node.js - 如何使用他们的 sdk 在 AWS S3 中移动(而不是复制)文件？

Question

我需要将 AWS s3 存储桶中的文件移动到另一个位置，例如:

• 发件人:http://aws.xxxxx/xxxx/locationA/file.png
• 收件人:http://aws.xxxxx/xxxx/locationB/file.png

我查看了文档:https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html ，但没有发现任何关于移动或更新文件的提及(我想我可以更新文件 key 路径...)。

到目前为止，我似乎需要复制文件然后删除旧文件？有更直接的方法吗？

我当前复制然后删除旧文件的代码:

function moveFileInAws(fromLocation, toLocation, callback) {
  awsSdk.copyObject({
    Bucket: BUCKET_NAME,
    ACL: 'public-read',
    CopySource: fromLocation,
    Key: toLocation
  }, (err, data) => {
    if (err) {
        console.log(err)
        return callback("Couldn't copy files in directory")
    }
    // callback()
    awsSdk.deleteObject({ Key: fromLocation }, (err, data) => {
      if (err) {
        console.log("Couldn't delete files in directory")
        console.log(err)
        return callback("Couldn't delete files in directory")
      }
      callback()
    })
  })
}

基于此处的答案:AWS S3 - Move an object to a different folder其中用户@Michael-sqlbot 评论:

That's because S3, itself, doesn't have an atomic move or rename operation... so there isn't really an alternative

这里的文档:https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/examples-s3-objects.html#copy-object (对于 Java SDK，但在这里似乎很有用)注释:

You can use copyObject with deleteObject to move or rename an object, by first copying the object to a new name (you can use the same bucket as both the source and destination) and then deleting the object from its old location.

听起来 S3 的基础架构根本不支持在单个操作中移动或重命名。您必须复制，然后删除。
