<p>密码：<input type="password" name="password"></p>
<p><input type="file" name="myfile"></p>
<p><input type="submit" value="提交"></p>
</form>
# views.py
def index(request):
file=request.FILES.get('myfile')
# 打开一个空文件，写入
with open(file.name,'wb') as f:
for line in file.chunks():
f.write(line)
return HttpResponse('文件上传成功')
