Python、Flask＆Jinjaでディレクトリを開いて開く

Question

私は検索しましたが、回答が見つかりませんでした。

私はpythonに1週間新しく、私はFlaskでpythonを使ってファイルとフォルダを含むWebディレクトリを提供しています。

ファイルをダウンロードできますが、ディレクトリを開くときに404が表示されます。手伝ってくれますか。

{% block content %}

Answer 1

の代わりに：

<a href="download/{{ file.fullname|urlencode }}" class="label label-success"> 

やってみてください。

<a href="{{url_for('download', filename=file.fullname|urlencode)}}" class="label label-success"> 

See this for a practical.
