python 上传文件到SVN python如何上传文件

最近刚学python,遇到上传下载文件功能需求，记录下！

django web项目，前端上传控件用的是uploadify。

文件上传 - 后台view 的 Python代码如下：

@csrf_exempt
@require_http_methods(["POST"])
def uploadFiles(request):
try:
user = request.session.get('user')
allFimeNames = ""
#获取所有上传文件
files = request.FILES.getlist("file")
for file in files:
# 获取文件名 解析文件后缀 获取新文件名
oldName = file.name
filename = str(int(time.time() * 10))+"."+oldName.split(".")[1]
now = datetime.now()
filePath = os.path.join("developmentTask",str(user.get("userId"))+"-"+now.strftime('%Y-%m-%d'))
dirpath = os.path.join(settings.UPLOADFILES_DIRS , filePath)
#写入服务器
if not os.path.exists(dirpath):
os.makedirs(dirpath)
newFilePath = os.path.join(dirpath, filename)
with open(newFilePath, 'wb+') as destination:
for chunk in file.chunks():
destination.write(chunk)
#返回新文件名 多个用逗号隔开
allFimeNames = os.path.join(filePath,filename)
except Exception:
return JsonResponse(data={'error': "系统异常"}, status=400)
return JsonResponse(data={'filePath': allFimeNames})

request.FILES.getlist("file")此处的file 是前端页面的文件提交的名称，可以在uploadify中配置。

文件下载：

@csrf_exempt
@require_http_methods(["GET"])
def downloadFile(request):
filePath = request.GET.get("filepath")
fileName = request.GET.get("filename")
file_name = os.path.join(settings.UPLOADFILES_DIRS, filePath)
if os.path.exists(file_name):
def file_iterator(file_name, chunk_size=512):
with open(file_name) as f:
while True:
c = f.read(chunk_size)
if c:
yield c
else:
break
response = StreamingHttpResponse(file_iterator(file_name))
response['Content-Type'] = 'application/octet-stream'
response['Content-Disposition'] = 'attachment;filename="{0}"'.format(fileName)
return response
response = StreamingHttpResponse("文件不存在！")
response['Content-Type'] = 'application/octet-stream'
response['Content-Disposition'] = 'attachment;filename="{0}"'.format("")
return response
