我有一些文件存儲在OpenStack Swift（或任何其他存儲系統(tǒng)）上。我的django應(yīng)用程序提供了基于瀏覽器的GUI，供用戶從Swift后端下載這些文件：(1) Each file will have a URL such as: http://domain.com/files/file1(2) User could use browser or any other client program based on HTTP to download files.我已經(jīng)測試了將靜態(tài)文件下載為：def download(request):    try:        #TODO        file_name = 'E:/sample.docx'        fsock = open(file_name,"r")        mime_type_guess = mimetypes.guess_type(file_name)        if mime_type_guess is not None:            response = HttpResponse(fsock, mimetype=mime_type_guess[0])          response['Content-Length'] = os.path.getsize(file_name)                 response['Content-Disposition'] = 'attachment; filename=' + file_name                            except IOError:        response = HttpResponseNotFound()    return response我的問題是：（1）我可以從下載視圖下載文件，但下載的文件大小始終為1k。這是什么問題（2）我仍然不知道如何為存儲在其他對象存儲后端（例如OpenStack Swift）上的動態(tài)文件下載提供服務(wù)？
