Django下载文件

Django下载文件

您错过了参数文档 _ root下划线。但是

serve

在生产中使用它是个坏主意。使用类似这样的东西：

import osfrom django.conf import settingsfrom django.http import HttpResponse, Http404def download(request, path):    file_path = os.path.join(settings.MEDIA_ROOT, path)    if os.path.exists(file_path):        with open(file_path, 'rb') as fh: response = HttpResponse(fh.read(), content_type="application/vnd.ms-excel") response['Content-Disposition'] = 'inline; filename=' + os.path.basename(file_path) return response    raise Http404
