上篇有【文件上传】,算是完成了一个比较完整的项目。
1.下载页面
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
<div class="panel-body">
<table class="table File-List-index-Table">
<tr>
<th>Id</th>
<th>项目</th>
<th>名称</th>
<th>备注</th>
<th>上传时间</th>
<th>下载</th>
</tr>
{% if list == '' %}
<span></span>
{% else %}
{% for m in list %}
<tr>
<td>{{ m.id }}</td>
<td>{{ m.ProName }}</td>
<td>{{ m.Filename }}</td>
<td>{{ m.Content }}</td>
<td>
<script>
document.write((new Date({{ m.UpdateTime }} * 1000).toLocaleString()))
</script>
</td>
<td><a href="/download/?filepath={{ m.FileField }}">下载</a></td>
</tr>
{% endfor %}
{% endif %}
</table>
</div>
