2.下载页面代码

def file_iterator(file_name, chunk_size=1024):
    with open(file_name) as f:
        while True:
            c = f.read(chunk_size)
            if c:
                yield c
            else:
                break

def FileDownload(request):
    if request.method == 'GET':
        FilePath = request.GET['filepath']
        FileName = str(FileInfo.objects.get(FileField=FilePath).FileName)
        response = StreamingHttpResponse(file_iterator(FilePath))
        response['Content-Type'] = 'application/octet-stream'
        response['Content-Disposition'] = 'attachment;filename=%s' % FileName
        return response
        # print FilePath
    else:
        return HttpResponse('method must be get')

4.URL配置

    url(r'^download/', views.FileDownload),

3.下载页面前端代码

                
            {% if list == '' %}
                
            {% else %}
                {% for m in list %}
                    
                {% endfor %}
            {% endif %}
