asp.net - 基于 Web 的大文件上传，带有 django 或 asp.net 中的恢复功能

Question

我们正在寻找一种开发基于 Web 的应用程序的方法，该应用程序应该能够上传大文件(大小高达 10 GB)并具有恢复功能。

我们希望使用 python/django 或 C#/asp.net 开发此应用程序。

如有任何建议，我们将不胜感激。

plupload Java 后端将支持任意大小的文件。

您需要将上传部分移植到 Django。事情会是这样的。虽然这不做任何校验和验证。

def fileUpload(request):
    """file upload for plupload"""
    if request.method == 'POST':
        name = request.REQUEST.get('name','')
        uploaded_file = request.FILES['file']
        if not name:
            name = uploaded_file.name
        name,ext = os.path.splitext(name)

        #check to see if a user has uploaded a file before, and if they have
        #not, make them a upload directory

        upload_dir = "/results/referenceLibrary/temp/"

        if not os.path.exists(upload_dir):
            return render_to_json({"error":"upload path does not exist"})

        dest_path = '%s%s%s%s' % (upload_dir,os.sep,name,ext)

        chunk = request.REQUEST.get('chunk','0')
        chunks = request.REQUEST.get('chunks','0')
        md5chunk = request.REQUEST.get('md5chunk', False)
        md5total = request.REQUEST.get('md5total', False)

        debug = [chunk, chunks, md5chunk, md5total]

        with open(dest_path,('wb' if chunk==0 else 'ab')) as f:
            for content in uploaded_file.chunks():
                f.write(content)

        if int(chunk) + 1 >= int(chunks):
            #the upload has finished
            pass

        return render_to_json({"chuck posted":debug})

    else:
        return render_to_json({"method":"only post here"})
