HTTP/1.0 301永久移動 - Django

我已經使用djangorestframework創建了一個API，但是當我在終端中使用python manage.py runserver命令時，它顯示「HTTP/1.0 301 Moved Permanently」錯誤。 This the Message which it shows HTTP/1.0 301永久移動 - Django

但很酷的是，當我在瀏覽器中運行它顯示數據。 This the result in Chrome

我想知道發生了它。

而在此POST調用也不起作用。

下面是代碼：

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
