Django Rest框架返回文件

使用Django Rest框架进行文件返回是一种常见的开发需求。Django Rest框架是一个基于Django的强大工具，用于构建RESTful API。在许多应用程序中，我们需要实现文件上传和下载的功能，这时候Django Rest框架提供的文件返回功能就派上了用场。

python
from rest_framework.views import APIView
from rest_framework.response import Response
from django.core.files.storage import default_storage
from django.core.files.base import ContentFile
class FileUploadView(APIView):
    def post(self, request):
        file = request.FILES['file']
        file_name = file.name
        file_path = default_storage.save(file_name, ContentFile(file.read()))
        return Response({'file_path': file_path})

python
from rest_framework.views import APIView
from rest_framework.response import Response
from django.http import FileResponse
class FileDownloadView(APIView):
    def get(self, request, file_path):
        file = default_storage.open(file_path, 'rb')
        response = FileResponse(file)
        return response

python
from rest_framework.views import APIView
from rest_framework.response import Response
from django.core.files.storage import default_storage
from django.core.files.base import ContentFile
from django.http import FileResponse
class AvatarUploadView(APIView):
    def post(self, request):
        file = request.FILES['avatar']
        file_name = file.name
        file_path = default_storage.save(file_name, ContentFile(file.read()))
        return Response({'avatar_path': file_path})
class AvatarDownloadView(APIView):
    def get(self, request, avatar_path):
        file = default_storage.open(avatar_path, 'rb')
        response = FileResponse(file)
        return response
