【问题描述】:
我有一组文档(.pptx 文件),我希望将其提供给用户下载。我为此目的使用 django。我使用这些链接找出了一些部分:
having-django-serve-downloadable-files
我面临的问题是连接这些部分。相关代码片段-
settings.py文件
MEDIA_ROOT = PROJECT_DIR.parent.child('media')
MEDIA_URL = '/media/'
html 模板。变量slide_loc 具有文件位置(例如:path/to/file/filename.pptx)
<div class = 'project_data slide_loc'>
<a href = "{{ MEDIA_URL }}{{ slide_loc }}">Download </a>
</div>
views.py 文件
def doc_dwnldr(request, file_path, original_filename):
fp = open(file_path, 'rb')
response = HttpResponse(fp.read())
fp.close()
type, encoding = mimetypes.guess_type(original_filename)
if type is None:
type = 'application/octet-stream'
response['Content-Type'] = type
response['Content-Length'] = str(os.stat(file_path).st_size)
if encoding is not None:
response['Content-Encoding'] = encoding
# To inspect details for the below code, see http://greenbytes.de/tech/tc2231/
if u'WebKit' in request.META['HTTP_USER_AGENT']:
# Safari 3.0 and Chrome 2.0 accepts UTF-8 encoded string directly.
filename_header = 'filename=%s' % original_filename.encode('utf-8')
elif u'MSIE' in request.META['HTTP_USER_AGENT']:
# IE does not support internationalized filename at all.
# It can only recognize internationalized URL, so we do the trick via routing rules.
filename_header = ''
else:
# For others like Firefox, we follow RFC2231 (encoding extension in HTTP headers).
filename_header = 'filename*=UTF-8\'\'%s' % urllib.quote(original_filename.encode('utf-8'))
response['Content-Disposition'] = 'attachment; ' + filename_header
return response
urls.py 文件
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT)
我正在寻找的细节是 - 当用户点击下载按钮时,我如何在 views.py 文件中映射 url 和 doc_dwnldr 函数
