it seems there is problems with my server,
can’t create tmpfile() when upload, i will check ,thank you

it worked after set php upload_tmp_dir
and upgrade the system, now php version is 8.0.9
i don’t know what make it works

搬到新服务器从App上传图片一样，也没反应，报错也没有，还好想起来以前好像发生过，一搜索还找到了当初发的贴子，确实是upload_tmp_dir没设置的问题，按道理有默认的位置啊
