强制MP3文件下载而不是流媒体

Question

我在根目录以外的其他目录中有一些mp3文件。

当用户点击指向mp3的链接时，不是下载，而是在大多数浏览器（主要是移动浏览器）中开始流式传输。

我尝试在.htaccess中添加以下代码，但没有运气

<FilesMatch "\.(?i:mp3)$">
  ForceType application/octet-stream
 Header set Content-Disposition attachment
</FilesMatch>

我的服务器是用apache和nginxcp（nginx管理员）构建的。任何人都可以帮助我吗？

编辑：以下是我的域vhost文件的已编辑文件。但是在我重建主机并重新启动nginx后，文件将更改为原始文件，代码“location~.mp3 $ {add_header Content-Disposition attachment;}”将消失。

server {
          error_log /var/log/nginx/vhost-error_log warn;
          listen 198.xxx.xx.xxx:80;

        }
