从django 1.4.3中的媒体文件夹下载文件(上载的文件)

我正在使用django来设计处理uploading文件夹中downloadingmedia文件的基本网页

实际上文件已成功上传到媒体文件夹,文件也已成功下载,但underscore作为last charater file_one.pdf_附加到file_name,file_two.pdf_file_three.txt_ },urlpatterns = patterns('', url(r'^upload$', 'learn_django.views.upload'), url(r'^files_list$', 'learn_django.views.files_list'), url(r'^download/(?P<file_name>.+)$', 'learn_django.views.download'), ) if settings.DEBUG: urlpatterns = patterns('', url(r'^media/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT, 'show_indexes': True}), ) + urlpatterns 等,

以下是我的代码

urls.py

def upload(request):
    ......
    ....
    return render_to_response('uploads_form.html', {'form': form},context_instance=RequestContext(request))


def files_list(request):
    return render_to_response('files_list.html',{'total_files':os.listdir(settings.MEDIA_ROOT),'path':settings.MEDIA_ROOT},context_instance=RequestContext(request))

def download(request,file_name):
    file_path = settings.MEDIA_ROOT +'/'+ file_name
    file_wrapper = FileWrapper(file(file_path,'rb'))
    file_mimetype = mimetypes.guess_type(file_path)
    response = HttpResponse(file_wrapper, content_type=file_mimetype )
    response['X-Sendfile'] = file_path
    response['Content-Length'] = os.stat(file_path).st_size
    response['Content-Disposition'] = 'attachment; filename=%s/' % smart_str(file_name) 
    return response

views.py

<table border="1" colspan="2" width="100%">
   <tr>
     <th width="60%">File</td>
     <th width="40%">Download</td> 
   </tr>
 {% for file in total_files %}
   <tr>
     <td width="60%">{{file}}</td>
     <td width="40%" align="center"><a href="/download/{{file}}" style="text-decoration:None">Download here</a></td>
   </tr>
 {% endfor %}  
</table>

files_list.html

files_list.html

因此,在上述代码中,当文件成功上传到媒体时,它将被重定向到files_listdownload视图功能,这些功能以表格形式显示文件总数每个文件名旁边的下载链接。

因此,当我们点击下载锚链接时,将通过执行函数underscore下载相应的文件。

因此该文件已成功下载,但_ file_one.pdf_附加到文件名的最后一个,如file_two.pdf_file_three.txt_underscore等,

所以任何人都可以告诉我,上面的下载功能代码有什么问题,为什么file name附加到underscore以及如何从文件名中删除{{1}}。 ..

答案 0 :(得分:6)

在文件名后删除/

改变这个:

response['Content-Disposition'] = 'attachment; filename=%s/' % smart_str(file_name) 

到此:

response['Content-Disposition'] = 'attachment; filename=%s' % smart_str(file_name)

您的代码是正确的,但download中有一个冗余字符:

def download(request,file_name):
    file_path = settings.MEDIA_ROOT +'/'+ file_name
    file_wrapper = FileWrapper(file(file_path,'rb'))
    file_mimetype = mimetypes.guess_type(file_path)
    response = HttpResponse(file_wrapper, content_type=file_mimetype )
    response['X-Sendfile'] = file_path
    response['Content-Length'] = os.stat(file_path).st_size
    response['Content-Disposition'] = 'attachment; filename=%s/' % smart_str(file_name) 
    return response

在最后一行,filename属性有一个斜杠(/):filename=%s /

导致问题的原因。删除此斜杠,它可以正常工作。

这些都不是必需的。在HTML中,您可以使用<a download="{video.URL}">

下载媒体文件

例如:

<button class="btn btn-outline-info">
<a href="{{result.products.full_video.url}}" download="{{result.products.full_video.url}}" style="text-decoration:None" class="footer_link">Download<i class="fa fa-download"></i></a>
</button>

我通过替换解决了问题

response['Content-Disposition'] = 'attachment; filename=diploma_"' + str(someID) + '.pdf"'

使用

response['Content-Disposition'] = 'attachment; filename="diploma_{}{}"'.format(str(someID),'.pdf')
