响应模块

响应模块

1. 作用

根据用户请求URL或用户可接受的类型,筛选出合适的 渲染组件。
用户请求URL:
http://127.0.0.1:8000/test/?format=json
http://127.0.0.1:8000/test.json

2. 内置渲染器

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/

3. 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("")

4. 全局使用

settings.py中配置

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': ['rest_framework.renderers.JSONRenderer']
}

5. 自定义显示模块

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')   
<!DOCTYPE html>
<html lang="en">
<head>
    
    </head> 
    <title>
        Title
    </title>
    
</head>

<body>
	{{ title }}
	{{ publishDate }}
</body>
</html>
