Amazon S3将目录复制到另一个目录 [英] Amazon S3 copy the directory to another directory

问题描述

如何使用PHP API将包含子文件夹和文件的文件夹复制/复制到S3存储库中的另一个目录中？

How do i copy/duplicate a folder that contain sub-folders and files into another directory within the S3 bucket using PHP API?

$ s3-> copy_object 仅复制文件夹，但不能复制文件和子文件夹。

$s3->copy_object only copies the folder, but not the files and sub-folders inside.

我必须使用 $ s3-> list_objects 获取所有文件和目录，并在每个文件/目录上运行 $ s3-> copy_object ？

Do i have to use $s3->list_objects to get all files and directory and run $s3->copy_object on every single file/directory?

推荐答案

S3不是一个文件系统，它是一个对象存储。文件夹实际上并不存在任何有形的含义;一个文件夹只是你可以调用一个共享的前缀。换句话说，如果您创建 path / to / one 和 path / to / two ，那么它也不会导致路径和 path / to 存在。如果您看到它们，那是因为某些组件获取了一个对象列表，将它们的键分割为 / ，并决定将该列表显示为层次结构。

S3 is not a filesystem, it's an object store. Folders don't actually exist in any tangible sense; a folder is just something you can call a shared prefix. Put another way, if you create path/to/one and path/to/two, it doesn't also cause path and path/to to exist. If you see them, that's because some component took a list of objects, split their keys on /, and decided to display that list as a hierarchy.

您要将文件夹复制到另一个文件夹。将其改为S3条款，您要将具有相同前缀的所有对象复制到具有不同前缀的对象。这样做使得方法清除：使用一个前缀获取对象列表，然后复制每个对象。

You want to "duplicate a folder into another folder". Rephrasing this into S3 terms, you want to "duplicate all objects with the same prefix into objects with a different prefix". Saying it that way makes the method clear: get a list of objects with the one prefix, then copy each of them.
