如何使用django-storage sftp下载文件？
提问于 2018-05-31 15:23:20
我正在使用django存储模块将文件存储在使用sftp的位置，现在我们需要从sftp下载相同的文件。
有什么建议吗？
models.py
from storages.backends.sftpstorage import SFTPStorage
SFS = SFTPStorage()
class Configurations(BaseModel):
name = models.CharField(max_length=150, unique=True)
file = models.FileField(upload_to='configurations', storage=SFS)
descriptions = models.TextField(null=True, blank=True)settings.py
DEFAULT_FILE_STORAGE = 'storages.backends.sftpstorage.SFTPStorage'
SFTP_STORAGE_HOST = '127.0.0.1'
SFTP_STORAGE_ROOT = '/var/www/media/'
SFTP_STORAGE_PARAMS = {
'username': 'root',
'password': 'password',
'allow_agent': False,
'look_for_keys': False,
}
# SFTP_KNOWN_HOST_FILE = '~/.ssh/known_hosts'
SFTP_STORAGE_INTERACTIVE = Falseviews.py
from django.http import Http404
from rest_framework import viewsets
from rest_framework.parsers import MultiPartParser, FormParser
from .models import (CustomConfigurations)
from .serializers import (CustomConfigurationsSerializers)
class ToolCustomConfigurationsViewSet(viewsets.ModelViewSet):
queryset = CustomConfigurations.objects.all()
parser_classes = (FormParser, MultiPartParser,)
serializer_class = CustomConfigurationsSerializers
def get_queryset(self):
queryset = self.queryset.all().order_by('-id')
return querysetserializer.py
class CustomConfigurationsSerializers(serializers.ModelSerializer):
class Meta:
model = CustomConfigurations
fields = '__all__'Stack Overflow用户

以下是我的解决方案：
@action(methods=['get'], detail=True)
def download(self, request, pk=None):
try:
obj = CustomConfigurations.objects.get(id=pk)
except CustomConfigurations.DoesNotExist:
raise Http404
if SFS.exists(obj.file.name):
file = SFS._read(obj.file.name)
type, encoding = mimetypes.guess_type(obj.file.name)
response = HttpResponse(file, content_type=type)
response['Content-Disposition'] = u'attachment; filename="{filename}'.format(
filename=obj.file.name)
return response
raise Http404页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
