         location / {    
          root   /var/ftp/;
          if ($request_filename ~* ^.*?\.(txt|doc|pdf|rar|gz|zip|docx|exe|xlsx|ppt|pptx)$){
            add_header Content-Disposition: ‘attachment;‘;

         autoindex     on;
         autoindex_exact_size   off;
         autoindex_localtime    on;
         allow   192.168.4.0/24;         #允许4段的所有地址访问
         allow   192.168.5.0/24;         #允许5段的所有地址访问
         deny    all;                     #禁止全部
