Java AWS S3复制对象源密钥和目标密钥

我正在编写JAVA代码来复制AWSS3中的对象

CopyObjectRequest copyObjRequest = new CopyObjectRequest(srcbucket, srcKey, destbucket, destKey);              
s3Client.copyObject(copyObjRequest);

什么是源密钥和目标密钥？我在理论上读了很多书，但没有提到从哪里可以得到这些钥匙。也许我错过了一些部分

请帮我获取bucket的源和目标密钥。。。。 请提供一个例子…

来自：

“sourceKey”和“destinationKey”是您要复制的S3对象的键。“sourceKey”是现有对象的键，“destinationKey”是要用于源对象副本的键名

在同一个存储桶中复制对象：

CopyObjectRequest copyObjRequest = new CopyObjectRequest("myBucket", "myObject.txt", "myBucket", "myNewObject.txt");              
s3Client.copyObject(copyObjRequest);

CopyObjectRequest copyObjRequest = new CopyObjectRequest("myBucket", "myObject.txt", "myOtherBucket", "myNewObject.txt");              
s3Client.copyObject(copyObjRequest);

在不同的存储桶中复制对象：

CopyObjectRequest copyObjRequest = new CopyObjectRequest("myBucket", "myObject.txt", "myBucket", "myNewObject.txt");              
s3Client.copyObject(copyObjRequest);

CopyObjectRequest copyObjRequest = new CopyObjectRequest("myBucket", "myObject.txt", "myOtherBucket", "myNewObject.txt");              
s3Client.copyObject(copyObjRequest);

进一步阅读：

CopyObjectRequest copyObjRequest = new CopyObjectRequest("myBucket", "myObject.txt", "myBucket", "myNewObject.txt");              
s3Client.copyObject(copyObjRequest);

CopyObjectRequest copyObjRequest = new CopyObjectRequest("myBucket", "myObject.txt", "myOtherBucket", "myNewObject.txt");              
s3Client.copyObject(copyObjRequest);

如果我用外行语言说，sourcekey将是应该复制到目标存储桶上的源文件名？@Ajay Correct。组合的“sourceBucketName”和“sourceKey”将描述您希望在S3中复制的对象的完整位置。
