用户发帖应用开发中,用户异步上传了图片,但最终帖子没发布,那么上传的图不就没有用了吗怎么处理这种情况?

思路:后台做一个专门的附件管理。对图片跟帖子做一个关联;如果帖子没有发布成功,说明上传的图片并未与帖子关联,然后删除图片就好了。对于附件要时刻注意,很多人就是利用这个漏洞发布违法图片,然后从你服务器调用,这样可能会让你摊上大事。

用户上传时图片应该是在一个临时目录,发表帖子后图片会被 move 或者 copy 到另外一个目录,然后服务器有 shell 定时清理临时目录,不知道这个答案满意否?

这个要考虑服务器对上传的文件的处理,是放在缓存的还是上传到目录
在逻辑上一般都会给用户选择的机会也就是草稿箱

异步上传了图片(说明图片上传成功了)的理由是为了使用图片,说明图片路径你已经搞到手,帖子发布是一个提交过程,帖子没发布意味着没有提交成功,那么提交不成功,你做点什么(比如说将对应路径下的图片删除)就可以了,这只是一个思路,你可以尝试一下。

服务器脚本 定期检查 删除 或者你记录下来 在特定时间请求一下服务器删除就行了
一般上传就上传了 几张图片 应该没什么关系的

看了楼上的答案,感觉思路好多,我之前的做法是图片存到数据库里了,然后每天定时跑程勋删除状态=发布失败的文件
