僅處理請求頭content-type為application/json的請求體

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)

        # 獲取請求的值，並使用對應的JSONParser進行處理
        print(request.data)

        # application/x-www-form-urlencoded 或 multipart/form-data時，request.POST中才有值
        print(request.POST)
        print(request.FILES)

        return Response('POST請求，響應內容')

    def put(self, request, *args, **kwargs):
        return Response('PUT請求，響應內容')

僅處理請求頭content-type為application/x-www-form-urlencoded 的請求體

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)

        # 獲取請求的值，並使用對應的JSONParser進行處理
        print(request.data)

        # application/x-www-form-urlencoded 或 multipart/form-data時，request.POST中才有值
        print(request.POST)
        print(request.FILES)

        return Response('POST請求，響應內容')

    def put(self, request, *args, **kwargs):
        return Response('PUT請求，響應內容')

僅處理請求頭content-type為multipart/form-data的請求體

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)

        # 獲取請求的值，並使用對應的JSONParser進行處理
        print(request.data)
        # application/x-www-form-urlencoded 或 multipart/form-data時，request.POST中才有值
        print(request.POST)
        print(request.FILES)
        return Response('POST請求，響應內容')

    def put(self, request, *args, **kwargs):
        return Response('PUT請求，響應內容')

同時多個Parser

當同時使用多個parser時，rest framework會根據請求頭content-type自動進行比對，並使用對應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)

        # 獲取請求的值，並使用對應的JSONParser進行處理
        print(request.data)
        # application/x-www-form-urlencoded 或 multipart/form-data時，request.POST中才有值
        print(request.POST)
        print(request.FILES)
        return Response('POST請求，響應內容')

    def put(self, request, *args, **kwargs):
        return Response('PUT請求，響應內容')

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)

        # 獲取請求的值，並使用對應的JSONParser進行處理
        print(request.data)
        # application/x-www-form-urlencoded 或 multipart/form-data時，request.POST中才有值
        print(request.POST)
        print(request.FILES)
        return Response('POST請求，響應內容')

    def put(self, request, *args, **kwargs):
        return Response('PUT請求，響應內容')
