python - Unable to Download file using flask with actual name -

i trying download file using flask. code follows

@app.route('/download') def down():     rpm = request.args.get('rpm')     root = '/home/rpmbuild/rpms/'     return send_from_directory(root,rpm) 

the name of file passed in url. when hit url, able download file name of file in download. need actual name of file. have tried send_file() downloading name download.

the "options" of send_from_directory same sendfile:

flask.send_file(filename_or_fp, mimetype=none, as_attachment=false,                 attachment_filename=none, add_etags=true,                 cache_timeout=none, conditional=false,                 last_modified=none)

so should call with:

@app.route('/download') def down():     rpm = request.args.get('rpm')     root = '/home/rpmbuild/rpms/'     return send_from_directory(root,rpm,attachment_filename='foo.ext')

where of course substitute 'foo.ext' name want give file. want set as_attachment parameter true.

in case want same name, can use os.path.basename(..) that:

import os  @app.route('/download') def down():     rpm = request.args.get('rpm')     root = '/home/rpmbuild/rpms/'     return send_from_directory(root,rpm,as_attachment=true,                                attachment_filename=os.path.basename(rpm))
