如何禁用对文件夹html页面的直接访问？

<FilesMatch "\.html$">
    Order allow,deny
    Deny from all
</FilesMatch>

<Directory "/path/to/your/html/folder">
    <FilesMatch "\.html$">
        Order allow,deny
        Deny from all
    </FilesMatch>
</Directory>

sudo systemctl restart apache2

location ~* \.html$ {
    deny all;
}

sudo systemctl restart nginx
