    仅处理请求头content-type为application/json的请求体

    from django.conf.urls import url, include
    from web.views.s5_parser import TestView
    
    urlpatterns = [
        url(r'test/', TestView.as_view(), name='test'),
    ]
    #!/usr/bin/env python
    # -*- coding:utf-8 -*-
    from rest_framework.views import APIView
    from rest_framework.response import Response
    from rest_framework.request import Request
    from rest_framework.parsers import JSONParser
    
    
    class TestView(APIView):
        parser_classes = [JSONParser, ]
    
        def post(self, request, *args, **kwargs):
            print(request.content_type)
    
            # 获取请求的值,并使用对应的JSONParser进行处理
            print(request.data)
    
            # application/x-www-form-urlencoded 或 multipart/form-data时,request.POST中才有值
            print(request.POST)
            print(request.FILES)
    
            return Response('POST请求,响应内容')
    
        def put(self, request, *args, **kwargs):
            return Response('PUT请求,响应内容')

    仅处理请求头content-type为application/x-www-form-urlencoded 的请求体

    from django.conf.urls import url, include
    from web.views import TestView
    
    urlpatterns = [
        url(r'test/', TestView.as_view(), name='test'),
    ]
    #!/usr/bin/env python
    # -*- coding:utf-8 -*-
    from rest_framework.views import APIView
    from rest_framework.response import Response
    from rest_framework.request import Request
    from rest_framework.parsers import FormParser
    
    
    class TestView(APIView):
        parser_classes = [FormParser, ]
    
        def post(self, request, *args, **kwargs):
            print(request.content_type)
    
            # 获取请求的值,并使用对应的JSONParser进行处理
            print(request.data)
    
            # application/x-www-form-urlencoded 或 multipart/form-data时,request.POST中才有值
            print(request.POST)
            print(request.FILES)
    
            return Response('POST请求,响应内容')
    
        def put(self, request, *args, **kwargs):
            return Response('PUT请求,响应内容')
    

    仅处理请求头content-type为multipart/form-data的请求体

    from django.conf.urls import url, include
    from web.views import TestView
    
    urlpatterns = [
        url(r'test/', TestView.as_view(), name='test'),
    ]
    #!/usr/bin/env python
    # -*- coding:utf-8 -*-
    from rest_framework.views import APIView
    from rest_framework.response import Response
    from rest_framework.request import Request
    from rest_framework.parsers import MultiPartParser
    
    
    class TestView(APIView):
        parser_classes = [MultiPartParser, ]
    
        def post(self, request, *args, **kwargs):
            print(request.content_type)
    
            # 获取请求的值,并使用对应的JSONParser进行处理
            print(request.data)
            # application/x-www-form-urlencoded 或 multipart/form-data时,request.POST中才有值
            print(request.POST)
            print(request.FILES)
            return Response('POST请求,响应内容')
    
        def put(self, request, *args, **kwargs):
            return Response('PUT请求,响应内容')
    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    <form action="http://127.0.0.1:8000/test/" method="post" enctype="multipart/form-data">
        <input type="text" name="user" />
        <input type="file" name="img">
    
        <input type="submit" value="提交">
    
    </form>
    </body>
    </html>
    
    upload.html

    同时多个Parser

    当同时使用多个parser时,rest framework会根据请求头content-type自动进行比对,并使用对应parser

    from django.conf.urls import url, include
    from web.views import TestView
    
    urlpatterns = [
        url(r'test/', TestView.as_view(), name='test'),
    ]
    #!/usr/bin/env python
    # -*- coding:utf-8 -*-
    from rest_framework.views import APIView
    from rest_framework.response import Response
    from rest_framework.request import Request
    from rest_framework.parsers import JSONParser, FormParser, MultiPartParser
    
    
    class TestView(APIView):
        parser_classes = [JSONParser, FormParser, MultiPartParser, ]
    
        def post(self, request, *args, **kwargs):
            print(request.content_type)
    
            # 获取请求的值,并使用对应的JSONParser进行处理
            print(request.data)
            # application/x-www-form-urlencoded 或 multipart/form-data时,request.POST中才有值
            print(request.POST)
            print(request.FILES)
            return Response('POST请求,响应内容')
    
        def put(self, request, *args, **kwargs):
            return Response('PUT请求,响应内容')

    全局使用

    REST_FRAMEWORK = {
        'DEFAULT_PARSER_CLASSES':[
            'rest_framework.parsers.JSONParser'
            'rest_framework.parsers.FormParser'
            'rest_framework.parsers.MultiPartParser'
        ]
    
    }
    from django.conf.urls import url, include
    from web.views import TestView
    
    urlpatterns = [
        url(r'test/', TestView.as_view(), name='test'),
    ]
    
    urls.py
    #!/usr/bin/env python
    # -*- coding:utf-8 -*-
    from rest_framework.views import APIView
    from rest_framework.response import Response
    
    
    class TestView(APIView):
        def post(self, request, *args, **kwargs):
            print(request.content_type)
    
            # 获取请求的值,并使用对应的JSONParser进行处理
            print(request.data)
            # application/x-www-form-urlencoded 或 multipart/form-data时,request.POST中才有值
            print(request.POST)
            print(request.FILES)
            return Response('POST请求,响应内容')
    
        def put(self, request, *args, **kwargs):
            return Response('PUT请求,响应内容')
