONRenderer
访问URL:
- http://127.0.0.1:8000/test/?format=json
- http://127.0.0.1:8000/test.json
- http://127.0.0.1:8000/test/
默认显示格式:BrowsableAPIRenderer(可以修改它的html文件)
访问URL:
- http://127.0.0.1:8000/test/?format=api
- http://127.0.0.1:8000/test.api
- http://127.0.0.1:8000/test/
表格方式:AdminRenderer
访问URL:
- http://127.0.0.1:8000/test/?format=admin
- http://127.0.0.1:8000/test.admin
- http://127.0.0.1:8000/test/
form表单方式:HTMLFormRenderer
访问URL:
- http://127.0.0.1:8000/test/?format=form
- http://127.0.0.1:8000/test.form
- http://127.0.0.1:8000/test/
三、局部使用
from rest_framework.renderers import HTMLFormRenderer,BrowsableAPIRenderer class BookDetailView(APIView): renderer_classes = [HTMLFormRenderer,BrowsableAPIRenderer ] def get(self,request,pk): book_obj=models.Book.objects.filter(pk=pk).first() bs=BookSerializers(book_obj,many=False) return Response(bs.data) def put(self,request,pk): book_obj = models.Book.objects.filter(pk=pk).first() bs=BookSerializers(data=request.data,instance=book_obj) if bs.is_valid(): bs.save() # update return Response(bs.data) else: return Response(bs.errors) def delete(self,request,pk): models.Book.objects.filter(pk=pk).delete() return Response("")
四、全局使用
settings里配置:
REST_FRAMEWORK = { 'DEFAULT_RENDERER_CLASSES':['rest_framework.renderers.JSONRenderer'] }
五、自定义显示模板
from rest_framework.renderers import TemplateHTMLRenderer class BookDetailView(APIView): renderer_classes = [TemplateHTMLRenderer] def get(self,request,pk): book_obj=models.Book.objects.filter(pk=pk).first() bs=BookSerializers(book_obj,many=False) return Response(bs.data,template_name='aa.html')
