禅道下载附件自动加txt后缀已解决悬赏5积分

还是不行,
/* 文件上传设置。 Upload settings. */
$config->file = new stdclass();
$config->file->dangers = 'php,php3,php4,phtml,php5,jsp,py,rb,asp,aspx,ashx,asa,cer,cdx,aspl,shtm,shtml,html,htm';
$config->file->allowed = 'txt,doc,docx,dot,wps,wri,pdf,ppt,pptx,xls,xlsx,ett,xlt,xlsm,csv,jpg,jpeg,png,psd,gif,ico,bmp,swf,avi,rmvb,rm,mp3,mp4,3gp,flv,mov,movie,rar,zip,bz,bz2,tar,gz,mpp,rp,pdm,vsdx,vsd,sql,xmind,mm,cpt,frm';
$config->file->storageType = 'fs'; // fs or s3

我的配置里已经添加了, 按照ChatGPT的建议, my.php中也添加了:
<?php
$config->file->mimes['cpt'] = 'application/octet-stream';
$config->file->mimes['frm'] = 'application/octet-stream';

下载文件后还是加txt后缀

另外不是上传文件, 而是下载文件
