52破解的附件上传
起因
2024春节题,本来用Typora自动picgo传上自己的七牛oss,发到论坛后发现很多地区都无法查看图片,遂手动使用论坛的图片功能传了将近50张图(4个帖子),并从html代码中提取了img的src网址,回到MD中一一修改了img的网址(真 ** 累啊)(后来发现自己是真傻啊,哈哈哈哈哈)
https://www.52pojie.cn/misc.php?mod=faq&action=faq&id=29&messageid=36
但是,由于上传图片返回的链接是临时链接,需要传到附件/图片点击附件,插入的[attachimg]xxx[/attachimg]才是永久链接,遂又重新折腾了一遍,改到头皮发麻,于是诞生了该代码
