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‘)

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‘)

    ]

}

        print(request.POST)
        print(request.FILES)
