【问题描述】：
我使用 djangorestframework 创建了一个 API，但是当我在终端中使用 python manage.py runserver 命令运行它时，它显示“HTTP/1.0 301 Moved Permanently”错误。This the Message which it shows p>
但很酷的是，当我在浏览器中运行它时，它会显示数据。 This the result in Chrome
我想知道发生了什么事。
在此 POST 调用也不起作用。
下面是代码：
serializers.py
from rest_framework import serializers
from snippets.models import Snippet
class SnippetSerializer(serializers.ModelSerializer):
class Meta:
model = Snippet
fields = ('title','code',)
def create(self, validated_data):
return Snippet.objects.create(**validated_data)
def update(self, instance, validated_data):
instance.title = validated_data.get('title', instance.title)
instance.code = validated_data.get('code', instance.code)
instance.save()
return instance
Views.py

from rest_framework.renderers import JSONRenderer
from rest_framework.parsers import JSONParser
from snippets.models import Snippet

content = JSONRenderer().render(data)
kwargs['content_type']='application/json'
super(JSONResponse, self).__init__(content, **kwargs)

def snippet_list(request):
"""

if request.method == 'GET':
snippets = Snippet.objects.all()
serializer = SnippetSerializer(snippets, many=True)
return JSONResponse(serializer.data)
elif request.method == 'POST':
data = JSONParser().parse(request)
serializer = SnippetSerializer(data=data)
if serializer.is_valid():
serializer.save()
return JSONResponse(serializer.data, status=201)
return JSONResponse(serializer.errors, status=400)
@csrf_exempt
def snippet_detail(request, pk):
"""

try:
snippet = Snippet.objects.get(pk=pk)
except Snippet.DoesNotExist:
return HttpResponse(status=404)
if request.method == 'GET':
serializer = SnippetSerializer(snippet)
return JSONResponse(serializer.data)
elif request.method == 'PUT':
data = JSONParser().parse(request)
serializer = SnippetSerializer(snippet, data=data)
if serializer.is_valid():
serializer.save()
return JSONResponse(serializer.data)
return JSONResponse(serializer.errors, status=400)
elif request.method == 'DELETE':
snippet.delete()
return HttpResponse(status=204)
模型.py
from __future__ import unicode_literals
from django.db import models
# Create your models here.
class Snippet(models.Model):
created = models.DateTimeField(auto_now_add=True)
title = models.CharField(max_length=100, blank=True, default='')
code = models.TextField()

ordering = ('created',)
