当他们在我的应用程序中单击下载时，我正在向客户端发送文件，但是，客户端没有下载文件，但控制台指示文件已发送。

显示.html.erb

<div class="col-10 music-detail">
    <hr/>
    <%= form_for :music, url: music_download_path do |f| %>
        <%= f.hidden_field :music_id, value: @music.id %>
        <%= f.submit :download, class:"download_btn "%>
        <span class="sownload_count"><%= @music.download_count%></span>
    <% end %>
</div>

音乐控制器.rb

def download
    music_id = params[:music][:music_id]

    music =  Music.find(music_id)

    if music.valid?
        music_rel_path = music.music_path

        music_file = gen_absolute_file_path music_rel_path

        send_file(music_file)

        download_count = music.download_count + 1

        music.update(download_count: download_count)

        redirect_to "/musics/#{music_id}"
    end
end

rails 服务器控制台输出指示文件已发送
