嗨，我是亚马逊的新手，几乎没有使用文件的想法。我正在尝试将缩略图上传到存储桶中。我可以在本地主机中上传映像，但不能在存储桶中上传。我可以将原始映像上传到存储桶，这是我的代码

我的原始文件已成功上传，但是在上传缩略图时出现以下错误，
Warning: S3::putBucket(): [BucketAlreadyOwnedByYou] Your previous request to create the named bucket succeeded and you already own it. in /Applications/XAMPP/xamppfiles/htdocs/image_thumbnail_creation_php/S3.php on line 188

有人能帮我吗？提前致谢...
试试这个：这对我有用
